Split your coding stack: flagship model for planning, lighter one for implementation
kevinkern · x · 2026-10-01
kevinkern suggests pairing models in coding workflows: a flagship (Opus 5.5:main / GPT Astra 6:main) drives planning while a lighter implement-focused model (Sonnet 5.5:implement / GPT Sol 6.1:implement) writes the code, asking which pairing people prefer. The main/implement split workflow is gaining traction in the community.
