04 — Questions

Which should you choose?

Which is better: GPT-5 Nano or MiniMax-M2.7?

GPT-5 Nano is the better all-round choice, scoring 70/100 against MiniMax-M2.7 (61). It leads on price, inputs & features and context window. MiniMax-M2.7 wins on capability. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%.

Which is cheaper, GPT-5 Nano or MiniMax-M2.7?

GPT-5 Nano is cheaper at $0.05 input / $0.40 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 $0.138 per million tokens for GPT-5 Nano versus $0.525 for MiniMax-M2.7 (3.8× as much).

Which scores higher on benchmarks?

MiniMax-M2.7 scores higher on the Capabilities Index (ECI): MiniMax-M2.7 145.9 (#73 of 148) and GPT-5 Nano 139.4 (#102 of 148). The confidence ranges of the top two overlap (138.2–148.0 vs 134.9–141.7), so treat the gap as small.

Which is better for coding?

There are no published SWE-bench Verified results for GPT-5 Nano and MiniMax-M2.7 yet, so there is no like-for-like coding score. On overall capability, MiniMax-M2.7 leads, which tends to carry over to coding, but test on your own codebase. Both support tool calling for agent workflows.

Which has the bigger context window?

GPT-5 Nano has the largest context window at 400,000 tokens, against 204,800 for MiniMax-M2.7. Maximum output per response: GPT-5 Nano up to 128,000, MiniMax-M2.7 up to 131,072 tokens.

Which can read images, PDFs, audio or video?

GPT-5 Nano accepts text and images; MiniMax-M2.7 accepts text. GPT-5 Nano 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 Nano is proprietary.

Which is newer?

MiniMax-M2.7 is the newest, released Mar 18, 2026. GPT-5 Nano came out Aug 7, 2025. Knowledge cutoff: GPT-5 Nano May 30, 2024.

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.
