AIA study led by Google and BIDMC tested Google's diagnostic AI chatbot AMIE with 98 outpatients before emergency visits, with a supervising doctor monitoring every exchange. No conversation needed interruption under the predefined safety criteria, and clinicians said AI summaries helped them prepare for 75% of visits. AMIE's differential diagnoses matched final diagnoses 90% of the time, but the authors say larger trials are needed.

AIA Seed team preprint reports "phase sensitivity" in DeepSeek V4 and V4.1-Flash, where identical information becomes harder to retrieve depending on its position within compressed KV-cache blocks. The compression reduces memory and attention costs, but long-context retrieval accuracy varied by up to 40 percentage points across positions. The authors note that average benchmark scores can hide these recurring weak spots, though the findings concern retrieval specifically rather than all model behavior.

AIStar Motion Era's VPP2, a world action model, ranked first on the RoboDojo simulation leaderboard with a 32.26% average success rate and 39.26 average score. The article attributes gains to staged training that separates video prediction from action learning, and reports a 58.5% zero-shot success rate on a real ALOHA dual-arm robot versus 40% for π0.5. The code is open source on GitHub.

AIIn an urgent care study, physicians rated advice from the older Gemini 2.5 Pro and Gemini 2.5 Flash, which lacked access to patient medical records, as similar in quality to doctors' advice. No safety issues were identified. The author notes that models have improved significantly since.

AIByteDance Seed researchers found that language models compressing their KV cache in fixed-size chunks retrieve the same information unevenly depending on token position. In a 128K-token needle-in-a-haystack test, base DeepSeek-V4 checkpoints differed by up to 40.2 percentage points by phase, and post-training narrowed but did not eliminate the gaps. The authors urge evaluating such models across positional phases, since high average accuracy can hide systematic failures.

AISimplexity Robotics says it trained a single robot to load and unload two CNC lathes on its own, using 600 real-robot trajectories and reporting a 100% success rate on the precision CNC insertion task. The work, presented at IROS 2026 on September 29, combines the SimpleWAM world action model, a DRAM memory module and DPE action scoring, with force and torque feedback for insertion recovery. The company did not say how many trials the 100% figure covers, and it does not describe the yield of the whole cell.

AIMirroS released AgentGarten, which pairs executable code environments with a real-time neural renderer running above 30 fps so agents can act, observe, and learn. In a one-on-one hide-and-seek setup, the hider learned to block passages by round 4 and the seeker learned to climb ramps by round 10, guided by notes the agents wrote after each round. The authors report applying the same loop to four other tasks, including a dog-companion game, a narrow-bridge car passing task, herding, and quarry loading.

AITencent Hunyuan, with Fudan and Tsinghua researchers, released ExplorationBench, a benchmark that tests whether AI systems can discover rules through experiments in verifiable alien worlds. Across 10 frontier systems, feedback from experiments raised the best AlienCode score to 89.0% after four rounds, while closed-book runs without feedback stayed at 0.5–11.0%.

AIDonghua University researchers spun transistors, resistors and capacitors into a continuous fiber that functions as a circuit, using microfluidic encoded spinning, according to a Nature Electronics paper. The fibers integrated multicolor electroluminescence, analog and digital logic, and non-contact spatial sensing, and in demonstrations guided a robotic gripper and let a finger control a robotic arm and drone without touch.

AIA Chinese-led team published in Cell a three-dimensional spatiotemporal cell atlas covering rice from germinating seed to grain fill, along with a public portal and the RICE scGPT single-cell foundation model. The atlas combines single-nucleus RNA sequencing with BGI's Stereo-seq spatial transcriptomics across 10 organ and tissue types and 61 stages, defining 119 cell types and 133 subtypes.

AIOf 1,933 IROS 2026 papers, Robot Learning/Embodied AI appears in about 809, while Navigation/Planning covers 564 and Perception/Vision 556. The article argues large models are being embedded into traditional planning, geometry, and control rather than replacing them. Vision-language-action models are shifting toward efficiency, 3D understanding, memory, and system integration.

AIA paper introduces HERMES, a harness that pairs each repository component with a resident LLM and uses dependency-aware activation and failure diagnosis. With the same model and effort setting, GPT-5.6 Sol's whole-repository migration score rose from 6.5% to 31.0% when Codex was replaced by HERMES. Across four software engineering benchmarks, HERMES beats matched baseline harnesses by 12.4 points on average, and Qwen3-8B components come within 4.5 points of an all-GPT-5.6 Sol setup while cutting Terminal-Bench 4.0 inference cost by 26.2%.

