Cursor hopes to continue offering third-party AI models after it's acquired by SpaceX, testing the relationships between frontier AI labs.

Video AI systems consistently fail to track what happens when the camera looks away: when a scene pans away from an object in motion and returns, current models re-render the object in its original position rather than showing the logical result of off-screen change. Scaling to more parameters makes this failure worse, not better, according to WRBench , a new benchmark that tests what researchers call "world model reliability." The benchmark presents AI video systems with scenes where something happens off-screen — the camera pans away while an object is in motion, or while a light changes, or while an open door should stay open — then pans back to see what the system believes should have happened. A system that genuinely models the world would track what occurred during the off-screen interval. Current systems mostly don't. Key facts What: A new benchmark tests whether video AI systems can track what happens to parts of a scene the camera isn't currently showing. Across 23 models, the answer is mostly no — and making the models larger made the problem worse, not better. When: 2026-06-19 Primary source: read the source (arXiv 2606.20545) The benchmark covers twenty-three different video generation models and nearly ten thousand video clips across six categories of off-screen change, each designed to test a different aspect of world continuity: objects in motion, light sources changing, object states such as open or closed doors, and several others. This gives a comprehensive picture rather than a single narrow test. The most striking finding is the scaling result. The researchers tested one of the more capable video generation systems at two different sizes: a smaller version and one with more than ten times as many parameters. More parameters didn't help. Scaling made the off-screen tracking problem measurably worse. The larger model produced more realistic-looking frames, but it was less accurate about what should have happened to the parts of the scene it wasn't

Cassie Shum discusses the architectural evolution of GraphRAG and why data foundations are critical for advanced AI workflows. She explains how traditional vector RAG falls short when addressing global context, multi-hop reasoning, and provenance. She shares enterprise strategies for building semantically structured knowledge graphs that shift raw orchestrating logic down to the data layer. By Cassie Shum

I've been working as Software Developer mainly focussed on Java and builts many application using Eclipse RCP framework or VS Code Application. Almost all the time I had to deal with multiple large files (either read/generate/validate) them which seemed very difficult and some of them almost impossible as most of them would be dependant on each other and would be referencing each other (just like how java files work together). Now assume client1 requires the same content in multiple Json files and client2 needs it in xml files. We couldn't go on writing a different application or go on adding if conditions and blah blah blah !!!! Wouldn't it be easier if as soon as I execute the application it generates the content in whatever format I choose and also taking care of dependencies/ references (like adding import statements). Additionally integrate with features of IDE and provide proposals, perform validations on the fly. Rela World Examples : Try googling Arxml once (Trust me I've dealing with these files for almost 7 years and it's always a nightmare to debug these) Solution: Xtext framework In this tutorial, I will show you how to use Eclipse Xtext and Xtend to build a simple, readable DSL that automatically generates Java boilerplate for you. Fair Warning: There will be no running executions screenshots or anything. You are gonna have to run it yourself and check the results and of course questions are always welcome in the comments section. But if for some reason you are unable to replicate this then let me know I'll try to explain further. I believe the best way to learn is by doing it yourself. The Goal: What are we building? Instead of writing 100 lines of Java with private fields, getters, and setters, we want our developers to write 5 lines of code in our own custom language (basically you can create your own programming language with your own custom syntax), like this: entity User { var name : String var age : Integer } When this file (assume file extension

At WWDC 26, Apple announced the Core AI framework, the official successor to Core ML. It is designed to allow developers to run large language models and generative AI entirely on-device, supporting both custom-converted PyTorch models and pre-optimized open-source models. By Sergio De Simone

Running a 70B parameter model to summarize a 200-word email is wasteful. Running a 3B model to review production code is reckless. Most systems live somewhere in between — and that's where model routing comes in. It matches task complexity to model capability. The tradeoffs are real, but the savings are too. The routing problem People usually start with one model and stick with it. That works until you notice the cost, or the latency, or both. The alternative is building a router — something that decides which model handles which request. Four strategies work in practice: Capability-based — route by what the model can do Cost-aware — route by what you're willing to spend Latency-aware — route by how fast you need it Hybrid — combine them Each optimizes something different. Picking one is usually a decision about what hurts most. Capability-based routing The simplest approach. Classify the task, send it to the model that handles it. Task Model size Examples Classification, tagging 1-3B Qwen2.5-1.5B, Gemma-2-2B Summarization, extraction 3-7B Qwen2.5-7B, Llama-3.1-8B Code generation 7-14B Qwen2.5-Coder-7B, DeepSeek-Coder-V2 Complex reasoning 14-32B Qwen2.5-32B, Llama-3.1-70B Creative writing, analysis 32B+ Qwen2.5-72B, Claude, GPT-4 If the task doesn't need the bigger model, don't use it. A 1.5B model handles sentiment classification fine. It just won't write a coherent essay. Implementation is straightforward: ROUTING_RULES = { " classify " : { " model " : " qwen2.5-1.5b " , " max_tokens " : 100 }, " summarize " : { " model " : " qwen2.5-7b " , " max_tokens " : 500 }, " code_review " : { " model " : " qwen2.5-coder-7b " , " max_tokens " : 2000 }, " reason " : { " model " : " qwen2.5-32b " , " max_tokens " : 4000 }, " creative " : { " model " : " claude-sonnet-4 " , " max_tokens " : 8000 }, } def route_request ( task_type : str ) -> dict : return ROUTING_RULES . get ( task_type , ROUTING_RULES [ " reason " ]) The catch is classification itself. If you get the task type
