Fable X GPT-5.6 SOL X Grok-4.5 X Muse Spark 1.1 ULTRA Coder: This OPENSOURCE WORKFLOW is CRAZY GOOD!
In this video, I'll be showing you a complete multi-model AI coding workflow using T3 Code, where Fable 5 handles planning and review, GPT-5.6 or Grok 4.5 handles backend implementation, and Muse Spark handles frontend design through OpenDesign. Instead of trying to use one model for everything, this setup puts each model in the lane where it performs best. -- Key Takeaways: 🚀 T3 Code now supports multiple major AI coding CLIs, subscriptions, and API providers in one interface. 🧠 Fable 5 works best as the planner and reviewer, especially for architecture, task breakdowns, and integration checks. ⚙️ GPT-5.6 and Grok 4.5 are strong backend implementation models, with Grok offering especially good value. 🎨 Muse Spark is excellent for frontend and visual design work when used through OpenDesign. 🌳 T3 Code worktrees let multiple agents work in parallel without stepping on each other’s files. 💸 This workflow keeps costs low by using expensive models only for high-value planning and review. 🛠️ The final stack feels like a practical AI engineering team, with each model handling the job it is best suited for.