AIOpenAI has published 722 math papers generated by an unreleased AI model, posted to GitHub, spanning about 20 mathematical subfields. The model did not fully prove the Riemann hypothesis but proved the quasi-Riemann hypothesis, and it also produced theoretical computer science and partial differential equation results. Many papers include Lean files for computer verification, and OpenAI plans to release more of them.

AIGoogle published a prospective study of AMIE, a research conversational system that patients chat with before doctor appointments, in The Lancet with Beth Israel Deaconess Medical Center. Clinicians reported the summaries helped them prepare for visits in 75% of cases and influenced their approach to care in more than half. AMIE's differential diagnoses matched the doctors' final diagnoses 90% of the time.

Why it matters: The study tests a patient-facing diagnostic chat system in a real urgent care clinic, a setting that goes beyond lab evaluation and is useful for judging clinical readiness.

AIA clinical trial found that nearly 100 patients discussed their symptoms with Google's AMIE chatbot before meeting physicians. The source text provides no further details on the trial's results or outcomes.

AIGoogle Research reports results from evaluating its research medical system AMIE in a real clinic with BIDMC, published in The Lancet. Across 100 patient interactions, AMIE recorded zero safety stops and matched doctor diagnoses in 90% of cases.

AIGoogle, in partnership with BIDMC Medicine, conducted a study demonstrating technology's potential to strengthen the relationship between doctors and patients. The post provides a link for more details but includes no further findings or figures.

AIGoogle reports that its medical research system AMIE, described as the first patient-facing conversational diagnostic tool of its kind studied prospectively in a real-world clinical setting, was evaluated in a study published in The Lancet. Patients who chatted with AMIE before in-person appointments reported stronger confidence and better organized thoughts. Physicians reviewing the pre-visit conversation information gained more time for collaborative care and shared decision-making instead of digging through data.

AIArtificial Analysis has added Grok Imagine Video 1.5 Lite to its AA-Video text-to-video leaderboards, including the AA-Video-T2V v2.0 and silent AA-Video-T2V-Silent v2.0 rankings. Readers can compare the model's results directly on those leaderboards or vote for it in the Video Arena.

AIArtificial Analysis reports that Grok Imagine Video 1.5 Lite comes closest to the frontier on AA-Video-T2V v2.0 in Multi-Scene & Narrative, Lighting & Materials, and Text Rendering. It is furthest behind in Dialogue & Lip Sync and Human Anatomy. Compared with Grok Imagine Video 1.5, Lite matches it in Physics and trails on the other nine capabilities, by the least in Multi-Scene & Narrative.

AIEpoch AI reports that GPT-6.1 Sol's latency behavior on long contexts suggests a change in how the model handles them, though not conclusively a new architecture. The post is a follow-up to its earlier report on latency scaling in frontier models.

AISara Hooker congratulated @weiyinko_ml for leading a new work on automated data quality control with agentic checklists. She linked a blog post from Adaption Labs with further details.

AIAn astrophysicist worked with Claude Science to create the first complete ultraviolet map of the sky, covering regions never observed in UV. Claude located existing datasets, combined them, and filled gaps with statistical inference, taking a few days rather than weeks of human work. The map is presented as a teaching tool and an example of low-priority scientific work that AI now makes feasible.

AIClaude Haiku 5.5 (High) debuted at #30 with 1587 points in Code Arena: WebDev, just outside the Pareto frontier. It matches GPT‑6 Luna's price at $0.10/$0.50 per 1M input/output tokens while scoring six points higher. Arena says it costs 90% less than Haiku 4.5 for +257 points, and 95% less than Sonnet 5.5 (High) for -128 points.

AIEpoch AI estimates the AI chips shipped through 2027 could support about 30 to 170 million concurrent frontier-model agents, or nearly 2 billion with cheaper models. Its researchers find the cost of a fixed level of AI performance has fallen about 47% per quarter over the past three years. The newsletter also reports China's semiconductor supply-chain exposure is 2.7 times that of the US.

AIStability AI's Interactive Research team introduced SemanTok, which makes early video tokens more semantically meaningful so the representation is easier to predict. According to the post, a model using SemanTok matches or beats the performance of a model more than three times its size. The approach targets more efficient autoregressive video generation.

