Kimi K2.7 Code vs MiniMax M3

Moonshot AI · China  |  MiniMax · China · Updated June 2026

Quick verdict

Pick Kimi K2.7 Code for long-horizon agentic software engineering or token-efficient reasoning (~30% fewer than k2.6). Pick MiniMax M3 for open-weight 428b moe (~23b active per token) with a 1m-token context or native multimodal input — text, image and video. On a tight budget at scale, MiniMax M3 is the value pick.

Kimi K2.7 Code (Moonshot AI) and MiniMax M3 (MiniMax) are two of the models people most often weigh against each other in 2026. Kimi K2.7 Code is moonshot AI's open-weight 1T-parameter MoE model (32B active) tuned for long-horizon agentic coding, always reasoning yet ~30% more token-efficient than K2.6. MiniMax M3 is miniMax's open-weight 428B multimodal model with a 1M context — strong reported coding (59.0 SWE-Bench Pro) at low entry pricing. They diverge most on price and context window — each quantified below from the models' real specs.

Who wins what

Long-horizon agentic software engineering

Kimi K2.7 Code

Moonshot AI's open-weight 1T-parameter MoE model (32B active) tuned for long-horizon agentic coding, always reasoning yet ~30% more token-efficient than K2.6 — and it is the newer of the two.

Token-efficient reasoning (~30% fewer than K2.6)

Kimi K2.7 Code

MiniMax M3 is comparatively weak here — price doubles to $0.60/$2.40 above 512K tokens — not flat across 1M

Open-weight 1T MoE, self-hostable

Kimi K2.7 Code

Kimi K2.7 Code lists open-weight 1T MoE, self-hostable among its strengths; MiniMax M3 does not.

Open-weight 428B MoE (~23B active per token) with a 1M-token context

MiniMax M3

Its 1M window holds about 4× more than Kimi K2.7 Code's 256K in a single prompt.

Native multimodal input — text, image and video

MiniMax M3

MiniMax's open-weight 428B multimodal model with a 1M context — strong reported coding (59.0 SWE-Bench Pro) at low entry pricing — and it runs cheaper at $0.3/$1.2 per 1M tokens.

Reports 59.0 on SWE-Bench Pro (a strong open-weight score), surpassing GPT-5.5

MiniMax M3

Kimi K2.7 Code is comparatively weak here — only self-reported benchmarks; no SWE-Bench Verified

Lowest cost at scale

MiniMax M3

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

MiniMax M3

Its 1M window is about 4× larger than Kimi K2.7 Code's 256K, fitting roughly 1,573 pages in one prompt.

Which should you pick?

A cost-sensitive startup shipping high volume

MiniMax M3

At $0.3/$1.2 per 1M tokens it undercuts Kimi K2.7 Code, and on millions of tokens that margin decides the monthly bill.

Someone analysing very long documents or codebases

MiniMax M3

Larger 1M window fits more in one prompt.

Anyone whose priority is long-horizon agentic software engineering

Kimi K2.7 Code

It is specifically built for that.

Anyone whose priority is open-weight 428b moe (~23b active per token) with a 1m-token context

MiniMax M3

That is its strongest area.

Kimi K2.7 Code: where it fits

Moonshot AI's open-weight 1T-parameter MoE model (32B active) tuned for long-horizon agentic coding, always reasoning yet ~30% more token-efficient than K2.6. Released June 12, 2026 by Moonshot AI, it is built for long-horizon agentic software engineering, token-efficient reasoning (~30% fewer than K2.6), open-weight 1T MoE, self-hostable, and multi-turn tool use with preserved reasoning.

Its trade-offs are real: only self-reported benchmarks; no SWE-Bench Verified, and thinking mode and sampling params can't be disabled. At $0.95 in / $4 out per million tokens, it sits in the budget price band.

MiniMax M3: where it fits

MiniMax's open-weight 428B multimodal model with a 1M context — strong reported coding (59.0 SWE-Bench Pro) at low entry pricing. Released June 2026 by MiniMax, it is built for open-weight 428B MoE (~23B active per token) with a 1M-token context, native multimodal input — text, image and video, reports 59.0 on SWE-Bench Pro (a strong open-weight score), surpassing GPT-5.5, and low entry pricing at $0.30/$1.20 per million up to 512K tokens.

Its trade-offs: price doubles to $0.60/$2.40 above 512K tokens — not flat across 1M, miniMax's own reported 80.5 SWE-Bench Verified figure is vendor-stated, not independently verified, sWE-Bench Pro is a different, harder benchmark than SWE-Bench Verified, and newer than M2.7 but with less independent testing so far. At $0.3 in / $1.2 out per million tokens, it sits in the budget price band.

The bottom line for this matchup

Kimi K2.7 Code and MiniMax M3 overlap enough that the right pick depends on your specific job. MiniMax M3 costs less per token; MiniMax M3 holds the larger context; and each leads in its own area — Kimi K2.7 Code for long-horizon agentic software engineering, MiniMax M3 for open-weight 428b moe (~23b active per token) with a 1m-token context. Rather than crowning one, run the same hard task through both once and let the results decide.

Frequently asked questions

Is Kimi K2.7 Code or MiniMax M3 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, Kimi K2.7 Code leans toward long-horizon agentic software engineering while MiniMax M3 leans toward open-weight 428b moe (~23b active per token) with a 1m-token context, and that positioning usually predicts which feels better on your codebase.

Which is cheaper, Kimi K2.7 Code or MiniMax M3?

MiniMax M3 is cheaper — $0.95/$4 per 1M tokens vs $0.3/$1.2 per 1M tokens, roughly 3.2× apart on input.

Which has the bigger context window?

MiniMax M3 — 1M vs 256K, about 4× larger. Useful only if the model actually reasons over the full window, which not all do.

Can I use both Kimi K2.7 Code and MiniMax M3 together?

Yes — a multi-model platform like LumiChats gives you Kimi K2.7 Code, MiniMax M3 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, Kimi K2.7 Code or MiniMax M3?

Kimi K2.7 Code — released June 12, 2026, about 11 days after MiniMax M3.
