The setup assigns each AI model a specific role based on its strengths and cost profile: Fable 5 (Claude) handles planning and architecture in plan mode, Grok 4.5 or GPT 5.6 handles backend implementation due to token efficiency and cost, and Muse Spark handles frontend/design work via Open Design. Key insights include using expensive models sparingly for high-value planning tasks, isolating Muse Spark to its own work tree to prevent file conflicts, and leveraging T3 Code's multi-provider support to run Claude, Codex, Grok, and raw API keys side-by-side. The full invoicing app demo cost less than a single Fable-only session. ## Full article daily.dev links to this article rather than hosting it.
