Pros

Plan mode blocks every edit until you approve the plan; approved changes show as clean diffs
Subagents run in parallel with their own context, with worktree support; workflows can fan a task out across many agents
Open source (Apache 2.0); AGENTS.md, MCP servers, hooks and custom models configured in config.toml

Cons

Launched as an early beta in May 2026, so it is younger than Claude Code or Codex
Full use needs an xAI account plan (Free is limited) or an xAI API key
