Which should you choose?
Which is better: GPT-5.4 nano, MiniMax-M2.7 or MiniMax-M3.1-Flash-Preview?
MiniMax-M3.1-Flash-Preview is the better all-round choice, scoring 66/100 against GPT-5.4 nano (60) and MiniMax-M2.7 (34). It leads on context window. The score weighs inputs & features 60%, context window 40%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.
Which is cheaper, GPT-5.4 nano, MiniMax-M2.7 or MiniMax-M3.1-Flash-Preview?
GPT-5.4 nano is cheaper at $0.20 input / $1.25 output per million tokens (official OpenAI API price). MiniMax-M2.7 costs $0.30 input / $1.20 output per million tokens (official MiniMax (minimax.io) API price). At a typical mix of three input tokens to one output token, that is $0.463 per million tokens for GPT-5.4 nano versus $0.525 for MiniMax-M2.7 (1.1× as much). MiniMax-M3.1-Flash-Preview has no published per-token price.
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. GPT-5.4 nano has an ECI of 145.8, MiniMax-M2.7 has an ECI of 145.9 and MiniMax-M3.1-Flash-Preview has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for GPT-5.4 nano, MiniMax-M2.7 and MiniMax-M3.1-Flash-Preview yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. All three support tool calling for agent workflows.
Which has the bigger context window?
MiniMax-M3.1-Flash-Preview has the largest context window at 1,000,000 tokens, against 400,000 for GPT-5.4 nano and 204,800 for MiniMax-M2.7. Maximum output per response: GPT-5.4 nano up to 128,000, MiniMax-M2.7 up to 131,072, MiniMax-M3.1-Flash-Preview up to 512,000 tokens.
Which can read images, PDFs, audio or video?
GPT-5.4 nano accepts text and images; MiniMax-M2.7 accepts text; MiniMax-M3.1-Flash-Preview accepts text, images and video. MiniMax-M3.1-Flash-Preview handles the widest range of inputs.
Are any of these open source?
MiniMax-M2.7 publishes its weights and can be self-hosted; GPT-5.4 nano and MiniMax-M3.1-Flash-Preview is proprietary.
Which is newer?
MiniMax-M3.1-Flash-Preview is the newest, released Sep 27, 2026. MiniMax-M2.7 came out Mar 18, 2026; GPT-5.4 nano came out Mar 17, 2026. Knowledge cutoff: GPT-5.4 nano Aug 31, 2025.
How do you decide the winner?
Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Oct 4, 2026.
