Code Cushman 001 vs Grok Build 0.1
Code Cushman 001 (2021) and Grok Build 0.1 (2026) are agentic coding models from OpenAI and xAI. Code Cushman 001 ships a not-yet-sourced context window, while Grok Build 0.1 ships a 256k-token context window. This comparison covers specs, pricing, capabilities, benchmarks, provider availability, and production fit. It focuses on practical selection signals rather than broad model-family marketing. The goal is to make the tradeoff clear before deeper testing.
Grok Build 0.1 is safer overall; choose Code Cushman 001 when coding workflow support matters.

Deep dive
The capability footprint differs most on reasoning mode: Grok Build 0.1, function calling: Grok Build 0.1, tool use: Grok Build 0.1, and structured outputs: Grok Build 0.1. 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.
Pricing coverage is uneven: Code Cushman 001 has no token price sourced yet and Grok Build 0.1 has $1/1M input tokens. Provider availability is 0 tracked routes versus 3. Treat unknown pricing as an integration gap, then verify the route you will actually call before estimating production spend.
Choose Code Cushman 001 when coding workflow support are central to the workload. Choose Grok Build 0.1 when coding workflow support and broader provider choice 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. It also helps separate model capability from provider packaging, which can change cost and latency.
FAQ
Is Code Cushman 001 or Grok Build 0.1 open source?
Code Cushman 001 is listed under Proprietary. 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, Code Cushman 001 or Grok Build 0.1?
Grok Build 0.1 has the clearer documented reasoning mode signal in this comparison. If reasoning mode is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
Which is better for function calling, Code Cushman 001 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.
Which is better for tool use, Code Cushman 001 or Grok Build 0.1?
Grok Build 0.1 has the clearer documented tool use signal in this comparison. If tool use is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
Which is better for structured outputs, Code Cushman 001 or Grok Build 0.1?
Grok Build 0.1 has the clearer documented structured outputs signal in this comparison. If structured outputs is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
Where can I run Code Cushman 001 and Grok Build 0.1?
Code Cushman 001 is available on the tracked providers still being sourced. Grok Build 0.1 is available on xAI Console, Vercel AI Gateway, and OpenRouter. Provider coverage can affect latency, region availability, compliance posture, and fallback options.
