Study finds async AI coding agents drive far bigger output gains than autocomplete
NathanpmYoung · x · 2026-07-25
A figure from a study on AI coding tools compares productivity gains across three generations of tooling:
- Autocomplete (e.g. GitHub Copilot at launch)
- Sync agents (e.g. Claude Code run locally)
- Async agents (e.g. OpenAI Codex run remotely)
The chart shows the biggest gains from asynchronous agents, with roughly:
- 17.3× more lines of code
- 3.9× more files touched
- 2.8× more commits
- 2.5× more pull requests
- 1.5× more repos touched
- 1.3× more releases
The takeaway is that more agentic workflows appear to correlate with much larger throughput changes than classic autocomplete.
