| The catch | By SCB 10X, the venture arm of Siam Commercial Bank, focused on Thai-language models. The free catalog spans LLMs (typhoon-v2.5-30b-a3b-instruct), OCR (typhoon-ocr family) and realtime Thai ASR (typhoon-asr-realtime, typhoon-isan-asr-realtime) — the hosted API is OpenAI-compatible, including audio transcriptions. Beta, provided as-is with no formal support; usage data is collected to improve the model; SCB claims no rights in outputs.
