On the second day of “shipmas,” Sam Altman previewed for me... model fine-tuning ability

For day 2 of OpenAI’s “12 days of OpenAI” event, the company showed a preview of a new feature that will let users customize its models for specialized uses such as legal, financial, engineering, and insurance applications.

Opening up the ability for developers to easily use “reinforcement fine-tuning” — a technique the company uses internally to improve its models — will help developers create “expert models fine-tuned to excel at specific sets of complex, domain-specific tasks,” the company said.

OpenAI archrival Meta has touted the ability to distill or refine its largely open Llama 3.1 AI model for any application.

As the big foundational AI models achieve a degree of feature parity, the ability to tailor them to specialized applications with custom data will become more important in an already competitive landscape.

OpenAI is accepting applications from researchers who work in law, medicine, healthcare, finance, or engineering to help test the tool, which the company said will be publicly available early next year.

Meta pushes deeper into AI robots with acquisition

Meta just bought robotics AI startup Assured Robot Intelligence, Bloomberg reports, doubling down on its push into humanoid tech. The team will join Meta’s Superintelligence Labs to build models that let robots “understand, predict and adapt to human behaviors in complex environments.”

The goal, Bloomberg says, is to be the Android of robots: building the software and hardware foundation others can use.


The move comes right after China forced Meta to let go of its acquisition of agentic AI startup Manus.

Apple’s capital spending is heading the opposite direction of Big Tech

The big story in Big Tech has been just how much they’re spending on capex to furnish their AI futures. Not only are Alphabet, Amazon, Meta, and Microsoft spending more than ever, they’re also spending more than they said they would just a quarter earlier. In total, their 2026 capital expenditure bill is now slated to surge beyond $700 billion.

Apple, by contrast, continues to take a different approach. The company has lagged peers in developing its own frontier AI models and has leaned more on partnerships. The strategy certainly doesn’t seem to be hurting Apple yet. The company posted record revenue in the March quarter that beat analysts’ expectations this week, even without a robust AI offering.

Apple’s capex actually fell in the March quarter. Its payments for acquisition of property, plant, and equipment totaled about $1.9 billion in its fiscal second quarter, down 36% from roughly $3 billion a year earlier. So on a year-over-year basis, Apple’s capex declined while everyone else’s jumped sharply.

Tim Cook: Popular Mac mini and Mac Studio will be constrained for “several months”

Apple may have missed out on the first wave of generative AI when it comes to software, but its hardware is another story.

The current OpenClaw craze — where users run their own AI agents on a dedicated computer in their homes, and chat with it via messaging apps — has made the once sleepy Mac mini and pro-level Mac Studio an unlikely hit.

Reports of shortages are not lost on Apple.

During this week’s earnings call, outgoing CEO Tim Cook acknowledged the supply constraint of the popular desktops:

“On the Mac mini and the Mac Studio, both of these are amazing platforms for AI and agentic tools, and the customer recognition of that is happening faster than what we had predicted. And so we saw higher-than-expected demand.”

Cook noted that the Mac mini was the top-selling desktop computer in China last quarter, where the DIY agentic AI boom is especially popular. In addition to strong customer demand, Cook cited supply chain constraints adding to the problem, which “may take several months to reach supply/demand balance.”

The Mac mini is one of the products that Apple will be making in the US starting later this year.

Apple’s iPhone is the top-selling smartphone in urban China

Apple’s second-quarter earnings beat expectations and underscore its growing strength in China, where it is closing in on the top spot in the smartphone market.

“We are thrilled with the performance in Greater China,” CEO Tim Cook said, noting that the iPhone was “the top-selling model in urban China.” Cook first called the iPhone the rather than a top-selling model there during the company’s first-quarter earnings earlier this year.

Data from IDC and Counterpoint Research shows Apple accounted for 19% of smartphone shipments in China in the first calendar quarter of 2026, just behind Huawei at 20%. Analysts say Apple is poised to take the lead soon, helped in part by rising memory chip costs, which are pushing up competitors’ prices.

Apple’s China revenue rose 28% in the March quarter, ahead of analyst estimates, and is up 33% in the first half of the year.
