Tencent Claims Hy4 Model Rivals Top AI Systems, But Weights Are Not Yet Released
Tencent announced its new unreleased Hy4 large language model, claiming its performance in computer use approaches top systems like Claude Opus 5.5 and Kimi K3.1 Pro. However, the model weights have not been released to the public yet. If Tencent's claims hold true upon the release of the weights, Hy4 could become a major contender in the open-source AI landscape, particularly for complex desktop and browser automation tasks. It highlights the rapid closing performance gap between proprietary models and upcoming open alternatives. According to benchmarks provided by Tencent, Hy4 ranks closely alongside Claude Opus 5.5 in computer use capabilities. While the official model weights and system cards are planned for release in the coming days, users currently rely solely on company-provided evaluation data.
## BACKGROUND
Computer use is an advanced AI capability where a model operates a graphical user interface like a human by perceiving pixels, locating interface elements, and issuing low-level input commands. Large language models (LLMs) are advanced artificial intelligence systems trained on vast amounts of text data to understand, generate, and process human language.
