AI models typically learn by memorizing patterns, then researchers bolt on reasoning as an afterthought. A new method called Reinforcement Pre-Training flips this approach—teaching models to think during basic training instead.
Good Morning from San Francisco, Meta's AI app turned users into accidental exhibitionists. 😬 People shared medical questions, legal
Meta users think they're chatting privately with AI. Instead, they're broadcasting medical questions, legal troubles, and relationship problems to the world through a public feed that many don't realize exists.
In 2022, Notion's founders skipped their company offsite. Instead, they locked themselves in a room with OpenAI's latest AI models. One week later, they emerged with something that would transform their company: a working AI assistant that could actually write.
Talk about a productive week off. The gamble worked. Within weeks, two million people jumped on the waitlist for Notion AI. Users now save over 70 minutes weekly through automated summaries and content generation. The company has morphed from a simple note-taking app into what co-founder Akshay Kothari calls their users' "second brain."
But this isn't your typical Silicon Valley AI publicity stunt. Notion rebuilt their entire platform around OpenAI's technology, integrating GPT-4 and other models into every corner of the workspace. The result? A system that doesn't just store information – it helps you use it.
The transformation runs deep. Notion's engineering team can now evaluate new AI models in half a day. Their Q&A feature lets users interrogate their entire workspace like a knowledgeable colleague. Response times have dropped from minutes to milliseconds.
The numbers tell a compelling story. Two-thirds of AI feature adopters become more active users. A whopping 86% would be "very disappointed" if the AI features vanished. Translation: they've become essential tools, not just fancy add-ons.
The partnership between Notion and OpenAI has evolved beyond a simple vendor relationship. They've shaped each other's development, with Notion's real-world feedback influencing OpenAI's technical roadmap. It's less David and Goliath, more Rogers and Hammerstein – if they wrote code instead of musicals.
The future looks ambitious. Notion aims to transform their AI from a writing assistant into something closer to a chief of staff – a digital partner that helps users "operate at the top of their game." Given their track record, they might just pull it off.
Why this matters:
Read on, my dear:
DeepSeek released an AI update without fanfare that now ranks just behind OpenAI's best models. The Chinese startup's quiet approach achieved what billion-dollar marketing campaigns couldn't: performance gains that forced competitors to cut prices.
A former AI researcher left his Munich lab to chase what he calls the "holy grail" of artificial intelligence. His startup just raised $13 million with barely more than a demo video. What convinced investors to bet big on something that doesn't exist yet?
The Servo browser project reached a turning point by successfully displaying Gmail in test mode. Beyond its technical achievement, this advance signals a shift in how web browsers could evolve—and who controls them.
Anthropic's latest API update promises to revolutionize how businesses access real-time data through AI. But behind the $10-per-thousand-searches price tag lies a strategic gambit that's already reshaping the industry.
