xAI launches Grok Build agentic CLI and ships Grok 4.6 on Bedrock

xAI officially released Grok Build 1.0.0, an agentic command-line tool capable of operating a user's computer, graduating from betas that began in May. Grok 4.6—carrying an intelligence score of 61, tying GPT-5.6 Sol Max—was integrated into Grok Build on August 12 and is now available on Amazon Bedrock with a 500K-token context, cross-region inference routing across US and global regions, and pricing of $2/$6 per 1M input/output tokens. xAI also launched Grok Bot, a $300/month persistent cloud-agent service.

The Bedrock listing (AWS labels the provider 'SpaceXAI') is strategically significant: it places Grok inside AWS's managed model storefront alongside OpenAI and Anthropic offerings, letting enterprise developers reach it through a single interface and dramatically lowering adoption friction.

Competitively, price is xAI's lever. Developers praised Grok 4.6 as a cost disruptor at roughly $8 per 1M combined tokens versus $30-60 for Opus/Sonnet-tier models. That undercuts the premium frontier tier and pairs with Google's Gemini Flash pricing to squeeze the high end.

The frictions: developers flagged a long-context billing cliff that doubles pricing past 200K tokens—a real problem for agent workloads that accumulate context. And a key multimodal team lead reportedly departed xAI for Tencent, feeding chatter about intensifying US–China talent competition. Watch whether Grok Build's 'runs your computer' capability draws the same security scrutiny now hitting agentic tools industry-wide.
