A 404 error with the message “Model not found” means the model identifier in your request does not match any model available through the W&B Inference API.

​
Why this happens

  • Incorrect model ID: The model name or path in your request is misspelled or formatted incorrectly.
  • Model is not available on W&B Inference: Not all models hosted on other providers are available through the W&B Inference API. The model you are requesting may not have been onboarded.
  • Using the wrong base URL: If you are pointing at a different provider’s endpoint but using a W&B API key, the model ID will not resolve correctly.
  • Model was removed: A model that was previously available may have been deprecated or removed.

​
What you can do

  1. Check the model ID
    • Verify the exact model identifier against the W&B Inference supported models list.
    • Model IDs are case-sensitive and typically use the format provider/model-name (for example, meta-llama/Llama-3.3-70B-Instruct).
  2. Confirm the base URL
    • The W&B Inference base URL is https://api.wandb.ai/v1. Ensure your client is pointed at this URL and not another provider’s endpoint.
  3. Request access to a new model
    • If the model you need is not currently supported, contact W&B support to request it be added.
