Models

Models are the LLM options available in Aegis. Each has a URL-safe slug (what you pass in model_slug on runs and evaluations), a display name, and supplier metadata. Use the tables 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. Numeric database ids are assigned at deploy time and are not part of the public contract; always send the slug.

• thinking — yes means the model is treated as a “thinking” / reasoning-style model in the product; no means it is not.
• latest — yes marks the current recommended variant within that supplier’s line where applicable; other rows show no. A supplier may have more than one latest model (for example a fast and a flagship option).

In API payloads, always use the slug (for example gpt-4o, gpt-5.5, or claude-sonnet-4-6).
