MiniMax M3 has been retired from our catalogue. Its figures below are the last published rates; calls to it are no longer served, while the other model in this comparison is.
Which one, when
These two are close on paper: both minimax-m3 and qwen3.7-plus offer a 1000000-token context, text/image/video input with text output, and the same chat, code, reasoning, tools and long-context flags, with thinking that can be disabled, and both released 2026-06-01. The separation is rate card and output ceiling: qwen3.7-plus bills about 1.33x minimax-m3 on input ($0.4 vs $0.3), output ($1.6 vs $1.2) and cache reads ($0.08 vs $0.06), while minimax-m3 allows 524288 max output tokens against 65536, or 8x the room. Pick minimax-m3 for cheaper runs and very long single generations; pick qwen3.7-plus if you prefer Alibaba as the vendor.

Which is cheaper, MiniMax M3 or Qwen3.7 Plus?
MiniMax M3 is cheaper on the "Input / 1M tokens" row ($0.3 vs $0.4, 1.3× apart). Other rows may point the other way; the table above carries the full rate card, and real cost depends on your mix.
Can I A/B test MiniMax M3 against Qwen3.7 Plus without two integrations?
Yes. Both are served through the same OpenAI-compatible endpoint with one API key. Switching is a one-line change to the model id, so you can route a fraction of traffic to each and compare bills directly.
Do MiniMax M3 and Qwen3.7 Plus support prompt caching?
Yes. Both bill cache reads below their input rate, so warm-prefix workloads cost less than the list rates suggest. The exact cache-read rows are in the pricing table above.
