OpenAI

The most consequential courtroom drama in AI history kicked off today in an Oakland federal courthouse. Elon Musk — world’s richest person, OpenAI co-founder — versus Sam Altman, the CEO who turned that nonprofit research lab into an $850 billion juggernaut. Between them: a nine-person jury, thousands of pages of internal documents, and a question that could define how artificial intelligence is governed for decades. Opening arguments started this morning. This one’s going to be messy. ...

Three bombshells in 72 hours. OpenAI launched GPT-5.5. China’s DeepSeek dropped V4 at 85% less cost. Google committed $40 billion to Anthropic. The AI industry didn’t just shift — it lurched into a new phase where billion-dollar moves happen simultaneously and the gap between cutting-edge and affordable collapses faster than anyone predicted. GPT-5.5: The “Just Let It Work” Model OpenAI’s latest isn’t about raw intelligence gains. It’s about how the model works. ...

April 24, 2026 might be the most consequential single day in the AI model wars. Within hours of each other, two of the year’s most anticipated systems went live: DeepSeek’s V4 — an open-source behemoth running on Huawei chips with a million-token context window — and OpenAI’s GPT-5.5, which the company calls its “smartest and most intuitive model yet.” Neither was an incremental update. Both represent genuine leaps. And the fact that they dropped on the same day tells you everything about where this industry is right now. ...

Less than two months between GPT-5.4 and GPT-5.5. Even OpenAI president Greg Brockman admitted during Thursday’s press briefing that “there are probably enough model releases that it’s getting hard to distinguish one from another.” He’s right. But GPT-5.5 deserves your attention anyway — not because of what it promises, but because of what it reveals about where this industry is heading at full speed. The Pitch: Less Hand-Holding, More Doing OpenAI’s headline claim is deceptively simple: GPT-5.5 can do more with less guidance. Hand it a messy, multi-part problem and it figures out the plan on its own — choosing tools, checking its work, iterating toward a solution. ...

There’s a saying in venture capital: if you can’t pick the winner, fund the race. Amazon just applied that maxim with a $75 billion budget. Amazon announced it will invest up to $25 billion in Anthropic — the company behind Claude — as part of a sprawling deal committing Anthropic to spending over $100 billion on AWS over the next decade. This comes just two months after Amazon dropped $50 billion on OpenAI’s record-breaking funding round. ...

AI chipmaker Cerebras Systems just filed to go public on Nasdaq under ticker “CBRS.” The headline numbers look incredible: $510 million in revenue, a swing from a $485 million net loss to $87.9 million in net income, and $24.6 billion in remaining performance obligations. But buried in the S-1 is a financial arrangement so tangled it deserves far more scrutiny than it’s getting. OpenAI isn’t just Cerebras’s biggest customer. It’s also an investor, a lender, and the single reason this IPO is happening at all. ...

A new drug takes 10 to 15 years and roughly $2.6 billion to go from lab bench to pharmacy shelf. Most candidates fail. The process is brutal, expensive, and maddeningly slow — especially if you’re one of the millions of people waiting for a treatment that doesn’t exist yet. On April 16, 2026, OpenAI decided it wanted to fix that. The company launched GPT-Rosalind, its first AI model built specifically for life sciences research — and in doing so fired a shot directly at Google DeepMind’s long-standing dominance in AI-powered biology. Named after Rosalind Franklin, the scientist whose X-ray crystallography work was essential to discovering DNA’s double helix, this isn’t just another ChatGPT update. It’s OpenAI’s declaration that the future of drug discovery runs through AI. ...

The company building the machines that might replace your job now has ideas about how to make that transition less painful. Whether you trust the fox to design the henhouse security system is another question entirely. OpenAI dropped a 13-page policy paper called “Industrial Policy for the Intelligence Age” proposing four-day work weeks with no pay cuts, a public wealth fund giving every American a stake in AI growth, and shifting the tax burden from labor to capital — including potential “robot taxes.” ...

There’s something deeply uncomfortable about the timing. OpenAI is barreling toward what could be the most anticipated tech IPO in a decade — a valuation north of $1 trillion, 900 million weekly users, the kind of numbers that make Wall Street salivate. And right in the middle of that momentum, Florida’s attorney general just dropped a bomb. On April 9th, Florida AG James Uthmeier announced a formal investigation into OpenAI and ChatGPT, citing concerns about child safety, national security, and the chatbot’s alleged role in a mass shooting at Florida State University. Subpoenas are coming. The stakes couldn’t be higher. ...

Remember when ChatGPT just answered your questions without trying to sell you anything? Those days are officially over — and OpenAI is counting on it to the tune of $100 billion. OpenAI has told investors it expects $2.5 billion in advertising revenue this year, scaling to $100 billion by 2030. That’s building an ad business in four years that took Google and Meta decades to create. This isn’t some side experiment. This is the company that kicked off the AI revolution fundamentally reshaping how the internet makes money. ...
