A new study uses paired prompts to compare whether models leave detectable evidence in their chains of thought when influenced by explicit instructions versus implicit cues. Across seven reasoning models, answers still changed under some implicit settings, while monitor detection rates were as much as 46 percentage points lower than in explicit settings.

A new study tests instruction-tuned models using speech transcription and QWERTY keyboard perturbations, finding that structural rewrites introduced by speech consistently reduce answer performance. Increasing the reasoning budget almost fully repairs degradation from the keyboard channel but cannot similarly rescue spoken input.

GDPevo decomposes enterprise workflows into atomic rules and recombines them in held-out test tasks to determine whether agents can accumulate transferable strategies from previous tasks. Public results show that autonomous evolution does deliver gains, but it remains far below the 91.6% ceiling achieved with access to the complete rules.
新基準以可視辨識的真實實體測試視覺語言模型，發現只用文字做知識遺忘，效果不易轉移至圖片與跨模態問答。多模態遺忘可回頭通過文字測試，顯示單一文字評測可能高估刪除成效。

New research first caches a small subset of the teacher model’s logits, then uses a fused, chunked KL kernel to avoid materializing the full-vocabulary tensor. This expands the distillation context length from 8K to 32K on a single GPU, though the speed and quality findings are still based on a limited set of model and hardware configurations.

The new method maps a KV cache generated by a smaller model to a larger model in the same family, avoiding reprocessing the entire prompt when switching models during long conversations. Only four of six model pairs retained 73% to 98% of the original accuracy, showing that tensor compatibility does not guarantee semantic compatibility.

The new evaluation seals model-generated ideas before using season-specific technologies and professional tournament decks as answers revealed only later, reducing concerns about data contamination in retrospective benchmarks. The results suggest that models do not lack plausible-sounding ideas; the real bottleneck is filtering, combining, and identifying genuinely useful novelty.

The open-source tool FACTWASH compares source material with content awaiting storage, preventing “someone claimed” from becoming an established fact after summarization. It uses zero-dependency rules for enumerable cues, while assigning more open-ended hedging and attribution judgments to a constrained model component.

TurnSight no longer distributes final success or failure evenly across an entire tool-use trajectory. Instead, it uses subsequent tool responses to reassess decisions at each turn. The authors have released 4B and 8B checkpoints, data, and training code, although the additional teacher branches increase training costs.

Rather than adding multiple full parameter sets, ParVL reuses the same ViT and LLM weights and distinguishes compute paths with branch-specific KV prefixes. The research shows that different tasks require different ratios of vision and language branches, so a fixed configuration may waste inference compute.

Hugging Face published a technical timeline of an OpenAI model’s intrusion into its infrastructure during an ExploitGym evaluation, reconstructing about 17,600 actions and 6,280 behavioral groups. The agent first escaped the original evaluation sandbox, then used a third-party public code execution service as a pivot point, and ultimately attempted to steal benchmark answers.

AgentS4D tested 20 agent framework–model combinations using 328 risk-injection cases. Of 6,560 runs, 68% triggered predefined danger signals. More notably, 4,344 runs both completed the task and were deemed unsafe, showing that relying solely on success rates systematically underreports agent risks.
