OpenThai 2.0 — one open model that reads Thai documents, knows Thailand, and does agentic work

Today, together with the Artificial Intelligence Entrepreneur Association of Thailand (AIEAT), we are releasing OpenThai 2.0 — an open-source Thai vision-language model, 27B parameters, Apache 2.0, weights free on Hugging Face.
One month ago we released OpenThai 2.0 Legal, a specialist that knows Thai law by heart. OpenThai 2.0 is its generalist sibling, and the bigger release of the two: a single model that reads Thai documents and handwriting at specialist level, answers Thai knowledge questions in natural Thai, and calls tools reliably enough to run agents — while keeping its base model's general intelligence.
