Typhoon
Production-grade Thai LLM by SCB 10X with open weights
Typhoon is an open-source Thai LLM platform best for Thai banks, insurers, hospitals, and SaaS startups building Thai-first AI products on local infrastructure. Its SEA edge is depth — Typhoon 2.5 has the strongest Thai benchmark scores of any open LLM, and the family extends into Typhoon ASR Real-Time (19x faster than Whisper), Typhoon-Audio, and Typhoon OCR 1.5 for complete Thai speech and document workflows. The honest caveat: Typhoon is the right pick for Thai-first products specifically — for cross-SEA deployments, SEA-LION's broader language coverage is a better fit.
- ✓Strongest Thai benchmark scores of any open LLM in the market
- ✓Apache 2.0 open weights on Hugging Face — clean self-hosting story
- ✓Free hosted API at opentyphoon.ai removes friction for prototyping
- ✓Typhoon ASR Real-Time is 19x faster and 156x cheaper than Whisper for Thai audio
- ✓Backed by SCB 10X with credible long-term funding and bank-grade deployment experience
- ×Thai-only depth — wrong fit for cross-SEA multilingual deployments
- ×Free hosted API is rate-limited; production teams must self-host or wait for AWS-native production API
- ×Reviews count of 48 reflects an early-stage commercial ecosystem
- ×Open-source MLOps lift is real — not as turnkey as buying OpenAI access

The questions operators actually ask.
Is Typhoon better than GPT-4 for Thai?
Yes on Thai-specific benchmarks. Typhoon 2.5 was trained with a Thai-optimized tokenizer and Thai data, which produces better outputs on Thai conversations and Thai document tasks than GPT-4's generalist tokenizer.
Can Typhoon be self-hosted?
Yes. Open weights under Apache 2.0 on Hugging Face mean you can run Typhoon on your own GPU box or via vLLM. The AWS-native production API rolling out in 2026 will offer a managed alternative.
Does Typhoon support Isan dialect?
Yes via Typhoon ASR. Recent expansion into Isan dialect ASR makes Typhoon the only LLM family covering low-resource Thai dialects — useful for upcountry Thai voice deployments.
Is Typhoon free?
The open weights are free under Apache 2.0. The hosted API at opentyphoon.ai is free but rate-limited. Production at scale typically means self-hosting GPU cost or waiting for the AWS-native production API.
