You're caught up.

That's everything that changed at the five labs.

See the 328 items we left out, and why

Nothing is hidden. Here is everything Enough.ai read today that didn't make the page, grouped by the reason it was left out. Most AI news is this.

Repeats and syndication134

These were extra write-ups of stories above (Gemini 4 Argon, The X Subscription, Anthropic's self-replication warning) or of stories from yesterday with nothing new: Muse Wonder, the false police tip, OpenAI's Dublin jobs, Gemini's free tier and the Critical Infrastructure Defense Program, where the only new detail was CrowdStrike joining.

Opinion and analysis60

Columns, surveys, explainers, how-to guides and reactions, including commentary on Zuckerberg's spending, Sam Altman's interviews and Anthropic's stance on AI welfare.

Not really about the company36

These only mention a company in passing, such as AI stock picks, ChatGPT used as a tool in unrelated stories, telecom and laptop launches, and stories about Elon Musk outside xAI.

Other31

Customer stories, partner-program sign-ups, hires, help-page updates, sponsored deals, testimony and hearings, a Dutch privacy group's plan to sue over Meta glasses that has not been filed, and GitHub's own change to scanning for Anthropic keys.

Stock and valuation chatter28

Pieces on Anthropic's planned investor meeting and possible IPO, pre-IPO trading products, IREN, Meta and SpaceX analyst calls, and market moves linked to OpenAI, none describing a concrete deal.

Single-source rumors27

Each of these rests on one outlet or one scoop, including the reported NTT Data centre in Japan for Anthropic, OpenAI reportedly firing three safety researchers, Reuters' exclusive on AI labs and outside evaluators, an Apple court win over OpenAI files, Gemini's Spark agent, and an xAI rebrand.

Older news11

Fresh coverage of things announced days ago: Anthropic's usage policy rules on abusive users, ChatGPT's EU watermarks, interactive answers, ad formats and Dot, plus an old ads revenue figure and a pre-launch Gemini tweet.

Hype and speculation1

A piece about where Anthropic might build data centres in Australia, with nothing decided.
