Deep dive
The capability footprint differs most on vision: Claude Opus 4.5, multimodal input: Claude Opus 4.5, function calling: Claude Opus 4.5, tool use: Claude Opus 4.5, and code execution: Claude Opus 4.5. Both models share reasoning mode and structured outputs, 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, Claude Opus 4.5 lists $5/1M input and $25/1M output tokens on the cheapest tracked provider, while DeepSeek R1 Distill Llama 70B lists $0.35/1M input and $1.05/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts DeepSeek R1 Distill Llama 70B lower by about $10.44 per million blended tokens. Availability is 6 providers versus 5, so concentration risk also matters.
Choose Claude Opus 4.5 when coding workflow support, larger context windows, and broader provider choice are central to the workload. Choose DeepSeek R1 Distill Llama 70B when provider fit 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.
