What happened
Tencent published Hy4 on 4 November 2026, describing it as a scaled-up version of Hy4 preview with vision input added for the first time and claimed gains in instruction following, long-context understanding, long-horizon tasks and deep research. The post positions Hy4 as putting the Hy family "among the strongest open-source models for the first time" and lists three access routes: Tencent Cloud TokenHub, OpenRouter, and Hy AI Studio. The Hacker News thread drew 263 points and 97 comments, but the excerpt is cut off before the benchmark table, parameter counts, licence terms, or any pricing detail.
Why it matters
Hy4 is reachable via OpenRouter, so you can benchmark it against your current model without provisioning anything on Tencent Cloud — worth doing if you need vision plus long-context in one cheap call. But the announcement text gives no parameter size, no licence, and no price, so you cannot yet decide whether it is safe to self-host or ship inside a product; treat the "strongest open-source" line as unverified until you read the licence and the benchmark image yourself.
Discussion angle
Run the same vision + long-context task through Hy4 on OpenRouter and your current model, then compare cost per successful output — and check whether the licence actually permits the use you have in mind.
