Google DeepMind Introduces Decoupled DiLoCo: An Asynchronous Training Architecture Achieving 88% Goodput Under High Hardware Failure Rates

⋅

Training frontier AI models is, at its core, a coordination problem. Thousands of chips must communicate with each other continuously, synchronizing every gradient update across the network. When one chip fails or even slows down, the entire training run can stall. As models scale toward hundreds of billions of parameters, that fragility becomes increasingly untenable. Google DeepMind is now proposing a different model entirely. Google DeepMind researchers introduced Decoupled DiLoCo (Distributed Low-Communication), a distributed training architecture that decouples […]

DeepSeek AI Releases DeepSeek-V4: Compressed Sparse Attention and Heavily Compressed Attention Enable One-Million-Token Contexts

⋅

DeepSeek-AI has released a preview version of the DeepSeek-V4 series: two Mixture-of-Experts (MoE) language models built around one core challenge making one-million-token context windows practical and affordable at inference time. The series consists of DeepSeek-V4-Pro, with 1.6T total parameters and 49B activated per token, and DeepSeek-V4-Flash, with 284B total parameters and 13B activated per token. Both models natively support a context length of one million tokens. DeepSeek-V4-Pro was pre-trained on 33T tokens and DeepSeek-V4-Flash on 32T tokens. Model […]

Human-machine teaming dives underwater

Human-machine teaming dives underwater

The electricity to an island goes out. To find the break in the underwater power cable, a ship pulls up the entire line or deploys remotely operated vehicles (ROVs) to traverse the line. But what if an autonomous underwater vehicle (AUV) could map the line and pinpoint the location of the fault for a diver to fix? Such underwater human-robot teaming is the focus of an MIT Lincoln Laboratory project funded through an internally administered R&D portfolio on […]

Artificial intelligence is already proving it can accelerate drug development and improve our understanding of disease. But to turn AI into novel treatments we need to get the latest, most powerful models into the hands of scientists. The problem is that most scientists aren’t machine-learning experts. Now the company OpenProtein.AI is helping scientists stay on the cutting edge of AI with a no-code platform that gives them access to powerful foundation models and a suite of tools for […]

Teaching AI models to say “I’m not sure”

Teaching AI models to say “I’m not sure”

Confidence is persuasive. In artificial intelligence systems, it is often misleading. Today’s most capable reasoning models share a trait with the loudest voice in the room: They deliver every answer with the same unshakable certainty, whether they’re right or guessing. Researchers at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have now traced that overconfidence to a specific flaw in how these models are trained, and developed a method that fixes it without giving up any accuracy. The […]

MIT scientists build the world’s largest collection of Olympiad-level math problems, and open it to everyone

⋅

Every year, the countries competing in the International Mathematical Olympiad (IMO) arrive with a booklet of their best, most original problems. Those booklets get shared among delegations, then quietly disappear. No one had ever collected them systematically, cleaned them, and made them available, not for AI researchers testing the limits of mathematical reasoning, and not for the students around the world training for these competitions largely on their own. Researchers at MIT’s Computer Science and Artificial Intelligence Laboratory […]

Europe—not US—first to authorize Moderna's combo mRNA flu-COVID vaccine

Europe—not US—first to authorize Moderna’s combo mRNA flu-COVID vaccine

⋅

Moderna’s mRNA-based combination vaccine against both flu and COVID-19 has gotten the green light in Europe—but it continues to be shelved in the US, where it was developed. This week, the European Commission authorized Moderna to market the vaccine, mRNA-1083 or mCOMBRIAX, making it the world’s first authorized combination shot for the two respiratory viruses. The decision follows a positive review in February from a key European Medicines Agency’s committee, which paved the way for the approval. Moderna […]
