What you get

Thai-tuned open models from SCB 10X, the venture arm of Siam Commercial Bank, behind an OpenAI-compatible API whose FAQ calls it a research showcase and free to use

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

5 requests/second; 200 requests/minute per account per model; for typhoon-v2.5-30b-a3b-instruct

A free research showcase, with higher limits available by email. Usage data is collected to improve the model and API; the vendor says it is not shared with third parties. Production users are directed to Together AI. A key is minted in the playground after signup; no page read mentions a card. OCR has its own lower rates, separate from the coding model.

Where it is offered

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

What happens to what you send

What you send may be used to train or improve models. In the vendor’s words: “Yes, we are collecting usage data from the Typhoon API. We use this data to improve the model and the API.” (source).
