The artificial intelligence firm xAI has just unveiled its latest AI model — grok-code-fast-1 — marking its entrance into the agentic coding sector. The company describes this model as a “speedy daily driver” aimed at developers who find other robust models “frustratingly slow” for everyday tasks. According to xAI, this model is more than 60% (160 TPS) quicker than its nearest rivals: Gemini 2.5 Pro (92.39 TPS) and Qwen3-Coder (80 TPS).
Economical Pricing Structure
In addition to its speed, the company is marketing it as a cost-effective option, with a pricing set at $0.20 per million input tokens and $1.50 per million output tokens. As mentioned in their announcement, the model is adaptable across the entire software stack and demonstrates particular strength with programming languages such as TypeScript, Python, Java, and Rust.
Performance Insights
Regarding its performance, xAI claims that grok-code-fast-1 achieved a score of 70.8% on the SWE-Bench-Verified benchmark during internal evaluations. Nevertheless, the company emphasizes that its priority is real-world applicability, informed by feedback from seasoned developers who have commended the model for being “fast and reliable” in everyday coding tasks.
xAI initially introduced this model secretly under the name “sonic,” and it is now available to the public through API access. Users can also take advantage of a free trial for a limited period through xAI’s launch partners, which include GitHub Copilot, Cline, and Cursor. Furthermore, xAI has indicated that a new, more sophisticated version that will support multimodal inputs, extended context length, and parallel tool usage is already under development.
