Elon Musk's xAI has launched Grok Code Fast 1, an AI model for agentic coding workflows that processes 92 tokens per second and costs $0.20 per million input tokens—up to 95% cheaper than competitors. With 70.8% accuracy on the SWE-Bench benchmark, it features real-time collaboration with GitHub Copilot, X platform integration, and multi-language support. This autonomous AI agent can write, refactor, and maintain code independently, optimizing development and improving productivity. Currently available as a free public preview, Grok Code Fast 1 positions itself as a productivity leader against competitors like ChatGPT, Codex, and Tabnine through its speed, ecosystem access, and affordability.
