Chinda Opensource Thai LLM 4B: Sovereign AI for Thailand
Chinda Opensource Thai LLM 4B, developed by iApp Technology, is a 4 billion parameter model based on the Qwen3-4B architecture, designed to be a leading Thai language model. It is completely free and open-source under the Apache 2.0 License, allowing for commercial use, modification, and distribution.
Key Capabilities
- Advanced Thinking Mode: Achieves the highest score among Thai LLMs in the 4B category, offering superior reasoning for complex problems and dynamic switching between thinking and non-thinking modes for efficiency.
- Exceptional Thai Language Accuracy: Boasts 98.4% accuracy in Thai output, specifically fine-tuned to prevent unwanted foreign language generation.
- Optimized Performance: Demonstrates 37% better overall performance compared to its nearest alternative in benchmarks like AIME24, LiveCodeBench, and MATH500, particularly strong in math and code tasks.
- Resource Efficient: Designed for fast inference with minimal GPU memory consumption, suitable for mobile, laptop, and edge computing applications.
- Extended Context: Supports a native context length of 32,768 tokens, extendable up to 131,072 tokens with YaRN scaling.
Good For
- RAG Applications: Ideal for building Retrieval-Augmented Generation systems requiring data processing within Thai sovereignty.
- Mathematical Calculation & Code Assistance: Excels in reasoning for math problems and providing programming support.
- Mobile and Laptop Applications: Optimized as a Small Language Model for efficient deployment on personal devices.
- Commercial Use: Its Apache 2.0 license permits broad commercial and research applications without restrictions.
