Notable Quotes
“a lot of vision language models generate coordinates token by token, almost like spelling out a location one number at a time. This can be slow and it can also make the box geometry less reliable. But what locate anything does is it uses something called parallel box decoding which means it predicts the whole bounding box together in just one step.”
— Presenter
“Opus 4.8 is four times less likely to allow flaws in its code without noticing them. And it will also push back on bad or weak plans and stay reliable during agentic workflows.”
— Presenter (referencing Anthropic claims)
“The fact that it doesn't just do one variation of juggling, but five different styles makes it even more impressive.”
— Presenter
“real science is messy. You usually don't know the right direction in advance. Some ideas start strong and then they hit a wall. Other ideas look boring at first, but suddenly become useful.”

Chapters
1. Vision Language Models & Image Enhancement
Nvidia released Locate Anything, a vision language grounding model using parallel box decoding for fast object detection across 103 million language queries. Also covered: Control Light for AI-powered image brightness adjustment preserving details, and PID image upscaler achieving 6x speed improvement over competitors like SEED VR2.
2. 3D Scene Reconstruction & Generation
Multiple breakthroughs in 3D generation: Triclat uses triangle primitives instead of Gaussian splats for faster, simulation-ready 3D reconstruction. Gen Recon converts smartphone videos to editable 3D scenes. Physex Omni creates objects with proper physics, joints, and material properties for simulation. Cube Part decomposes generated objects into individual part meshes.
3. Interactive World Models & Game Generators
Scope generates playable first-person shooter worlds responsive to controller inputs including firing and reloading, trained on 70,000 clips from seven FPS games. Gamma World extends this to multi-agent simulations with up to four players simultaneously affecting a shared environment.
4. Video & Audio Editing
Instruct AV-to-AVV system edits video and audio together from text prompts, enabling speech replacement with synchronized lip-sync and voice changes. Pantheon 360 generates consistent panoramic videos from 360° images and camera paths for digital twin creation.
5. Large Language Models: Opus 4.8 & Competitors
Anthropic's Opus 4.8 claims improvements in honesty and code reliability, ranking #1 on some leaderboards but mixed results on others. Independent benchmarks show it competitive with GPT-4.5 but not uniformly superior. Pricing is slightly lower than OpenAI's flagship model. Stefan releases Step 3.7 Flash, an efficient multimodal model for agentic tasks.
6. AI Agents for Scientific Research
Autoscientist framework organizes AI agents into research teams exploring ideas in parallel, sharing experiment logs and dead-end registries. Agents act as analysts and experimenters, beating other frameworks on bioml bench with 24 biomedical tasks. Self-improving models with bidirectional evolutionary search (BEES) use forward and backward search to discover solutions.
7. Humanoid Robotics & Autonomous Systems
Astro Bot's T1 robot priced at ~$13,000 helps with household tasks via wheeled base. Rye Institute's Athena Zero juggling robot learned five juggling patterns in under 10 minutes, demonstrating adaptive real-time coordination. Both represent significant progress in humanoid capabilities.
8. Mobile & Lightweight Models
Bonsai Image compresses Flux 2 Klein from 8GB to 1GB, generating 512x512 images in 9.4 seconds on iPhone. Mini CPM 5 1B is a 2GB dense model outperforming larger competitors on coding, math, and reasoning tasks across most devices.
9. High-Resolution Image Generation & Relighting
Sega method generates ultra-high-resolution images up to 6,144 pixels per side with sharp details, supporting both Flux and Quen base models. Pixel Relights allows interactive relighting of single photos by dragging a cursor to change light angle and intensity while understanding 3D scene geometry.
10. Coding Benchmarks & AI Evaluation
Deep Sweep benchmark tests coding agents on realistic tasks across 91 open-source repositories in multiple languages, requiring autonomous exploration and multi-file editing. GPT-4.5 leads, followed by Claude models, with open-source models scoring significantly lower.
