Tencent just dropped Hy3 and honestly i wasn't expecting this from them:
- 295B MoE with 21B active parameters - up to 256K context - built for coding agents, planning, tool use, and long-context workflows - competitive across coding, agent, and reasoning benchmarks - open weights under Apache 2.0, friendly for commercial use - free API for 2 weeks on OpenRouter
open weights. open license. free trial so you can verify the results yourself instead of trusting a chart.
a year ago open models still felt a step behind on coding and agentic tasks. Hy3 is another sign that gap is closing faster than most people expected.
