🧮 AI cracks 17-year-old quantum problem in 3 days
LINK
|
- Physics research company PSI says it resolved the Aaronson-Ambainis conjecture, an open question since 2008 about when quantum computers can beat classical ones, in just three days using an automated system.
- The system ran a non-public Anthropic model on PSI's own infrastructure, produced a proof accepted by the Lean proof-assistant, then improved it twice, with Lean accepting the final version.
- If it holds, the result shows a broad class of quantum algorithms can be classically simulated with only polynomial overhead, though the proof has not yet undergone full independent academic review beyond Stanford feedback.

🤖 Google expands TPU lineup to challenge Nvidia
LINK
|
- Google expanded its eighth-generation TPU lineup with two new systems, the TPU 8tx for confidential computing and the TPU 8i Max for memory-heavy workloads, pushing deeper into Nvidia's inference-accelerator territory.
- Both variants reuse existing silicon in new configurations: the 8tx keeps data and model weights encrypted during active processing and cuts latency up to 2x versus the TPU 8t, while the 8i Max packs two chips per package for double the compute, memory, and bandwidth in the same rack.
- Google also open-sourced TorchTPU so PyTorch code runs on TPUs with minimal changes, with vLLM and SGLang supported, as it courts nearly 100 external customers, though both new systems are repackaged silicon, not a new chip generation.

🇨🇳 Fine-tune cuts Qwen's propaganda to under 1%
LINK
|
- Nous Research released Arete-27B, a fine-tune of Alibaba's Qwen3.8-27B that strips Chinese state propaganda from the model's outputs, cutting its propaganda rate from 22 percent to under one percent while holding general capabilities steady.
- The team used supervised fine-tuning on about 53 million tokens over two epochs, no RL or preference optimization, lifting factual accuracy from 2.32 to 2.98 out of 5 and dropping free-speech propaganda from 60 percent to one percent.
- Weights, the 803-prompt test set, and training data ship under Apache 2.0 on Hugging Face, with Hermes Bench scores essentially flat at 65.60 versus 65.77 percent, though the reasoning-mode result of 3.07 rests on only two of five runs so far.

🔓 DeepMind's AI breaks old encryption 1,600x faster
LINK
|
- Google DeepMind's AI agents discovered cryptanalysis techniques that break legacy 1024-bit RSA signatures up to 1,600 times faster than prior methods, VP and Chief Scientist Pushmeet Kohli announced today, with modern 2048-bit and larger keys left unaffected.
- Working under human supervision, the agents found that once an attacker controls about half or more of a signed data block, RSA-1024 padding adds virtually no protection, making forgery as easy as attacking an unpadded system.
- A second result cuts the average cost of batch-factoring each additional 1024-bit key by roughly 30 times, a tool for stress-testing future systems, though the findings pose no threat to encryption securing banking, messaging, or digital currencies.
