xAI Launches Grok-Build-0.1 Code Model With 256K Context Window

xAI launched grok-build-0.1 for agentic coding and also integrated Grok with OpenCode, expanding developer access to multimodal, tool-enabled AI coding workflows with token-based API pricing.

Summary

xAI has introduced grok-build-0.1, an early-access code model for agentic coding, and separately integrated Grok with OpenCode to simplify developer access to AI coding tools. According to the provided information, grok-build-0.1 includes a 256K context window and supports text and image inputs, tool calling, structured output, and reasoning. API pricing starts at $1 per 1 million input tokens and $2 per 1 million output tokens. The OpenCode integration is described as potentially improving productivity and lowering costs for developers using that workflow.

Terms & Concepts
  • Context window: The amount of text or data a model can process at once. A 256K context window enables longer code files and instructions to be handled in one prompt.
  • Tool calling: A capability that lets an AI model invoke external software functions or services to complete tasks beyond text generation.
  • Integration: A technical connection between products or services that allows them to work together within a shared workflow.
