04 — Questions

Which should you choose?

Which is better: GPT-5.4 nano, Laguna S 2.1 or MiniMax-M2.7?

Laguna S 2.1 is the better all-round choice, scoring 69/100 against GPT-5.4 nano (63) and MiniMax-M2.7 (48). It leads on price and context window. GPT-5.4 nano 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, Laguna S 2.1 or MiniMax-M2.7?

Laguna S 2.1 is cheaper at $0.10 input / $0.20 output per million tokens (median across 4 API providers; free on Poolside). GPT-5.4 nano costs $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 $0.125 per million tokens for Laguna S 2.1 versus $0.463 for GPT-5.4 nano (3.7× as much) and $0.525 for MiniMax-M2.7 (4.2× 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, Laguna S 2.1 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, Laguna S 2.1 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?

Laguna S 2.1 has the largest context window at 1,048,576 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, Laguna S 2.1 up to 32,768, MiniMax-M2.7 up to 131,072 tokens.

GPT-5.4 nano accepts text and images; Laguna S 2.1 accepts text; MiniMax-M2.7 accepts text. GPT-5.4 nano handles the widest range of inputs.

Are any of these open source?

Laguna S 2.1 and MiniMax-M2.7 publishes its weights and can be self-hosted; GPT-5.4 nano is proprietary.

Which is newer?

Laguna S 2.1 is the newest, released Jul 21, 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.
