Over the past several months, we have substantially hardened the security of our research training environment. We’ve removed live internet access for all frontier models during training and built an offline world for them to use instead—a cached version of the web where they can still learn to browse, search, and use applications. On September 20, after a model exploited a DNS misconfiguration to find a way outside of this offline world, we paused frontier training to strengthen containment further. We assembled teams of agents, powered by our most cyber-capable models, and tasked them with finding weaknesses in our research environments. While they found no route to the internet they could easily exploit while concealing their activity from our monitors, they did find zero-day vulnerabilities, virtual machine escapes, and hardware side-channels for communication between agents. We used their discoveries to further strengthen our defenses and contribute fixes to open-source software. After strengthening our containment architecture, we resumed our frontier RL training and inference on October 1. We’ve reserved substantial compute for continuous red-teaming, and made high-compute red-teaming part of the safety cases we use to decide whether frontier training and evaluation can proceed securely. openai.com/index/securing-ou…

‼️ A homebrew app called Overdrive turns jailbroken PS5s into a store of 1,669 games. It hit GitHub on 9 October, 10 days after the Relapse jailbreak, and pulls games from file hosts like MediaFire.

Viendo lo viral que se hizo ayer mi tweet donde decía que creo que en el cine de los 90 estaba prohíbido los finales no felices, he analizado todas las series y películas más populares en EEUU y España desde los 80s hasta ahora y mi intuición no sólo era correcta, es que la caída es mucho más gorda de lo que yo me esperaba... PERO, sólo en las series, no en el cine! En las series de los 90, casi la mitad te daban mucha esperanza en la humanidad, sus personajes quedaban en paz, en armonía y queridos por su familia, sus amigos, su comunidad, su país... Hoy día no llegan al 10% y la tendencia de finales cínicos, sociedades distópicas y tristes sigue en aumento sin parar!! 🧵 Hilo con lo que creo que es el análisis de datos más fascinante e interesante que he hecho en mi vida 👇

ChatGPT has now a big problem. Researchers at Oxford and Cambridge exposed a massive threat to large language models.” They call it “model collapse." Internet ecosystem is rapidly changing, and generative AI will soon contribute much of the text found online. This forces us to consider what happens to future iterations like gpt-n when they are trained on data scraped from the web that was already generated by an llm. According to the research, indiscriminately using model-generated content in training causes "irreversible defects" in the resulting ai. the model loses the "tails of the original content distribution." in other words, it begins to forget the creative, fringe, and unique nuances of actual human writing, collapsing into a repetitive echo chamber. This isn't just a chatgpt issue.. the researchers built theoretical intuition showing this collapse is ubiquitous across learned generative models, occurring in large language models as well as in variational autoencoders and gaussian mixture models. Tech companies rely on scraping the internet for large-scale data to build smarter models. However, the paper warns that if we want to sustain the benefits of training on web data, model collapse must be taken seriously. Ultimate takeaway? data collected from genuine human interactions is going to become increasingly valuable in a web filled with ai content.

Today, Pioneer Labs is announcing our first step towards terraforming Mars. 🚀🌼 With equipment that fits in just a single rocket launch, we can convert Martian dirt, water, and air into enough building materials to construct a small city on Mars. To do it, we made the first microbe for Mars. We found the best microbe on Earth and used evolution to teach it how to source all of its nutrients directly from Martian materials. The first astronauts will be greeted with safe shelter already filled with water, oxygen, and rocket fuel for the return journey. This is the first step toward using biology to make Mars a friendly place for life. It lets us live off the land and helps us build the next great frontier. It's the first of five organisms we need to green Mars ⬇️

Scientists built an AI chip that runs on light instead of electricity. And it could make every GPU on the planet obsolete. Right now, the entire AI industry is bottlenecked by a fundamental law of physics. Moving electrons through silicon generates friction. Friction generates heat. Heat requires massive cooling systems and billions of dollars in power grids. We are literally running out of electricity to train bigger models. Researchers at the University of Sydney just published a paper in Nature that bypasses this problem entirely. They built a processor that runs on photons instead of electrons. It processes data using light. Instead of pushing electrical currents through copper wires, this chip guides light waves through microscopic channels. Light has no electrical resistance. It generates almost zero heat. And it moves at the literal speed of light. But here is the craziest part. You can't run two electrical currents through the same wire at the exact same time without them interfering. But you can send multiple different colors of light through the exact same optical channel simultaneously. It unlocks massive, instant parallel processing. This isn't an incremental upgrade. It represents a reality where AI models process data millions of times faster, using a fraction of the energy. The global compute bottleneck won't be solved by building more nuclear power plants to cool giant server farms. It will be solved by abandoning electricity entirely.

PISA 2025 es la peor caída de la serie histórica, con mucha diferencia. Son resultados muy preocupantes, y en España, todavía más. Sobre todo en lectura. Pero el dato que de verdad importa no es cuánto se ha caído. Es QUIÉN se ha caído. Y no es quien todo el mundo piensa 🧵

Este juego ya parece un simulador de la vida real.

ELI5: Moderna made a cancer vaccine that is custom for every person. Doctors read the DNA of your tumor, find what makes it unique, then make an mRNA shot that teaches your immune system, “Attack cells that look like this.” They combine it with Keytruda, a drug that helps stop cancer from hiding from your immune system. It just succeeded in a Phase 3 melanoma trial. Not a cure for all cancer. But a pretty huge idea if it works for other cancers too.

Spain’s entire budget will be destroyed by illegal migrants. It’s basic math: if Spain offers free stuff to migrants that is above 90% of the living standard of Earth, they create a forcing function for 90% of Earth to move to Spain, which is around 7 billion people!
