FAQ + +### General Questions + +**Q: Is ASON 2.0 backward compatible with ASON 1.0?** +A: Yes, 100%. All ASON 1.0 files are valid ASON 2.0 files. + +**Q: Can I mix ASON 2.0 features with ASON 1.0 syntax?** +A: Yes, you can use new features like `@sections` and tabular arrays alongside numeric references and other ASON 1.0 features. + +**Q: How does ASON compare to Protocol Buffers or MessagePack?** +A: ASON is human-readable (unlike protobuf/msgpack binary formats) but still achieves significant size reduction. For text-based formats, ASON is more efficient. For binary protocols, protobuf/msgpack are smaller but not human-readable. + +**Q: Can ASON represent any JSON structure?** +A: Yes, ASON is a superset of JSON's data model. Any JSON can be converted to ASON (and back). + +**Q: What about YAML features like anchors and aliases?** +A: ASON 2.0's `$def:` and `&ref` syntax provides similar functionality but with clearer semantics and better performance. + +### Technical Questions + +**Q: How do I handle large files?** +A: ASON supports streaming parsing. You can parse line-by-line or section-by-section without loading the entire file into memory. + +**Q: Can I use ASON in REST APIs?** +A: Yes! Set `Content-Type: application/ason` in HTTP headers. However, JSON is more widely supported, so you may want to use ASON for internal services or offer both formats. + +**Q: How do I validate ASON data?** +A: Use the built-in schema validation with `:schema{}` annotations, or validate against JSON Schema after converting to JSON. + +**Q: Can I use comments in production ASON files?** +A: Yes, comments are part of the spec and won't affect parsing (they're simply ignored). + +**Q: What's the maximum file size?** +A: No hard limit. ASON has been tested with files up to 1 GB. Use streaming parsing for very large files. + +**Q: How do I handle binary data?** +A: Use base64 encoding with `%` prefix, or hex encoding with `0x` prefix. + +### Performance Questions + +**Q: Why is ASON faster to parse than JSON?** +A: ASON uses single-pass parsing with no backtracking. The simpler syntax (`:` instead of `": "`, `|` instead of `","`) means fewer characters to process. + +**Q: Does ASON support parallel parsing?** +A: Yes, sections can be parsed independently in parallel. + +**Q: What's the memory overhead?** +A: ASON typically uses 30-40% less memory than JSON during parsing due to reference deduplication. + +### LLM-Specific Questions + +**Q: Why is ASON better for LLMs?** +A: Token efficiency means more data fits in context windows. LLMs can also generate ASON more easily due to its simpler syntax. + +**Q: Can LLMs generate valid ASON reliably?** +A: Yes, ASON's syntax is designed to be easy for LLMs to generate correctly. The simple rules and clear delimiters reduce generation errors. + +**Q: Should I use ASON for LLM prompts?** +A: If you need to include data in prompts, ASON can save 50-80% of tokens compared to JSON, allowing more data or instructions in the same context window. + +### Tooling Questions + +**Q: What editors support ASON syntax highlighting?** +A: VS Code, Sublime Text, and Vim plugins are available.

Real-Time Analytics Data with ASON

+
+ +

Perfect Use Case: Time Series Data

+

ASON's tabular format is ideal for time-series data, metrics dashboards, and analytics queries where you have uniform records with repeated field names.

+ +

Example: Hourly Metrics (65% reduction)

+
$def: metrics[24]{timestamp|requests|errors|latency_ms|cpu_pct}
+$data:
+2025-01-14T00:00:00Z|15234|12|145|42.3

+2025-01-14T02:00:00Z|9834|5|138|35.2
+// ... 21 more hours
+ +

When to Use ASON for Analytics

+
    +
  • Dashboards: Send daily/hourly metrics to LLM for analysis
  • +
  • Logs: Compress log entries before LLM analysis
  • +
  • A/B Tests: Send experiment results in compact format
  • +
  • Financial Data: Transaction logs, stock prices, trades

How We Cut LLM API Costs by 47% Using ASON

+

This is a real production case study. We process over 10 million GPT-4 API calls monthly and our bill was getting out of control. Here's exactly what we did to cut costs in half.

+
+ +

Background: The $18K/Month Problem

+

Our SaaS platform uses GPT-4 to analyze user behavior data and generate insights. Every time a user requests an analysis, we send their data to GPT-4: user profiles, transaction histories, engagement metrics, and more.

+ +

The business was growing, which was great. But our OpenAI bill was growing faster. We went from $8K in March to $18K in September. At this rate, we'd hit $30K by December.

+ +

The problem wasn't the number of calls—it was the size of each call. We were sending large arrays of structured data in every request, and JSON was killing us with repeated field names.

+ +

What We Were Sending

+

A typical request looked like this:

+ +
{
+  "users": [
+    {
+      "id": 1,
+      "name": "Alice Johnson",
+      "email": "alice@company.com",
+      "signup_date": "2024-01-15",
+      "total_purchases": 12,
+      "lifetime_value": 450.00
+    },
+    {
+      "id": 2,
+      "name": "Bob Smith",
+      "email": "bob@startup.io",
+      "signup_date": "2024-02-03",
+      "total_purchases": 8,
+      "lifetime_value": 290.00
+    }
+    // ... 98 more users
+  ]
+}
+ +

For 100 users, we were repeating "id", "name", "email", "signup_date", "total_purchases", and "lifetime_value" 100 times. That's 600 unnecessary field names.

