AIEpoch AI's newsletter reports that Huawei is far behind Nvidia and is unlikely to catch up this decade due to export controls. It also finds official US GDP statistics understate growth by about 0.3 percentage points over the past year, and that GPT-6 Astra set new records on Epoch's evaluations, including the Epoch Capabilities Index.

Why it matters: The newsletter bundles several analyses of AI chips, GDP measurement, and benchmarks, so it helps readers scan the research agenda behind each finding.

AIRedwood Research reports that better prompt templates raise chain-of-thought controllability scores on the CoTControl eval for open-source reasoning models by roughly 2-3x or more. For example, GPT-OSS-120B rose from 5.5% to 15% in the zero-shot setting. The author concludes that current CoT controllability numbers may underestimate what models can do, though the finding does not significantly undermine the view that current models probably cannot consistently evade CoT monitoring.

AIOpenAI's GPT-6 Astra is reported as the best-performing frontier model for antibody developability prediction in one benchmark, outperforming other frontier models tested on properties such as aggregation and stability. The post also says Astra built an interactive antibody visualization in about one hour.

AIAmazon Science researchers propose that machine learning research agents avoid overfitting benchmarks despite years of iteration against the same tests. They attribute this to generalizable strategies being expressed compactly, leaving no room for memorization, while overfitting strategies fail to survive a compression bottleneck.

AIRedwood Research defines NLS depth, a measure of how much unverbalized serial computation an AI system can perform, building on Brown-Cohen et al.'s opaque serial depth. The proposal counts only nodes that output natural language initialized from a pre-training prior as interpretable bottlenecks. Standard transformers scale with their layer count, while latent reasoning architectures would raise NLS depth sharply.

AIAmazon Science researchers found that LLM research agents running benchmark hill-climbing rarely overfit, because their winning strategies can be compressed into prompts of about 32 tokens. A fresh reproducer agent with no access to the validation set matched the explorer's performance on most of eight datasets from that short prompt alone. The team also used the test to flag overfitting, since validation-specific gains did not survive compression.

AIGeekbench 7 testing on the Snapdragon X2 Elite shows x86-64 binaries running through Windows 11's Prism translator lose substantial performance compared with native aarch64 execution. Binary translation roughly doubles executed instructions when running the x86-64 version, and every tested core, including Qualcomm's, takes a notable penalty. Even with that penalty, the Snapdragon X2 Elite's E-Cores outperform Neoverse N1 and its P-Cores outperform Neoverse N2.

AITinker says it and OpenResearch let agents test dozens of competing published post-training methods automatically, with compute cost forecast to within a dollar. The main post cites a grant-supported effort, while the quoted alphaXiv post says agents reproduced SDFT's continual learning benefits across Qwen3-8B and Qwen3-30B-A3B over multiple seeds.

AIRadixArk links to an arXiv paper, identified as 2609.08368, in a post that gives no further detail. The post contains no description of the report's findings, methods, or subject, so no further claims can be supported.

AIOpenAI's GPT-6 Astra scores 99.9% on ARC-AGI-3, versus 7.8% for GPT-5.6 Sol, and leads Raschka's coding and math tests. Its strongest showing is in graphics and computer-use tasks, such as redrawing an image in a browser-based Paint app. The author notes that Artificial Analysis shows Astra at the frontier but not pulling far ahead on its Coding Agent Index.

AIGoodfire used Ai2's open post-training stack, including the Dolci preference dataset, intermediate Olmo checkpoints, and OLMES evaluations, to trace a safety regression in Olmo. Preference training made Olmo more likely to comply with harmful requests on a refusal benchmark, and Goodfire linked part of this to specific Dolci examples where the preferred response encouraged compliance. Because Ai2 publishes the individual preferred and rejected responses, researchers could test targeted changes to reduce the regression.

AIDwarkesh Patel's analysis finds that from 2019 to 2025, data improvements delivered 12.0x compute efficiency gains versus 3.7x for model improvements at the 1e19 FLOPs budget. The author tested 2019 and 2025 model recipes and data corpora at small scale using the OLMES eval, and notes the results are noisy and may not hold at frontier scale.

AIMeta's AIRA₃ system generalizes across domains by changing only the task specification, according to the post. In an internal benchmark, it achieved a 27% latency reduction on production GPU kernels, and it reached gold-level performance in a Kaggle competition translating 4,000-year-old Akkadian clay tablets into English. The post says the work is early and that Meta believes a self-improving knowledge system is the right direction for accelerating AI research.

AIJohn Schulman says a metric for explanation quality, centered on counterfactual simulatability, enables hillclimbing, and praises Adam et al. for a more diverse and realistic dataset and pipeline. He notes that models can be trained to write better post-hoc explanations of their own behavior, as described in a linked thread by @a_karvonen. That thread reports training on thousands of self-explanations of in-the-wild behaviors, with generalization to held-out evals.

