- This record represents the August 2026 Tencent Hy4 preview release at Hugging Face commit 705d81ee51566a186d645b74c974d642ef2828fe (last modified 2026-08-28), a new 770B/49B architecture rather than a Hy3 snapshot, together with the hy4-preview TokenHub API model. Earlier Hy generations and community quantizations remain separate boundaries.