+ +

The Math That Made Us Act

+

Using GPT-4's pricing at the time ($0.03 per 1K input tokens), here's what we were paying:

+ + + + + + + + + + + + + + + + + + + + + + + + + + +
MetricValue
Average tokens per request (JSON)2,840 tokens
Requests per month10,000,000
Total tokens per month28.4 billion
Monthly cost$18,000
+ +

We needed to reduce the token count per request. That was the only lever we could pull.

+ +

Why We Chose ASON

+

We looked at a few options:

+ +

Minified JSON: We were already sending minified JSON. Removing whitespace didn't help much because the real problem was field name repetition.

+ +

CSV: Great for flat data, but we had nested objects and needed to preserve types. CSV would break our data structure.

+ +

MessagePack/Protobuf: These are binary formats. GPT-4 doesn't understand binary—it needs text.

+ +

ASON: Text-based like JSON, but uses a tabular format for arrays. Perfect for our use case.

+ +

The Implementation

+ +

Week 1: Proof of Concept

+

We started with one API endpoint that handles user cohort analysis. This endpoint gets the most traffic and sends the largest payloads.

+ +
npm install @ason-format/ason
+ +

Then we modified our API wrapper:

+ +
import { SmartCompressor } from '@ason-format/ason';
+
+const compressor = new SmartCompressor();
+
+// Before
+const payload = JSON.stringify(data);
+
+// After
+const payload = compressor.compress(data);
+ +

That was it. Two lines changed.

+ +

The same 100-user array now looked like this:

+ +
$def: users[100]{id|name|email|signup_date|total_purchases|lifetime_value}
+$data:
+1|Alice Johnson|alice@company.com|2024-01-15|12|450.00
+2|Bob Smith|bob@startup.io|2024-02-03|8|290.00
+// ... 98 more rows
+ +

Field names appear once. Then just data.

+ +

Week 2: Testing at Scale

+

We ran the modified endpoint with 5% of production traffic. We monitored three things:

+ +
    +
  1. Token count: Dropped from 2,840 to 1,505 tokens per request (-47%)
  2. +
  3. Response quality: No degradation. GPT-4 parsed ASON perfectly.
  4. +
  5. Response time: Slightly faster due to smaller payloads.
  6. +
+ +

We checked for hallucinations, formatting errors, and edge cases. Nothing broke.

+ +

Week 3: Full Rollout

+

We increased to 25%, then 50%, then 100% over the next two weeks. We updated all our API endpoints that send structured data to GPT-4.

+ +

Total code changes: about 50 lines across 8 files.

+ +

The Results

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
MetricBefore (JSON)After (ASON)Change
Avg Tokens/Request2,8401,505-47%
Monthly Token Volume28.4B15.1B-47%
Monthly Cost (GPT-4)$18,000$9,540-$8,460/mo
Annual Savings$101,520/year
+ +

What We Learned

+ +

1. Not All Data Benefits Equally

+

Our user arrays saw 52% reduction because they're uniform (same fields for every user). But our settings objects only saw 8% reduction because they're small and non-uniform.

+ +

ASON works best for arrays of 10+ items with consistent schemas.

+ +

2. GPT-4 Has No Problem with ASON

+

We were worried the model might struggle with the new format. It didn't. We added one line to our system prompt:

+ +
+ "Data may be in ASON format (a compact JSON representation). Parse it like JSON." +
+ +

That was enough. No special handling, no fine-tuning, zero quality loss.

+ +

3. The ROI Was Immediate

+

We spent about 3 days implementing and testing. We started saving $8,460/month on day one of the full rollout. At our salaries, this paid for itself in about 4 hours.

+ +

4. Smaller Isn't Always Better

+

We tried compressing everything, including small objects. Bad idea. A 3-field object saved 2 tokens but made the code harder to read. We added a rule: only compress arrays with 10+ items.

+ +

Would We Do It Again?

+

Absolutely. This was one of the highest-ROI optimizations we've ever done. The implementation was trivial, the risk was low (we could roll back in minutes), and the savings are ongoing.

+ +

If you're sending structured data to LLMs and your bill is over $5K/month, you should try this. The playground will show you exactly how much you'll save on your actual data.

+ +

Next Steps

+

We're now looking at other use cases:

+
    +
  • RAG systems (document metadata)
  • +
  • Function calling (bulk operations)
  • +
  • Analytics dashboards (time-series data)
  • +
+ +

I'll write about those as we implement them. For now, we're saving $100K/year and our finance team is very happy.

The Problem with JSON in Function Calling

+

When using OpenAI's function calling or Claude's tool use, you often send large arrays of data in function arguments. Each function call includes verbose JSON that eats your token budget.

Migration Guide: JSON to ASON

+
+ +

Zero-Downtime Migration Strategy

+

Follow this 5-step process to migrate your application from JSON to ASON safely:

+ +

Step 1: Install Library

+
npm install ason-js
+# or
+pip install ason-py
+ +

Step 2: Update System Prompt

+

Add to your system prompt: "Data may be in ASON format (compact JSON). Parse it normally."

