GLM 4.7 vs Mistral Medium 3

Z.ai · China  |  Mistral AI · France · Updated June 2026

Quick verdict

Pick GLM 4.7 for genuinely permissive open weights — an mit-licensed 358b mixture-of-experts with no commercial restrictions or strong agentic coding for the price — 73.8% on swe-bench verified undercut most closed frontier models at launch. Pick Mistral Medium 3 for strong cost-to-capability at $0.40/$2.00 or general reasoning, coding and multimodal tasks. Choose GLM 4.7 if you need self-hosting or data privacy; Mistral Medium 3 if you want a managed API.

GLM 4.7 (Z.ai, China) and Mistral Medium 3 (Mistral AI, France) line up two different AI ecosystems against each other — a comparison that is as much about cost philosophy and openness as raw capability. GLM 4.7 is an MIT-licensed 358B open mixture-of-experts with strong 73.8% SWE-Bench Verified coding — but two generations behind GLM 5.2. Mistral Medium 3 is mistral's mid-tier model at $0.40/$2.00 — efficient general capability with a 128K window, below the 1M-context frontier tier. They diverge most on price, context window and open vs. closed weights — each quantified below from the models' real specs.

Who wins what

Genuinely permissive open weights — an MIT-licensed 358B mixture-of-experts with no commercial restrictions

GLM 4.7

Open weights make this possible at all — Mistral Medium 3 is API-only, so it cannot leave the vendor's servers.

Strong agentic coding for the price — 73.8% on SWE-Bench Verified undercut most closed frontier models at launch

GLM 4.7

Mistral Medium 3 is comparatively weak here — no published SWE-Bench Verified score

An unusually generous 128K maximum output, which suits bulk refactors and long generation

GLM 4.7

Its 200K window holds about 1.6× more than Mistral Medium 3's 128K in a single prompt.

Strong cost-to-capability at $0.40/$2.00

Mistral Medium 3

At $0.4/$2 per 1M tokens it undercuts GLM 4.7 ($0.6/$2.2 per 1M tokens), and that gap compounds at volume.

General reasoning, coding and multimodal tasks

Mistral Medium 3

Mistral's mid-tier model at $0.40/$2.00 — efficient general capability with a 128K window, below the 1M-context frontier tier — and it runs cheaper at $0.4/$2 per 1M tokens.

Efficient mid-tier deployment for production workloads

Mistral Medium 3

Mistral Medium 3 lists efficient mid-tier deployment for production workloads among its strengths; GLM 4.7 does not.

Lowest cost at scale

Mistral Medium 3

At $0.4/$2 per 1M tokens, it is the cheaper of the two — the gap dominates the bill on high-volume workloads.

Largest single-prompt input

GLM 4.7

Its 200K window is about 1.6× larger than Mistral Medium 3's 128K, fitting roughly 304 pages in one prompt.

Which should you pick?

A cost-sensitive startup shipping high volume

Mistral Medium 3

At $0.4/$2 per 1M tokens it undercuts GLM 4.7, and on millions of tokens that margin decides the monthly bill.

Someone analysing very long documents or codebases

GLM 4.7

Larger 200K window fits more in one prompt.

A team with data-privacy or self-hosting needs

GLM 4.7

Open weights let you run it on your own hardware; Mistral Medium 3 is API-only.

Anyone whose priority is genuinely permissive open weights — an mit-licensed 358b mixture-of-experts with no commercial restrictions

GLM 4.7

It is specifically built for that.

Anyone whose priority is strong cost-to-capability at $0.40/$2.00

Mistral Medium 3

That is its strongest area.

An enterprise with regional data-residency rules

GLM 4.7: where it fits

An MIT-licensed 358B open mixture-of-experts with strong 73.8% SWE-Bench Verified coding — but two generations behind GLM 5.2. Released December 22, 2025 by Z.ai, it is built for genuinely permissive open weights — an MIT-licensed 358B mixture-of-experts with no commercial restrictions, strong agentic coding for the price — 73.8% on SWE-Bench Verified undercut most closed frontier models at launch, an unusually generous 128K maximum output, which suits bulk refactors and long generation, and cheap long-running agent loops thanks to aggressive prompt caching.

Its trade-offs are real: two generations behind — GLM 5, 5.1 and 5.2 have all shipped since, and new builds should default to those, its Verified lead narrows sharply on harder evaluations like SWE-Bench Pro, and text-only with no vision, and self-hosting a 358B model is a serious hardware commitment. At $0.6 in / $2.2 out per million tokens, it sits in the budget price band.

Mistral Medium 3: where it fits

Mistral's mid-tier model at $0.40/$2.00 — efficient general capability with a 128K window, below the 1M-context frontier tier. Released May 7, 2025 by Mistral AI, it is built for strong cost-to-capability at $0.40/$2.00, general reasoning, coding and multimodal tasks, efficient mid-tier deployment for production workloads, and text and image input.

Its trade-offs: a 128K context — smaller than the 1M-window flagships here, no published SWE-Bench Verified score, a mid-tier model, not a frontier reasoner, and proprietary, unlike Mistral's open-weight releases. At $0.4 in / $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. GLM 4.7 gives you weights you control — self-host it, fine-tune it, keep data in-house, pay only for hardware. Mistral Medium 3 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 GLM 4.7 or Mistral Medium 3 better for coding?

Public SWE-Bench figures are not available for Mistral Medium 3, so the honest test is your own repository — run an identical real bug through both. By design, GLM 4.7 leans toward genuinely permissive open weights — an mit-licensed 358b mixture-of-experts with no commercial restrictions while Mistral Medium 3 leans toward strong cost-to-capability at $0.40/$2.00, and that positioning usually predicts which feels better on your codebase.

Which is cheaper, GLM 4.7 or Mistral Medium 3?

GLM 4.7 is open-weight, so self-hosting means no per-token fee (you pay for hardware instead), while Mistral Medium 3 is API-metered at $0.4/$2 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?

GLM 4.7 — 200K vs 128K, about 1.6× larger. Useful only if the model actually reasons over the full window, which not all do.

Can I use both GLM 4.7 and Mistral Medium 3 together?

Yes — a multi-model platform like LumiChats gives you GLM 4.7, Mistral Medium 3 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, GLM 4.7 or Mistral Medium 3?

GLM 4.7 — released December 22, 2025, about 8 months after Mistral Medium 3.
