Grok Build 0.1 is SpaceXAI’s fast coding model trained specifically for agentic software engineering workflows.
Key facts
- Input price
- $1.00 / 1M tokens
- Output price
- $2.00 / 1M tokens
- Context window
- 256K tokens
- Max output
- 230K tokens
- Accepts
- Text, Images, Files
- Returns
- Text
Example: 1,000 requests with 1,000 input and 500 output tokens each would cost about $2.00 (1M input tokens × $1.00 + 0.5M output tokens × $2.00). Estimate your own usage.
Prices are the provider’s own per-token rates with zero markup, from our price list as of Oct 18, 2026. If a call has extra provider charges (images, audio, web search, cached prompts), you pay the reported cost.
