    Attention to Mamba: A Recipe for Cross-Architecture Distillation

    Apple researchers propose a two-stage recipe for distilling a Transformer into a pure Mamba architecture without any Attention blocks. The method first distills a pretrained Transformer into a linearized Attention model via an adapted kernel trick, then distills that into an adapted Mamba model. The resulting distilled Mamba retains most of Pythia-1B's performance, reaching 14.01 perplexity versus the teacher's 13.86, with some gaps on tasks relying on in-context recall.

    SemiAnalysis releases GDPx benchmark for frontier agentic capabilities across high-value domains

    SemiAnalysis released GDPx, a benchmark covering chip design, cybersecurity, biology, finance, legal, quant trading, RSI, hardware design, materials science, alignment and software engineering, built with 14 specialized RL environment partners. Even the best model scores just 12%, with Opus 5.5 winning quant trading, hardware and chip design, Gemini 4 Carbon leading biology and software engineering, and GPT-6 Astra topping RSI and materials science. Every task runs in a realistic simulated environment, such as a ~4,000-file private equity deal room or live multi-service cyber ranges, unlike OpenAI's GDPval, which SemiAnalysis argues spoon-feeds context and lacks environments.

    Is Half of China's AI Compute Really Being Spent on Slop?

    A viral claim that 55% of China's AI tokens go to short dramas and video generation — traced to a June investor call by COL Group — has drawn rebuttals from ByteDance, which says video generation is only about 10% of its own compute, and from People's Daily. Over 90% of the roughly 430,000 micro-dramas released in the first eight months of 2026 were AI productions, and a five-second 720p clip on ByteDance's Seedance costs around 100,000 tokens.

    Google Research's sleep framework lets LLMs consolidate new knowledge without catastrophic forgetting

    Google Research introduced a sleep framework for continual learning that alternates active interaction with offline memory consolidation, letting LLMs absorb new facts into expanded Mixture-of-Experts parameters instead of losing prior knowledge. The approach combines parameter expansion, on-policy distillation with reinforcement learning-based imitation, and a dreaming stage that generates and filters synthetic training samples. The authors report near-zero performance drop in continual translation for unseen languages such as Manchu and Kalamang, near-perfect scaling to 10M tokens on BABILong, 48.9% single-task and 46.2% CPT results on SQuAD-based factual incorporation, and 79.2%, 69.0% and 46.1% on AIME 24/25 and HMMT 25.

    Ai2 study tests whether LLMs can reliably judge research idea novelty

    Ai2 released Old Ideas, Novel Problems, a study and benchmark testing how reliably LLMs evaluate the novelty of research ideas, along with data, code and a pipeline for building new evaluation sets. Across six judges including GPT-5.1, GPT-5.2, GPT-5.4, Claude Sonnet 4.5, Claude Opus 4.5 and Claude Opus 4.6, small prompt changes shifted accuracy by more than 50 percentage points on AI-generated ideas, and a simple prompted Claude Opus 4.6 baseline scored 0.854 macro-F1 at $2.59 versus 0.642 at $30.66 for Idea Novelty Checker and 0.772 at $82.05 for Sakana AI's AI Scientist.

    Redwood Research argues for accelerating AI's conceptual reasoning capabilities

    Redwood Research argues that AI's conceptual reasoning capabilities—tasks like philosophy that lack verifiable ground truth—should be accelerated differentially, since AI R&D and takeover rely far less on such reasoning. The team says basic elicitation techniques and small-scale training can make models three to twelve months better on its main conceptual reasoning benchmark, and that the area is currently neglected and underinvested by the AI safety community.

    Anthropic reports early progress on using Claude to accelerate drug development

    Anthropic's life sciences team has spent several months working with six drug developers, including Bristol Myers Squibb, Generate Biomedicines and Divergence Labs, plus running its own discovery programs, to test where Claude can speed up drug development. Reported early results include a Generate design roughly 70% shorter than the standard version that let immune cells make about 10 times as many receptors, and roughly 35,000 antibody designs generated largely autonomously for Divergence in about a month. Anthropic says the work is still mostly preclinical and plans to extend Claude into clinical trials as the programs advance.

    Why it matters: Anthropic's first detailed account of embedding Claude in real drug programs shows where the model helps and where it still falls short across six partners.

