[BOT ISSUE] Add databricks-gpt-5-4-mini and databricks-gemini-3-6-flash (Databricks)

[github-actions]

Summary

Two models listed on the Databricks Foundation Model APIs docs for pay-per-token serverless inference are missing from the model catalog: databricks-gpt-5-4-mini and databricks-gemini-3-6-flash.

Gap

Both base models exist in the catalog (gpt-5.4-mini and gemini-3.6-flash), but the Databricks-specific endpoint names do not. Other models in the same series already have Databricks variants (e.g., databricks-gpt-5-4, databricks-gpt-5-4-nano, databricks-gemini-3-5-flash).

Source verification

databricks-gpt-5-4-mini

Field	Value	Source
Model ID	databricks-gpt-5-4-mini	Databricks Foundation Model docs
Base model	gpt-5.4-mini	Already in model_list.json (line 172)
Context window	272,000 input / 128,000 output	Consistent with databricks-gpt-5-4-nano and Azure docs
Pricing	Not published per-model by Databricks	Skipped per provider constraint

databricks-gemini-3-6-flash

Field	Value	Source
Model ID	databricks-gemini-3-6-flash	Databricks Foundation Model docs
Base model	gemini-3.6-flash	Already in model_list.json (line 11122)
Context window	1,048,576 input / 65,536 output	Consistent with databricks-gemini-3-5-flash
Pricing	Not published per-model by Databricks	Skipped per provider constraint

Cross-source verification

• Both models confirmed on Databricks official documentation as available for pay-per-token serverless inference
• Base model gpt-5.4-mini confirmed on OpenAI docs and OpenAI pricing
• Base model gemini-3.6-flash confirmed on Google AI docs and Google pricing
• Not present in model_list.json (grep confirmed zero matches for both IDs)
• No existing GitHub issue covers these Databricks endpoints
• Specs derived from existing Databricks entries in the same model families (databricks-gpt-5-4-nano, databricks-gemini-3-5-flash)

Notes

• Databricks does not publish stable per-model pricing — pricing fields are omitted per provider constraint
• Databricks entries use format: "openai" (not the base model's native format) since Databricks exposes an OpenAI-compatible API
• reasoning is included for databricks-gemini-3-6-flash for consistency with the existing databricks-gemini-3-5-flash entry

Closing this bot issue because databricks-gpt-5-4-mini, databricks-gemini-3-6-flash are on the permanent sync-exclusion list (MANUAL_SYNC_EXCLUDED_MODELS / deprecated_model_ids.json in sync_models.ts) or a Perplexity Gateway (router) model the proxy cannot route, and must not be auto-added to the catalog.
