Interactive Worlds And Physical Control

ABot-World-0 reports 720p world rollouts on one desktop GPU

Fan Jiang and 39 collaborators introduced ABot-World-0, an action-conditioned video model for scene roaming and third-person character interaction through raw keyboard input. Its training pipeline draws from games, simulation engines, and internet video, then applies 14 deterministic quality checks, vision-language assessment, and synchronized action and text labels.

The authors report that optimized low-bit versions stream 720p video at up to 16 FPS on an NVIDIA RTX 5090, with 1.2 seconds from an action to the first frame and about 19 GiB of peak VRAM. The paper describes long interactive rollouts and a memory mechanism for character appearance, but does not report a public player study or a shipping game loop with goals, scoring, and persistent rules.

Masked Visual Actions turns visible motion into a control interface

Hadi Alzayer, Wenlong Huang, Haonan Chen, and collaborators represent an action as a partially revealed trajectory inside a video. Showing a robot’s motion asks the model to predict how the scene responds. Showing the desired motion of an object asks the same model to generate robot behavior that could produce it.

The team fine-tuned one checkpoint with 15 hours of masked examples from real video and simulation. The project shows use on robot forms that were absent from training, planning by comparing candidate futures, and inverse modeling from desired object movement. Its failure cases include subtle contacts and artifacts around parts of an object that were hidden in the starting image.

IGGT4D follows geometry and object identity through a video stream

Zhengyu Zou and collaborators built a transformer that processes frames sequentially and updates camera motion, geometry, and object identity together. The accompanying InsScene4D-147K dataset contains real and synthetic, static and dynamic scenes with depth, camera poses, and object masks that remain linked over time.

The paper reports gains over streaming baselines on reconstruction, pose estimation, object tracking, and open-vocabulary segmentation. IGGT4D reconstructs observed scenes. Object behavior and responses to player input are outside its scope.

PhyParam exposes force, mass, friction, restitution, and gravity

Yanxun Li and collaborators created 130,000 simulated interaction videos with explicit physical parameters across five rigid-body motion types. Their image-to-video model binds force, mass, friction, and restitution to individual objects while also accepting scene-level gravity.

PhyParam-Bench scores temporal dynamics, spatial stability, and whether the generated motion agrees with the requested physical values. The authors report better physical consistency while maintaining visual quality. The published summary gives no aggregate improvement number; the authors say they plan to release the dataset, benchmark, and code.

Creator Tools And Visual Consistency

Appearance Pointers assign materials and identities to selected regions

Rahul Sajnani and collaborators introduced compact tokens that connect text or reference-image cues to user-drawn masks. The system is designed to place a material, object identity, or spatial instruction in the requested region without retraining the underlying diffusion transformer from scratch.

One model handles text and image guidance across multiple regions and reaches or exceeds the tested modality-specific methods across the paper’s metrics. Results are reported separately rather than as one combined score, and a production editor integration remains untested.

Vector-Bench separates a visible fix from an untouched document

Vector-Bench contains 40 SVG repair tasks. Each includes a corrupted program, a visual instruction, a hidden target, an average of 5.05 annotated repairs, and about 60.55 protected objects that should not change. Its evaluator checks both the requested repair and application-relevant SVG structure.

Across 34 model endpoints and 1,360 requests, the strongest endpoint achieved 15.0% full specification success despite 43.7% average repair progress. A vector image can therefore look partly repaired while the model has changed unrelated objects or code.

FlexiAvatar reconstructs only the body regions a camera actually sees

Yihalem Yimolal Tiruneh and collaborators avoid jointly optimizing body parts that never appeared in a monocular video. FlexiAvatar tracks the visible regions, adds part-specific detail, and uses diffusion-based completion for entirely unseen areas such as the back of a person.

Across full-body, partial-body, and head-only datasets, the ECCV 2026 paper reports an average PSNR improvement of about 3% over the tested methods. Restricting optimization to observed regions also reduces the number of 3D Gaussians processed in partial-visibility cases.

FilmWorld coordinates agents across a 15-novel benchmark

Jialong Zuo and collaborators divide novel-to-film generation into world construction and world evolution. One agent group turns prose into persistent entities and shot plans; another propagates entity state across generated shots and checks the result for consistency.

FilmEval uses 15 novels and nine automated metrics covering cinematic presentation, continuity, and fidelity to the source. The paper reports better results than the tested video-generation agent systems. Per-metric values and a human viewing study are needed to judge the size and perceptibility of those gains.

Developer Agents, Learning Tools, And Media Reasoning

CodeRescue chooses between another cheap attempt and escalation

Qijia He and collaborators treat an execution failure as new evidence for a coding agent. Their router chooses whether a cheaper model should attempt recovery or whether the task should move to a stronger model, then adjusts the cost penalty at deployment time without retraining.

Across failures from five coding benchmarks, one calibrated GPT-5.4-nano/GPT-5.4 setting exceeded the solve rate of always using the stronger model while spending 35% of its mean recovery cost. The guarantee controls expected cost under the paper’s exchangeability assumption; it does not guarantee a fix for each individual task.

AgentDebugX traces failures back to an earlier agent and step

Kunlun Zhu and collaborators built an open-source debugging loop that detects a failure, attributes its source, proposes a recovery, and reruns the task. Its multi-turn diagnosis examines the whole trajectory, investigates the execution structure, and cross-examines candidate causes.

On the Who and When benchmark, the best reported open-weight configuration reached 28.8% exact agent-and-step attribution, compared with 21.7% for the strongest single-pass baseline. On GAIA, it repaired 13 of 73 failed tasks in one rerun and raised overall accuracy from 55.8% to 63.6%.

EmbeddedKittens tests nine ways to represent Scratch programs

Benedikt Fein and Gordon Fraser compared four language models and five dedicated embedding approaches on Scratch token prediction and two classification tasks. Models trained on large public Scratch datasets captured enough structure and meaning to predict properties such as whether student programs were functionally correct.

The experiments focus on learning analytics in classroom-sized datasets without task-specific fine-tuning. They establish that Scratch embeddings can support these tasks, not that one method is best for every kind of program analysis.

OmniReasoner zooms into selected moments of long audio-video

Yu Chen and collaborators train an omnimodal model to begin with a low-cost preview, choose whether it needs more evidence, and call a tool for a denser view of a specific time interval. TimeAnchor keeps the requested interval consistent even when the preview and zoomed clip use different sampling rates.

The paper reports higher answer accuracy and temporal grounding across audio-video benchmarks while concentrating detailed processing on selected intervals. Model-by-model gains are not included in the published summary. The method answers questions about recorded media rather than controlling a live game scene.

Exhibitor booking is open, including a startup-area option, with no published closing date. The organizer has not announced individual visitor or convention ticket sales.