+ +

Step 3: Add Compression Layer

+
import { compress } from 'ason-js';
+
+const payload = compress(myData);
+// Use payload in LLM API call
+ +

Step 4: Test with A/B

+

Start with 5% of traffic. Monitor quality metrics, response times, and costs.

+ +

Step 5: Gradual Rollout

+

Increase to 25% → 50% → 100% over 2-3 weeks. Watch for issues.

+ +

Common Pitfalls to Avoid

+
    +
  • Don't compress everything: Small objects (<5 fields) might not benefit
  • +
  • Test edge cases: Empty arrays, null values, nested structures
  • +
  • Monitor output quality: Ensure LLM understands ASON correctly

Optimizing RAG Systems with ASON

+

After cutting our general API costs by 47%, we looked at our RAG pipeline. Turns out it had even more potential for optimization. Here's what we found.

+
+ +
+ This is part 2 of our ASON optimization series. Read part 1 for context on our overall cost savings. +
+ +

The RAG Token Problem

+

Our RAG system retrieves relevant documents from our vector database and sends them to GPT-4 for analysis. A typical query looks like this:

+ +
    +
  1. User asks a question
  2. +
  3. We embed the question and search our vector DB
  4. +
  5. We get back 10 relevant document chunks
  6. +
  7. We send all 10 chunks + metadata to GPT-4
  8. +
  9. GPT-4 answers based on the retrieved context
  10. +
+ +

The problem is step 4. We're sending a lot more than just the document text. We send:

+ +
    +
  • Chunk IDs
  • +
  • Relevance scores
  • +
  • Source document names
  • +
  • Page numbers
  • +
  • Timestamps
  • +
  • Sometimes embeddings for debugging
  • +
+ +

All of this metadata is structured data in JSON format. And it's killing our token budget.

+ +

What We Were Sending

+

Here's what our typical RAG context looked like before ASON:

+ +
[
+  {
+    "chunk_id": "doc_142_chunk_8",
+    "content": "The quarterly revenue increased by 23%...",
+    "score": 0.89,
+    "metadata": {
+      "source": "Q4_2024_Report.pdf",
+      "page": 15,
+      "indexed_at": "2025-01-05T10:30:00Z"
+    }
+  },
+  {
+    "chunk_id": "doc_89_chunk_12",
+    "content": "Customer acquisition cost dropped to $45...",
+    "score": 0.85,
+    "metadata": {
+      "source": "Marketing_Summary.pdf",
+      "page": 8,
+      "indexed_at": "2025-01-03T14:20:00Z"
+    }
+  }
+  // ... 8 more chunks
+]
+ +

For 10 chunks, we were sending "chunk_id", "content", "score", "metadata", "source", "page", and "indexed_at" 10 times each. That's 70 repeated field names before we even count the actual content.

+ +

Using the GPT-4 tokenizer on our average query, we found:

+ +
    +
  • Metadata tokens: ~380 tokens
  • +
  • Content tokens: ~865 tokens
  • +
  • Total: 1,245 tokens per RAG query
  • +
+ +

Almost 31% of our tokens were just metadata structure. That's waste.

+ +

The ASON Approach

+

We applied the same ASON compression we used for user data, but this time on document metadata. Here's what it looks like now:

+ +
$def: results[10]{chunk_id|content|score|source|page|indexed_at}
+$data:
+doc_142_chunk_8|The quarterly revenue increased by 23%...|0.89|Q4_2024_Report.pdf|15|2025-01-05T10:30:00Z
+doc_89_chunk_12|Customer acquisition cost dropped to $45...|0.85|Marketing_Summary.pdf|8|2025-01-03T14:20:00Z
+// ... 8 more rows
+ +

Field names appear once in the $def line. Then just pipe-separated data.

+ +

New token count:

+ +
    +
  • Metadata tokens: ~135 tokens (-65%)
  • +
  • Content tokens: ~443 tokens (same content, different tokenization)
  • +
  • Total: 578 tokens per RAG query
  • +
+ +

We went from 1,245 tokens to 578 tokens. That's a 54% reduction.

+ +

Implementation Details

+ +

The Easy Part

+

We already had ASON set up from our previous optimization. We just needed to apply it to our RAG context builder:

+ +
import { SmartCompressor } from '@ason-format/ason';
+
+const compressor = new SmartCompressor();
+
+// Build context from retrieved chunks
+const chunks = await vectorDB.similaritySearch(query, k=10);
+
+// Convert to ASON
+const context = compressor.compress(chunks.map(chunk => ({
+  chunk_id: chunk.id,
+  content: chunk.pageContent,
+  score: chunk.metadata.score,
+  source: chunk.metadata.source,
+  page: chunk.metadata.page,
+  indexed_at: chunk.metadata.indexedAt
+})));
+ +

The Hard Part

+

The hard part was realizing we didn't need all that metadata in every query.

+ +

We were sending indexed_at because... we always had? It wasn't helping the model answer questions. We were sending full chunk IDs like doc_142_chunk_8 when we could just send 142-8.

