All the AI news of the week: Hands-on with Metas AI app, ChatGPT and and leaderboard drama
Just like AI models, AI news never sleeps.
Every week, we’re inundated with new models, products, industry rumors, legal and ethical crises, and viral trends. If that’s not enough, the rival AI hype/doom chatter online makes it hard to keep track of what’s really important. But we’ve sifted through it all to recap the most notable AI news of the week from the heavyweights like OpenAI and Google, as well as the AI ecosystem at large. Read our last recap, and check back next week for a new edition.
Another week, another batch of AI news coming your way.
This week, Meta held its inaugural LlamaCon event for AI developers, OpenAI struggled with model behavior, and LM Arena was accused of helping AI companies game the system. Congress also passed new laws protecting victims of deepfakes, and new research examines AI’s current and potential harms. Plus, Duolingo and Wikipedia have very different approaches to their new AI strategies.
What happened at Meta’s first LlamaCon

At LlamaCon, Meta’s first conference for AI developers, the two big announcements were the launch of a standalone Meta AI app to compete more directly with ChatGPT and the Llama API, now in limited preview. Following reports that this was in the works, CEO Sam Altman once joked that maybe OpenAI should do its own social media app, but now that is reportedly happening for real.
We also went hands-on with the new Llama-powered Meta AI app. For more details about Meta AI’s top features, read Mashable’s breakdown.
During LlamaCon’s closing keynote, Mark Zuckerberg interviewed Microsoft CEO Satya Nadella about a bunch of trends, ranging from agentic AI capabilities to how we should measure AI’s advancements. Nadella also revealed that up to 30 percent of Microsoft’s code is written by AI. Not to be outdone, Zuckerberg said he wants AI to write half of Meta’s code by next year.
ChatGPT has safety issues, goes shopping
Meta AI and ChatGPT both got busted this week for sexting minors.
OpenAI said this was a bug and they’re working to fix it. Another ChatGPT issue this week made the latest GPT-4o update too much of a suck-up. Altman described the model’s behavior as “sycophant-y and annoying,” but users were concerned about the dangers of releasing a model like this, highlighting problems with iterative deployment and reinforcement learning.
OpenAI was even accused of intentionally tuning the model to keep users more engaged. Joanne Jang, OpenAI’s head of model behavior, jumped on a Reddit AMA to do damage control. “Personally, the most painful part of the latest sycophancy discussions has been people assuming that my colleagues are irresponsibly trying to maximize engagement for the sake of it,” wrote Jang.
Earlier in the week, OpenAI announced new features to make products mentioned in ChatGPT responses more shoppable. The company said it isn’t earning purchase commissions, but it smells an awful lot like the beginnings of a Google Shopping competitor. Did we mention OpenAI would buy Chrome if Google is forced to divest it? Because they totally would, FYI.

