What happened
- Nat Friedman, head of product at Meta Superintelligence Labs and former CEO of GitHub, wrote on X on September 22, 2026, that Muse, Meta’s AI assistant, “was built from scratch, but is clearly very inspired as a product by OpenClaw.”
- The acknowledgment came after users noticed that Muse repeats OpenClaw’s file structure, including a
SOUL.mdconfiguration file that defines personality and behavior, with nearly identical content. - In the same message, Friedman credited the coincidence to the good judgment of Peter Steinberger, creator of OpenClaw, and said that after using the project in January he bought hundreds of Mac minis for his team.
- OpenClaw is an open-source AI agent project. Steinberger joined OpenAI in February 2026.
Why it matters
- Muse reached the top spot in the U.S. App Store and is growing faster than ChatGPT did in its own mobile launch. The configuration convention it copied stops being a detail of an open project and becomes the format mass-market users will see.
- For any team that has already written agent instructions in OpenClaw’s format, the news is operational: that work carries over to Muse with almost no rewriting. It’s the kind of compatibility nobody announced, and it’s worth testing before redoing it.
- A public acknowledgment of inspiration, made by the product executive and not by the legal team, sets a position that’s hard to reverse if the matter ends up in court.
The number
1 configuration file, SOUL.md, was enough for the coincidence to stop being debatable. It defines personality and behavior parameters in both products.
Context
The pattern repeats: the formats of open projects end up inside mass-market products. Adobe did something similar when it opened 70 tools inside Slack, and Amazon showed the other extreme when it resold ChatGPT ads while restricting its access to Amazon’s store.
What’s next
- No timelines announced: neither Meta nor Steinberger reported legal action or agreements.
- Nor is there any announcement of formal compatibility between the two formats, although in practice it already exists.
Bottom line
Steinberger published OpenClaw in the open and now works at OpenAI. The decision that set his project on its course ended up defining, with no contract involved, how the assistant Meta put at the top of the store is configured.