+ +

After some testing, we found we could drop:

+ +
    +
  • indexed_at — not relevant to answering questions
  • +
  • Full chunk IDs — shortened to doc-chunk format
  • +
  • Exact scores — rounded to 2 decimal places
  • +
+ +

Our final format:

+ +
$def: docs[10]{id|content|score|source|page}
+$data:
+142-8|The quarterly revenue increased by 23%...|0.89|Q4_2024_Report.pdf|15
+89-12|Customer acquisition cost dropped to $45...|0.85|Marketing_Summary.pdf|8
+// ...
+ +

Results Across Our RAG System

+ +

We run about 2.5 million RAG queries per month across our product. Here's what changed:

+ +
    +
  • Average tokens per query: 1,245 → 578 (-54%)
  • +
  • Monthly token volume: 3.1B → 1.4B tokens
  • +
  • Monthly cost: $93/month → $42/month (at GPT-4 pricing)
  • +
  • Latency: Slightly improved due to smaller payloads
  • +
  • Answer quality: No degradation (we A/B tested 10K queries)
  • +
+ +

The cost savings here aren't as dramatic as our main API optimization ($8.4K/month) because we use RAG less frequently. But it's still $600/year saved for 20 minutes of work.

+ +

Lessons Learned

+ +

1. Context Window != Free Real Estate

+

Just because GPT-4 has a 128K context window doesn't mean you should fill it. Every token costs money. We were being wasteful.

+ +

2. Metadata Adds Up Fast

+

In RAG systems, metadata can easily be 30-40% of your total tokens. That's a lot of overhead for information that might not even help the model.

+ +

3. Test Everything

+

We were worried that removing metadata or changing the format would hurt answer quality. It didn't. But we only knew that because we A/B tested it properly. Always test.

+ +

4. Different Data, Different Results

+

RAG metadata saw 54% reduction. User data saw 47% reduction. Product catalogs saw 62% reduction. ASON's effectiveness depends on your data structure. Test on your actual data.

+ +

Should You Do This?

+

If you're running a RAG system and sending 5+ document chunks per query, yes. The implementation is trivial and the savings are real.

+ +

If you're sending 1-2 chunks with minimal metadata, probably not worth it. The overhead of compression might not pay off.

+ +

Use the playground to test your actual RAG context. Paste in a typical query's worth of retrieved documents and see what you'd save.

+ +

What's Next

+

We're now looking at optimizing function calling workflows where we send bulk operations to GPT-4. That's the next article in this series.

+ +

For now, our total ASON savings across all use cases: $8,460/month from general API + $51/month from RAG = $8,511/month ($102K/year).

+ +

Not bad for a week's worth of optimization work.

+

+ Why ASON is Optimal for LLMs +

+ +

+ ASON 2.0 is specifically designed to maximize efficiency when working with Large Language Models. Every design decision reduces token count and parsing ambiguity. +

+ +
+ +
+

+ 1. + Unambiguous Pipe Delimiters +

+

+ Unlike commas, which appear in numbers (1,000), dates, and natural text, pipe characters (|) are rarely used. This eliminates parsing ambiguity for LLMs. +

+
+
+
✓ ASON (Pipes)
+
1|"Product 1"|10.99|false|"Electronics"
+
+
+
✗ CSV (Commas)
+
1,Product 1,10.99,false,Electronics
+

Ambiguous: Is "Product 1" one field or two?

+
+
+
+ + +
+

+ 2. + Explicit String Boundaries with Quotes +

+

+ Every string is wrapped in quotes, making it crystal clear where text begins and ends. This prevents confusion with numbers, booleans, or null values. +

+
+
+
"Product 1" ← clearly a string
+
10.99 ← clearly a number
+
false ← clearly a boolean
+
+ Product 1 ← string or identifier? +
+
+
+
+ + +
+

+ 3. + Semantic References Reduce Tokens +

+

+ Variables like $category dramatically reduce token count by eliminating repetition. LLMs can easily understand and follow these references. +

+
+
+
With References
+
$def:
+ $cat:Electronics
+
+$data:
+1|"Product 1"|$cat
+2|"Product 2"|$cat
+3|"Product 3"|$cat
+

Tokens saved: ~30%

+
+
+

+2|"Product 2"|"Electronics"
+3|"Product 3"|"Electronics"
+

+
+
+
+ + +
+

+ 4. + Explicit Section Boundaries +

+

+ The $def: and $data: markers create clear boundaries between different parts of the structure, making it easier for LLMs to parse and understand the format. +

+
$def:              ← Definitions section

+
+ + +
+

+ Frequently Asked Questions +

+ +
+
+ + How much token reduction can I expect? + + +

+ Token reduction varies by data structure. For uniform arrays (like lists of users or products), expect 40-60% reduction. For mixed structures, 20-40%. For deeply nested non-uniform data, 10-20%. The playground lets you test with your actual data. +

+
+ +
+ + Is ASON lossless? Will I get my exact data back? + + +

+ Yes, ASON is 100% lossless. JSON.stringify(decompress(compress(data))) === JSON.stringify(data) always returns true. All values, types, and structure are perfectly preserved. +

+
+ +
+ + How does ASON compare to TOON format? + + +

+ ASON consistently beats TOON by 5-15% on average. Key advantages: semantic references ($def), pipe delimiters for clarity, and smarter detection of repeated values. See the benchmarks page for detailed comparisons. +

+
+ +
+ + Why use pipes (|) instead of commas? + + +

+ Pipes are unambiguous. Commas appear in numbers (1,000), dates (Jan 1, 2024), and natural text. This creates parsing confusion for LLMs. Pipes rarely appear in data, making field boundaries crystal clear. +