The ChatGPT maker has had a few more problems with its recent models. Last week, we reported that o3 and o4-mini hallucinate more than previous models, by OpenAI’s own admission.
Anyone in the U.S. can now sign up for Google AI Mode
Meanwhile, Google is barreling ahead with AI-powered search features. On Thursday, the tech giant announced that it’s removing the waitlist to test out AI Mode in Labs, so anyone over 18 in the U.S. can try it out. We spoke with Robby Stein, VP of product for Google Search, about how users have responded to its AI features, the future of search, and Google’s responsibility to publishers.
Google also updated Gemini with image editing tools and expanded NotebookLM, its AI podcast generator, to over 50 languages. Bloomberg also reported that Google has been quietly testing ads inside third-party chatbot responses.
We’re keeping a close eye on that final development, and we are very curious how Google plans to inject ads into AI search. Would you trust a chatbot that gave you sponsored answers?
Leaderboard drama
Researchers from AI company Cohere, Princeton, Stanford, MIT, and Ai2, published a paper this week calling out Chatbot Arena for essentially helping AI heavyweights rig their benchmarking results. The study said the popular crowdsourced benchmarking tool from UC Berkeley allowed Meta, Google, OpenAI, and Amazon “extensive private testing” and gave them more prompt data, which “significantly” improved their rankings.
In response, LM Arena, the group behind Chatbot Arena said “there are a number of factual errors and misleading statements in this writeup” and posted a pointy-by-point rebuttal to the paper’s claims on X.
This Tweet is currently unavailable. It might be loading or has been removed.
The issue of benchmarking AI models has become increasingly problematic. Benchmark results are largely self-reported by the companies that release them, and the AI community has called for more transparency and accountability by objective third parties. Chatbot Arena seemed to provide a solution by allowing users to choose the best responses in blind tests. But now LM Arena’s practices have come into question, further fueling the conversation around objective evaluations.
A few weeks ago, Meta got in trouble for using an unreleased version of its Llama 4 Maverick model on LM Arena, which scored a high ranking. LM Arena updated its leaderboard policies, and the publicly available version of Llama 4 Maverick was added instead, ranking way lower than the unreleased version.
Lastly, LM Arena recently announced plans to form a company of its own.
Regulators and researchers tackle AI’s real-world harms
Now that generative AI has been in the wild for a few years, the real-world implications have started to crystallize.
This week, U.S. Congress passed the “Take It Down” Act, which requires tech companies to remove nonconsensual intimate imagery within 48 hours of a request. The law also outlines strict punishment for deepfake creators. The legislation had bipartisan support and is expected to be signed by President Donald Trump.
The nonpartisan U.S. Government Accountability Office (GAO) published a report on generative AI’s impact on humans and the environment. The conclusion is that the potential impacts are huge, but exactly how much is unknown because “private developers do not disclose some key technical information.”
And in the realm of the frighteningly real and specific harms of AI, a study from Common Sense Media said AI companion apps like Character.AI and Replika are unequivocally unsafe for teens. The researchers say if you’re too young to buy cigarettes, you’re too young for your own AI companion.
Then there was the report that researchers from the University of Zurich secretly deployed AI bots in the r/changemyview subreddit to try and convince people to change their minds. Some of the bot identities included a statutory rape victim, “a trauma counselor specializing in abuse,” and “a black man opposed to Black Lives Matter.”
Other AI news…
In other news, Duolingo is taking an “AI-first” approach, which means replacing its contract workers with AI whenever possible. On the flip side, Wikipedia announced it’s taking a “human-first” approach to its AI strategy. It won’t replace its volunteers and editors with AI, but will instead “use AI to build features that remove technical barriers to allow the humans at the core of Wikipedia.”
Yelp deployed a bunch of AI features this week, including an AI-powered answering service that takes calls for restaurants, and Governor Gavin Newsom wants to use genAI to solve California’s legendary traffic jams.

Hurdle hints and answers for April 19, 2026
If you like playing daily word games like Wordle, then Hurdle is a great game to add to your routine.
There are five rounds to the game. The first round sees you trying to guess the word, with correct, misplaced, and incorrect letters shown in each guess. If you guess the correct answer, it’ll take you to the next hurdle, providing the answer to the last hurdle as your first guess. This can give you several clues or none, depending on the words. For the final hurdle, every correct answer from previous hurdles is shown, with correct and misplaced letters clearly shown.
An important note is that the number of times a letter is highlighted from previous guesses does necessarily indicate the number of times that letter appears in the final hurdle.

