Current production findings

In the 2026-04-14 production recheck:
  • the endpoint returned 200
  • the top-level success field was true
  • the top-level object was list
  • the current model count was 605
  • the following models were confirmed present:
    • gpt-5.5
    • claude-opus-4-8

Pricing information

If you also need public pricing data, use the Pricing page. For programmatic confirmation of currently visible models, keep using GET /v1/models.
supported_endpoint_types on GET /v1/models only describes the interface styles the current model supports. openai maps to POST /v1/chat/completions, anthropic maps to POST /v1/messages, and only openai-response maps to POST /v1/responses. Claude currently exposes openai + anthropic, not openai-response.
