Universal Activation Bus aligns the intermediate representations of five language models into a fixed 3,072-dimensional space, requiring new models to train only their own linear encoder and decoder. In experiments, models could reuse the same probes, sparse autoencoder, and natural-language explainer, although representation reconstruction for wider models remained noticeably distorted.

Google separates low-latency conversation, in-depth clinical planning, and audiovisual perception into three asynchronous agents. Its overall score across 100 simulated video consultation scenarios exceeded the physician group’s 68%. However, the study used only trained patient actors, while the models, code, and audiovisual data have not been released, so the results cannot be directly extrapolated to real-world clinical deployment.

Peking University researchers have multimodal models interpret only the user’s operational intent, then use Text/Icon candidate detectors and a frozen CLIP model to select the click region. Accuracy on ScreenSpot-Pro rises from the strongest listed baseline’s 18.9% to 41.3%. The paper’s claim of being “regression-free” applies only to the final matching stage: the candidate-box detector still uses bounding-box regression losses, and no implementation has yet been released.
最新模型
Open-EA distilled multi-turn visual model evaluation trajectories into 10,042 supervised examples, moving a planning workflow that previously depended on GPT-4o to the local EA-3B model. The model, data construction pipeline, and runtime are now public, but the claim that evaluation time falls to 10% of traditional methods primarily comes from the original API-based agent and should not be interpreted as a general efficiency guarantee for EA-3B.

TIDE no longer treats high token-level agreement as direct evidence of successful distillation. Instead, it separately addresses student overgeneration and the omission of teacher-preferred tokens. Under the severe-mismatch setting, the method also reduces the average response length by 3.6×, although reproducing the full training run still requires eight GPUs and the authors have not released a checkpoint.
最新模型
Rather than replacing the quantizer, ICBQ jointly recalibrates the boundaries between adjacent Transformer blocks a second time, reducing the accumulation of early errors with depth. The quality improvement comes at the cost of a 21% average increase in quantization time, and the authors have not yet released an implementation.
AI 安全
ElasticBack hides malicious rules in `SKILL.md` and uses specific concepts in natural-language prompts as activation switches, without modifying model weights. Experiments show that the attack can evade multiple static and runtime checks, although false-trigger rates on Claude still reach 20% to 24%.

QueryProof delegates ambiguity detection, SQL allowlisting, and post-execution validation to deterministic rules, leaving only metric resolution and SQL drafting to the model. On an 80-question frozen test set, it outperformed a 32B baseline without the same rule-based wrapper, although the advantage’s confidence interval still crossed zero after resampling by task family.

Matryoshka Language Model Suites links 500M, 1.5B, and 3B submodels in a nested architecture that allows each model to be extracted and run independently, avoiding duplicate training for every size. Sharing early layers and the KV cache also increases speculative decoding throughput by 14% to 26%, though the approach has so far been validated only on base models up to 3B parameters.

P³ requires agents to agree on the implementation structure, helper lemmas, and proof decomposition before writing code, avoiding repeated proof patching after the program is complete. It outperformed comparison workflows across every model combination on three Lean 4 benchmarks, although the best solve rate on the hardest repository-level tasks was still only 22.2%.

ArchAgent v2 evolves L1D, L2, and LLC prefetchers in stages, using real-time capacity checks to eliminate candidates that exceed the hardware budget. The final design outperformed human champion BertiGO by 0.3% in the DPC4 simulation environment, but has not yet been validated on physical silicon.
推論系統
Tevatron-Elastic unifies early exit, Matryoshka vectors, and inter-layer token compression into configurable operating points, allowing one checkpoint to serve multiple cost profiles. In the authors’ test environment, the Qwen3‑0.6B reranker retained full quality at layer 16 while achieving a 1.75× speedup.
