Top picks for Code Refactoring (2026)
Safely restructuring an existing codebase across many files. Ranked from 405 live models on the OpenRouter catalog, weighted for context window, reasoning quality, structured output.
What this is
Ranked by capability match + real benchmark scores (Aider Polyglot, Artificial Analysis Intelligence Index) + live pricing. Models need the right specs for Code Refactoring, then benchmark performance refines the order. Full methodology →
