Text API

Legacy text models

Older text model IDs that still work, with the current model to move to.

  • Every ID below still answers. New work should use the replacement.
  • Same endpoints, same key and same prices as when the model was current.

Use https://direct.beatapi.io as the base URL for text requests: it is not subject to Cloudflare’s 100-second limit, so a long non-streaming request is not cut off. https://api.beatapi.io also works and is the fallback if direct.beatapi.io is unreachable from your network. The key, models and prices are the same on both. Image and video APIs use https://api.beatapi.io only.

Older IDs stay callable so existing integrations do not break. Each row names the current model to move to; the protocol column shows how the model answers on each format.

  • Moving to the replacement is a change of the model string; the request format does not change.
  • Check the price table before switching: a replacement can have a different price and context window.
  • A legacy ID can be withdrawn later. GET /v1/models lists what your key can call today.
