T3 Code is an "agent harness control surface". It enables control of the agents on your machine with a best-in-class mobile app (iOS, Android), web app and Electron-based desktop app. Works with your subscriptions on Claude Code, Codex, Cursor, Grok Build, and OpenCode. If they're set up on your computer, T3 Code can control them.

The model matters less than the harness now - agree or disagree?

July gave us GPT 5.6, Claude Opus 5, Sonnet 5, and the return of Fable 5.

Every new release reshuffles the benchmarks - but I m beginning to think the model is only half of the experience.

The harness around it increasingly decides how productive you actually are:

How well it understands your codebase
How it manages context across longer tasks
Whether you can run and review multiple agents
How clearly it presents diffs and changes
How easily you can switch models or continue work elsewhere
Whether it fits into your existing subscriptions and workflow
