Hy4 preview
A solid pick for self-hosting and full data control.
Overview
Hy4 preview is a 770-billion-parameter MoE generalist from Tencent, released under an Apache 2.0 open-weight licence that permits commercial use. Its million-token context and agent/code orientation make it a serious contender, but it remains a preview: 30-day OpenRouter adoption sits at just 5.7% and no solid benchmarks are yet available. Self-hosted, it keeps all data on the client's own infrastructure regardless of the vendor's nationality; only the TokenHub-hosted API routes traffic through China. Its scale demands substantial server-grade hardware.
