1. OpenAI enters custom AI chip race with Jalapeño, developed with Broadcom
In just 9 months, the chip went from design to manufacturing tape-out.
OpenAI’s models aided development.
~50% lower cost than typical AI GPUs, Broadcom CEO Hock Tan said.
Later this year, the finalized chips will be integrated into Microsoft and other partners’ data centers.
OpenAI is currently testing the silicon on AI workloads.
Broadcom stock rose marginally on the announcement
Separately, OpenAI updated GPT-5.5 Instant with better intent understanding, more reliable responses, and improved shopping recommendations.
Looking for an AI notetaker for your meetings?
Granola is a lot more.
Most AI note-takers just transcribe what was said and send you a summary after the call.
Granola is an AI notepad. And that difference matters.
You start with a clean, simple notepad. You jot down what matters to you and, in the background, Granola transcribes the meeting.
When the meeting ends, Granola uses your notes to generate clearer summaries, action items, and next steps, all from your point of view.
Then comes the powerful part: you can chat with your notes. Use Recipes (pre-made prompts) to write follow-up emails, pull out decisions, prep for your next meeting, or turn conversations into real work in seconds.
Think of it as a super-smart notes app that actually understands your meetings.

3. Anthropic said to accuse Alibaba of adversarial Claude distillation

Alibaba allegedly used ~25K fraudulent accounts for 28.8M Claude exchanges between Apr.-Jun., according to Anthropic’s letter to U.S. officials.
Anthropic called it the biggest known attempt by a Chinese company to piggyback on leading U.S. AI labs.
Alibaba and other Chinese firms are making systematic, unauthorized use of top U.S. models, Anthropic said.
Alibaba stock -5% following the news.
The best investors know small problems compound fast. Eye bags and tired skin are no different. You need to address them early, before they become the new normal.
That’s why Particle Anti-Aging Face Cream sold out so quickly once founders and investors discovered it. More than 1 million men now use it to combat eye bags, wrinkles, and dark spots. The 6-in-1 formula combines 12 high-grade ingredients in a single anti-aging solution built for men.
If you want that sharper, younger look that signals energy, discipline, and confidence, this is the move. Bay Area Times readers: Use code BAY20 for 20% off and free shipping before it sells out again.
