At 4DV.ai, we are working on 4D video creation, playing and editing tools based on Gaussian Splatting. We envision 4D video to be the future of visual media and ultimate medium for immersive storytelling.

DIY pico balloon technology allows affordable global exploration of the stratosphere without satellites thanks to a ham radio network.

Pico-Banana-400K is a large-scale dataset of ~400K text–image–edit triplets designed to advance research in text-guided image editing. Each example contains:

an original image (from Open Images), a human-like edit instruction, and the edited result generated by Nano-Banana and verified by Gemini-2.5-Pro. The dataset spans 35 edit operations across 8 semantic categories, covering diverse transformations—from low-level color adjustments to high-level object, scene, and stylistic edits
