• I'm not able to find an open issue that requests the same enhancement

Problem

R1 as architect with Sonnet as editor has set a new SOTA of 64.0% on the aider polyglot benchmark. They achieve this at 14X less cost compared to the previous o1 SOTA result.

Solution

Ex: Aider supports using a pair of models for coding:

• An Architect model is asked to describe how to solve the coding problem. Thinking/reasoning models often work well in this role.
• An Editor model is given the Architect’s solution and asked to produce specific code editing instructions to apply those changes to existing source files.
