GPT-5.4 Mini vs MiniMax M2.7

OpenAI · US  |  MiniMax · China · Updated June 2026

Quick verdict

Pick GPT-5.4 Mini for free for every chatgpt user or fast, low-cost general tasks. Pick MiniMax M2.7 for agentic and terminal coding well above its price tier (57.0 on terminal-bench 2, vendor-reported) or independently ranked 14th of 97 on the artificial analysis intelligence index. Choose MiniMax M2.7 if you need self-hosting or data privacy; GPT-5.4 Mini if you want a managed API.

GPT-5.4 Mini (OpenAI, US) and MiniMax M2.7 (MiniMax, China) line up two different AI ecosystems against each other — a comparison that is as much about cost philosophy and openness as raw capability. GPT-5.4 Mini is openAI's free, fast workhorse — capable general AI with no subscription needed. MiniMax M2.7 is a cheap open-weight agentic coder with near-frontier terminal scores — held back by a non-commercial licence and non-standard benchmarks. They diverge most on price, context window and open vs. closed weights — each quantified below from the models' real specs.

Who wins what

Free for every ChatGPT user

GPT-5.4 Mini

OpenAI's free, fast workhorse — capable general AI with no subscription needed — and it carries the larger 400K context.

Fast, low-cost general tasks

GPT-5.4 Mini

GPT-5.4 Mini lists fast, low-cost general tasks among its strengths; MiniMax M2.7 does not.

Subagent capabilities

GPT-5.4 Mini

GPT-5.4 Mini lists subagent capabilities among its strengths; MiniMax M2.7 does not.

Agentic and terminal coding well above its price tier (57.0 on Terminal-Bench 2, vendor-reported)

MiniMax M2.7

At $0.3/$1.2 per 1M tokens it undercuts GPT-5.4 Mini ($0.75/$4.5 per 1M tokens), and that gap compounds at volume.

Independently ranked 14th of 97 on the Artificial Analysis Intelligence Index

MiniMax M2.7

A cheap open-weight agentic coder with near-frontier terminal scores — held back by a non-commercial licence and non-standard benchmarks — and it runs cheaper at $0.3/$1.2 per 1M tokens.

Sparse mixture-of-experts — roughly 230B total but only ~10B active, so it runs on local hardware

MiniMax M2.7

Open weights make this possible at all — GPT-5.4 Mini is API-only, so it cannot leave the vendor's servers.

Lowest cost at scale

MiniMax M2.7

At $0.3/$1.2 per 1M tokens, it is the cheaper of the two — the gap dominates the bill on high-volume workloads.

Largest single-prompt input

GPT-5.4 Mini

Its 400K window is about 2× larger than MiniMax M2.7's 205K, fitting roughly 600 pages in one prompt.

Which should you pick?

A cost-sensitive startup shipping high volume

MiniMax M2.7

At $0.3/$1.2 per 1M tokens it undercuts GPT-5.4 Mini, and on millions of tokens that margin decides the monthly bill.

Someone analysing very long documents or codebases

GPT-5.4 Mini

Larger 400K window fits more in one prompt.

A team with data-privacy or self-hosting needs

MiniMax M2.7

Open weights let you run it on your own hardware; GPT-5.4 Mini is API-only.

Anyone whose priority is free for every chatgpt user

GPT-5.4 Mini

It is specifically built for that.

Anyone whose priority is agentic and terminal coding well above its price tier (57.0 on terminal-bench 2, vendor-reported)

MiniMax M2.7

That is its strongest area.

An enterprise with regional data-residency rules

GPT-5.4 Mini: where it fits

OpenAI's free, fast workhorse — capable general AI with no subscription needed. Released March 17, 2026 by OpenAI, it is built for free for every ChatGPT user, fast, low-cost general tasks, subagent capabilities, and native multimodal reasoning.

Its trade-offs are real: smaller context than flagship models, and not for the hardest reasoning. At $0.75 in / $4.5 out per million tokens, it sits in the budget price band.

MiniMax M2.7: where it fits

A cheap open-weight agentic coder with near-frontier terminal scores — held back by a non-commercial licence and non-standard benchmarks. Released March 18, 2026 by MiniMax, it is built for agentic and terminal coding well above its price tier (57.0 on Terminal-Bench 2, vendor-reported), independently ranked 14th of 97 on the Artificial Analysis Intelligence Index, sparse mixture-of-experts — roughly 230B total but only ~10B active, so it runs on local hardware, and served by five separate hosts at uniform pricing, so there is no provider lock-in.

Its trade-offs: open weights but a NON-COMMERCIAL licence — commercial use requires prior written authorisation from MiniMax, and at least one major tracker still mislabels it as MIT, reports SWE-Bench Pro instead of the standard Verified set, which blocks like-for-like comparison, and already superseded internally by M3, and its 205K context is small against 1M-class rivals. At $0.3 in / $1.2 out per million tokens, it sits in the budget price band.

The bottom line for this matchup

The defining split here is open vs. closed. MiniMax M2.7 gives you weights you control — self-host it, fine-tune it, keep data in-house, pay only for hardware. GPT-5.4 Mini gives you a managed, always-updated API with no infrastructure to run. Teams with GPUs, privacy requirements, or huge volume often favour the open model; teams that want zero ops and the latest capabilities favour the closed one. Capability is close enough that this operational question, not the benchmark, usually decides it.

Frequently asked questions

Is GPT-5.4 Mini or MiniMax M2.7 better for coding?

Public SWE-Bench figures are not available for either model, so the honest test is your own repository — run an identical real bug through both. By design, GPT-5.4 Mini leans toward free for every chatgpt user while MiniMax M2.7 leans toward agentic and terminal coding well above its price tier (57.0 on terminal-bench 2, vendor-reported), and that positioning usually predicts which feels better on your codebase.

Which is cheaper, GPT-5.4 Mini or MiniMax M2.7?

MiniMax M2.7 is open-weight, so self-hosting means no per-token fee (you pay for hardware instead), while GPT-5.4 Mini is API-metered at $0.75/$4.5 per 1M tokens. For most teams without GPUs, the API model is cheaper to start; at very high volume, self-hosting can win.

Which has the bigger context window?

GPT-5.4 Mini — 400K vs 205K, about 2× larger. Useful only if the model actually reasons over the full window, which not all do.

Can I use both GPT-5.4 Mini and MiniMax M2.7 together?

Yes — a multi-model platform like LumiChats gives you GPT-5.4 Mini, MiniMax M2.7 and 40+ others under one ₹69/day pass (about $1/day), so you can draft with one and cross-check with the other instead of buying two subscriptions.

Which is newer, GPT-5.4 Mini or MiniMax M2.7?

MiniMax M2.7 — released March 18, 2026, about 1 days after GPT-5.4 Mini.
