Cursor's Clever Algorithm: Character Prefix Conditioning for Accurate Code Completion
2025-01-11

Cursor's blog post dives into a crucial problem in AI code completion: handling character prefixes effectively. Traditional token-based sampling fails when the cursor isn't on a token boundary. The post introduces character prefix conditioning, an algorithm that samples based on character prefixes, ensuring completions start with user input. The post concludes with a challenge: devise an efficient algorithm to sample from this distribution while minimizing calls to the underlying language model.
