Models

Models are the LLM options available in Aegis. Each has a stable numeric id, a URL-safe slug (what you pass in model_slug on runs and evaluations), a display name, and supplier metadata. Use the table below to pick a valid slug when creating runs or evaluations.

There is no GET /models (or related) route on the API server—the catalog is documented here.

• thinking — yes means the model is treated as a “thinking” / reasoning-style model in the product; no means it is not.
• latest — yes on exactly one model marks the current recommended “latest” line variant where applicable; other rows show no.

In API payloads, always use the slug (for example gpt-4o or gpt-5.4).
