Typhoon is a family of open-source AI models built for the Thai language. The site describes it as Thailand's frontier AI research lab, working on large language models and multimodal Thai language technologies, with a focus on Thai language, knowledge and culture.
The current lineup includes a text model, a reasoning model, speech recognition models, a document OCR model, a vision model and a Thai-to-English translation model. Typhoon-S is presented as a research preview for minimal open post-training of sovereign LLMs. Typhoon-Si-Med-Thinking-4B is a research preview medical reasoning model. Typhoon Isan ASR models transcribe both Isan and general Thai speech, with a real-time version for deployment from laptops to enterprise systems. Typhoon OCR is a bilingual vision-language model for parsing Thai documents. Typhoon Translate handles Thai and English translation with control over tone, terminology and formatting.
The lab also publishes research. Recent work listed on the site includes ThaiOCRBench, a benchmark for assessing vision-language models on Thai documents, along with an Isan spelling standard and an Isan speech transcription convention intended to support linguistic research and AI training.
The models are aimed at researchers, developers and businesses that need Thai language AI. The site points to a Thai bank's data analytics team, which says it uses Typhoon for tasks such as text-to-SQL and retrieval-augmented generation.
To try the models, visitors can use the Try Now option on the site. The site links to Discord, GitHub, Hugging Face and X for community support and discussion. It also links to datasets, documentation, demo apps and a blog. The page does not state a price for the models.
