Which AI produces better results?
Aider generates repository-level context with multi-file edits using your choice of Claude 3.5, GPT-4, or 50+ other models. Tabnine's proprietary models trained only on permissively licensed code produce more conservative suggestions but lack the context depth. Aider's architect/editor approach produces SOTA benchmark results per November 2024 updates.
