Deep dive
On shared benchmark coverage, SWE-bench Verified has Claude 3.7 Sonnet at 70.3 and Grok Build 0.1 at 70.8, with Grok Build 0.1 ahead by 0.5 points. The largest visible gap is 0.5 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 code execution: Claude 3.7 Sonnet. Both models share vision, multimodal input, reasoning mode, and function calling, 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 Grok Build 0.1 lists tiered pricing: 0-200,001t is $1/1M input and $2/1M output; 200,001t+ is $2/1M input and $4/1M output. A 70/30 input-output blend puts Grok Build 0.1 lower by about $5.30 per million blended tokens. For tiered rows, this cheapest-track view can understate interactive or fast-lane spend, so compare the tier you will actually use. Availability is 6 providers versus 3, so concentration risk also matters.
Choose Claude 3.7 Sonnet when coding workflow support and broader provider choice are central to the workload. Choose Grok Build 0.1 when coding workflow support, larger context windows, and lower cheapest-tier 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 Grok Build 0.1?
Grok Build 0.1 supports 256k tokens, while Claude 3.7 Sonnet supports 200k 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 Grok Build 0.1?
Claude 3.7 Sonnet lists $3/1M input and $15/1M output tokens on the cheapest tracked provider. Grok Build 0.1 lists tiered pricing: 0-200,001t is $1/1M input and $2/1M output; 200,001t+ is $2/1M input and $4/1M output. Compare the tier you will actually use; cheap async pricing can overstate savings for interactive workflows. Provider discounts or batch pricing can still change the final bill.
