Make anything with Claude Fable 5.2 and Sunra MCP. One sentence and Fable 5.2 built the whole dinosaur park: 24 assets, from the T-rex and the jeep to the watchtower and the flare gun. → Anthropic's most capable widely available model → One sentence in, a whole world planned out → Up to 30% faster than Fable 5.1 → Images, video, audio and 3D, saved to your Sunra project

Anthropic engineer: “99% of people use Claude Code like Google, and only 1% are running swarms of self-learning Claude agents. I’m running 100+ agents in a loop. I have a Chief agent, PM agents, they manage the whole team.” In a 30-minute workshop, an Anthropic engineer revealed how to get the most value out of Claude Code at the lowest cost. This is worth more than another $500 course.

f*cking insane. i gave Claude Fable 5.2 one job: "build me an app i can charge for." then gave another AI one rule: "break it before my first customer pays." my test case: a booking app. pick a slot, pay, get a confirmation. easy when i'm the only person clicking. now two people want the last slot. one pays, the confirmation never arrives, and they hit retry. what just happened to their money? the part worth stealing: write down what must stay true BEFORE asking AI to find bugs. for this app: → one slot can only belong to one confirmed buyer → retrying a payment must never charge twice → a successful payment must end in a booking or a refund then give your coding agent this: "Turn these rules into a test plan. Try to violate each one with simultaneous users, lost responses and retries. For every scenario, show the exact steps and what should happen." that second AI is @brekenai. Fable builds the app. Breken runs the actual software in an isolated environment, fills it with synthetic users and agents, and introduces the failures your happy-path demo never sees. when it confirms a bug, you get the exact sequence that caused it and a draft fix to review. something you can reproduce, fix and test again before a paying customer hits it. that's the loop: try to break a rule → reproduce the failure → review the fix → run the same scenario again → decide what ships honestly the replay is what i'd pay for. i want to see the SAME checkout that failed survive after the fix. a fresh demo where nobody hits retry tells me nothing. i want the app to have its worst day while every customer is still fake. steal the prompt for your own app. then put it through Breken before your paying customers become the test team. their launch is below ↓

green CI, red production. most tools check what your team thought to test. Breken does the opposite: → rebuilds your real software on its own machines → throws users, months of data and dying services at it → finds the bug a customer would've found first tests prove you guessed right. production doesn't care

People don't understand how insanely high IQ Newton was. By age 20, he had no training in math or algebra and in <3ys he studied Euclid, Descartes, Kepler, etc., then laid the groundwork for the laws of motion & gravity, invented calculus, and the theory of colors & light. All while working alone on a little farm outside town. There's a great clip of Neil deGrasse Tyson explaining how there's no contest as to why Newton was the greatest scientific mind ever produced. In art, there is no target or framework to go about creating something. Only da Vinci could've painted The Last Supper, Homer written The Iliad, or Beethoven composed the Fifth Symphony. No other human being could've produced those pieces of art. Creative work has no boundaries and can't be pinned down or analyzed. Science is different. In science, you need to know what questions to ask because the work you can do is deterministic, in a sense. You try to fill a piece of the puzzle that already exists, and nature dictates whether something is true or not. In science, which threads you pull is just as important as the work itself, if not more. Someone would've eventually done what Newton did because the pieces are predetermined. However, in 1,000s of years and likely 100s thereafter, only Newton figured it out. And it was because of the questions he was after + his extreme intelligence. For ex, in the 1680s, Halley was trying to understand what motion an inverse-square law would produce. No one had the answer, so he consulted Newton, and Newton said: "An ellipse." Halley asked how he knew that, and Newton's reply was sth like: "Oh, I proved it years ago." The guy had used the math he'd developed to answer it. At the end of Newton's book on Opticks, he includes his unresolved Queries and other topics that interested him. It's astounding because he framed questions in a way that gave away his intuitions. Not only were the questions 100-200 years ahead of his time, but his guesses would prove largely right. He really was someone who thought extremely hard about everything and paired the thinking with rigorous experimentation. “I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.” - Newton

Un estudiante de 19 años gano 9.000$ en 1 minuto desde su residencia. Sin equipo. Sin agencia. Sin suscripciones. Hasta hace un mes, hacer una campaña con IA significaba tener 4 pestañas abiertas. Una para la imagen. Otra para el vídeo. Otra para el audio. Otra para el guion. Y una suscripción distinta en cada una. Él las cerró todas con Sunra. Conectó Sunra MCP a Claude. Le pidió: “hazme 3 variantes del póster de lanzamiento y un clip de 8 segundos de un taxi bajo la lluvia”. Claude buscó el modelo adecuado, miró qué parámetros necesitaba y lanzó la generación. Antes de gastar nada, le dijo cuánto iba a costar y le pidió confirmación. Imagen, vídeo, audio y 3D. Desde el mismo chat donde escribía el guion. Y aquí está lo bueno: cada modelo se cobra a precio de la API original. Sin recargo. Una cuenta. Un saldo. Todos los modelos. La mayoría sigue saltando de pestaña en pestaña. Él dejó de cambiar de herramienta. Empezó a crear. La única pregunta es por qué todavía no eres tú
Today we're launching Sunra Enterprise, with team plans up to 56% off API prices. One workspace for your whole team, with every leading model, a shared credit pool, admin controls and priority support. Don't fly solo. Bring the whole crew.

🚨 ¿ENTIENDES LO QUE ACABA DE HACER POSTIZ? Todo internet lleva meses culpando a los agentes de IA de llenar las redes de bots. Comentarios clonados, posts falsos, cuentas que no son de nadie. Y Postiz, una de las herramientas que conecta agentes de IA con más de 30 redes, ha sacado una película acusándose a sí misma. En el corto: * un tío entierra internet en un cementerio porque ya no queda gente real * un negocio gestionado por agentes acaba vendiéndole todo a bots * la gente se organiza para entrar en la sede de Postiz y "salvar internet" Está hecho entero con IA y parece cine. El final no lo vas a ver venir.
The internet is dead — it's official 💀 Internet, I loved you ❤️ Today, bots create all the content online: posts, comments, skits, ads none of it is real anymore. And no human wants to interact with it. There are no jobs now. We are all poor.
