Multi-Agent Coordination in Prod Dev: Mixing Model Families Beats a Single Model
CellistOk6782 · reddit · 2026-09-14
A developer shares their workflow for automating product development with AI agents: codify architecture, tech design, design system and outcomes upfront, then assign roles (task breakdown, test design, development, review, architecture, UX) to agents from different model families — Antigravity, GPT Sol, Opus 5, reserving Fable and Astra for critical work. Mixing model families outperforms a single model. The open problem is end-to-end orchestration: CLI-based routing still needs manual per-issue intervention and their custom router keeps needing iteration.
