• Typhoon: Open-Source Language Technologies for Thai Language Knowledge, and Culture

  Dec 1, 2023

  Thai-optimized language models and leading industry research labs, coverage from llm alignment research, low-resource adaption to multimodal and reasoning capabilities. We aim to advance Thailand and help it become a builder, not just a user.

  Key Achievements

  Built Thailand's leading AI research lab from the ground up. Led Typhoon models to achieve 1M+ downloads and 30M+ API requests, with enterprise deployment at Toyota Leasing, TDRI, PEA, VISAI, and Siriraj Hospital. Won Techsauce Innovation Award 2024 and AWS GAIA 2025 selection ($1M credits).

  Impact

  Built Thailand's leading AI research lab from scratch. Models outperform GPT-4o & Gemini on Thai-specific benchmarks (OCR, ASR, translation, instruction-following) with up to 156× cost reduction. Deployed at Toyota, hospitals, and government agencies.

• SCB 10X

  Lead AI Scientist

  Feb2024 - Present

  Overview

  Lead AI Scientist at SCB 10X, leading the Typhoon Team - Thailand’s leading AI research lab. Built and deployed production LLMs achieving 1M+ downloads and 30M+ API requests, with enterprise adoption at Toyota, PEA, and major hospitals.

  Key Achievements

  • Founding member of the Typhoon Team, building it from the ground up into Thailand’s leading AI research lab
  • Led and launched multiple LLMs optimized for Thai, achieving over 1M downloads on Hugging Face and more than 30M API requests
  • Contributed as both an individual researcher and supervisor across the majority of Typhoon Lab’s projects

  Major Projects

  • Typhoon Family of Multimodal LLMs – Developed one of the first text, vision, and audio multimodal models in Southeast Asia. Deployed by TDRI, VISAI, Siriraj Hospital, the Office of the Education Council, and others.
  • Typhoon Audio2 – Among the first end-to-end speech LLMs in Southeast Asia.
  • Typhoon T1 – The first reasoning model developed in Southeast Asia.
  • Typhoon R1 – The most advanced reasoning LLM tailored for Thai, matching DeepSeek R1’s reasoning performance while surpassing it in Thai benchmarks.
  • Typhoon OCR – A next-generation bilingual vision-language model for document parsing, outperforming GPT-4o and Gemini 2.5 Flash in Thai document understanding. Currently used by multiple enterprise clients including PEA and Toyota Leasing.
  • Typhoon Translate – A lightweight Thai–English translation model optimized for edge devices, outperforming GPT-4o, Claude 3.7, and Gemini 2.5 Flash, with only 4B parameters enabling efficient edge deployment.
  • Typhoon ASR Real-Time – A real-time Thai speech-to-text model with streaming capabilities, trained from scratch using a Transducer architecture. Delivers performance comparable to Google and Azure solutions at 156× lower cost.
