Deep dive
The capability footprint differs most on reasoning mode: DeepSeek R1 Distill Llama 70B and structured outputs: DeepSeek R1 Distill Llama 70B. 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, DeepSeek R1 Distill Llama 70B lists $0.35/1M input and $1.05/1M output tokens, while Mistral Magistral Small 2509 lists $0.5/1M input and $1.5/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts DeepSeek R1 Distill Llama 70B lower by about $0.24 per million blended tokens. Availability is 4 providers versus 1, so concentration risk also matters.
Choose DeepSeek R1 Distill Llama 70B when reasoning depth, lower input-token cost, and broader provider choice are central to the workload. Choose Mistral Magistral Small 2509 when provider fit are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship. This keeps the decision grounded in measurable tradeoffs instead of brand-level assumptions.
