Which should you choose?
Which is better: GPT-4.1 mini, GLM-4.5V or Mistral Medium 3?
GPT-4.1 mini is the better all-round choice, scoring 62/100 against GLM-4.5V (49) and Mistral Medium 3 (47). It leads on price and context window. 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, GPT-4.1 mini, GLM-4.5V or Mistral Medium 3?
GPT-4.1 mini is cheaper at $0.40 input / $1.60 output per million tokens (official OpenAI API price). Mistral Medium 3 costs $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). At a typical mix of three input tokens to one output token, that is $0.70 per million tokens for GPT-4.1 mini versus $0.80 for Mistral Medium 3 (1.1× as much) and $0.90 for GLM-4.5V (1.3× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. GPT-4.1 mini has an ECI of 135.0, GLM-4.5V has not been scored yet and Mistral Medium 3 has an ECI of 134.1.
Which is better for coding?
There are no published SWE-bench Verified results for GPT-4.1 mini, GLM-4.5V and Mistral Medium 3 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?

GLM-4.5V publishes its weights and can be self-hosted; GPT-4.1 mini and Mistral Medium 3 is proprietary.
Which is newer?
GLM-4.5V is the newest, released Aug 11, 2025. Mistral Medium 3 came out May 7, 2025; GPT-4.1 mini came out Apr 14, 2025. Knowledge cutoff: GPT-4.1 mini Apr 2024, GLM-4.5V Apr 2025, Mistral Medium 3 May 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.
