Clearing up a robot’s fuzzy memory

In an emergency, a human might someday ask a robotic assistant to fetch a wall-mounted defibrillator located down the hall. But if the robot has incorrectly labeled the defibrillator as a fire extinguisher in its stored memory, it may not know where to find the life-saving device.This robotic assistant could benefit from a new memory

Tencent WeVisOne-VL Unifies Detection, OCR, Segmentation and Matting

Tencent’s WeChat Vision team has released WeVisOne-VL, an open vision language model in 2B and 4B sizes. The WeVisOne-VL vision language model handles detection, referring, counting, pointing, OCR, segmentation and alpha matting in one model. Pixel outputs come from a 9.6M-parameter decoder, so no separate SAM is needed. It also answers “None” when a queried

What Is Physical AI? A Complete Guide to AI in the Physical World

AI has become very good at working with information. It can write text, analyze documents, generate images, answer questions and help software make decisions. But the physical world is different. A warehouse doesn’t exist as a spreadsheet. A machine doesn’t exist as a database record. A delivery vehicle has to navigate an actual road. A

What Is Vision AI? A Complete Guide to AI Vision Systems

A camera can capture thousands of images every minute. But capturing an image is not the same as understanding it. A factory camera might see a product moving down a production line. A security camera might record activity around a restricted area. A retail camera might observe customer movement. A document scanner might capture an

Baidu Open-Sources Unlimited OCR 2 for Hundred-Page Document Parsing

Baidu has released Unlimited OCR 2, an open-source OCR model built for very long documents. The 3B model parses books, filings and reports of hundreds of pages in one request. Its core change is SR-SWA, a sparse attention scheme that keeps per-step decoding cost nearly flat. Weights ship under the MIT license, with code on

A Developer’s Guide to OmniParseBench: Leaderboard Benchmarks and OCR Testing

In this tutorial, we implement OmniParseBench, Datalab’s open benchmark for document parsers, which grades a parser’s output with 16,288 small pass-or-fail tests across 2,937 pages, from scanned forms and handwriting to arXiv math and dense tables. Rather than trust the leaderboard, we rebuild it from the verdicts Datalab released for 27 parsers, after feeding the

Why teaching AI about symmetry could make prenatal diagnosis more reliable

Despite millions of years of evolution, the development of the human fetus remains a complex process that is vulnerable to genetic, environmental, and metabolic disruptions. These disruptions could result in developmental abnormalities, starting with one of the first organs to begin developing in the fetus that continues to develop after birth: the brain.In a routine

Building a Streaming Robotics Learning Pipeline Using NVIDIA Cosmos3-DROID

In this tutorial, we design an end-to-end streaming robotics learning pipeline around the NVIDIA Cosmos3-DROID dataset without downloading its 707 GB repository locally. We first introspect the LeRobotDataset v3.0 structure and construct a metadata graph from info.json, task metadata, episode tables, and dataset statistics, then use HTTP byte-range access with PyArrow to selectively read Parquet

Datalab Introduces OmniExtractBench to Fix Bias and Opacity in Extraction Benchmarks

Datalab has released OmniExtractBench, an open benchmark for structured document extraction. It tests how accurately a system fills a JSON schema from a PDF. The benchmark pools 620 documents from 4 existing benchmarks. One deterministic scorer grades all of them and explains each decision. The release lands while extraction vendors publish their own leaderboards. Datalab

Nebius Opens 2026 Physical AI Awards: Five $150K Compute Credit Prizes

Once a physical AI product is in the field, the compute problem changes shape. Fleet data starts arriving faster than a team can label it, every retraining cycle has to be validated before it ships to hardware, and the sim-to-real loop stops being a research exercise and becomes a release process. That is the stage
