Hot signal: Grok 4.6 joins Copilot’s model bench
The coding assistant race is shifting from one default model to a routed set of agents.
GitHub says Grok 4.6 is rolling out in GitHub Copilot, with positioning around agentic coding and complex multi-step workflows. The same weekly release cycle also mentions new models, portable plugins, and smoother agent workflows across editors, command line, and the Copilot app. The practical shift is simple: Copilot is becoming a place to compare coding agents against specific jobs, not just a chat box inside an editor. Treat this as a test item, not a default switch. Run Grok 4.6 on one contained implementation branch and compare it against the current model on correctness, review time, and cleanup required.
