Tencent Unleashes Open-Source 295B-Parameter AI Model to Rival OpenAI

Tencent has open-sourced a massive new AI model, Hy3, boasting 295 billion parameters. Despite its enormous size, the model uses a mixture-of-experts architecture, activating only 21 billion parameters per query, which dramatically improves efficiency. It also features a 256,000-token context window, enabling it to process large amounts of text in one go. This open-source release positions Tencent as a direct challenger to OpenAI's closed models, offering developers and researchers free access to cutting-edge AI technology.
