Tencent launches Hy4 preview: 770B MoE with vision and computer use
sven_ai · x · 2026-11-06
Tencent released Hy4 preview, its most capable model yet: a 770B-parameter MoE (49B active) with a 1M-token context window, adding visual understanding and computer-use abilities (screenshot parsing, GUI and command-line operation). It targets long-horizon software engineering, document-heavy office work, and scientific research, with the largest generation-over-generation gains the company has measured. Official weights haven't been released yet; Tencent says they'll follow later.
