What you get

AI Singapore’s OpenAI-compatible API for its Southeast Asian language models

Free models

No free model family is currently listed here; callable ids, where the row has them, are under Connect.

Limits, in the vendor’s words

10 requests/minute per account

The free API is intended for prototyping; production use is directed to cloud partners. The free-offer page names no model, while the model API docs publish the per-user rate. No token or credit budget or expiry is stated.

Where it is offered

The vendor names no country it keeps the offer from (source, read 2026-09-26).

  -H "Authorization: Bearer $SEA_LION_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{"model":"aisingapore/Qwen-SEA-LION-v4.5-27B-IT","messages":[{"role":"user","content":"2+2? MAKE NO MISTAKES."}]}'
