⚖️ Ex-Meta engineer testifies against Zuckerberg LINK

Arturo Béjar, a former Meta engineer, testified against Mark Zuckerberg in an Oakland federal trial, telling jurors the culture the CEO built made it nearly impossible to fix safety problems on Facebook and Instagram.

Four state attorneys general, California, Colorado, Kentucky, and New Jersey, argue the apps were designed to hook minors, pointing to infinite scrolling, autoplay video, beauty filters, and the "like" button as harmful features.

Béjar said the safety tools Meta shipped were left as optional settings instead of defaults, so almost nobody used them, while the company denies misleading the public and disputes penalties it says could reach $1.4 trillion.

🤖 Robots' ChatGPT moment nears LINK

Unitree chief Wang Xingxing told Beijing's World Robot Conference that humanoid robots are nearing a "ChatGPT moment," yet warned the breakthrough could take two to three years if all goes well, or five to 10 years if it doesn't.

Wang defined the milestone as a robot dropped into an unfamiliar home, taking voice or text orders and finishing about 80% of tasks with no scene-specific training beforehand, a test he calls a tipping point for the field.

His caution follows Unitree's Shanghai listing, where shares jumped nearly sixfold before falling 11% the next day, even as Chinese makers shipped over 40,000 humanoids in early 2026 to buyers who are still mostly universities and research labs.

💬 Slack launches its own vibe coding tool LINK

Slack has rolled out Slack Code, a new "vibe coding" feature that lets teams work alongside AI coding agents inside group chats to build and fix software without waiting on a human engineer.

When someone tags an agent like Claude Code, Devin, or GitHub Copilot, it opens a new channel with the right people and context, then lets everyone watch it build and check an HTML preview before approval.

Available now on all Slack plans, the tool requires human sign-off for risky steps like merging code to production, and the agent automatically archives the channel once the team approves the finished work.

🔒 OpenAI spots misuse without reading prompts LINK

OpenAI is testing a service called Private Safety Processing that watches for misuse of its AI across multiple sessions while keeping none of a customer's data, giving select enterprise clients a privacy-focused way to catch abuse.

An automated agent looks at the inputs and outputs of several conversations at once, catching bad actors who spread requests over time, such as someone trying to build malware, without any person reading the actual chats.

If triggered, the system sends OpenAI a "narrowly defined signal" flagging the activity, and the company then decides whether to act and may contact the customer, who can choose to share data at their own discretion.

🖥️ Meta AI launches Mac app LINK

Meta has released a beta version of its Meta AI app for the Mac, built mainly for businesses and content creators, with links to Facebook and Instagram plus tools for tracking how posts perform.

The app can share a window during a session through screen capture to give advice on your work, offers dictation across all Mac apps, and connects to Google Workspace if you have a professional Facebook or Instagram account.

Meta AI is free, though Meta One plans raise the rate limits, and its privacy policy states that interactions with AI features are used to train Meta's models, so users may want to be careful.

🔧 Marvell to build AI chips for Google LINK

Marvell has agreed to supply custom AI chips to Google, and in return granted Google the right to buy up to $12.2 billion of Marvell shares, sending the chipmaker's stock up as much as 14 percent.

Google earns the right to buy nearly 59 million shares at $206.58 each by placing orders, with each $500 million of chip purchases unlocking more, a deal that could bring Marvell about $120 billion in sales through 2033.

The chips are parts that attach to Google's tensor processing units, such as inference accelerators and storage and networking controllers, adding Marvell as a second major supplier alongside Broadcom, whose stock fell around 5 percent.
