Tencent's HY3 model processed 6.13 trillion tokens in a single week on OpenRouter, reaching the top of the platform's weekly usage rankings ahead of Xiaomi MiMo-V2.5 and DeepSeek V4 Flash, according to data published July 13. HY3 launched on July 6, 2026, when Tencent's Hy Team released the full general-availability upgrade to Hy3 Preview under the Apache License 2.0. OpenRouter listed a free route — tencent/hy3:free — on the same day, with a stated two-week promotional window running through July 21, 2026. Post-window pricing is set at $0.14 per million input tokens and $0.58 per million output tokens. The volume reflects individual developers discovering that swapping one URL in their existing coding tools routes every request to a 295-billion-parameter model at zero cost. The technical mechanism relies on the OpenAI Chat Completions API as the industry's de facto interface standard; any tool built to accept a custom base URL can be redirected to OpenRouter with two changes: the base URL and the model ID string.
