04 — Questions

Which should you choose?

Which is better: Mistral Large 2407, Llama-3.1-70B-Instruct or GPT-4o?

It is close. Our weighted score puts them within a point (Llama-3.1-70B-Instruct 43/100, GPT-4o 43/100, Mistral Large 2407 39/100), so choose by what matters most for your work: GPT-4o for raw capability, Llama-3.1-70B-Instruct 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, Mistral Large 2407, Llama-3.1-70B-Instruct or GPT-4o?

Llama-3.1-70B-Instruct is cheaper at $0.72 input / $0.72 output per million tokens (median across 8 API providers). 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 $0.72 per million tokens for Llama-3.1-70B-Instruct versus $3.00 for Mistral Large 2407 (4.2× as much) and $4.38 for GPT-4o (6.1× 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 Llama-3.1-70B-Instruct 125.9 (#149 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%, Llama-3.1-70B-Instruct 44.2%; OTIS Mock AIME 2024–2025 — Mistral Large 2407 8.5%, GPT-4o 6.3%, Llama-3.1-70B-Instruct 3.6%.

Which is better for coding?

There are no published SWE-bench Verified results for Mistral Large 2407, Llama-3.1-70B-Instruct and GPT-4o 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 Llama-3.1-70B-Instruct and 128,000 for GPT-4o. Maximum output per response: Mistral Large 2407 up to 104,857, Llama-3.1-70B-Instruct up to 4,096, GPT-4o up to 16,384 tokens.

Which can read images, PDFs, audio or video?

Mistral Large 2407 accepts text and PDFs; Llama-3.1-70B-Instruct accepts text; GPT-4o accepts text, images and PDFs. GPT-4o handles the widest range of inputs.

Are any of these open source?

Mistral Large 2407 and Llama-3.1-70B-Instruct publishes its weights and can be self-hosted; GPT-4o is proprietary.

Which is newer?

Mistral Large 2407 is the newest, released Jul 24, 2024. Llama-3.1-70B-Instruct came out Jul 23, 2024; GPT-4o came out May 13, 2024. Knowledge cutoff: Mistral Large 2407 Mar 31, 2024, Llama-3.1-70B-Instruct Dec 2023, GPT-4o Sep 2023.

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.
