GPT-4.1 mini vs Qwen3-Coder 30B-A3B Instruct vs Mistral Medium 3

GPT-4.1 mini is the better all-round choice, scoring 62/100 against Mistral Medium 3 (47) and Qwen3-Coder 30B-A3B Instruct (41). It leads on price, inputs & features 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.

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); Qwen3-Coder 30B-A3B Instruct costs $0.45 input / $2.25 output per million tokens (official Alibaba 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 Qwen3-Coder 30B-A3B Instruct (1.3× as much).

There is no independent benchmark that covers all three models yet. GPT-4.1 mini has an ECI of 135.0, Qwen3-Coder 30B-A3B Instruct has not been scored yet and Mistral Medium 3 has an ECI of 134.1.

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.
