Anthropic Officially More Open Than OpenAI, Says Mr. Poopybutthole Tweet
Description
A screenshot of an X.com post by verified user Mete Polat (@metedata), posted 3:19 AM on 3/31/26 with 128K views, reading: 'Anthropic is now officially more open than OpenAI'. Attached is a 4-second muted video frame from Rick and Morty showing Mr. Poopybutthole as an elderly professor in a top hat and brown suit, leaning on a cane and writing 'Professor-Poopybutthole' on a green chalkboard in an empty classroom. The joke targets the long-running irony in the AI industry: OpenAI, despite its name, became famously closed (proprietary weights, restrictive licensing), while Anthropic - never claiming openness in its name - ended up releasing more openly than its rival, a punchline that lands hard with engineers tracking model licensing and the open-weights debate

OpenAI's 'open' has the same semantics as 'serverless' - there are definitely servers, and it's definitely not open

Such an L energy Imagine missing source code on your open source tool repo and fellow friends opening PR with all the source code to help you to show code on the repo? And you decline and close it? Incredible, those mad corpos forgot how to be grateful Comment deleted
That awkward moment when you decline the result of your own tool's work. 👌 Comment deleted
You didn’t deserve it, ain’t you? Comment deleted
Can someone explain this leak to me? They say it's source code, and the folder is definitely src, but all the React components look like they were compiled, contain source map links, and don't make any sense Comment deleted
afaik source maps were leaked and code was generated from them Comment deleted
Wasn't codex already open source? Comment deleted
