DeepSeek V4-Pro-0813 vs LongCat-2.0
Values come from DeepSeek V4-Pro-0813 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
- DeepSeek V4-Pro-0813 takes 1.0M against 1M — modestly more room in a single request.
- Input price
- LongCat-2.0 at $0.3/M against $0.66/M — 2.2× 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 $1.98/M — 1.7× cheaper to generate. Output dominates the bill on most agentic workloads, where the model writes far more than it reads.
- Weights
- Both publish weights — DeepSeek V4-Pro-0813 under MIT (open-weight, as reported), LongCat-2.0 under MIT (commercially permissive). Check the licences rather than assuming they permit the same commercial use.
- Recency
- DeepSeek V4-Pro-0813 shipped 44 days after LongCat-2.0 (2026-08-13 vs 2026-06-30).
