Which should you choose?
Which is better: GPT-4o, Mistral Large or Mistral Large 2407?
It is close. Our weighted score puts them within a point (Mistral Large 44/100, GPT-4o 43/100, Mistral Large 2407 39/100), so choose by what matters most for your work: GPT-4o for raw capability, Mistral Large on price and Mistral Large 2407 for long inputs. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%.
Which is cheaper, GPT-4o, Mistral Large or Mistral Large 2407?
Mistral Large is cheaper at $0.50 input / $1.50 output per million tokens (official Mistral API price). Mistral Large 2407 costs $2.00 input / $6.00 output per million tokens (median across 5 API providers); GPT-4o costs $2.50 input / $10.00 output per million tokens (official OpenAI API price). At a typical mix of three input tokens to one output token, that is $0.75 per million tokens for Mistral Large versus $3.00 for Mistral Large 2407 (4× as much) and $4.38 for GPT-4o (5.8× as much).
Which scores higher on benchmarks?
GPT-4o scores higher on the Capabilities Index (ECI): GPT-4o 129.0 (#141 of 165), Mistral Large 2407 127.6 (#144 of 165) and Mistral Large 122.0 (#153 of 165). The confidence ranges of the top two overlap (124.7–131.3 vs 123.3–129.4), so treat the gap as small. On individual benchmarks: GPQA Diamond — Mistral Large 2407 49.0%, GPT-4o 48.9%, Mistral Large 38.8%; OTIS Mock AIME 2024–2025 — Mistral Large 2407 8.5%, GPT-4o 6.3%, Mistral Large 1.9%.
Which is better for coding?
There are no published SWE-bench Verified results for GPT-4o, Mistral Large and Mistral Large 2407 yet, so there is no like-for-like coding score. On overall capability, GPT-4o leads, which tends to carry over to coding, but test on your own codebase. All three support tool calling for agent workflows.
Which has the bigger context window?
Mistral Large 2407 has the largest context window at 131,072 tokens, against 128,000 for GPT-4o and 128,000 for Mistral Large. Maximum output per response: GPT-4o up to 16,384, Mistral Large up to 102,400, Mistral Large 2407 up to 104,857 tokens.

Are any of these open source?
Mistral Large 2407 publishes its weights and can be self-hosted; GPT-4o and Mistral Large is proprietary.
Which is newer?
Mistral Large 2407 is the newest, released Jul 24, 2024. GPT-4o came out May 13, 2024; Mistral Large came out Feb 26, 2024. Knowledge cutoff: GPT-4o Sep 2023, Mistral Large Nov 30, 2024, Mistral Large 2407 Mar 31, 2024.
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 Nov 2, 2026.
