Cerebras Qwen3-Coder Is Deprecated: OpenCode Migration

The setup originally published at this URL no longer works on Cerebras’s shared public API. Cerebras deprecated qwen-3-coder-480b on November 5, 2025. Keeping the old model in OpenCode can produce a model-not-found response.

Pick the migration path#

If you want to stay on the public Cerebras service, list the models available to your account and choose a current production model. Cerebras’s public catalog changes, so copy the ID returned by the API rather than reusing an old article.

If you specifically want Qwen, use Alibaba Model Studio or Requesty. Requesty’s current managed ID is qwen3.8-max, and its live catalog can route that model across several providers.

Update OpenCode for Requesty#

Store a Requesty key in REQUESTY_API_KEY, then add an OpenAI-compatible provider:

{
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "requesty-extra": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "Requesty",
      "options": {
        "baseURL": "https://router.requesty.ai/v1",
        "apiKey": "{env:REQUESTY_API_KEY}"
      },
      "models": {
        "qwen3.8-max": { "name": "Qwen3.8-Max" }
      }
    }
  },
  "model": "requesty-extra/qwen3.8-max"
}

Restart OpenCode, open the model picker, and confirm that Qwen3.8-Max appears. Test a read-only request before approving edits.

Remove the retired ID#

Search user and project OpenCode configuration for:

qwen-3-coder-480b

Remove every active reference, including fallback lists. A hidden fallback can keep generating errors after the primary model has been changed.
