xAI launches Grok Code Fast 1, a “speedy and economical” agentic coding model, available for free for a limited time on GitHub Copilot, Cursor, Windsurf, more
Elon Musk's artificial intelligence startup, xAI, on Thursday released a new “speedy and economical” agentic coding model …

Context & Ripple Effects
xAI had already emphasized faster delivery and lower API pricing in its Grok-2 rollout, then introduced a higher-performance multi-agent Grok 4 Heavy tier. Grok Code Fast 1 applies the speed-and-cost positioning specifically to agentic software development.
Making the model temporarily free across Copilot, Cursor, Windsurf and other coding environments matters because model distribution is shifting from standalone access to the developer work surfaces where agents execute tasks.
First-order effects
Developers using the listed coding platforms can test xAI's coding agent without an immediate model-access charge during the limited free period.
xAI gains a distribution channel inside established AI coding tools, while those tools can offer users another model option without building it themselves.
Second-order effects
Competing coding-model providers and tool vendors face added pressure to differentiate on coding quality, latency, pricing, and the reliability of agentic workflows rather than model availability alone.
A free launch can accelerate hands-on evaluation by engineering teams, making platform integrations and switching friction more important to retaining usage once promotional access ends.
Third-order effects
If providers continue shipping models through multiple coding environments, AI coding products may become increasingly modular: work surfaces compete for developer workflow ownership while models compete for default placement and economics.
The longer-term value may move toward agent orchestration, developer-context handling, and workflow integration; that outcome depends on whether users see durable performance differences among interchangeable models.
The trend: Agentic coding is becoming a distribution and workflow-integration contest as much as a frontier-model performance contest.
Grok code Fast 1 Just Dropped! It scores 70.8% on the SWE Verified benchmark. That puts it just under Claude Opus 4 non reasoning. Above GPT 5 non reasoning by quite a bit and below GPT 5 high thinking! [image]
Grok-code-fast-1 is now out and available for everyone to use 🚀🏎️💨 When I joined the coding team, the team was just 3 people and we very quickly built a model which was SOTA on SWEBench. But as things go, in the real world benchmarks matter less. Over the last few months we
🚀 Grok Code is LIVE! 🎉 Just months ago, I initiated this effort from scratch with the epic @MohitReddy13, typing our first line of code, and now it's finally out and FREE for 7 days — open your IDE in and try it! 👨💻 https://x.ai/... #GrokCode some fun stories behind👇
The model is generally available via the xAI API, priced at $0.20 / 1M input tokens, $1.50 / 1M output tokens, and $0.02 / 1M cached tokens. https://console.x.ai/
Been training the Grok Code Fast 1 model with the incredible team. It's a blazing fast model 🚀 that can solve a broad range of real-world agentic coding tasks. Excited to share it with the world, hope it help with your work!
We are thrilled to announce the release of our 1st model for coding and agentic tasks, grok-code-fast! You can now integrate it into all IDE and CLI tools for your daily coding needs. It's fast, powerful, and affordable! We're committed to continuous improvement based on your
This has been fun to work on! What began as a two-person effort months ago is now a small, talent-dense team striving to improve and ship new model versions. We've had great support from @Yuhu_ai_, @jimmybajimmyba, and @elonmusk, with exciting updates coming soon! I believe we
xAI's “grok-code-fast-1” is now widely accessible, priced at: - $0.20 per million input tokens - $1.50 per million output tokens - $0.02 per million cached input tokens [image]
It's been a great pleasure contributing to grok-code-fast-1 as part of this amazing team. It's a super fast yet super capable agentic model for your daily coding needs. Try it out in your favorite IDEs and let us know what to improve on!
The start of a new model line - Grok Code series. This time we focus on speed. It's a very new experience when the model is super fast. Try it out, it's free for 7 days on the major platforms.
Introducing Grok Code Fast 1, a speedy and economical reasoning model that excels at agentic coding. Now available for free on GitHub Copilot, Cursor, Cline, Kilo Code, Roo Code, opencode, and Windsurf. https://x.ai/...
