HTTP status

404 not_found_error

​
Typical cause

The model parameter references a model that doesn’t exist in Auriko’s canonical catalog, or the requested provider variant is not available.

​
Model ID format

Auriko resolves model by exact match, so the value must be:
  • A bare canonical ID — for example gpt-4o-mini-2024-07-18, not a vendor-prefixed form like openai/gpt-4o-mini.
  • Case-sensitive — GPT-4o-mini-2024-07-18 does not match gpt-4o-mini-2024-07-18.
Many models also accept a shorter alias (for example claude-opus-4-5, which resolves to claude-opus-4-5-20251101). Each model’s aliases are listed in its directory entry.

​
Resolution

Check the model ID against the models directory and retry with a valid model ID.
