Deep dive
On shared benchmark coverage, Massive Multitask Language Understanding has Llama 2 70B Chat at 68.9 and Mistral 7B Instruct v0.3 at 78.9, with Mistral 7B Instruct v0.3 ahead by 10 points. The largest visible gap is 10 points on Massive Multitask Language Understanding, 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: Mistral 7B Instruct v0.3 and structured outputs: Llama 2 70B Chat. Both models share the core language-model surface, 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 2 70B Chat lists $0.5/1M input and $1.5/1M output tokens, while Mistral 7B Instruct v0.3 lists $0.2/1M input and $0.2/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Mistral 7B Instruct v0.3 lower by about $0.6 per million blended tokens. Availability is 14 providers versus 2, so concentration risk also matters.
Choose Llama 2 70B Chat when provider fit and broader provider choice are central to the workload. Choose Mistral 7B Instruct v0.3 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.
