   Tencent Hunyuan launches Hy4 with vision and computer use

   Tencent Hunyuan launched the 770B-parameter Hy4 model on November 4 and made it selectable in the Yuanbao mobile app, PC client and web interface. According to Tencent, Hy4 adds native visual understanding, computer operation across interfaces and applications, and training for long-horizon agent tasks. Lei Technology, whose article was republished by 36Kr with authorization, conducted hands-on tests that included building an interactive webpage, analyzing an earnings-report screenshot and checking visa-document requirements across WeChat and local files. The report also cites Tencent’s internal testing and crowdsourced evaluations for its claimed reductions in hallucinations and financial-task performance; it provides no independent benchmarks for those claims.
