The signal

  1. Tencent open-sources Hy4 preview, a 770B-parameter model built to run parallel coding-agent sessions What happened: Tencent Hunyuan released and open-sourced Hy4 preview under Apache 2.0, a 770B total / 49B active parameter MoE model with a 1M-token context window; Tencent says it can coordinate multiple codex sessions in parallel and beat Codex working alone across eight benchmarks, and claims it edges GLM-5.3 and Kimi K3 on an internal 203-task blind eval. Why it matters: a major Chinese lab just put a frontier-scale, self-hostable open-weight model into the same coding-agent tier as GLM-5.3 and Kimi K3, with day-one API distribution through Tencent Cloud and OpenRouter. Confidence: Confirmed (the release itself) / Reported (the benchmark claims are Tencent’s own internal eval, not independently verified) Sources: Tencent (primary) · Bloomberg (independent) · Hugging Face (primary)
