gpt-oss-120b vs MiniMax M2.7

OpenAI · US  |  MiniMax · China · Updated June 2026

Quick verdict

Pick gpt-oss-120b for self-hostable on a single 80gb h100 gpu via mxfp4 or configurable reasoning depth (low/medium/high). 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. On a tight budget at scale, gpt-oss-120b is the value pick.

gpt-oss-120b (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-oss-120b is openAI's open-weight 117B-parameter MoE reasoning model (5.1B active) that runs on a single 80GB GPU and approaches o4-mini on reasoning, coding, and tool use. 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 and context window — each quantified below from the models' real specs.

Who wins what

Self-hostable on a single 80GB H100 GPU via MXFP4

gpt-oss-120b

gpt-oss-120b lists self-hostable on a single 80GB H100 GPU via MXFP4 among its strengths; MiniMax M2.7 does not.

Configurable reasoning depth (low/medium/high)

gpt-oss-120b

gpt-oss-120b lists configurable reasoning depth (low/medium/high) among its strengths; MiniMax M2.7 does not.

Agentic tool use, function calling, and code execution

gpt-oss-120b

gpt-oss-120b lists agentic tool use, function calling, and code execution 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

A cheap open-weight agentic coder with near-frontier terminal scores — held back by a non-commercial licence and non-standard benchmarks — and it carries the larger 205K context.

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 is the newer of the two.

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

MiniMax M2.7

gpt-oss-120b is comparatively weak here — 131K context and 5.1B active params trail the largest frontier closed models

Lowest cost at scale

gpt-oss-120b

Its weights are open, so at volume you pay for your own hardware instead of MiniMax M2.7's $0.3/$1.2 per 1M tokens.

Largest single-prompt input

MiniMax M2.7

Its 205K window is about 1.6× larger than gpt-oss-120b's 131K, fitting roughly 307 pages in one prompt.

Which should you pick?

A cost-sensitive startup shipping high volume

gpt-oss-120b

At Open weight (self-host / free) it undercuts MiniMax M2.7, and on millions of tokens that margin decides the monthly bill.

Someone analysing very long documents or codebases

MiniMax M2.7

Larger 205K window fits more in one prompt.

Anyone whose priority is self-hostable on a single 80gb h100 gpu via mxfp4

gpt-oss-120b

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-oss-120b or MiniMax M2.7

Origin (US vs China) affects where data is processed and which compliance regime applies — check the provider's terms for your region.

gpt-oss-120b: where it fits

OpenAI's open-weight 117B-parameter MoE reasoning model (5.1B active) that runs on a single 80GB GPU and approaches o4-mini on reasoning, coding, and tool use. Released August 5, 2025 by OpenAI, it is built for self-hostable on a single 80GB H100 GPU via MXFP4, configurable reasoning depth (low/medium/high), agentic tool use, function calling, and code execution, and full chain-of-thought visibility for debugging.

Its trade-offs are real: text-only, no image, audio, or video input, and 131K context and 5.1B active params trail the largest frontier closed models. As an open-weight model, its running cost is your own hardware rather than a per-token fee.

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

This is less "which is smarter" and more "which ecosystem fits." gpt-oss-120b (US) and MiniMax M2.7 (China) differ on pricing philosophy, data-residency, and tooling as much as on raw scores. gpt-oss-120b is the cheaper option, which matters at volume. The pragmatic move is to run one real task through both and judge the outputs against your own constraints — including where your data is allowed to be processed.

Frequently asked questions

Is gpt-oss-120b or MiniMax M2.7 better for coding?

Public SWE-Bench figures are not available for MiniMax M2.7, so the honest test is your own repository — run an identical real bug through both. By design, gpt-oss-120b leans toward self-hostable on a single 80gb h100 gpu via mxfp4 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-oss-120b or MiniMax M2.7?

gpt-oss-120b is cheaper — Open weight (self-host / free) vs $0.3/$1.2 per 1M tokens.

Which has the bigger context window?

MiniMax M2.7 — 205K vs 131K, about 1.6× larger. Useful only if the model actually reasons over the full window, which not all do.

Can I use both gpt-oss-120b and MiniMax M2.7 together?

Yes — a multi-model platform like LumiChats gives you gpt-oss-120b, 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-oss-120b or MiniMax M2.7?

MiniMax M2.7 — released March 18, 2026, about 8 months after gpt-oss-120b.
