Summary

This is a short industry-news commentary on what happened to the AI coding IDE Windsurf. Its deal with OpenAI fell apart. Google hired the founders and researchers to build Antigravity, and Cognition, the maker of Devin, bought the rest of Windsurf. The creator thinks the Windsurf + Cognition combination worked out well for Devin. He also suggests that few people are using Antigravity right now.

Key points

• OpenAI's planned acquisition of Windsurf, an AI coding IDE, fell apart.
• Google hired Windsurf's founders and researchers to build Antigravity, its agentic coding environment, and possibly other ML work.
• The Windsurf staff who stayed, along with the product, went to Cognition, which already made the AI software-engineering agent Devin.
• The creator thinks Devin has improved a lot since then and credits the Windsurf + Cognition 'synergy'.
• The creator's opinion: Antigravity doesn't seem to be widely used yet.
• Wider lesson: AI coding tools are changing fast through acqui-hires and acquisitions, so check which tools are still actively developed before you commit to one.