    Microsoft Research and co-author prove the 31-year-old KLS conjecture

    Microsoft researcher Xinzhi Zhang and a co-author have proved the Kannan-Lovász-Simonovits (KLS) conjecture, a 31-year-old open problem in high-dimensional geometry, showing the bound holds with a universal constant independent of dimension. The proof grew out of a human-directed agentic process in which AI agents explored more than 100 candidate approaches while researchers pruned and redirected the search, and a separate unguided attempt with leading models on a comparable token budget fell short. Two other proofs appeared the same day, and a Lean 4 formalization was subsequently released.

    Why it matters: A 31-year-old open problem in high-dimensional geometry is resolved through a human-directed agentic search over roughly 100 candidate approaches, with independent proofs and Lean formalization as confirmation.

    Mistral releases Timestral time-series foundation models, topping GIFT-Eval, TIME and fev-bench

    Mistral released Timestral, its first family of time-series foundation models, in four sizes from 5M to 209M parameters. The largest model ranks first on all three main public benchmarks, GIFT-Eval, TIME and fev-bench, among pre-trained zero-shot models from a single checkpoint without ensembling, using two-thirds of the parameters of the previous state of the art. Timestral produces probabilistic multivariate forecasts with 21 quantiles, supports past-only and known-future covariates, runs on CPU without a GPU, and is available through Mistral Forge for fine-tuning, with a GitHub repository and technical report published under a modified MIT licence.

    Why it matters: Mistral's first time-series foundation model family claims top zero-shot rankings on GIFT-Eval, TIME and fev-bench with a 209M-parameter checkpoint, offering a size-accuracy tradeoff reference for forecasting work.

    Goodfire research essay argues neural networks are already clean and superposition was misread

    Goodfire researcher argues that the canonical evidence for polysemanticity and superposition in neural networks was misread, and that what looked like arbitrary packing is mostly a motif he calls recursive generalization. Retraining InceptionV1 with ordinary architectural improvements and no change to model size or training data made 99-100% of neurons in its last layer easily interpretable, and preliminary audits of Qwen3-32B estimate roughly 90% of neuron poles have one main job. The essay concludes networks use one learning principle rather than two, so interpretability can proceed by studying neurons and circuits directly instead of first training decomposition models such as sparse autoencoders.

    Why it matters: A first-hand reinterpretation of the field's canonical polysemanticity evidence, arguing that networks generalize recursively rather than pack unrelated concepts, which would make direct mechanistic study viable.

    Modal tests mixed-precision, mixed-accelerator RL samplers on Qwen3.6-35B-A3B

    Modal trained Qwen3.6-35B-A3B on agentic coding with samplers spread across six accelerator types (B200, B300, H100, H200, A100, RTX PRO 6000) at NVFP4, FP8 and BF16 precision, feeding one BF16 trainer on B200. Plain GRPO collapsed on both mixed and homogeneous samplers, but adding masked importance sampling plus score centering, with or without top-p mask replay, trained stably to the end and reached SWE-bench Pro V2 pass@4 on par with homogeneous samplers, at roughly 15% lower sampler cost per update. The mixed samplers ran with an average sampler-trainer KL 4.7x that of the homogeneous setup, and the authors argue stability depends on keeping the mismatch bounded rather than low.

    Amazon Web Services researchers propose priming to convert pretrained Transformers into hybrid state space models without full retraining

    Amazon Web Services researchers introduce priming, a method that reuses pretrained Transformer weights to cut the pretraining cost of hybrid state space architectures by more than 99%, using under 0.5% of the source model's pretraining token budget. In controlled comparisons, Gated KalmaNet outperformed Gated DeltaNet and Mamba-2, and a 32B GKA-based hybrid matched its source Transformer on reasoning benchmarks while decoding up to twice as quickly at 128,000 tokens of context. The team released 8B and 32B primed hybrid models, training code, Triton kernels, and a vLLM serving plugin under the Apache 2.0 License.

    Why it matters: Amazon Web Services researchers show that reusing pretrained Transformer weights can cut hybrid architecture pretraining cost by over 99%, making controlled comparisons of state space layers practical.

    Epoch AI: Compute built over the next two years could run hundreds of millions of AI agents

    Epoch AI estimates that AI compute produced over the next two years could support tens to hundreds of millions of concurrent agents running today's most capable models, or billions running cheaper ones. Using projected HBM shipments from 2025 through 2027, the analysis counts GB300-equivalent GPUs and finds top-tier agents running nonstop could supply the weekly hours of roughly 140 million to 700 million full-time employees, while DeepSeek V4 Pro serving benchmarks imply about 1.9 billion concurrent agents. The report notes the key uncertainty is whether demand grows fast enough to justify the buildout or leaves a glut of agents.
