Deep dive

On shared benchmark coverage, MMLU PRO has Claude 3.7 Sonnet at 80.3 and DeepSeek R1 0528 at 85, with DeepSeek R1 0528 ahead by 4.7 points; SWE-bench Verified has Claude 3.7 Sonnet at 70.3 and DeepSeek R1 0528 at 57.6, with Claude 3.7 Sonnet ahead by 12.7 points; LiveCodeBench has Claude 3.7 Sonnet at 68.9 and DeepSeek R1 0528 at 73.3, with DeepSeek R1 0528 ahead by 4.4 points. The largest visible gap is 12.7 points on SWE-bench Verified, 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 vision: Claude 3.7 Sonnet, multimodal input: Claude 3.7 Sonnet, function calling: Claude 3.7 Sonnet, and tool use: Claude 3.7 Sonnet. Both models share reasoning mode, structured outputs, and code execution, 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 3.7 Sonnet lists $3/1M input and $15/1M output tokens on the cheapest tracked provider, while DeepSeek R1 0528 lists $0.50/1M input and $2.15/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts DeepSeek R1 0528 lower by about $5.60 per million blended tokens. Availability is 6 providers versus 6, so concentration risk also matters.

Choose Claude 3.7 Sonnet when coding workflow support and larger context windows are central to the workload. Choose DeepSeek R1 0528 when coding workflow support 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.

FAQ

Which has a larger context window, Claude 3.7 Sonnet or DeepSeek R1 0528?

Claude 3.7 Sonnet supports 200k tokens, while DeepSeek R1 0528 supports 130k tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.

Which is cheaper, Claude 3.7 Sonnet or DeepSeek R1 0528?

DeepSeek R1 0528 is cheaper on tracked token pricing. Claude 3.7 Sonnet costs $3/1M input and $15/1M output tokens. DeepSeek R1 0528 costs $0.50/1M input and $2.15/1M output tokens. Provider discounts or batch pricing can still change the final bill.

Is Claude 3.7 Sonnet or DeepSeek R1 0528 open source?

Claude 3.7 Sonnet is listed under Proprietary. DeepSeek R1 0528 is listed under MIT. License labels affect whether you can self-host, redistribute weights, or rely only on hosted APIs, so confirm the upstream license before deployment.
