Optimized Grok Code Fast 1 in Kilo Code

Grok Code Fast 1 is back — optimized with test-time compute scaling for faster, smarter coding. Free in Kilo Code for a limited time.

Why Optimized Grok Code Fast 1

Smarter when it needs to be. Faster when it needs to be.

Test-Time Compute Scaling

Dynamically allocates more or less compute per request. Simple tasks stay fast, complex reasoning gets the depth it needs.

Better Benchmarks

Tuned to outperform on the metrics that actually matter to developers — not just synthetic tests, but real developer workflows.

Real-World Speed

Calibrated for real coding tasks — the messy, complex, multi-file logic you deal with every day. Not just fast on benchmarks, fast where it counts.

Free for a Limited Time

Zero cost to start. Available free via Kilo Cloud — no BYOK setup, no API keys, no subscription required.

Lower Ongoing Costs

Even after the free period, Optimized Grok Code Fast 1 will remain affordable. High-performance coding at a fraction of comparable model costs.

Full Kilo Ecosystem

Use it everywhere — VS Code, JetBrains, CLI, Cloud Agents, and Kilo for Slack. One model, every workflow.

About the Optimization

This isn't vanilla Grok Code Fast 1. Built with an innovative American AI lab, this version uses test-time compute scaling — dynamically allocating compute per request so it's faster when speed matters and smarter when reasoning matters. Already a leader for coding and code reviews in Kilo, the optimization pushes it further with better benchmarks and real-world speed for actual coding tasks.
