#032 - Novels and proofs: who gets the last word? | SynthAIcast
Saison 2 · Épisode 10
dimanche 8 novembre 2026 • Durée 10:37
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.

#031 - Discoveries and checkers: who checks the AI? | SynthAIcast
Saison 2 · Épisode 9
dimanche 1 novembre 2026 • Durée 10:59
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.

#030 - Agents and stores: who does your shopping? | SynthAIcast
Saison 2 · Épisode 8
dimanche 25 octobre 2026 • Durée 10:24
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?

#029 - Flood and filter: the AI music nobody hears | SynthAIcast
Saison 2 · Épisode 7
dimanche 18 octobre 2026 • Durée 10:46
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.

#028 - Watermark and key: who can read your AI text ? | SynthAIcast
Saison 2 · Épisode 6
dimanche 11 octobre 2026 • Durée 10:50
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.

#027 - Four months: who holds the door to AI ? | SynthAIcast
Saison 2 · Épisode 5
dimanche 4 octobre 2026 • Durée 10:28
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.

#026 - Four days: the labs, the rule and the door | SynthAIcast
Saison 2 · Épisode 4
dimanche 27 septembre 2026 • Durée 10:26
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.

#025 - Twenty-six percent: the measure and the measurer | SynthAIcast
Saison 2 · Épisode 3
dimanche 20 septembre 2026 • Durée 10:06
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.

#024 - Eleven days: three labs, one checkable proof | SynthAIcast
Saison 2 · Épisode 2
dimanche 13 septembre 2026 • Durée 10:29
Three labs proved something this week. Only one of them let the world check.
On Tuesday, an extraordinary claim, announced on a phone call with reporters. Eighty eight hours of compute, ten thousand agents. And a file that was never filed.
Two mathematicians had been working the same front for almost a year, out of their own research funds. What they published, anyone can verify.
Four days earlier, another lab had done the exact opposite. Eleven days of work, thirteen million lines, and the door left open.
On Friday, a one petabyte map of the human genome. The only result of the week an outside lab can test against its own patients.
And a commission of the French Academy of Sciences, in eighteen sixty four, where one of the two scientists refused to show up.

#023 - 12.9 billion, and who owns the roads of AI? | SynthAIcast
Saison 2 · Épisode 1
dimanche 6 septembre 2026 • Durée 10:11
We are handed models, tools, assistants. But which road do they travel on, and who owns it?
On Wednesday an agreement is signed. On Thursday it is made public. The warehouse where researchers and companies drop off their models changes hands.
The buyer makes the chips almost all of today's AI runs on. It promises, in writing, that its own chips will stay optional.
The same day, one lab decides on its own to cut a widely used tool off from its models. No judge, no regulator. One decision, one post, one date.
Then on Thursday morning, three assistants go down within the same half hour. One of them named its cause in two words, and they are exactly ours.
And a story from the nineteen fifties, where a plain metal box made the owner of the ship irrelevant. Then the ports changed hands.
This episode opens season two.
