Tencent has unveiled Hy4 Preview, a new open-weight AI model designed to rival top systems like OpenAI's GPT and Anthropic's Claude. Unlike proprietary models, Hy4 Preview offers free model weights for developers to download and use, with affordable API pricing starting at $0.042 per million cached input tokens. The model boasts 770 billion total parameters and can handle a one-million-token context window.
It utilizes a Mixture-of-Experts (MoE) architecture, activating only a subset of its parameters during processing. Hy4 Preview outperforms several leading AI models in tasks such as coding and productivity tests, although it lags behind some rivals in specific areas. Released on August 28, 2026, the model is accessible through Tencent Cloud, OpenRouter, and Tencent's AI applications, with model weights available in open-source repositories.
Tencent emphasizes that Hy4 Preview represents a significant leap forward in their AI development, outperforming its predecessor Hy3 in various benchmarks, especially in programming tasks, long-context processing, and handling external tools.
