MiMo-V2.6-Pro vs LongCat-2.0
Values come from MiMo-V2.6-Pro and LongCat-2.0, where each is cited to its source. This page states no benchmark result and ranks neither model — it puts two published specifications next to each other. Where a lab has not published a figure, the row says so rather than guessing.

What actually differs
- Context window
- Identical — both accept 1M tokens, so context length is not a reason to pick either.
- Input price
- LongCat-2.0 at $0.3/M against $0.435/M — 1.4× cheaper to feed. Standard rates: one of these labs also quotes a lower cached-input tier, which applies only when a prefix is reused — see the full spec below.
- Output price
- MiMo-V2.6-Pro at $0.87/M against $1.2/M — 1.4× cheaper to generate. Output dominates the bill on most agentic workloads, where the model writes far more than it reads.
- Weights
- Both publish weights — MiMo-V2.6-Pro under MIT (open weights), LongCat-2.0 under MIT (commercially permissive). Check the licences rather than assuming they permit the same commercial use.
- Recency
- MiMo-V2.6-Pro shipped 84 days after LongCat-2.0 (2026-09-22 vs 2026-06-30).
