A March 22 tweet teased xAI releasing a direct OpenClaw competitor with 8 Grok AI agents working in parallel, 'Macrohard' computer-use for browser and tool operation, and Grok Code/Build for full-stack vibe coding. Phase 2 research confirms this aligns with Grok Build (announced January 12, still on waitlist): a local-first CLI agent at 70.8% SWE-Bench Verified with 256K context and a forthcoming Arena Mode where agents compete and outputs are algorithmically ranked before human review. Full public availability not yet confirmed by xAI.