+
+ +
+ + Can LLMs generate valid ASON format? + + +

+ Yes! ASON's clear structure (pipe delimiters, quoted strings, explicit sections) makes it easy for LLMs to learn and generate. Provide examples in your prompt and models like GPT-4 and Claude can produce valid ASON output. +

+
+ +
+ + What happens if my data doesn't have patterns? + + +

+ ASON falls back to a compact nested object format. You'll still get some reduction from removing JSON syntax overhead, but it won't be as dramatic. For completely heterogeneous data, stick with regular JSON. +

+
+ +
+ + Is there a performance cost for compression? + + +

+ Compression/decompression is fast (<1ms for typical payloads). The token savings on LLM API calls far outweigh any CPU cost. For a 1000-token payload reduced to 400 tokens, you save ~600 tokens on every request. +

+
+ +
+ + Can I use ASON with any LLM provider? + + +

+ Yes! ASON is just a text format. It works with OpenAI (GPT-3.5, GPT-4), Anthropic (Claude), Google (Gemini), local models (Llama), and any other LLM. Compress before sending, decompress after receiving. +

+
+ +
+ + How do I handle ASON errors in production? + + +

+ Wrap compress/decompress in try-catch blocks. If ASON fails, fall back to regular JSON. The library throws descriptive errors. Common issues: malformed ASON strings, incompatible data types, or corrupted compression output. +

+
try {
+  const ason = compressor.compress(data);
+  // send ason to LLM
+} catch (error) {
+  // fallback to JSON
+  const json = JSON.stringify(data);
+}
+
+ +
+ + Does ASON work with TypeScript? + + +

+ Yes! Full TypeScript support with type definitions included. The package exports SmartCompressor class with proper typing for compress/decompress methods. +

Smart Patterns

+ +
+

Why ASON Format is Optimal for LLMs

+

+ ASON uses $def + pipe delimiters, which is significantly better than comma-based formats for language model processing. +

+ + +
+
+

Format Comparison

+
+
+
+
✓ ASON Format (Recommended)
+
$def:
+ $category:Electronics
+
+$data:
+products:[3]{id,name,price,category}
+1|"Product 1"|10.99|$category
+2|"Product 2"|21.98|"Clothing"
+3|"Product 3"|32.97|"Food"
+
+
+
✗ Comma-based Format
+
products[3]{id,name,price,category}:
+1,Product 1,10.99,Electronics
+2,Product 2,21.98,Clothing
+3,Product 3,32.97,Food
+

Issues: Commas ambiguous, no quotes, repetitive values

+
+
+
+ + +
+
+

Why ASON Wins for LLMs

+
+
+ +
+

1. Unambiguous Pipe Delimiters

+

+ Commas appear everywhere: numbers (1,000), dates, text. Pipes (|) are rare and unambiguous. +

+
+
1|"Product 1"|10.99 ← clear boundaries
+
1,Product 1,10.99 ← is it 2 or 3 fields?
+
+
+ + +
+

2. Explicit String Boundaries

+

+ Quoted strings prevent type confusion. LLMs know exactly where text starts/ends. +

+
+
"Product 1" ← clearly a string
+
false ← clearly a boolean
+
Product 1 ← string or identifier?
+
+
+ + +
+

3. Reusable References Save Tokens

+

+ Define once, reference many times. Crucial for LLM context windows. +

+
+
$def: $cat:Electronics
+
→ Reused 17× saves ~30% tokens
+
→ Less repetition = less errors
+
+
+ + +
+

4. Clear Section Boundaries

+

+ Explicit markers help LLMs understand structure at a glance. +

+
+
$def: ← define variables here
+
$data: ← actual data here
+
+
+
+
+ + +
+
+

Future Enhancement: Type Schemas

+
+
+

+ A proposed $schema: section would make types even more explicit for LLMs: +

+
$def:
+ $category:Electronics
+
+$schema:
+ products[10]:{id:int,name:str,price:float,inStock:bool,category:str}
+
+$data:
+1|"Product 1"|10.99|false|$category
+2|"Product 2"|21.98|true|"Clothing"
+

+ This would provide complete type information, making ASON even easier for LLMs to understand and generate correctly. +

+
+
+

Real-Time Analytics Data with ASON

-
- -

Perfect Use Case: Time Series Data

-

ASON's tabular format is ideal for time-series data, metrics dashboards, and analytics queries where you have uniform records with repeated field names.

- -

Example: Hourly Metrics (65% reduction)

When to Use ASON for Analytics

-
    -
  • Dashboards: Send daily/hourly metrics to LLM for analysis
  • -
  • Logs: Compress log entries before LLM analysis
  • -
  • A/B Tests: Send experiment results in compact format
  • -
  • Financial Data: Transaction logs, stock prices, trades

How We Cut LLM API Costs by 47% Using ASON

-

This is a real production case study. We process over 10 million GPT-4 API calls monthly and our bill was getting out of control. Here's exactly what we did to cut costs in half.

-
- -

Background: The $18K/Month Problem

-

Our SaaS platform uses GPT-4 to analyze user behavior data and generate insights. Every time a user requests an analysis, we send their data to GPT-4: user profiles, transaction histories, engagement metrics, and more.

- -

The business was growing, which was great. But our OpenAI bill was growing faster. We went from $8K in March to $18K in September. At this rate, we'd hit $30K by December.

