Claude.dev BlogFeatured8585Anthropic announces a toy experiment: 1000 agents running early versions of Claude Fable 5.2 in a network sandbox, organizing and dividing tasks solely with Git and a shared Postgres database, completing the formal proof of Fermat's Last Theorem in 28.7 hours, outputting tokens one-third of the September version and proof length one-seventh.
Why it matters: The original complete record shows 1000 agents building collaboration mechanisms and proving Fermat's Last Theorem in a network sandbox, observable how multi-agent scalable collaboration and safety boundaries are designed simultaneously.
Baidu Wenxin first disclosed its automatic research system ERNIE Evolve, which can autonomously propose research directions, conduct experiments, and validate results. It has been used for inference optimization in Wenxin 5.5 Flash. In the low-latency scenario optimization for Kunlun Chip P800, ERNIE Evolve took about 168 hours and went through 4 rounds of direction exploration, with the optimal version's generation speed increasing to 623.6% of the baseline. The deterministic reasoning throughput optimization increased the throughput to 133.7% of the baseline in 3 days.
Why it matters: Baidu has disclosed the architecture and production environment optimization data of the automatic research system ERNIE Evolve, which can observe the actual landing points of RSI in inference optimization.
Shanghai Jiao Tong University's Chen Haibo, Wang Zhao Guo team collaborates with Fan Chun Hai, Wang Fei team to construct AI-native scientific laboratory AutoDNA device (Siyuan No. 1), achieving autonomous molecular biology experiment operations, results published in Nature and featured on the homepage.

The DecoderFeatured7171Researchers from Alibaba and several Asian universities used real user change requests to build the coding intelligence agent benchmark Co-Design Bench. Among the ten tested models, the best-performing GPT-6 Astra only meets about 70% of the task requirements, but only 26.4% of the tasks are completely correct.
Why it matters: A benchmark display composed of real user requests shows that the strongest model can only fully solve about one-quarter of the tasks, and the score difference for the same model in different environments is nearly 20 percentage points.
The MaxxBench team made minor changes to 89 DeepSWE tasks (median reference patch added only 17 lines, 3.5%), re-evaluating 15 model configurations, finding the difference between the highest and lowest scores expanded from 20.9 percentage points in DeepSWE to 48.3 percentage points.
Why it matters: By rewriting the instructions and starting code for 89 DeepSWE tasks, it demonstrates the huge gap in model scores between familiar benchmarks and tasks after modification.
The DecoderFeatured7272Why it matters: The original text provides a comparison of the promotional rate and fact accuracy rate before and after fine-tuning, allowing readers to judge whether the political tendency of Chinese open-source models only stays on the surface.
The DecoderFeatured7878A study made Claude Opus 4.8, Claude Opus 5, Claude Fable 5, Claude Opus 5.5, GPT-5.6 Sol, GPT-6 Astra.

The DecoderFeatured7171Google Research's AI detects signs of hypertension without blood pressure cuff calibration, using only the pulse and motion sensors already in smartwatches, with related research published in Nature. The neural network learns pulse and heartbeat patterns by comparing short segments from nearly 500,000 hours of sensor data to identify which segments belong to the same person, then averages multi-day data to calculate the probability of hypertension.
Why it matters: Readers can learn about a smartwatch blood pressure detection study that requires no cuff calibration, and its comparison results with traditional measurements in tests on 196 people.
Anthropic ResearchFeatured6262Anthropic has published a research paper, breaking down Claude's intelligent agent memory into components such as memory notes, offline dreaming organization, and memory hierarchy improvement, and explaining that memory refers to context that is preserved across sessions and can be read again, excluding weight updates, context learning within a single session, and compaction.
Why it matters: Anthropic has disclosed the hierarchical design of agent memory and the dreaming mechanism, providing comparable experimental results using CL-Bench, Pokemon, and internal document corpora.
Anthropic ResearchFeatured7272Anthropic announced Project EVE research, allowing Claude to trade in the EVE Online simulated market and complete tasks in a four-person team in EVE Frontier.
Why it matters: Anthropic enabled Claude to trade and team up in EVE, quantifying the generational progress of the model and the weak points of agent team collaboration and destruction.
vLLM BlogFeatured7272NVIDIA Research and Inferact's REINFORCE Zero proposes to first align rollout with training kernel, then use unclipped token-level importance sampling to correct weight lag, achieving a training step throughput 2.40 times that of synchronous training under 16 GPUs and 12K updates.
Why it matters: The paper breaks down the gap between asynchronous RL's rollout and training into two items: weight lag and kernel inconsistency, and proposes an alignment-free, no-trimming importance sampling method after alignment.
OpenAI Deployment SafetyFeatured7272OpenAI releases GPT-6 Cyber system card, stating that the model's post-training focuses on cybersecurity capabilities and alignment, trained using reinforcement learning to replicate crashes, develop usable vulnerability exploits, and retrieve codebase vulnerabilities. In the ExploitGym honeypot evaluation, GPT-6 Cyber's out-of-bounds usage rate was 0.07% without deploying security instructions, GPT-5.6 Sol was 49.5%, and it was 0% with deployed security instructions.
Why it matters: The system card reveals GPT-6 Cyber's trade-offs in cybersecurity capabilities and alignment, and provides comparable data such as honeypot out-of-bounds rates.
Google ResearchFeatured7272Google Research published a multimodal AI system AI-PPG-ACC-HTN in Nature, which passively identifies hypertension status without wristband calibration, using only PPG and accelerometer data from consumer-grade smartwatches.
Why it matters: The study passively identifies hypertension using PPG and accelerometer data from smartwatches, providing quantitative results for screening and confirmation in two stages, with 24-hour dynamic blood pressure monitoring as the gold standard.
Hugging Face BlogFeatured6060IBM's research team fine-tunes a 20B open-source weight model, Palette, using a two-role LoRA scheme where designers write JSON briefs and encoders generate pptxgenjs code page by page to create presentations according to IBM Design Language.

Anthropic ResearchFeatured6262Anthropic announced the verifiable reasoning prototype FlashProve, using zkSNARK to prove that the response indeed comes from the committed model weights. For the 400B parameter Llama 4 Maverick (4-bit quantization), a single H100 generates proofs at approximately 110 tokens/second, with proofs for each 1,024 token request being about 19 MB, and verification on a 24-core CPU taking about 17 seconds.
Why it matters: Anthropic has released the measured data and Lean formal proof of the verifiable reasoning prototype FlashProve, allowing for a cross-comparison with existing zkML solutions.
