Reviewer's Guide

Adds audio STT/TTS compatibility aliases, updates the local-qwen-3.6 route to preserve thinking with a longer timeout, and introduces a new local-qwen-3.6-hass route with thinking disabled, wiring these models into the allowed models list.

File-Level Changes

Change	Details	Files
Update local-qwen-3.6 configuration to preserve thinking and allow longer-running requests.	Attach extra_body.chat_template_kwargs.preserve_thinking=true to local-qwen-3.6 litellm_params. Increase request_timeout for local-qwen-3.6 from 120s to 600s to accommodate longer inference. Keep existing api_base, api_key, and model mapping for local-qwen-3.6 unchanged.	litellm/config.yaml
Introduce a local-qwen-3.6-hass route with thinking disabled but sharing the same backend.	Add a new model_list entry mapping model_name local-qwen-3.6-hass to backend model openai/local-qwen-3.6-hass. Set extra_body.chat_template_kwargs.enable_thinking=false for the hass variant. Configure request_timeout=600s to match the long-running behavior of local-qwen-3.6.	litellm/config.yaml
Add audio STT/TTS compatibility aliases and expose them as allowed models.	Include whisper-1, gpt-4o-mini-tts, and tts-1 in litellm_settings.allowed_model_groups so they can be requested. Define whisper-1 and gpt-4o-mini-transcribe as audio_transcription aliases pointing to local openai/whisper-1 at 127.0.0.1:8084 with a 60s timeout. Define gpt-4o-mini-tts and tts-1 as audio_speech aliases pointing to openrouter/openai/tts-1 with a 60s timeout and mark them public.	litellm/config.yaml

Warning

Review limit reached

@sheepdestroyer, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 12 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Hey - I've left some high level feedback:

• You define the gpt-4o-mini-transcribe alias in model_list but don’t add it to litellm_settings.allowed_model_group, which may prevent it from being usable like the other audio aliases.
• For the new TTS aliases pointing to openrouter/openai/tts-1, consider explicitly configuring api_base/api_key here if they differ from global defaults to avoid environment-dependent behavior.
