Grok 4.6
xAI's frontier model for coding and agentic work, paired with Grok Build — their own open-source coding agent and terminal UI.
Grok 4.6 is xAI’s frontier model for coding, agentic tasks, and knowledge work, and the current flagship behind Grok Build — xAI’s dedicated coding agent and terminal UI.
Why it stands out
- Aggressive tiered pricing — a lower rate below 200K prompt tokens and a scaled-up rate above it, so short-context coding sessions stay cheap.
- Grok Build, xAI’s open-source coding agent and TUI, gives it a purpose-built harness rather than relying only on third-party tools.
- 500K-token context window, comfortably large for most real-world coding sessions.
Good for
Fast, iterative agentic coding workflows — especially teams already using Grok Build or wanting a cheaper alternative to the largest frontier models for everyday agent loops.
