# LLM Conversation Simulator

*Note* Heavy WIP, and ReadMe autogeneated, and outdated
A Python application that simulates conversations between Large Language Models (LLMs) for mental health care simulation. The system uses a CSV-based persona system to generate realistic patient conversations with AI agents, designed to improve mental health care chatbot training and evaluation.

A Python application that simulates conversations between two Large Language Models (LLMs) using LangChain. The architecture is designed to be extensible, allowing different LLM providers to be easily integrated.

## Features

- **Mental Health Personas**: CSV-based system with realistic patient personas including age, background, mental health context, and risk factors
- **Asynchronous Generation**: Concurrent conversation generation for efficient batch processing
- **Modular Architecture**: Abstract LLM interface allows for easy integration of different LLM providers
- **System Prompts**: Each LLM instance can be initialized with custom system prompts loaded from files
- **Multiple Prompt Options**: Pre-built prompts for different AI personalities (assistant, philosopher, creative, scientist, skeptic)
- **Early Stopping**: Conversations can end naturally when the first LLM signals completion
- **Conversation Tracking**: Full conversation history is maintained and can be saved to files
- **Early Stopping**: Conversations can end naturally when personas signal completion
- **Conversation Tracking**: Full conversation history is maintained with comprehensive logging
- **LangChain Integration**: Uses LangChain for robust LLM interactions

### Persona System

The system uses a CSV-based approach for managing mental health patient personas:

#### Persona Data Structure (`data/personas.csv`)
Each persona includes:
- **Demographics**: Name, Age, Gender, Background
- **Mental Health Context**: Current mental health situation
- **Risk Assessment**: Risk Type (e.g., Suicidal Intent, Self Harm) and Acuity (Low/Moderate/High)
- **Communication Style**: How the persona expresses themselves
- **Triggers/Stressors**: What causes distress
- **Sample Prompt**: Example of what they might say

#### Prompt Templating (`data/persona_prompt_template.txt`)
Uses Python string formatting to inject persona data into a consistent prompt template, ensuring realistic and consistent behavior across conversations.

## Usage

The basic usage involves loading prompt configurations and running a conversation:
### Basic Conversation Generation

```python
from llm_factory import LLMFactory
from conversation_simulator import ConversationSimulator
from utils.prompt_loader import load_prompt_config

# Load prompt configurations (model from model_config.json, prompt from prompts/)
config1 = load_prompt_config("assistant") # Model: claude-3-5-sonnet-20241022
config2 = load_prompt_config("philosopher") # Model: claude-3-opus-20240229

# Create LLM instances using models from separate configuration
llm1 = LLMFactory.create_llm(
model_name=config1["model"],
name="Assistant",
system_prompt=config1["system_prompt"]
)
from main_generate import generate_conversations

# Persona model configuration (the "patient")
persona_model_config = {
"model": "claude-sonnet-4-20250514",
"temperature": 0.7,
"max_tokens": 1000
}

llm2 = LLMFactory.create_llm(
model_name=config2["model"],
name="Philosopher",
system_prompt=config2["system_prompt"]
# Agent model configuration (the "therapist")
agent_model_config = {
"model": "claude-sonnet-4-20250514",
"prompt_name": "therapist", # Must match a prompt config file
"name": "Claude Sonnet",
"temperature": 0.7,
"max_tokens": 1000
}

# Generate conversations
results = await generate_conversations(
persona_model_config=persona_model_config,
agent_model_config=agent_model_config,
max_turns=5,
runs_per_prompt=3,
persona_names=["Alex M.", "Chloe Kim"], # Optional: filter specific personas
folder_name="custom_experiment" # Optional: custom output folder
)
```

# Run simulation with initial message from first prompt
simulator = ConversationSimulator(llm1, llm2)
conversation = simulator.start_conversation(config1["initial_message"], max_turns=5)
### Command Line Usage

```bash
python main_generate.py
```

The script will:
1. Load personas from `data/personas.csv`
2. Generate conversations between each persona and the agent
3. Run multiple iterations per persona (configurable)
4. Save conversations and logs to timestamped folders
5. Support early termination when personas indicate completion

