OpenThaiGPT 1.5: A Thai-Centric Open Source Large Language Model
This provides an advanced open-source tool for Thai language processing, though it is incremental as it builds on existing models.
The researchers tackled the problem of developing a high-performance Thai language chat model by finetuning Qwen v2.5 on over 2,000,000 Thai instruction pairs, resulting in state-of-the-art performance on various Thai language tasks.
OpenThaiGPT 1.5 is an advanced Thai language chat model based on Qwen v2.5, finetuned on over 2,000,000 Thai instruction pairs. This report provides an engineering perspective on the model's development, capabilities, and performance. We discuss the model's architecture, training process, and key features, including multi-turn conversation support, Retrieval Augmented Generation (RAG) compatibility, and tool-calling functionality. Benchmark results demonstrate OpenThaiGPT 1.5's state-of-the-art performance on various Thai language tasks, outperforming other open-source Thai language models. We also address practical considerations such as GPU memory requirements and deployment strategies.
