A speedy daily driver While today's models are undeniably powerful, they often don't feel purpose-built for agentic coding workflows, where loops of reasoning and tool calls can feel frustratingly slow. As heavy users of agentic coding tools, our engineers saw room for a more nimble, responsive solution optimized for our day-to-day tasks. We built grok-code-fast-1 from scratch, starting with a brand-new model architecture. To lay a robust foundation, we carefully assembled a pre-training corpus ...
