Grok Build 0.1 vs Kimi K2.7-Code
Grok Build 0.1 and Kimi K2.7-Code both operate at the terminal-agent level. xAI's Grok Build emphasizes plan-first execution with up to eight parallel sub-agents in isolated Git worktrees. Moonshot's Kimi K2.7-Code emphasizes open weights, MCP JSON / Tool use evidence, multimodal input, and low-cost hosted or self-hosted deployment.
Pick Grok Build 0.1 when the product workflow needs xAI's CLI-native multi-agent orchestration and human-in-the-loop plan review. Pick Kimi K2.7-Code when open-weight deployment, MCP-heavy tool invocation, multimodal input, and lower input token cost matter more. Treat benchmark claims carefully: Grok Build's often-cited SWE-bench Verified 70.8% belongs to the retired grok-code-fast-1 predecessor, while Kimi K2.7-Code has no public SWE-bench or Terminal-Bench entry.
