Mistral Large 4 vs LongCat-2.0
Values come from Mistral Large 4 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 $1.36/M — 4.5× 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
- LongCat-2.0 at $1.2/M against $4.18/M — 3.5× cheaper to generate. Output dominates the bill on most agentic workloads, where the model writes far more than it reads.
- Recency
- Mistral Large 4 shipped 98 days after LongCat-2.0 (2026-10-06 vs 2026-06-30).
