Tencent's Hy4 is a quiet signal about model competition

Hy4 from Tencent hit OpenRouter with what commenters are calling 'ludicrous traction' almost immediately after preview release. The thread notes Hy3 was already being used for specific task types but had speed problems. Hy4 appears to address some of that. The bar charts in the official blog post are apparently drawn incorrectly, which is either a sign of rushed release or sloppy comms, but neither stopped people from using it.

The pattern: non-US frontier models are landing with real adoption, not just benchmark citations. Hy4 showing up with immediate OpenRouter traction means developers are treating it as a legitimate tool, not a curiosity. This is the same dynamic that played out with DeepSeek earlier in the year.

The implication for anyone building on top of a specific model provider is that the market is moving fast enough that model loyalty is a liability. The smart builders are routing through abstraction layers like OpenRouter precisely because they expect the rankings to keep shuffling.
