Monroe Pretrains a Graph Model on 81 Million Molecules; Frozen Embeddings with TabPFN Outperform Per-Task Fine-Tuning

Monroe combines sparse graph attention, stereochemical edges, and 1,152 pretraining objectives, then uses TabPFN for in-context prediction on frozen molecular embeddings. It ranks in the statistically best-performing group across all 28 Polaris tasks, although its “100% win rate” includes ties in which it is not significantly different from the best method.

SPADE Has the Same LLM Write Executable Training Environments, Improving a 30B Model by an Average of 5.3 Points Across Eight Benchmarks

SPADE trains the environment designer using the return gap between runs with and without hints, allowing the curriculum to become harder automatically as the agent improves. Qwen3-30B-A3B gained as much as 13.9 points on tool-use benchmarks, though environment validators may still accept underspecified or unsolvable tasks.

VSPG Updates Discrete-Action Actors Without Backpropagation, Outperforming the DNN Baseline on Both SustainGym Benchmarks

VSPG stores each action as a unit hypervector, reformulating the softmax policy gradient as advantage-weighted vector superposition and normalization, without requiring automatic differentiation for the actor or optimizer state. It achieves higher returns and greater resilience to bit errors in two building-control climates, but performance depends heavily on the fixed encoder.

FM-Bench Has Agents Run a Football Club for 20 Years; None of 15 Models Could Infer Market Prices From Rejected Bids

Using 26 tools and roughly 340 to 400 decision points, FM-Bench tests whether agents can handle delayed rewards, hidden information, and competitors’ reactions. All 15 models completed the 20-year campaign, but rankings stabilized only in the later stages, while self-managed memory exhibited two failure modes: endless accumulation or repeated overwriting.

Attacking VLMs by Backpropagating Through the Vision Encoder Alone Cuts H100 Generation Time From Over 20 Minutes to About 100 Seconds

New research avoids backpropagating through the full multimodal model, instead modifying the input image so that the vision encoder’s representation diverges from the original image or approaches a specified target. Untargeted attack success rates exceeded 93% across four open VLMs, but the evaluation relies on a single LLM judge and does not test black-box transferability.

Recurrent Inference Improves Multi-Tool Composition, Raising the 1B Llama’s Average BFCL Score from 21.4 to 32.9

Researchers repeatedly update hidden states through the same set of Transformer layers before generating each token, comparing recurrent and conventional models using identical data and LoRA configurations. Gains are concentrated in parallel calls and cross-call dependencies, while API-Bank, which primarily involves single API calls, shows no consistent advantage.

VLA Monitors Hidden-State Communication Between Agents, Achieving 0.993 AUROC in Same-Model Auction Tests

A new study links continuous vectors exchanged between agents—but omitted from conversation logs—to their subsequent public actions as a single event, then applies three layers of checks: anomaly detection, counterfactual impact analysis, and sparse-feature inspection. The average AUROC of 0.993 combines text-based and latent-collusion samples, and the attacks were predesigned by the researchers, so the result cannot yet be considered a general capability for detecting emergent conspiracies.

Sonic-3.6 登上兩套人評語音榜首，官方延遲數字仍非端到端量測

Cartesia 推出支援逾40種語言的 Sonic-3.6，並在 Artificial Analysis 的供應商語音及受控語音榜取得首位。產品頁宣稱首段音訊延遲低於90毫秒，但公開資料尚不足以分離模型計算、網路及播放緩衝成本。

FACET Builds an Executable Environment Before Generating Terminal Tasks, Boosting the 9B Agent’s Score by 8.24 Points

FACET binds instructions, containers, reference solutions, and verifiers to the same execution state, synthesizing 6,078 verified tasks from more than 71,000 agent skills. Fine-tuned on just 1,200 successful trajectories, Qwen3.5-9B improved its Terminal-Bench 2.1 score from 27.34 to 35.58.

Across 1,338 Post-Training Trajectories, AI Agents Changed Strategy in Just 2.1% of Adjacent Experiments

The study finds that although agents can independently train, debug, and evaluate models, they lock in their training strategy before the first parameter update. Adding experiment logs, a skill library, and an evaluation agent improves downstream scores but still does not prompt systems to change approaches when the evidence turns against them.

Semantics-Preserving Rewrites Raise Coding Agent Costs by Up to 22.9%, While Robustness Rankings Flip Across Frameworks

Researchers applied control-flow rewrites, identifier renaming, and dead-code insertion to the same repair tasks, reducing solve rates by as much as 6.7 percentage points. Model robustness changed across mini-SWE agent, OpenCode, and datasets, meaning a single model leaderboard cannot predict deployment performance.

Cerebras CS-4 Combines Three WSE-3T Chips in a Rack-Scale System, Boosting Peak Bandwidth to 129.6 PB/s

Rather than moving to a new process node, the CS-4 increases the WSE-3’s clock speed, power delivery, and I/O, then combines three wafer-scale processors in a Nexus rack. Cerebras claims inference speeds of up to 30 times those of GPU-based systems, but its PFLOPS and throughput-per-watt figures still lack comparable independent end-to-end testing.
