Deep dive

On shared benchmark coverage, MMLU PRO has Llama 3.3 70B at 71.3 and Mistral Large 3 675B Instruct at 85.5, with Mistral Large 3 675B Instruct ahead by 14.2 points. The largest visible gap is 14.2 points on MMLU PRO, which matters most when that benchmark mirrors your workload. Treat isolated benchmark wins as directional, because provider routing, prompt style, and tool access can move real application results.

The capability footprint differs most on function calling: Llama 3.3 70B, tool use: Llama 3.3 70B, and structured outputs: Mistral Large 3 675B Instruct. Both models share vision and multimodal input, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.

For cost, Llama 3.3 70B lists $0.90/1M input and $0.90/1M output tokens on the cheapest tracked provider, while Mistral Large 3 675B Instruct lists $0.50/1M input and $1.50/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Mistral Large 3 675B Instruct lower by about $0.10 per million blended tokens. Availability is 1 providers versus 6, so concentration risk also matters.

Choose Llama 3.3 70B when vision-heavy evaluation are central to the workload. Choose Mistral Large 3 675B Instruct when long-context analysis, larger context windows, and lower input-token cost are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
