DeepSeek V4.1-Flash vs MiniMax M3
Values come from DeepSeek V4.1-Flash and MiniMax M3, 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
- DeepSeek V4.1-Flash at $0.15/M against $0.3/M — 2.0× 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
- DeepSeek V4.1-Flash at $0.6/M against $1.2/M — 2.0× 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 V4.1-Flash under MIT (open-weight), MiniMax M3 under Open-weight (HuggingFace). Check the licences rather than assuming they permit the same commercial use.
- Recency
- DeepSeek V4.1-Flash shipped 101 days after MiniMax M3 (2026-09-10 vs 2026-06-01).
