Should you use it?

Grok Code Fast 1 was xAI's speed-oriented coding model and retired on May 15, 2026. xAI's migration docs no longer support it as a standalone buy path and now need redirect-target confirmation, while GitHub Copilot removed it from chat, completions, edits, ask, and agent modes, with GPT-5 mini and Claude Haiku 4.5 as in-product alternatives. Treat this page as a migration reference rather than a buy recommendation.

Full review notes Long-form details, FAQ, and source history

Grok Code Fast 1 is xAI’s coding-focused model for developer workflows. It launched in late August 2025 and was positioned as a “speedy and economical reasoning model that excels at agentic coding.” It was retired on May 15, 2026, so this page is now a migration reference rather than a buying option.

Retirement status (retired May 15, 2026)

  • xAI API retirement and redirect. xAI’s May 15 retirement docs retired grok-code-fast-1 on May 15, 2026 at 12:00pm PT. As of the June 27 check, the same xAI migration page contains conflicting redirect-target language, so treat any surviving old-slug behavior as a replacement-model migration that needs live confirmation.
  • GitHub Copilot retirement. On May 8, 2026 GitHub announced that Grok Code Fast 1 would be deprecated across all Copilot experiences on May 15, 2026; that removal is now in effect. It covered Copilot Chat, inline edits, ask and agent modes, and code completions. GitHub lists GPT-5 mini and Claude Haiku 4.5 as suggested alternatives and tied the accelerated timing to the upstream xAI provider deprecation.
  • No original-model grandfathering. Neither xAI nor GitHub published a continued-availability window for the original model beyond May 15, 2026. Redirect behavior still needs replacement-model pricing and quality checks.

Recent developments
  • June 27, 2026: Post-retirement recheck confirms grok-code-fast-1 is no longer a standalone buy path. xAI’s migration doc now contains conflicting redirect-target language, and GitHub Copilot’s May 15 changelog confirms Copilot-wide deprecation.
  • June 23, 2026: Post-retirement check confirmed grok-code-fast-1 was no longer a standalone buy path.
  • June 12, 2026: Post-retirement check confirmed grok-code-fast-1 was gone from GitHub Copilot. Any remaining references should be treated as migration cleanup.
  • May 15, 2026: Retirement cutoff. The model left the xAI API and all GitHub Copilot surfaces.
  • May 8, 2026: GitHub announced the Copilot-wide retirement, referencing the upstream xAI provider deprecation.

System Verdict

Evaluate the actual replacement model or another current xAI coding route for new xAI coding work. xAI’s migration docs no longer make grok-code-fast-1 a forward-looking standalone model choice, and the current redirect-target language needs confirmation before you standardize.

If you still reference Grok Code Fast 1, migrate deliberately. xAI API calls may redirect rather than fail, which can hide a model swap in billing and evaluation. Move Copilot-managed workflows to GPT-5 mini, Claude Haiku 4.5, Sonnet 4.6, or GPT-5.5.

Drop agentic-coding contracts pinned to Grok Code Fast 1. Any spec, RFP, or evaluation that still names the model should be updated; the May 15, 2026 retirement was a hard cutoff per xAI’s published docs.

Pricing

Grok Code Fast 1 no longer has a current standalone price. The last published xAI API rates before retirement were $0.20 per million input tokens, $1.50 per million output tokens, and $0.02 per million cached input tokens.

Do not use those rates for new procurement. xAI no longer sells grok-code-fast-1 as a standalone model after May 15, 2026, so buyers need to price and evaluate the replacement model actually serving the workload.

Migration plan

The May 15, 2026 cutoff has passed, so any workload still pinned to Grok Code Fast 1 is already broken. The migration steps are:

  • Inventory direct xAI API usage. Identify every service, agent loop, or batch job that still calls grok-code-fast-1. Confirm the actual replacement model in live API behavior or logs, then decide whether that model fits latency and cost targets.
  • Inventory GitHub Copilot usage. Confirm whether developers still select Grok Code Fast 1 in Copilot Chat, inline edits, ask, agent, or completion modes. Point them to the GitHub-recommended alternatives (GPT-5 mini, Claude Haiku 4.5).
  • Re-benchmark before standardizing on the redirect. xAI does not guarantee that price-per-accepted-patch or merge quality will match Grok Code Fast 1. Run your existing test-fix loop and accepted-edit benchmarks against the confirmed replacement before committing.
  • Audit Copilot Enterprise model policies. If a Copilot administrator left the recommended alternatives disabled, developers selecting Grok Code Fast 1 now hit broken workflows. Update model allowlists to GPT-5 mini, Claude Haiku 4.5, or another supported model.
  • Update reviewer and procurement docs. RFPs, evaluation spreadsheets, and internal guides should drop Grok Code Fast 1 as a forward-looking choice.

Failure modes
  • Hard retirement cutoff with redirect risk. xAI’s docs name May 15, 2026 with no public extension for the original model. Workloads still pinned to the slug can silently become replacement-model workloads.
  • Ecosystem churn risk. Copilot’s model picker is convenient, but the Grok Code Fast 1 removal shows that third-party model access there depends on upstream provider roadmaps.
  • The replacement is a different model. Treat the xAI redirect as a new evaluation rather than a drop-in upgrade. Benchmark merge rate, reviewer rework, failed tool calls, and rollback rate before standardizing.
  • No long-term coding contract here. A model on a public 2026 retirement path is not a stable foundation for multi-year coding-stack decisions.
