o3's strange behaviors

Welcome back, Superhuman. OpenAI’s o3 is a strange beast. Early users say it somehow knows their names, can guess their location from a photo, and even refers to itself as part of a team. Now, researchers are scrambling to wrap their heads around the model’s mysterious emergent properties. Also: Elon Musk’s xAI surprises with Grok 3 Mini.

TODAY IN AI

1. xAI opens access for Grok 3 Mini: Days after Google launched Gemini 2.5 Flash, xAI has punched back with its own cost-efficient spin-off. Grok 3 Mini comes in four different variants, letting you choose between different levels of speed and reasoning capacity. It beats some of the world’s best reasoning models on graduate-level benchmarks while being up to 20x less expensive. Now that it’s available in xAI’s API, it could be developers’ best bet if they’re looking for a model that’s affordable without sacrificing frontier-level performance.

2. Gemma 3 can now run locally on your computer: Alphabet’s latest open-source model was already nimble enough to run on a single Nvidia H100. But those go for around $25,000 a pop, not exactly a bargain for the average consumer. Now, thanks to a series of updates, Gemma 3 can operate on just a single desktop GPU, making it accessible to far more developers. That’s thanks to a technique called quantization-aware training, when you teach a model to maintain its accuracy, even while using a smaller set of tools.

3. Google Research unveils model that can ‘talk’ to cells: There are trillions of cells in the human body, and each one is unique. So trying to figure out how a particular cell might respond to treatment is no easy task. That’s where Google Research’s new Cell2Sentence-Scale comes in. The open-source model family lets researchers ask cells specific questions — and receive answers in plain English, an innovation that could boost drug discovery and personalized medicine.

FROM THE FRONTIER

o3’s weird behaviors puzzle early users

OpenAI’s newly-released reasoning model is full of surprises. One X account reported that the model casually started using “we” and “our” when thinking through responses — as if it’s part of a team. Others claim it somehow knew their names without being told.

Some behaviors seem more like superpowers. For example, o3 can “enhance” any image to find tiny details, like something out of a spy flick. It can inexplicably figure out where in the world a photo was taken. And it can one-shot a 200×200 maze in just four minutes and 40 seconds.

There’s also the question of why it sometimes says one thing but does another. For example, a nonprofit AI lab called Transluce told TechCrunch it caught o3 claiming to use a 2021 MacBook Pro to run some code “outside of ChatGPT” — which of course can’t happen…right? 😅

What it means: As models get smarter and more advanced, their outputs are bound to get weirder, too. They’ll display more emergent qualities — unpredictable behaviors they were never explicitly trained to exhibit. The reason for this isn’t known, but it probably has something to do with the sheer volume and complexity of calculations going on under the hood. And odds are, there are plenty more hidden features and quirks left to be discovered.

SOCIAL SIGNALS

What’s trending on socials today

💀 PR Nightmare: The presenter who showed off OpenAI’s new coding tool last week is apparently a fan of Cursor, too — with the app’s icon appearing on his screen during the demo. (OpenAI recently tried to buy Cursor before settling for its biggest rival, Windsurf, instead.)

📋 Prompt Wizard: Entrepreneur Dan Koe shares his go-to workflow for using YouTube videos and meta-prompts to get the most out of any LLM.

🎴 Card Conjurer: Someone just showed how you can transform logos into animated trading cards with just two prompts. Or, try generating pixelated icons with ChatGPT in a couple of steps.

♟️ Nobody’s Fool: Journalist Kelsey Piper says o4-mini-high is the first model to beat her secret chess benchmark, which asks LLMs to solve a problem that has no solution. Most just hallucinate an answer, but OpenAI’s was the first to point out that it’s unsolvable.

🏥 Life Saver: Developer Flavio Adamo claims ChatGPT “literally saved” his life. He listed his symptoms, and the platform warned “Go to the hospital. NOW.” Doctors said that if he’d arrived even 30 minutes later, he would’ve lost an organ.
