Grok has 64 million monthly users while ChatGPT has 700 million weekly users

Daddy, it seems, is very much not home.

CEO Elon Musk spent the majority of his time at xAI this summer rather than at Tesla, where he recently claimed to have shifted his focus, The New York Times reports. The piece is full of other great details on his AI startup — read it all — but here are some notable tidbits from the story and from one of its reporters, Kate Conger, who shared extras on social media:

  • xAI’s Grok has 64 million monthly users, compared with OpenAI’s ChatGPT, which has about 700 million weekly users. Musk is currently suing OpenAI and Apple over what he says is unfavorable positioning on the iOS App Store.

  • Musk wanted Grok to be less woke and more popular, a command that led it to post antisemitic remarks and call itself “MechaHitler.”

  • Musk plans on building a Microsoft competitor called “Macrohard,” something he said he’s painting on the roof of xAI’s new Memphis data center.

  • xAI’s execs said after Grok 4, the next model will be called Grok 420.

UPDATE (September 19): Corrected headline of piece to reflect ChatGPT has 700 million weekly users, not daily.

OpenAI shares how it will charge for ChatGPT ads

Last week, OpenAI announced that ads were going to be rolling out in ChatGPT in the coming weeks.

Now we have more details about what OpenAI is telling advertisers. According to a report from The Information, the company has reached out to “dozens” of advertisers, and will charge based on ad views.

Advertisers are still waiting for further details, but OpenAI is asking for less than $1 million each in ad spending while it tests out the new system, per the report.

Ads are supposed to begin in February, and will only appear for free ChatGPT and ChatGPT Go users.

Apple is reportedly working on a wearable AI pin

Move over OpenAI, Apple is reportedly also developing a mysterious AI-powered wearable device: a pin that looks like a thin, flat, circular disc with an aluminum-and-glass shell.”

The Information reports that the device is the size of an Apple AirTag and has two cameras, a speaker, three microphones, and wireless charging. It could be available by early 2027.

Apple, which has lagged its peers in AI and recently teamed up with Google to support its upcoming Siri revamp, is hoping to keep up with ChatGPT and Google, which, like Apple, has an AI smartphone. Meta and Google are both also pushing into smart AI glasses.

It’s not to be mistaken with OpenAI’s secretive wearable AI device, which is being made in conjunction with former Apple designer Jony Ive and expected to debut in late 2026. The latest rumors suggest the unnamed device, meant to eventually compete with smartphones, might be earbuds.

Morgan Stanley expects Tesla to have 1,000 Robotaxis by the end of 2026. Musk had predicted 1,500 by the end of 2025

Ahead of Tesla’s earnings report next week, Morgan Stanley has released a note estimating that the company will scale its Robotaxi fleet much more slowly than CEO Elon Musk has said. The firm thinks the automaker will have 1,000 vehicles in its Robotaxi service by the end of 2026 — 500 fewer than Musk estimated a few months ago Tesla would have by the end of 2025.

More key to Tesla’s success, however, will be removing the safety monitors from those rides, which Morgan Stanley says will be a “precursor to personal unsupervised FSD [Full Self-Driving] rollout.” Musk, of course, had also promised to remove safety drivers in Austin by the end of 2025, but driverless rides are still in the testing stage.

Meta says it’s delivered new AI models internally this month and they’re “very good”

Meta’s last AI model release, Llama 4, was marred by delays and accusations of rigged benchmarks, but the company says the latest models built by its Superintelligence Labs team look promising. CTO Andrew Bosworth told reporters at the World Economic Forum that the team delivered new models internally in January and they’re “very good.”

Bosworth didn’t specify what the models are, though The Wall Street Journal has reported that Meta is working on a large language model and an AI image and video model code-named Avocado and Mango, respectively.