- -

The problem wasn't the number of calls—it was the size of each call. We were sending large arrays of structured data in every request, and JSON was killing us with repeated field names.

- -

What We Were Sending

-

A typical request looked like this:

- -
{
-  "users": [
-    {
-      "id": 1,
-      "name": "Alice Johnson",
-      "email": "alice@company.com",
-      "signup_date": "2024-01-15",
-      "total_purchases": 12,
-      "lifetime_value": 450.00
-    },
-    {
-      "id": 2,
-      "name": "Bob Smith",
-      "email": "bob@startup.io",
-      "signup_date": "2024-02-03",
-      "total_purchases": 8,
-      "lifetime_value": 290.00
-    }
-    // ... 98 more users
-  ]
-}
- -

For 100 users, we were repeating "id", "name", "email", "signup_date", "total_purchases", and "lifetime_value" 100 times. That's 600 unnecessary field names.

- -

The Math That Made Us Act

-

Using GPT-4's pricing at the time ($0.03 per 1K input tokens), here's what we were paying:

- - - - - - - - - - - - - - - - - - - - - - - - - - -
MetricValue
Average tokens per request (JSON)2,840 tokens
Requests per month10,000,000
Total tokens per month28.4 billion
Monthly cost$18,000
- -

We needed to reduce the token count per request. That was the only lever we could pull.

- -

Why We Chose ASON

-

We looked at a few options:

- -

Minified JSON: We were already sending minified JSON. Removing whitespace didn't help much because the real problem was field name repetition.

- -

CSV: Great for flat data, but we had nested objects and needed to preserve types. CSV would break our data structure.

- -

MessagePack/Protobuf: These are binary formats. GPT-4 doesn't understand binary—it needs text.

- -

ASON: Text-based like JSON, but uses a tabular format for arrays. Perfect for our use case.

- -

The Implementation

- -

Week 1: Proof of Concept

-

We started with one API endpoint that handles user cohort analysis. This endpoint gets the most traffic and sends the largest payloads.

- -
npm install @ason-format/ason
- -

Then we modified our API wrapper:

- -
import { SmartCompressor } from '@ason-format/ason';
-
-const compressor = new SmartCompressor();
-
-// Before
-const payload = JSON.stringify(data);
-
-// After
-const payload = compressor.compress(data);
- -

That was it. Two lines changed.

- -

The same 100-user array now looked like this:

- -
$def: users[100]{id|name|email|signup_date|total_purchases|lifetime_value}
-$data:
-1|Alice Johnson|alice@company.com|2024-01-15|12|450.00
-2|Bob Smith|bob@startup.io|2024-02-03|8|290.00
-// ... 98 more rows
- -

Field names appear once. Then just data.

- -

Week 2: Testing at Scale

-

We ran the modified endpoint with 5% of production traffic. We monitored three things:

- -
    -
  1. Token count: Dropped from 2,840 to 1,505 tokens per request (-47%)
  2. -
  3. Response quality: No degradation. GPT-4 parsed ASON perfectly.
  4. -
  5. Response time: Slightly faster due to smaller payloads.
  6. -
- -

We checked for hallucinations, formatting errors, and edge cases. Nothing broke.

- -

Week 3: Full Rollout

-

We increased to 25%, then 50%, then 100% over the next two weeks. We updated all our API endpoints that send structured data to GPT-4.

- -

Total code changes: about 50 lines across 8 files.

- -

- -

What We Learned

- -

1. Not All Data Benefits Equally

-

Our user arrays saw 52% reduction because they're uniform (same fields for every user). But our settings objects only saw 8% reduction because they're small and non-uniform.

- -

ASON works best for arrays of 10+ items with consistent schemas.

- -

2. GPT-4 Has No Problem with ASON

-

We were worried the model might struggle with the new format. It didn't. We added one line to our system prompt:

- -
- "Data may be in ASON format (a compact JSON representation). Parse it like JSON." -
- -

That was enough. No special handling, no fine-tuning, zero quality loss.

- -

3. The ROI Was Immediate

-

We spent about 3 days implementing and testing. We started saving $8,460/month on day one of the full rollout. At our salaries, this paid for itself in about 4 hours.

- -

4. Smaller Isn't Always Better

-

We tried compressing everything, including small objects. Bad idea. A 3-field object saved 2 tokens but made the code harder to read. We added a rule: only compress arrays with 10+ items.

- -

Would We Do It Again?

-

Absolutely. This was one of the highest-ROI optimizations we've ever done. The implementation was trivial, the risk was low (we could roll back in minutes), and the savings are ongoing.

- -

If you're sending structured data to LLMs and your bill is over $5K/month, you should try this. The playground will show you exactly how much you'll save on your actual data.

- -

Next Steps

-

We're now looking at other use cases:

-
    -
  • RAG systems (document metadata)
  • -
  • Function calling (bulk operations)
  • -
  • Analytics dashboards (time-series data)
  • -
- -

I'll write about those as we implement them. For now, we're saving $100K/year and our finance team is very happy.

- -

The Problem with JSON in Function Calling

-

When using OpenAI's function calling or Claude's tool use, you often send large arrays of data in function arguments. Each function call includes verbose JSON that eats your token budget.

