01 — Verdict

Too close to call

It is close. Our weighted score puts them within a point (Mistral Medium 3.1 50/100, GLM-4.5V 49/100, GLM-4.6 42/100), so choose by what matters most for your work: Mistral Medium 3.1 on price and Mistral Medium 3.1 for long inputs. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.

04 — Questions

Which should you choose?

Which is better: Mistral Medium 3.1, GLM-4.6 or GLM-4.5V?

It is close. Our weighted score puts them within a point (Mistral Medium 3.1 50/100, GLM-4.5V 49/100, GLM-4.6 42/100), so choose by what matters most for your work: Mistral Medium 3.1 on price and Mistral Medium 3.1 for long inputs. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.

Which is cheaper, Mistral Medium 3.1, GLM-4.6 or GLM-4.5V?

Mistral Medium 3.1 is cheaper at $0.40 input / $2.00 output per million tokens (official Mistral API price). GLM-4.5V costs $0.60 input / $1.80 output per million tokens (official Z.AI API price); GLM-4.6 costs $0.60 input / $2.20 output per million tokens (official Z.AI API price). At a typical mix of three input tokens to one output token, that is $0.80 per million tokens for Mistral Medium 3.1 versus $0.90 for GLM-4.5V (1.1× as much) and $1.00 for GLM-4.6 (1.3× as much).

Which scores higher on benchmarks?

There is no independent benchmark that covers all three models yet. Mistral Medium 3.1 has not been scored yet, GLM-4.6 has not been scored yet and GLM-4.5V has not been scored yet.

Which is better for coding?

There are no published SWE-bench Verified results for Mistral Medium 3.1, GLM-4.6 and GLM-4.5V yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. All three support tool calling for agent workflows.

Which has the bigger context window?

Mistral Medium 3.1 has the largest context window at 262,144 tokens, against 204,800 for GLM-4.6 and 64,000 for GLM-4.5V. Maximum output per response: Mistral Medium 3.1 up to 262,144, GLM-4.6 up to 131,072, GLM-4.5V up to 16,384 tokens.

Which can read images, PDFs, audio or video?

Mistral Medium 3.1 accepts text and images; GLM-4.6 accepts text; GLM-4.5V accepts text, images and video. GLM-4.5V handles the widest range of inputs.

Are any of these open source?

GLM-4.6 and GLM-4.5V publishes its weights and can be self-hosted; Mistral Medium 3.1 is proprietary.

Which is newer?

GLM-4.6 is the newest, released Sep 30, 2025. Mistral Medium 3.1 came out Aug 12, 2025; GLM-4.5V came out Aug 11, 2025. Knowledge cutoff: Mistral Medium 3.1 May 2025, GLM-4.6 Apr 2025, GLM-4.5V Apr 2025.

How do you decide the winner?

Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Oct 4, 2026.
