Building on yesterday's News about the OpenAI-Astral acquisition, OpenAI acquired Astral (a Python devtools company), continuing a trend of major AI labs purchasing developer tooling companies (following Google DeepMind's Antigravity acquisition and Anthropic's Bun purchase). OpenAI is also unifying ChatGPT and Codex into a single 'superapp,' signaling a major strategic consolidation around coding and enterprise.

The news today of OpenAI acquiring Astral completes a loop first opened by GDM when they bought what became the Antigravity team last July, and then Anthropic’s purchase of Bun last December. Astral joins OpenClaw and (to a lesser extent) gpt-oss and Whisper in OpenAI’s growing list of top tier open source AI projects.This comes against the backdrop of Fidji Simo explicitly dropping “side quests” like Shopping (with key partner Walmart reporting awful conversion about 1/3