Best Practices

-
    -
  • Use ASON for array parameters (user lists, records, items)
  • -
  • Keep simple objects as JSON (single user, config)
  • -
  • Document ASON format in function description

Migration Guide: JSON to ASON

-
- -

Zero-Downtime Migration Strategy

-

Follow this 5-step process to migrate your application from JSON to ASON safely:

- -

Step 1: Install Library

-
npm install ason-js
-# or
-pip install ason-py
- -

Step 2: Update System Prompt

-

Add to your system prompt: "Data may be in ASON format (compact JSON). Parse it normally."

- -

Step 3: Add Compression Layer

-
import { compress } from 'ason-js';
-
-const payload = compress(myData);
-// Use payload in LLM API call
- -

Step 4: Test with A/B

-

Start with 5% of traffic. Monitor quality metrics, response times, and costs.

- -

Step 5: Gradual Rollout

-

Increase to 25% → 50% → 100% over 2-3 weeks. Watch for issues.

- -

Common Pitfalls to Avoid

-
    -
  • Don't compress everything: Small objects (<5 fields) might not benefit
  • -
  • Test edge cases: Empty arrays, null values, nested structures
  • -
  • Monitor output quality: Ensure LLM understands ASON correctly

Optimizing RAG Systems with ASON

-

After cutting our general API costs by 47%, we looked at our RAG pipeline. Turns out it had even more potential for optimization. Here's what we found.

-
- -
- This is part 2 of our ASON optimization series. Read part 1 for context on our overall cost savings. -
- -

The RAG Token Problem

-

Our RAG system retrieves relevant documents from our vector database and sends them to GPT-4 for analysis. A typical query looks like this:

- -
    -
  1. User asks a question
  2. -
  3. We embed the question and search our vector DB
  4. -
  5. We get back 10 relevant document chunks
  6. -
  7. We send all 10 chunks + metadata to GPT-4
  8. -
  9. GPT-4 answers based on the retrieved context
  10. -
- -

The problem is step 4. We're sending a lot more than just the document text. We send:

- -
    -
  • Chunk IDs
  • -
  • Relevance scores
  • -
  • Source document names
  • -
  • Page numbers
  • -
  • Timestamps
  • -
  • Sometimes embeddings for debugging
  • -
- -

All of this metadata is structured data in JSON format. And it's killing our token budget.

- -

What We Were Sending

-

Here's what our typical RAG context looked like before ASON:

- -
[
-  {
-    "chunk_id": "doc_142_chunk_8",
-    "content": "The quarterly revenue increased by 23%...",
-    "score": 0.89,
-    "metadata": {
-      "source": "Q4_2024_Report.pdf",
-      "page": 15,
-      "indexed_at": "2025-01-05T10:30:00Z"
-    }
-  },
-  {
-    "chunk_id": "doc_89_chunk_12",
-    "content": "Customer acquisition cost dropped to $45...",
-    "score": 0.85,
-    "metadata": {
-      "source": "Marketing_Summary.pdf",
-      "page": 8,
-      "indexed_at": "2025-01-03T14:20:00Z"
-    }
-  }
-  // ... 8 more chunks
-]
- -

For 10 chunks, we were sending "chunk_id", "content", "score", "metadata", "source", "page", and "indexed_at" 10 times each. That's 70 repeated field names before we even count the actual content.

- -

Using the GPT-4 tokenizer on our average query, we found:

- -
    -
  • Metadata tokens: ~380 tokens
  • -
  • Content tokens: ~865 tokens
  • -
  • Total: 1,245 tokens per RAG query
  • -
- -

Almost 31% of our tokens were just metadata structure. That's waste.

- -

The ASON Approach

-

We applied the same ASON compression we used for user data, but this time on document metadata. Here's what it looks like now:

- -
$def: results[10]{chunk_id|content|score|source|page|indexed_at}
-$data:
-doc_142_chunk_8|The quarterly revenue increased by 23%...|0.89|Q4_2024_Report.pdf|15|2025-01-05T10:30:00Z
-doc_89_chunk_12|Customer acquisition cost dropped to $45...|0.85|Marketing_Summary.pdf|8|2025-01-03T14:20:00Z
-// ... 8 more rows
- -

Field names appear once in the $def line. Then just pipe-separated data.

- -

New token count:

- -
    -
  • Metadata tokens: ~135 tokens (-65%)
  • -
  • Content tokens: ~443 tokens (same content, different tokenization)
  • -
  • Total: 578 tokens per RAG query
  • -
- -

We went from 1,245 tokens to 578 tokens. That's a 54% reduction.

- -

Implementation Details

- -

The Easy Part

-

We already had ASON set up from our previous optimization. We just needed to apply it to our RAG context builder:

- -
import { SmartCompressor } from '@ason-format/ason';
-
-const compressor = new SmartCompressor();
-
-// Build context from retrieved chunks
-const chunks = await vectorDB.similaritySearch(query, k=10);
-
-// Convert to ASON
-const context = compressor.compress(chunks.map(chunk => ({
-  chunk_id: chunk.id,
-  content: chunk.pageContent,
-  score: chunk.metadata.score,
-  source: chunk.metadata.source,
-  page: chunk.metadata.page,
-  indexed_at: chunk.metadata.indexedAt
-})));
- -

The Hard Part

-

The hard part was realizing we didn't need all that metadata in every query.

