Tencent's Hy3 preview has reached the top of the OpenRouter rankings, showing higher token usage than Claude. While DeepSeek Flash V4 also ranks highly, the rapid ascent of Hy3 is considered unusual.
Model quality is reported to be inferior to Claude Opus 4.7 and GPT 5.5, performing at a level comparable to other Chinese open-source models. Despite this, pricing is believed to be the driver behind the increased usage.
The input cost for Hy3 preview is $0.066 per million tokens, making it cheaper than the higher-ranked DeepSeek V4 Flash ($0.10). This pricing, which may be disproportionately low relative to its quality, likely encouraged adoption.
Since May 8, the model has been available only via paid plans, and usage has remained stable. This data indicates continued demand even after the transition from the free period.
On OpenRouter, SiliconFlow is the sole provider for Hy3 preview. Unlike other models supported by multiple providers, it is possible that the concentration of traffic through a single channel has influenced the rankings.
Usage via applications accounts for less than 1% of the total, differing from previous cases where a specific app's default setting change caused a surge. Analysis suggests this is either organic growth or a situation where the cost of spoofing remains high.
