When to choose each
GPT-4.1 mini
Best for
- Cost-sensitive long-context API evaluation
Watch out for
- Not in the pinned LiveBench snapshot; its independent scores here come from Epoch AI's own GPQA Diamond, FrontierMath and SimpleQA Verified runs
MiMo-V2.6-Pro
Best for
- Long-horizon agent and coding work across modalities
- High-volume batch workloads
Watch out for
- The weights ship as two checkpoints (RL and MOPD), and Xiaomi does not say which one the API serves
- The mimo-v2.6-pro-ultraspeed id costs ten times as much and has no Batch API
