Models and Costs

Understand exactly how the cost of each model available in Tess works according to its specifications. The values below always represent the lowest possible execution cost for each model.

Technical identifier (API Slug)

The API Slug column is the stable model identifier — the same value used in programmatic configuration (for example, model_override in Cowork JSON). Use the slug, not the display name. For a guide with a JSON example, see also Model slugs.
