Deep dive
The capability footprint differs most on function calling: Grok Build 0.1, tool use: Grok Build 0.1, and code execution: DeepSeek R1 0528. 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, DeepSeek R1 0528 lists $0.50/1M input and $2.15/1M 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 DeepSeek R1 0528 lower by about $0.30 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 2, so concentration risk also matters.
Choose DeepSeek R1 0528 when coding workflow support, lower input-token cost, and broader provider choice are central to the workload. Choose Grok Build 0.1 when coding workflow support and larger context windows 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, DeepSeek R1 0528 or Grok Build 0.1?
Grok Build 0.1 supports 256K 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, DeepSeek R1 0528 or Grok Build 0.1?
DeepSeek R1 0528 lists $0.50/1M input and $2.15/1M 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.
Is DeepSeek R1 0528 or Grok Build 0.1 open source?
DeepSeek R1 0528 is listed under Open Source. Grok Build 0.1 is listed under Proprietary. License labels affect whether you can self-host, redistribute weights, or rely only on hosted APIs, so confirm the upstream license before deployment.
Which is better for reasoning mode, DeepSeek R1 0528 or Grok Build 0.1?
Both DeepSeek R1 0528 and Grok Build 0.1 expose reasoning mode. The better choice depends on benchmark fit, context budget, pricing, and whether your provider route exposes the same capability surface.
Which is better for function calling, DeepSeek R1 0528 or Grok Build 0.1?
Grok Build 0.1 has the clearer documented function calling signal in this comparison. If function calling is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
Where can I run DeepSeek R1 0528 and Grok Build 0.1?
DeepSeek R1 0528 is available on Together AI, Fireworks AI, GCP Vertex AI, Novita AI, and OpenRouter. Grok Build 0.1 is available on xAI Console and Vercel AI Gateway. Provider coverage can affect latency, region availability, compliance posture, and fallback options.