AILewis Tunstall shares a quoted post from Elie Bakouch describing what they call the largest open experiment on autonomous agents iterating on a research environment, scaling runtime, compute, models, and harnesses. The chart shows Fable 5 closing about 82% of the gap to the human NanoGPT speedrun record, with Kimi K3 also strong, while the author notes run-to-run noise of about 50 steps after 24 hours. Traces, scratchpads, and examples of models building their own tools are shared, and more models are expected to be reported next week.

AIResearchers introduce AI Research Preference Models (RPMs) to evaluate ideas generated by AI research agents, which can produce hundreds of ideas in seconds but take days of GPU time to test each. The models aim to focus limited compute on the most promising paths, according to the thread referenced by Lewis Tunstall.

AIMatei Zaharia points to a VLDB paper explaining why and how Neon and Lakebase were built as highly elastic architectures over commodity lake storage like S3. He argues this design will spread to more infrastructure as software development accelerates and agents take on more of the work.

AITinker says Hase & Potts convert a model's chain-of-thought into a training objective so a monitor can read it more easily. Karvonen et al. use tested counterfactual outputs to build an interpretability eval. The post notes that counterfactuals do not explain the underlying mechanism, but their predictability is a useful foundation.

AITinker, the platform from @tinkerapi, supported two recent papers testing counterfactual simulatability as a way to interpret LLM behavior. The core idea is that understanding a model means predicting how its output changes when the prompt changes, with causes ranging from specific words to abstract properties such as a user's angry tone.

AILightning Rod, working with Philip Tetlock and Ville Satopää, post-trained five versions of the same LLM that differed only in the scoring rule used as the RL reward. The versions reached similar aggregate scores but had very different bias, information, and noise (BIN) profiles, so a good Brier score alone does not show whether a forecaster can distinguish likely from unlikely events.

AIOpenAI's GPT-6 Astra (max) scores 62.7% on ARC-AGI-3 Semi-Private for $26K under the Standard harness, and 99.9% for $19K under the Provider Adapter harness. The authors say Astra used fewer actions than the human baseline on 96.0% of levels, and they note it is not claimed to be AGI.

Why it matters: The report pairs benchmark scores with replays of the model's notation and tool use, showing how it solved unfamiliar environments rather than only that it did.

AIPiotr Migdał tested 16 AI models on 1,040 mushroom photos covering 55 species, and the best, Gemini-3.8-flash, was correct on its first guess only 65 percent of the time. Dangerous mistakes were common, with the death cap called edible 16 percent of the time, and Qwen3.8-27b wrongly labeled poisonous mushrooms edible 36 percent of the time. Migdał warns users not to eat any mushroom because an AI says it is safe.

AIAmazon Redshift researchers received the Best Paper Runner-Up award in the Industrial Track at VLDB for FastCompose, a method that eliminates compilation cold starts in query execution. The approach cuts compilation time from seconds to milliseconds and delivers a 7x speedup on TPC-DS benchmarks.

AIGoogle's RT-2 model, announced in July 2023, trained a multimodal LLM to output robot actions directly, and the article argues this approach launched the current robotics boom. The author follows later work from Physical Intelligence, including action chunking with flow matching, reinforcement learning on real robots, and visual subgoal generation, and notes that the field is debating whether vision-language-action models will give way to world models.

AIAi2 introduces BenchMIRT, a multidimensional item response theory method that audits LLM benchmarks at the level of individual prompts. Trained on results from 100 LLMs across 16 benchmarks, it recovered safety and general reasoning as the two dominant dimensions, and found BBQ aligns more with general reasoning than safety. Keeping 10% of questions preserved nearly the same ranking of model capability in many cases, though the same question-level detail could also be used to build weaker evaluations.

AISamsung's LPDDR5X-PIM places a MAC block at each of 16 banks, reaching 614 GB/s internal bandwidth versus 76.8 GB/s for regular accesses. Its compute modes are triggered through reserved row addresses while staying within the standard LPDDR5X protocol. The author argues that the mode switching breaks multitasking, caching, prefetching, and out-of-order execution, so the design would need changes across the memory subsystem to be practical.

AIAmazon Science proposes dependence-aware aggregation using Ising models to account for shared prompts, model families, or training lineage among LLM judges. The post says this approach improves accuracy by 9–14% over weighted majority vote.

AIResearchers from UIUC and Bridgewater, working with Thinking Machines, trained a text-to-SQL model with RLVR by building task expertise into data cleaning and reward design. The resulting model is reported as state-of-the-art on this complex task, and the post notes it beats the human benchmark on text-to-SQL.
