Starting this week I cant use grok code model anymore, every try I get
Sorry, your request failed. Please try again. Request id: Reason: Request Failed: 400 {"error":{"message":"model "grok-code-fast-1" not supported for vision","code":""}}

how is that ? what does it mean not supported for vision ?
I have copilot pro account, and use Sonet and GPT successful and up to few weeks back used grok code Fast 1 (preview) model as well

The error means the model “grok-code-fast-1” does not support vision-related tasks, like processing images or other media. This usually happens if the request you sent included unsupported content types or if OpenAI changed the access rules for that model. Even if you have a Copilot Pro account, some models can become restricted or deprecated over time. To fix this, make sure your request only includes text and check if the model is still available for your use. If problems continue, contacting OpenAI support would be the best option

it happen to every question ? even something like "what is the time now in california"

[Aqib121201]

The most likely cause is that the grok-code-fast-1 model was recently updated or deprecated, and its current configuration no longer accepts regular chat or general text requests. The “not supported for vision” part of the message usually appears when the client sends a request that includes parameters intended for models that handle images or multimodal inputs. This can also happen if the client library or Copilot extension hasn’t updated its model mapping yet.

To confirm, try switching to a different available model such as gpt-4 or gpt-4o from the same environment. If that works without errors, the issue is with the grok-code-fast-1 model rather than your account or setup.

If this validation succeeds, the next step is to check the Copilot or OpenAI changelog for any model access updates, since preview models like grok-code-fast-1 are often temporary and can be retired without notice. If you still need similar functionality, contact GitHub Copilot support through the in-product feedback menu or GitHub Support to confirm whether the model has been phased out or replaced.

If this solves your problem, please mark the answer as helpful so others can find it easily.
