Tencent Previews 770B Hy4 Open Model

Tencent’s Hy4 preview combines a 770B-total/49B-active MoE, over-1M-token context, coding and research positioning, product integrations, and published API pricing. Claimed throughput gains and internal evaluations need independent validation; latency, over-verification, licensing, and access details keep it in preview rather than production-ready status.
