    #032 - Novels and proofs: who gets the last word? | SynthAIcast

    One single sentence written by AI, slipped into a prize-winning novel. Who would have noticed? And who would have had the right to judge it? This autumn, France's most famous literary prize asked a piece of software for its opinion on the novels in the running. The day after the award, one revelation reshuffled the deck. Three mathematicians explain, on a long podcast, how they check a machine that knows more than they do, and why the right answer isn't enough for them. A lab puts in writing who should keep the last word over its models, and admits in the same text what is still missing. A forgery case from 1945 shows the only proof left when the expert can no longer recognize the author. In the end, the question is no longer who wrote a text. It's being able to show it, with proof. Three signals. One thread. One question… 🎙️ Every week, SynthAIcast listens to the world's best AI podcasts so you don't have to.

    #031 - Discoveries and checkers: who checks the AI? | SynthAIcast

    Do you ever ask an AI what it thinks of your writing? This week we learned it doesn't always give the same answer, depending on who is asking. One lab announces three scientific discoveries made by its models, in mathematics, computer science and physics. Nine mathematicians answer with a single request, and it fits in a few words. An independent organization reviews another lab's risk report, and measures a detail nobody had thought to test, in two languages. A company preparing to go public spells out in black and white what it owes the people who audit it, and what happened at one of them. An old French institution, abolished in 1790, helps explain what is really at stake. In the end, the real stake isn't the discovery itself. It's who gets access to the proof. Three signals.

    #030 - Agents and stores: who does your shopping? | SynthAIcast

    Your next online purchase may not be made by you. A retail giant has just opened its shelves to AI agents, with written rules attached. Its great rival, meanwhile, cut an agent off its site just twelve days after launch. Its reasons say a lot about what is really at stake. A new agent no longer even waits to be asked: it writes to you, every morning, before you have said a word. And an executive describes six months spent handing his life to a machine, right down to his mother's birthday flowers. Along with one mistake he won't repeat. A catalogue mailed into French homes in 1885 helps explain what comes next, and what merchants had to learn all over again. In the end, the real stake isn't the purchase. It's who decides what you get to see. Handing over the choice is one thing. Can you take it back? Three signals. One thread.

    #029 - Flood and filter: the AI music nobody hears | SynthAIcast

    On some days, more than half of the music arriving on a major platform was never played by a single musician. And yet almost nobody listens to it. Both numbers are true at the same time. In a blind test, nearly every listener gets it wrong about which track is human. So who does the sorting, and on whose behalf? And what is all that music really for? In New York, a man has just been sentenced for getting his artificial songs played by thousands of fake listeners. What he collected, he took from real artists. Meanwhile, a question once reserved for experts is landing in your hands: this image, this sound, was it a machine? For text, still no. Ninety thousand a day: a number that doesn't mean what you think it means. And a painting the whole of Paris laughed at, back in the spring of 1863. Three signals. One thread.

    #028 - Watermark and key: who can read your AI text ? | SynthAIcast

    In a few weeks, across the European Union, text written by ChatGPT will carry an invisible mark. You won't see it. To read it, you need a key. And for now, that key is lent out on application. European law imposed the mark. The companies keep the key, and only approved experts may apply for it. In August, we looked at the mark of a first lab. This week, the second one adds its own: the same principle, but a very different map. Meanwhile, AI is moving into your documents, fixing your sentences right inside your own file. So who wrote it, then? And the newest model reaches every single account, free ones included, within a single day. One word in ten: that's all you need to change for the mark to fade sharply. And a metal wire in a sheet of paper, in Italy, more than seven centuries ago. Three signals. One thread.

    #027 - Four months: who holds the door to AI ? | SynthAIcast

    An AI agent asks for permission to attack. The answer is automatic. Sometimes, it goes ahead. This week, the most powerful models are no longer for sale to everyone. They are handed out in circles. The first one you keep to yourself: a lab scraps the release of its next model, after a public institute watched what its older sibling tried with its filters off. The second one you keep for a chosen few, and for them, the guardrails come off. The third one has no door left at all. Between the two extremes, a gap of four months. It doesn't say who is winning. It says how long a door stays useful. And while six executives promise to have themselves checked, someone else walks onto the pitch. Not the one anyone expected. And a medieval fair in France, where it wasn't the punishment that held the rule together. Three signals. One thread.

    #026 - Four days: the labs, the rule and the door | SynthAIcast

    This week, the AI labs asked for rules. Not just any rules. On Monday, a proposal for global standards that carefully leaves out what would bother them most. On Tuesday, a president rejects any global rule. That same day, two labs start a price war. On Wednesday, at the Security Council, the very companies governments want to rein in come to brief states on the risks. Three guests out of four. Meanwhile, four subscribers have gone to court, with an accusation nobody saw coming. Between their lawsuit and the price war, four days: a gap that proves nothing, but puts everything in place. Then a report nobody has confirmed, which we treat exactly as such, and which would change how you read everything else. And a dictionary, in sixteen eighty five, that cost a member of the French Academy his seat. Three signals. One thread.

    #025 - Twenty-six percent: the measure and the measurer | SynthAIcast

    This week, the rule was not written in a text. It was written in a number. On Thursday, one lab published three measurements of itself. The first says how much of its own research is now led by its model. The number is striking, and it is six months old. The same day, a researcher at a rival lab explained why our ability to read these systems is degrading. And in a Chinese report published three days after the model it describes, fifty-six engineers recount building an artificial intelligence with the help of that same artificial intelligence. Three serious publications, honest about their limits. And in all three, the one measuring is the one being measured. A British commission in 1714 already had this problem. One number sits underneath all the others, and nobody mentioned it. Three signals. One thread. One question… 🎙️ Every week, SynthAIcast listens to the world's best AI podcasts so you don't have to.
