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.
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.
Venture capital firms are hitting pause on new investments, reports Lauren Goode at WIRED. The reason? Donald Trump's erratic trade policies have thrown Silicon Valley into a cold sweat.
Major VC firms pulled back nearly 40% of planned investments this quarter. First-time funding rounds took the biggest hit, dropping to their lowest level since 2019. Startups developing hardware or relying on Chinese manufacturing face particular scrutiny.
"We're seeing deals fall apart in real time," Sarah Chen tells WIRED. Her firm, Sequoia Capital, just shelved three late-stage investments worth $200 million combined. Hardware startups feel the squeeze most. A San Francisco-based robotics company had to slash its valuation by half after Trump threatened new semiconductor tariffs.
Even software companies can't escape the chaos. Cloud infrastructure costs could jump 15-25% if Trump's proposed tech tariffs take effect. For cash-burning startups, that's a potential death sentence.
Why this matters:
VCs have $290 billion in dry powder sitting on the sidelines – enough to fund the next Google or Facebook. But this money won't flow while trade policy looks like a game of darts played blindfolded.
When VCs get spooked, innovation suffers. Today's frozen funding could mean fewer breakthrough technologies tomorrow.
Three ex-Cisco executives raised $21M to build AI that handles system outages before engineers get woken up at 2 AM. Their secret: multi-agent systems that cut response time by 90%. But there's a catch that separates them from every other AI monitoring startup.
Perplexity AI, known for providing direct answers instead of traditional search links, is nearing a $14 billion valuation. Yet beneath the soaring numbers lies a pressing question: Can its novel approach truly reshape how we search the internet?
Benchmark just placed a massive bet on Chinese AI startup Manus, leading a $75 million funding round that values the company at half a billion dollars. Not bad for a startup whose AI agents sometimes crash while ordering takeout.
