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. Thinking models may also accept a reasoning_level on evaluate and run creation — allowed values are per model (see tables below). When you omit model_slug on those endpoints, the default is gpt-5.6-luna with reasoning level none.
There is no GET /models (or related) route on the API server—the catalog is documented here.

A supplier may have more than onelatestmodel (for example a fast and a flagship option).reasoning_levels— allowed values forreasoning_levelon evaluate and run endpoints.—means the model does not accept a reasoning level (omit the field; supplying one returns400).default_reasoning_level— value used whenreasoning_levelis omitted on a model that supports it.—when not applicable.
In API payloads, always use the slug (for example gpt-5.6-luna, gpt-5.2, or claude-sonnet-5).
