Which should you choose?
Which is better: GPT-5.4 nano, Seed 2.0 Code or MiniMax-M2.7?
GPT-5.4 nano is the better all-round choice, scoring 63/100 against Seed 2.0 Code (57) and MiniMax-M2.7 (48). It leads on price and context window. Seed 2.0 Code wins on inputs & features. The score weighs price 50%, inputs & features 30%, context window 20%. 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, Seed 2.0 Code or MiniMax-M2.7?
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); Seed 2.0 Code costs $0.475 input / $2.37 output per million tokens (official Volcengine Ark 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) and $0.95 for Seed 2.0 Code (2.1× as much).
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, Seed 2.0 Code has not been scored yet and MiniMax-M2.7 has an ECI of 145.9.
Which is better for coding?
There are no published SWE-bench Verified results for GPT-5.4 nano, Seed 2.0 Code and MiniMax-M2.7 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?
GPT-5.4 nano has the largest context window at 400,000 tokens, against 262,144 for Seed 2.0 Code and 204,800 for MiniMax-M2.7. Maximum output per response: GPT-5.4 nano up to 128,000, Seed 2.0 Code up to 131,072, MiniMax-M2.7 up to 131,072 tokens.
Which can read images, PDFs, audio or video?
GPT-5.4 nano accepts text and images; Seed 2.0 Code accepts text, images and video; MiniMax-M2.7 accepts text. Seed 2.0 Code 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 Seed 2.0 Code is proprietary.
Which is newer?
MiniMax-M2.7 is the newest, released Mar 18, 2026. GPT-5.4 nano came out Mar 17, 2026; Seed 2.0 Code came out Feb 14, 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.
