Get Unlimited Free AI Coding with Grok Code Fast 1 in VS Code

Revolutionary Free AI Coding Power Lands in Your IDE

Imagine having access to one of 2025’s most advanced AI coding models completely free, with no usage limits, directly inside Visual Studio Code. That’s exactly what happened when xAI’s breakthrough Grok Code Fast 1 model became available through the Kilo Code extension.

This isn’t just another coding assistant launch. Grok Code Fast 1 represents a significant leap in AI coding capabilities, offering a massive 256,000-token context window at pricing that makes it incredibly accessible. Through an exclusive partnership with Kilo Code, developers can access this frontier model without paying a single rupee for at least a week, with no rate limits or throttling.

What Makes Grok Code Fast 1 Different from Other AI Models

Grok Code Fast 1 launched in late August 2025 as xAI’s specialized coding model, designed specifically for “agentic coding” workflows. Unlike general-purpose AI models that were adapted for coding, this model was built from the ground up for software development tasks.

Core Technical Specifications:

• Context Window: 256,000 tokens (combined input/output)
• Architecture: 314 billion parameters with Mixture of Experts (MoE)
• Speed: 92 tokens per second throughput
• Pricing: $0.20 (₹16.7) per 1M input tokens, $1.50 (₹125) per 1M output tokens

The model excels at several key areas that set it apart from competitors. Its reasoning capabilities are visible in responses, allowing developers to understand exactly how the AI arrives at its solutions. This transparency proves invaluable when debugging complex code or understanding suggested improvements.

What’s particularly impressive is the model’s ability to handle large codebases without losing context. The 256K token window means it can analyze entire software repositories, understand architectural patterns, and suggest changes that maintain consistency across thousands of lines of code.