### Supported Models

Currently supported models:
- **Claude**: `claude-3-5-sonnet-20241022`, `claude-3-opus-20240229`, `claude-3-sonnet-20240229`, `claude-3-haiku-20240307`
- **Claude**: `claude-3-5-sonnet-20241022`, `claude-3-opus-20240229`, `claude-3-sonnet-20240229`, `claude-3-haiku-20240307`, `claude-sonnet-4-20250514`
- **OpenAI**: `gpt-4`, `gpt-4-turbo`, `gpt-3.5-turbo`

### Custom Prompts and Models

The system uses **separated configuration** for better maintainability:
### Custom Personas and Prompts

#### 1. Create Prompt Files (`prompts/`)
Add `.txt` files containing system prompts and initial messages:
#### 1. Add New Personas (`data/personas.csv`)
Add new rows to the CSV file with the required fields:

```csv
Name,Age,Gender,Background,Mental Health Context,Communication Style,Trajectory of sharing,Sample Prompt,Triggers/Stressors,Risk Type,Acuity
New Patient,30,Female,Software engineer,Experiencing burnout,Direct and analytical,Open about work stress,"I can't focus at work anymore",Work pressure deadlines,Self Harm,Moderate Acuity
```
You are a helpful AI assistant. Keep your responses concise and informative.

---INITIAL_MESSAGE---
What do you think makes a good conversation?
```
#### 2. Modify Prompt Template (`data/persona_prompt_template.txt`)
Update the template to include new fields or modify behavior patterns.

#### 2. Configure Models (`model_config.json`)
Assign models to prompts in the JSON configuration:

```json
{
"prompt_models": {
"assistant": "claude-3-5-sonnet-20241022",
"philosopher": "claude-3-opus-20240229",
"gpt_assistant": "gpt-4",
"gpt_creative": "gpt-4-turbo",
"new_prompt": "claude-3-haiku-20240307"
},
"default_model": "claude-3-5-sonnet-20241022"
}
```

**Benefits of Separation:**
- **Clean Prompts**: Focus on personality and behavior, not technical details
- **Easy Model Changes**: Switch models for existing prompts without touching prompt files
- **Centralized Model Management**: All model assignments in one place
- **Version Control Friendly**: Prompt changes don't require model config changes
#### 3. Configure Models (`model_config.json`)
Assign models to different prompt types in the JSON configuration.

### Early Stopping

The conversation simulator supports natural conversation termination when the first LLM (conversation initiator) signals that the conversation is complete.
The conversation simulator supports natural conversation termination when personas signal completion:

**Termination Signals Detected:**
- Explicit endings: "goodbye", "bye", "farewell", "conversation over"
- Explicit endings: "Thank you, I'm done", "goodbye", "bye", "farewell"
- Natural conclusions: "in conclusion", "to conclude", "final thoughts"
- Polite endings: "thanks for", "pleasure talking", "great conversation"
- Direct signals: "i'm done", "let's end here", "nothing more to discuss"

**How It Works:**
1. Only the first LLM (conversation initiator) can trigger early termination
2. When termination signals are detected, the conversation ends immediately
3. The conversation history includes termination flags for analysis
1. Only personas (conversation initiators) can trigger early termination
2. Conversations require at least 3 turns before termination is allowed
3. When termination signals are detected, the conversation ends immediately
4. Both console output and saved files indicate early termination

**Example:**
## Configuration

### Model Settings

Model settings can be adjusted in the configuration dictionaries:

```python
# Conversation will end naturally if LLM1 says something like:
# "Thanks for the great discussion! I think we've covered everything. Goodbye!"
# Instead of continuing for the full max_turns
persona_model_config = {
"model": "claude-sonnet-4-20250514",
"temperature": 0.7, # Controls response creativity
"max_tokens": 1000 # Maximum response length
}
```

## Configuration
### Output Organization

Conversations are automatically organized into timestamped folders:

```
conversations/
├── p_claude_sonnet_4_20250514__a_claude_sonnet_4_20250514_20250120_143022_t5_r3/
│ ├── abc123_Alex_M_c3s_run1_20250120_143022_123.txt

│ └── def456_Chloe_Kim_c3s_run1_20250120_143022_456.log
```

Model settings can be adjusted in `config.py`:
### Logging

- Model name/version
- Temperature
- Max tokens
- Other provider-specific parameters
Comprehensive logging tracks:
- Conversation start/end times
- Each turn with speaker, input, and response
- Early termination events
- Performance metrics (duration, turn count)
- Error handling and debugging information
