Teens are upset that they can’t speak to Character.AI chatbots anymore

The platform has restricted access for those under 18, as concerns around the tech’s impact grow.

As far as execs at Character.AI are concerned, (role) playtime’s over for under-18s, as they start to ban teens from using the platform’s chatbots this week

The chatbot company, which clocks about 184 million website visits around the world each month — and millions more app sessions — per data from Similarweb, announced at the end of last month that it would be rolling back access to its open-ended chat feature for minors. Users who are under 18 have been limited to daily two-hour open-ended chats since the late October notice, and access started ramping down for most of those in the age range yesterday.

Indeed, a selection of young “power users,” as The Wall Street Journal termed them in a piece on the anguish some under-18 users are experiencing at being separated from the chatbots, are being given a weeks-long grace period where they can still access hour-long open-ended chats with the characters they’ve been interacting with, to “help minimize disruption” to the teen users.

Clearly, AI-generated conversations with popular characters like Yor Forger, “a loving mom who’s definitely not an assassin,” and Itoshi Rin, who “only loves soccer... and you,” have a lot of (mostly younger) users in the site’s full thrall.

Though traffic-tracking site Similarweb doesn’t break out under-18s in its demographics data, the figures it does disclose already show that Character.AI tends to skew a lot younger than more general competitors like ChatGPT.

According to US-specific figures from Similarweb, of the 1.7 million monthly unique web visitors character.ai notched on average from August to October, some 52% were aged between 18 and 24, compared to a 26% share on chatgpt.com.

A lot to talk about

Character.AI’s younger users tend to be way more locked in, too: per the data, they visited 26 times each month on average and spent 18 minutes in a typical session using Character.AI — much higher than ChatGPT users, who visited the OpenAI chatbot 13 times on average across the month, spending around 6 minutes per visit.

Those sorts of numbers, paired with deaths linked to the platform and increasing concerns around the detrimental effects of chatbots on younger minds more generally, were likely factors in the move to pare back teen user access, which — at least according to Character.AI CEO Karandeep Anand — “wasn’t a very hard decision.”

Report: SpaceX posted $18.5 billion in revenue and a $5 billion loss last year

All eyes on are SpaceX as it prepares for a blockbuster IPO as soon as this summer, and everyone is eager to get a look at the company’s official numbers for the first time.

The Information is reporting that last year, SpaceX posted $18.5 billion in revenue with a $5 billion loss.

According to the report, the numbers reflect the combined finances of SpaceX and xAI, which it acquired in February.

After acquiring xAI, SpaceX’s successful space launch and satellite business may have been dragged down by xAI’s massive data center spending. Earlier this year, Bloomberg reported that xAI had burned through $8 billion in the first nine months of 2025.

Report: Amazon hopes its Project Houdini modular data center plan is the trick to speed up construction

Amazon is looking for a magic trick that can help it get past data center construction bottlenecks so it can work through the $244 billion worth of cloud computing backlogs it wants to deliver.

It may have just pulled a rabbit out of its hat. (I know, groan.)

Business Insider is reporting that Amazon’s Project Houdini seeks to slash labor costs and installation time by building modular “data halls” — the rows of racks of servers that make up the heart of data centers — in factories, and then shipping them fully assembled on trailers to data center sites.

According to the report, the modular plan would save weeks of construction time and tens of thousands of hours of labor costs.

This week in Amazon’s letter to shareholders, CEO Andy Jassy wrote that the company is planning $200 billion in capital expenditure this year, and that it is embracing its tradition of taking big bets on experiments like Project Houdini:

“You need to invent and experiment like crazy. Many of these experiments will fail, and it might feel like you’re getting nowhere. But, your culture must possess the tenacity to keep at it.”

Creator of popular, mysterious “HappyHorse” text-to-video model is Alibaba

AI benchmark leaderboards are often where mysterious new models make their debut, stoking speculation about the unnamed companies behind them.

That was the case with an impressive new text-to-video model named HappyHorse-1.0 that shot to the top of public leaderboards. CNBC reports that Chinese tech giant Alibaba has confirmed that it is the owner of the new model.

HappyHorse beat out the popular Seedance model from rival ByteDance in blind human evaluations to claim the top spot on the Artificial Analysis text-to-video leaderboard.

While OpenAI has announced it is shuttering its text-to-video Sora app, the category continues to see intense competition as a flurry of video models improve with more realistic physics and cinematic effects.

OpenAI: Our new AI tool is too dangerous to release, too!

This week, Anthropic warned that it had developed a new model that was too dangerous to cybersecurity to be released to the public.

According to a new report, OpenAI is saying similar things about a new cybersecurity tool it is working on (separate from its rumored forthcoming Spud model).

Axios wrote that OpenAI is allowing a small group of partners to test its new AI tool, which has “advanced cybersecurity capabilities.”

The realization that we have arrived at an era of powerful new AI models that could overwhelm current cybersecurity defenses is spooking investors, with cybersecurity stocks like Cloudflare, Zscaler, CrowdStrike, and Palo Alto Networks all down sharply this morning.

OpenAI’s Stargate shrinks further as UK data center “paused”

OpenAI’s ambitious Stargate global data center project just got smaller.

First announced at the White House alongside President Trump at the start of his second term, the OpenAI partnership with Oracle and SoftBank sought to build massive data centers around the world, including sites in the UAE, the UK, and Norway.

Bloomberg reports that the company is “pausing” the Stargate UK project, citing high energy costs and regulatory obstacles.

Last month, the company and its partner Oracle scrapped its planned expansion of the Stargate I data center site in Abilene, Texas.

In a statement to Bloomberg, the company said:

“AI compute is foundational to that goal — we continue to explore Stargate UK and will move forward when the right conditions such as regulation and the cost of energy enable long-term infrastructure investment.”

Stargate UK was announced in September, including a partnership with Nvidia and Nscale that would scale up to 31,000 GPUs.
