Returns the catalog of models available to your account. OpenAI-compatible.

Response

{
  "object": "list",
  "data": [
    {
      "id": "gpt-oss-120b",
      "object": "model",
      "created": 1714521600,
      "owned_by": "cogito",
      "context_window": 131072
    },
    ...
  ]
}

Notes

Fine-tuned variants tied to your account appear in this list with their own slugs (e.g. ft:gpt-oss-120b:my-org:summary-v1).
The context_window field is a Cogito extension; standard OpenAI clients ignore it.

Retrieve one model

Use the OpenAI-compatible retrieve-model endpoint to fetch an entitled model by its exact, URL-encoded ID. This also works for a dedicated model that is callable but intentionally absent from the collection.

curl https://api.cogito.decart.ai/v1/models/<url-encoded-model-id> \
  -H "Authorization: Bearer $COGITO_API_KEY"

Rollout-enabled MoE models include routing_matrix, an additive Cogito field with the static format needed to decode router replay payloads. Fetch it once when the trainer starts; completion responses do not repeat it.

{
  "id": "<model_id>",
  "routing_matrix": {
    "dtype": "uint16",
    "shape": [60, 8]
  }
}
