Is Grok Code Fast 1 Worth It?

xAI just released Grok Code Fast 1. Is it a coding game-changer? Here’s the quick take 👇 • Optimized for agentic workflows: code gen, debugging, full-stack dev • Pricing: $0.20/M input, $1.50/M output → ~10x cheaper than GPT-5 and Claude 4 Sonnet, slightly cheaper than GPT-5 mini • Speed: 160 tok/sec vs 50–90 tok/sec for Claude, GPT-5, Qwen → great for larger projects • Context: 256K (upgrade from 128K, on par with recent models) • Benchmarks: SWE-bench score ≈ Claude’s, but faster + cheaper • Trained with heavy RL using expert developer feedback → better tuned for real workflows potentially Verdict Not revolutionary, but very promising: – Much cheaper than Claude with similar results – Super fast for bigger projects – A strong alternative worth testing if coding is your main use case I’m Louis-François — PhD dropout, now CTO & co-founder at Towards AI.
