Aider CLI updated its Architect-Editor dual-model workflow. The setup pairs OpenAI o3-mini to analyze complex repository constraints and author architectural blueprints, while Claude 3.7 Sonnet writes fast, unified diff patches automatically committed to local Git branches.

Key Takeaways

  • βœ“Decoupled roles: reasoning models formulate plans while coding models produce fast diffs.
  • βœ“Integrates with local Git commit logs, generating conventional commit messages automatically.
  • βœ“Fully configurable with any model pairs (e.g. DeepSeek-R1 + Codestral 25.08) for cost control.
