Exciting update: There’s a new leader in the Agent Arena among open models. MiMo V2.6 Pro by @XiaomiMiMo has landed the #1 spot with +3.8% net improvement!
Earlier this week we evolved the Bash Recovery signal in Agent Arena (more info in thread). With this update, the new top 5 open models are:
- #1 MiMo V2.6 Pro: +3.8%
- #2 Deepseek V4.1 Flash (Max): +3.0%
- #3 Hy4 preview: +2.9%
- #4 MiMo V2.6 Flash: +2.5%
- #5 GLM 5.2 (Max): +2.4%
MiMo V2.6 Pro ($0.11 cost per task) and Flash ($0.05 cost per task) are the only two open models on the Agent Arena Pareto frontier!
- Pro outperforms both #2 Deepseek V4.1 Flash while costing 15% less, and #3 Hy4 preview while costing 71% less.
- Flash is 1.3 percentage points below Pro but is 55% cheaper.
Congrats to the @XiaomiMiMo team on this contribution to the open ecosystem!
