✍️ WhatsApp's new AI helps you rephrase messages

📈 TikTok parent overtakes Meta in revenue

• In the first quarter of 2025, ByteDance's revenue climbed to over $43 billion, surpassing Meta’s $42.3 billion and making it the world’s largest social media company by revenue.

• The company's second-quarter revenue also grew 25 percent year-on-year to approximately $48 billion, with most of the increase driven by strong performance in its home market in China.

• ByteDance is starting a huge stock buyback that values the company at more than $330 billion, funding the program from its balance sheet while boosting its share price for employees.

🛡️ OpenAI and Anthropic test each other's AI for safety

• OpenAI and Anthropic, two major AI rivals, agreed to evaluate the safety and alignment of each other’s publicly available systems and then shared the results from their analyses.

• Anthropic’s review raised concerns about potential misuse with the GPT-4o and GPT-4.1 models and also identified sycophancy as a problem in most of the systems it tested.

• OpenAI's analysis showed Anthropic's Claude models performed well in instruction hierarchy tests and had a high refusal rate in hallucination tests, meaning they avoided offering answers when uncertain.

⚠️ Apple warns UK against new tech regulation

• Apple warns the UK that its proposed regulations mirror the EU's Digital Markets Act, a policy it says delays features and is ultimately bad for both users and app makers.

• The company claims that demands for "interoperability" compel access to sensitive user data and intellectual property, which undermines the privacy and security protections people have come to expect.

• The CMA counters that its UK-specific plan differs from the EU's and will let developers "steer" payments to other systems and innovate without introducing new risks for consumers.

✂️ Google has cut 35% of small team managers

• Google confirmed it has cut 35 percent of managers overseeing small teams compared to last year, aiming to have fewer leaders spread across much larger groups of employees.

• Many managers whose positions were eliminated remain at the company, having been moved into different roles where they now work as individual contributors instead of supervising other staff.

• The move is part of a wider efficiency plan that includes voluntary exit programs offered across ten units, which between 3 and 5 percent of employees have accepted this year.

✍️ WhatsApp's new AI helps you rephrase messages

• WhatsApp's new "Writing Help" feature uses AI to suggest rephrased, proofread, or tonally adjusted versions of your messages, offering options like professional, funny, or supportive text.

• The tool runs on "Meta’s Private Processing technology," which means Meta and WhatsApp cannot read your original message or the AI-generated rewrites, keeping your conversations private.

• You can access these suggestions by tapping a new pencil icon that appears when writing a message, which then shows different options for how to phrase your text.

💸 Nvidia is (really) profiting from the AI boom

• Nvidia’s revenue jumped 56 percent to $46.7 billion for its second quarter, which is the ninth straight period where year-on-year income has increased by over 50 percent.

• Sales for the new Blackwell-based chips reached $27 billion this quarter, a product line that now accounts for 50 percent of the company’s entire data center revenue.

• Despite the US blocking H20 chip shipments, Nvidia is developing a more advanced chip for China based on its Blackwell architecture, which could lead to another leap in sales.
