Tencent publishes Hy4 preview under Apache 2.0 for self-hosting and does not publish a first-party hosted token rate for this exact checkpoint. We represent the open-weight row as self-host/free-per-token before infrastructure costs; the separate FP8 checkpoint is a quantization of the same model rather than a separately priced API SKU.
