Tencent ships hosted Hy4 while full GA weights remain pending
Tencent Cloud now lists the production Hy4 model as hy4 in TokenHub with a one-million-token context window, 960,000-token input limit, 64,000-token output limit, image understanding, structured output, function calling and caching. The earlier Apache-2.0 Hy4 preview weights remain public, but Tencent has not yet posted a distinct full Hy4 checkpoint and licence.
Why it matters: Teams can now test a documented hosted endpoint with concrete context and tool capabilities, while the difference between the production service and public preview checkpoint remains material for portability and auditability.
