Hunyuan Hy4-preview

Open weights only — Tencent sells no first-party per-token endpoint for it, so budget for GPUs (770B params) or a third-party host; the Apache-2.0 licence makes it the most commercially permissive frontier model here.

The provider publishes no per-token price for this model. Any price you see elsewhere belongs to a third-party host, and running the weights yourself has hardware costs instead.
