Models & slugs
Every model is addressed by a slug in the form provider/model-name, for example moonshotai/kimi-k3. Pass the slug in the model field of any chat or completion request.
Browsing the catalog
The models page lists every available slug with context length and per-token pricing. Programmatic access is available at GET /v1/models, which returns the same list in OpenAI-compatible shape.
Versioning
Slugs without a date suffix track the provider's current version of that model. When a provider ships a major revision, the old slug keeps resolving to the old version and a new slug appears — your integration never changes underneath you without warning.
Pricing
List prices are aligned 1:1 with OpenRouter public pricing and billed per token against your balance. Input and output tokens are priced separately; cached input is billed at the discounted rate where the provider supports it.
