Frequently Asked Questions
- What is Grok Build used for?
- Grok Build is used for code, vision and multimodal work, and reasoning. The family description and listed model capabilities point to those workloads as the best fit.
- How does Grok Build compare to Grok 1?
- Grok Build by xAI is strongest where you need code, while Grok 1 by xAI is the closest related family to check for reasoning. Grok Build has 1 listed variant and reaches up to 256k context, so compare the specs and pricing tables before choosing a production model.
- Which Grok Build model should I use?
- If price is the main constraint, use the pricing table first because Grok Build does not have complete provider pricing in the local data. For the most capable/latest local choice, evaluate Grok Build 0.1 with 256k context and reasoning, tool use, function calling, structured outputs, and multimodal inputs.
