[Bug] Model configuration for "gpt-4.1-mini" is missing the "Streaming" feature toggle

Function Description

Description

I am using the OpenAI plugin (or a compatible provider) in Dify. I noticed that for the model listed as gpt-4.1-mini (which I believe corresponds to gpt-4o-mini), the Streaming toggle is missing from the "Parameters" settings panel.

However, for other models in the same list (e.g., gpt-5-mini), the Streaming toggle appears and functions correctly.

According to OpenAI documentation, the gpt-4o-mini model fully supports streaming. It seems the model configuration/schema in Dify is missing the streaming feature flag for this specific model ID.

Expected Behavior

The "Streaming" toggle (True/False) should be visible and selectable for the gpt-4.1-mini model, similar to other chat models.

Actual Behavior

The "Streaming" toggle is completely hidden in the UI for gpt-4.1-mini.

Screenshots

1. gpt-4.1-mini (Missing Streaming):

2. gpt-5-mini (Streaming Available - for comparison):

Additional Context

• Looking at the UI, it seems the backend configuration for gpt-4.1-mini might be missing features: - streaming or supports_streaming: true in the model definition file.
• Please update the model definition to enable streaming for this model.
