Kimi K2.6 vs Grok Build 0.1

Moonshot AI's flagship, built for agents and long-horizon coding rather than single prompts. Kimi K2.6 is designed to run end-to-end coding tasks and orchestrate swarms of sub-agents that decompose work autonomously. It reads text and images, with video handling still experimental. Its context window is smaller than most frontier models. Open-weight under a modified MIT licence, so the weights are public and self-hostable.

xAI's coding model, purpose-built for autonomous software engineering rather than chat. Grok Build 0.1 acts as an engineering agent: it reasons through a problem, writes code, runs your terminal, checks for errors, and fixes its own mistakes in a loop. It reads text and images, always reasons before answering, and natively supports Model Context Protocol. Built for long-horizon coding that runs with little supervision, at a low cost, tuned for agent loops.