AIGoogle Research is presenting ContinuousBench, a standardized benchmark for measuring knowledge transfer and data contamination in differentially private (DP) synthetic data generation. Alex Bie is giving an encore presentation at the Google booth #107 at COLM 2026 today, at 2:00 PM PT.

AIGoogle proposed FlowAgent, a ReAct-style agent that generates and validates fixes for pre-submit test failures and shows them in its code review tools. Two abstention filters, before and after execution, suppress weak suggestions; in a manual review of 195 real failures, 67.18% of fixes were correct. After the Google-wide launch, it suggested fixes on 295,508 changes, with developers previewing 65,069 and applying 28,554.

AIArtificial Analysis and Harvey released LAB-AA v1.1, which credits a legal task only when deliverables pass every rubric criterion with no material hallucinations. Grok 4.7 (xhigh) leads at 9.4%, ahead of Muse Spark 1.3 (max) at 8.9% and GPT-6 Astra (max) at 8.6%, while over 60% of otherwise passing results contained a material hallucination. The sharper reordering appears in the hallucination counts, where GPT-6 Astra averages 0.03 material hallucinations per task against 13.96 for Gemini 3.8 Flash (high).

AIThe Alzheimer's Translation Challenge is built on a new atlas of 150M cells, covering neurons, astrocytes, and microglia across different genetic backgrounds under combinatorial perturbations with multi-modal readouts. The data will be made available through the AD workbench and Prima Mente's modeling platform.

AIArtificial Analysis has released Harvey LAB-AA, an evaluation built on Harvey's LAB dataset and developed in collaboration with Harvey. Full results are published on the Artificial Analysis evaluations page, alongside Harvey's commentary on the benchmark and human expert preferences.

AIAmong models with a Hallucination-Gated All-Pass Rate above 0%, GPT-6 Luna (max), GPT-6.1 Sol (max), Muse Spark 1.3 (max), and Grok 4.7 (xhigh) set the Pareto frontier for score versus cost per task. GPT-6 Luna (max) is the cheapest at about $0.22 per task, scoring 3.3%, while Grok 4.7 (xhigh) leads at about $9.50 per task and Muse Spark 1.3 (max) costs about $4.20. The three Claude models cost about $18 to $22 per task.

AIOnce hallucinations are accounted for, Muse Spark 1.3 (max) drops from 26.7% to 8.9%, leaving Grok 4.7 (xhigh) first on the headline metric at 9.4%. Kimi K3 (max) falls from 16.7% to 5.3%, and Claude Sonnet 5.5 (max with fallback) falls from 11.7% to 2.8%. GPT-6.1 Sol (max) declines least, from 7.5% to 6.9%.

AIArtificial Analysis reports that Kimi K3 (max) achieves a 93.0% Criterion Pass Rate but averages 2.09 material hallucinations per task. Muse Spark 1.3 (max) scores higher at 96.0% while averaging 1.68 material hallucinations per task, showing that completing criteria and avoiding hallucinations are distinct skills.

AIArtificial Analysis compared six hallucination checkers on the same deliverables from 20 tasks across eight models. GPT-6 Sol and GPT-6 Luna generally flagged the most material hallucinations, while Claude Sonnet 5.5 and Gemini 3.8 Flash flagged far fewer, with Claude Opus 5.5 falling between Grok 4.7 and Sonnet. The counts reflect checker behavior rather than establishing accuracy or ruling out self-preference.

AIThe NVIDIA KGMON team placed second in the KDD Cup 2026 Data Agents competition with a system built around a smaller, clearer, and easier-to-verify agent harness. The competition required agents to answer natural-language questions over heterogeneous sources, including databases, CSV and JSON files, prose documents, PDFs, and briefing videos.

AIEpoch AI says it will expand its task suite, retire saturated tasks, and publish updated findings as new models are released. The announcement points to a full report by Kelly Hong on whether AI can automate tasks.

AIAn experiment by GPT-6 Astra examined why AI agents fail to learn with practice, finding that setting agents' token budgets too low prevented learning. The researchers reported this sensitivity to the acquisition budget as a key finding rather than an error.

AIWhen asked to propose a research project and pilot an experiment, models made simple setup mistakes but presented them as interesting findings. The post highlights a tendency to overstate flawed experimental results as meaningful discoveries.

AIEpoch AI says its evaluation tasks range from producing Epoch-style diagrams to designing basic research experiments. A human grader scores model outputs against the organization's internal quality standards.