Star Trek’s Most Ambitious Villain Helped Create The Franchise’s Most Complex Hero
By Chris Snellgrove
| Published
When Star Trek: Voyager first came out, the most fascinating character was the Doctor. While Robert Picardo’s performance was superb, it’s fair to say this character was mostly fascinating on a conceptual level. We had seen things like hypercompetent Starfleet captains and exotic aliens before, but what we hadn’t seen was a fully holographic chief medical officer. Voyager’s Emergency Medical Hologram seemed like the perfect embodiment of the Star Trek ethos. He’s a technological strange new world and new life, all rolled into one.
However, what casual audiences didn’t realize is that the Doctor wasn’t completely unique. Long before Picardo’s character ever sawed bones in the Delta Quadrant, Captain Picard dealt with another extraordinary hologram: Moriarty, the brilliant foe of the famous investigator Sherlock Holmes. Over on The Next Generation, Geordi LaForge accidentally created this villain as a sentient hologram when he asked the holodeck to create a challenge worthy of the android Data. Later, Star Trek: Voyager executive producer Jeri Taylor revealed that, in-universe, the holographic Doctor was created because Starfleet took advantage of the same accidental breakthrough that created Moriarty!
It all started in “Elementary, My Dear Data,” the Next Generation episode in which the titular android and Geordi LaForge recreated Sherlock Holmes’ adventures on the holodeck. Thanks to his positronic brain and his encyclopedic knowledge of Sir Arthur Conan Doyle’s Holmes novels, Data is able to easily solve every mystery that is thrown at him. That’s when Geordi makes a seemingly simple request. He asks the Enterprise computer to develop a holodeck foe that could actually defeat Data, one of the smartest beings in the entire galaxy.
The computer obliges and creates a sentient version of Moriarty, Sherlock Holmes’ greatest foe. Following Geordi’s instructions, the Enterprise computer included much of Data’s vast programming, which resulted in the holographic character becoming self-aware. Moriarty ended up threatening the Enterprise on two different occasions, and Picard eventually got rid of him by trapping the unknowing villain in a simulation where he thought he had left the holodeck and could explore the stars. This was meant to be a happy ending for Moriarty, but in the show’s typically bleak fashion, Star Trek: Picard later showed us a different, more hostile version of this character created by a malevolent Section 31 AI.
How A Villain Created A Hero
What does all of this have to do with Robert Picardo’s holographic Doctor on Star Trek: Voyager? Elementary, my dear reader! Very early in Voyager’s development (the show didn’t even have a name yet), executive producer Jeri Taylor was inspired by Moriarty to create a new character. As reported in A Vision of the Future-Star Trek: Voyager, Taylor wrote down notes for a holographic doctor “who, like Moriarty, has ‘awareness’ of himself as a holodeck fiction. He longs for the time when he can walk free of the Holodeck.”
A few days later, she wrote down additional notes that contain a startling bit of Star Trek lore. “The Holo-Doctor represents a new, state-of-the-art technology which has capitalized on the serendipitous incident which created Moriarty, and has programmed a holographic character which has self-awareness of his situation and limitations.” While Moriarty is name-dropped on Voyager a couple of times, the show never mentioned what Taylor’s notes seem to confirm: that Lewis Zimmerman could never have created the Emergency Medical Hologram program if not for Geordi LaForge accidentally creating Moriarty on the holodeck.
From Villain To Leading Man?
If that’s not strange enough, there was a period of time when Voyager’s producers were considering making Moriarty a mainstay character on the show. As reported in Star Trek–Where No One Has Gone Before, Taylor’s notes mentioned that “everyone agreed that was a little too broad, and we couldn’t figure out why anyone would take him along.” After dismissing the idea, they decided “that having a holographic doctor with the full consciousness of being a hologram might be fun, and we’d never done anything like that before, except for Moriarty.”
There you have it, gentle reader. Without the character of Moriarty on Star Trek: The Next Generation, we’d never have the Doctor on Voyager. In this way, Trek’s most ambitious villain helped create the franchise’s most complex hero. Thanks to Jeri Taylor’s notes, we also know that, in-universe, Lewis Zimmerman would never have been able to create the Doctor if not for Geordi accidentally creating a sentient Moriarty so Data could have fun. In retrospect, this does make Zimmerman’s arrogance that much weirder. After all, he has a lot of attitude for someone who owes his entire career to the two biggest book nerds in the galaxy!

Moon phase today: What the Moon will look like on April 19
After days of almost (and complete) darkness, the Moon is finally starting to reappear. We’re currently in the Waxing Crescent phase of the lunar cycle, which means each night until the Full Moon we’ll see it get more illuminated from the right side.
What is today’s Moon phase?
As of Sunday, April 19, the Moon phase is Waxing Crescent. Tonight, 5% of the moon will be lit up, according to NASA’s Daily Moon Guide.
Despite more of it now being illuminated, the percentage of surface is still too little to be able to spot any surface details. Check again tomorrow.
When is the next Full Moon?
The next Full Moon is predicted to take place on May 1, the first of two in May.
What are Moon phases?
NASA states that the Moon takes about 29.5 days to orbit Earth, during which it passes through eight distinct phases. We always see the same side of the Moon, but the amount of sunlight reflecting off it changes as it moves along its orbit, creating the familiar pattern of full, partial, and crescent shapes. We call these the lunar phases, and there are eight in total:
New Moon – The Moon is between Earth and the sun, so the side we see is dark (in other words, it’s invisible to the eye).
Mashable Light Speed
Waxing Crescent – A small sliver of light appears on the right side (Northern Hemisphere).
First Quarter – Half of the Moon is lit on the right side. It looks like a half-Moon.
Waxing Gibbous – More than half is lit up, but it’s not quite full yet.
Full Moon – The whole face of the Moon is illuminated and fully visible.
Waning Gibbous – The Moon starts losing light on the right side. (Northern Hemisphere)
Third Quarter (or Last Quarter) – Another half-Moon, but now the left side is lit.
Waning Crescent – A thin sliver of light remains on the left side before going dark again.
