Grok 4.5

A frontier reasoning model for coding, knowledge work, and STEM tasks. It supports image input, function calling, and structured outputs; its 500K-token context suits cross-file analysis and long source material. Prefer a lower-cost model when frontier reasoning is unnecessary.

  • Reasoning
  • Function calling
  • Structured output
  • Long context
