Yes, aider can also work in architect/editor mode [0] which tends to produce the best results [1]. An architect model solves the coding problem and describes the needed changes however comes naturally to it. The editor model then takes that solution and turns it into correctly formatted instructions to edit the files.

Too much context can still confuse the LLMs in this situation, but they may be somewhat more resilient.