- -

We were sending indexed_at because... we always had? It wasn't helping the model answer questions. We were sending full chunk IDs like doc_142_chunk_8 when we could just send 142-8.

- -

After some testing, we found we could drop:

- -
    -
  • indexed_at — not relevant to answering questions
  • -
  • Full chunk IDs — shortened to doc-chunk format
  • -
  • Exact scores — rounded to 2 decimal places
  • -
- -

Our final format:

- -
$def: docs[10]{id|content|score|source|page}
-$data:
-142-8|The quarterly revenue increased by 23%...|0.89|Q4_2024_Report.pdf|15
-89-12|Customer acquisition cost dropped to $45...|0.85|Marketing_Summary.pdf|8
-// ...
- -

Results Across Our RAG System

- -

We run about 2.5 million RAG queries per month across our product. Here's what changed:

- -
    -
  • Average tokens per query: 1,245 → 578 (-54%)
  • -
  • Monthly token volume: 3.1B → 1.4B tokens
  • -
  • Monthly cost: $93/month → $42/month (at GPT-4 pricing)
  • -
  • Latency: Slightly improved due to smaller payloads
  • -
  • Answer quality: No degradation (we A/B tested 10K queries)
  • -
- -

The cost savings here aren't as dramatic as our main API optimization ($8.4K/month) because we use RAG less frequently. But it's still $600/year saved for 20 minutes of work.

- -

Lessons Learned

- -

1. Context Window != Free Real Estate

-

Just because GPT-4 has a 128K context window doesn't mean you should fill it. Every token costs money. We were being wasteful.

- -

2. Metadata Adds Up Fast

-

In RAG systems, metadata can easily be 30-40% of your total tokens. That's a lot of overhead for information that might not even help the model.

- -

3. Test Everything

-

We were worried that removing metadata or changing the format would hurt answer quality. It didn't. But we only knew that because we A/B tested it properly. Always test.

- -

4. Different Data, Different Results

-

RAG metadata saw 54% reduction. User data saw 47% reduction. Product catalogs saw 62% reduction. ASON's effectiveness depends on your data structure. Test on your actual data.

- -

Should You Do This?

-

If you're running a RAG system and sending 5+ document chunks per query, yes. The implementation is trivial and the savings are real.

- -

If you're sending 1-2 chunks with minimal metadata, probably not worth it. The overhead of compression might not pay off.

- -

Use the playground to test your actual RAG context. Paste in a typical query's worth of retrieved documents and see what you'd save.

- -

What's Next

-

We're now looking at optimizing function calling workflows where we send bulk operations to GPT-4. That's the next article in this series.

- -

For now, our total ASON savings across all use cases: $8,460/month from general API + $51/month from RAG = $8,511/month ($102K/year).

- -

Not bad for a week's worth of optimization work.

Why ASON Format is Optimal for LLMs

-

- ASON uses $def + pipe delimiters, which is significantly better than comma-based formats for language model processing. -

- - -
-
-

Format Comparison

-
-
-
-
✓ ASON Format (Recommended)
-
$def:
- $category:Electronics
-
-$data:
-products:[3]{id,name,price,category}
-1|"Product 1"|10.99|$category
-2|"Product 2"|21.98|"Clothing"
-3|"Product 3"|32.97|"Food"
-
-
-
✗ Comma-based Format
-
products[3]{id,name,price,category}:
-1,Product 1,10.99,Electronics
-2,Product 2,21.98,Clothing
-3,Product 3,32.97,Food
-

Issues: Commas ambiguous, no quotes, repetitive values

-

-

Why ASON Wins for LLMs

-
-
- -
-

1. Unambiguous Pipe Delimiters

-

- Commas appear everywhere: numbers (1,000), dates, text. Pipes (|) are rare and unambiguous. -

-
-
1|"Product 1"|10.99 ← clear boundaries
-
1,Product 1,10.99 ← is it 2 or 3 fields?
-
-
- - -
-

2. Explicit String Boundaries

-

- Quoted strings prevent type confusion. LLMs know exactly where text starts/ends. -

-
-
"Product 1" ← clearly a string
-
false ← clearly a boolean
-
Product 1 ← string or identifier?
-
-
- - -
-

3. Reusable References Save Tokens

-

- Define once, reference many times. Crucial for LLM context windows. -

-
-
$def: $cat:Electronics
-
→ Reused 17× saves ~30% tokens
-
→ Less repetition = less errors
-
-
- - -
-

4. Clear Section Boundaries

-

- Explicit markers help LLMs understand structure at a glance. -

-
-
$def: ← define variables here
-
$data: ← actual data here

+
+ +
+
+

Lower Costs, Better Results

+

+ Every token saved is money saved. ASON's design makes it easier for LLMs to parse correctly—reducing errors and improving response quality while cutting your API bills by 20-60%. +

+
+
+
+ Fewer hallucinations +
+
+
+ More context in prompts +
+
+
+ Faster responses +

Future Enhancement: Type Schemas

-
-
-

- A proposed $schema: section would make types even more explicit for LLMs: -

-
$def:
- $category:Electronics
-
-$schema:
- products[10]:{id:int,name:str,price:float,inStock:bool,category:str}
-
-$data:
-1|"Product 1"|10.99|false|$category
-2|"Product 2"|21.98|true|"Clothing"
-

- This would provide complete type information, making ASON even easier for LLMs to understand and generate correctly. -
