Builders · Model Families · ~16 min read
A coding model with attitude
Grok-Code is xAI's specialist fine-tune aimed at developer workflows. Reported SWE-bench scores land in the top tier, and the pricing is aggressive — roughly half of Sonnet for comparable coding tasks.
What it does well
- Multi-file edits with explicit diffs
- Refactors that touch imports and types coherently
- Shell + test-runner tool use
- Explaining legacy code in plain English
Compare the options
| Tool | Grok-Code | Claude Sonnet 4.6 | GPT-5.5 |
|---|---|---|---|
| SWE-bench (reported) | High | High | High |
| Price per M output | $ | $$ | $$$ |
| IDE integrations | Growing | Mature (Claude Code) | Mature (Codex) |
| Refusal tendency | Low | Medium | Medium |
OpenAI-compatible — drop into any existing Codex-style harness.
