[BOT ISSUE] Cerebras catalog: missing new models and massive staleness #453

Description

Gap

The Cerebras section of the model catalog has two problems:

1. Missing new models

Cerebras now serves these models that are not in the catalog:

  • qwen-3-235b-a22b-instruct-2507 — Qwen3 235B model (preview)
  • zai-glm-4.7 — Zhipu AI GLM-4.7 model (preview)

(Note: gpt-oss-120b is already in the catalog with Cerebras as a provider.)

2. Massive catalog staleness

Cerebras appears to have dramatically reduced their public model lineup. The current official docs list only ~4 models (llama3.1-8b, gpt-oss-120b, qwen-3-235b-a22b-instruct-2507, zai-glm-4.7), but the local catalog contains 16+ Cerebras models — nearly all of which are no longer on Cerebras's supported models page:

  • llama-4-scout-17b-16e-instruct
  • llama3.3-70b, llama3.2-3b, llama3.2-1b
  • llama3-3-70b, llama3-2-3b, llama3-2-1b, llama3-1-70b, llama3-1-8b, llama3-70b, llama3-8b
  • mistral-7b, mixtral-8x7b
  • wizardlm-2-7b, wizardlm-2-8x22b
  • nous-hermes-llama2-13b, dolphin-mixtral-8x7b

These should likely be marked as deprecated.

Official source

Local files inspected

  • packages/proxy/schema/model_list.json — Cerebras models scattered throughout the file (lines ~2658-2749)
  • packages/proxy/schema/models.ts — Cerebras is a supported endpoint type

Why high confidence

The Cerebras docs page is a straightforward list of supported models. The gap between the catalog (16+ models) and the current docs (~4 models) is unambiguous.
