Grok 4 vs MiniMax M2.7

xAI · US  |  MiniMax · China · Updated June 2026

Quick verdict

Pick Grok 4 for 256k context with native tool use or real-time data via x integration. 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; Grok 4 if you want a managed API.

Grok 4 (xAI, 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. Grok 4 is xAI's 2M-context model with live data access and strong reasoning chops. 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

256K context with native tool use

Grok 4

Its 256K window holds about 1.3× more than MiniMax M2.7's 205K in a single prompt.

Real-time data via X integration

Grok 4

XAI's 2M-context model with live data access and strong reasoning chops — and it carries the larger 256K context.

Strong academic reasoning

Grok 4

Grok 4 lists strong academic reasoning 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 Grok 4 ($3/$15 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 — Grok 4 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

Grok 4

Its 256K window is about 1.3× larger than MiniMax M2.7's 205K, fitting roughly 384 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 Grok 4, and on millions of tokens that margin decides the monthly bill.

Someone analysing very long documents or codebases

Grok 4

Larger 256K 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; Grok 4 is API-only.

Anyone whose priority is 256k context with native tool use

Grok 4

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

Grok 4: where it fits

XAI's 2M-context model with live data access and strong reasoning chops. Released July 9, 2025 by xAI, it is built for 256K context with native tool use, real-time data via X integration, strong academic reasoning, and no long-context surcharge.

Its trade-offs are real: smaller ecosystem than OpenAI/Google, and less independent benchmark coverage. At $3 in / $15 out per million tokens, it sits in the mid 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. Grok 4 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 Grok 4 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, Grok 4 leans toward 256k context with native tool use 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, Grok 4 or MiniMax M2.7?

MiniMax M2.7 is open-weight, so self-hosting means no per-token fee (you pay for hardware instead), while Grok 4 is API-metered at $3/$15 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?

Grok 4 — 256K vs 205K, about 1.3× larger. Useful only if the model actually reasons over the full window, which not all do.

Can I use both Grok 4 and MiniMax M2.7 together?

Yes — a multi-model platform like LumiChats gives you Grok 4, 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, Grok 4 or MiniMax M2.7?

MiniMax M2.7 — released March 18, 2026, about 8 months after Grok 4.
