.blend URL Viewer

Simon Willison released a browser-based .blend URL Viewer that renders Blender 3D model files, demonstrated with a Pluribus-themed Fabergé egg generated by OpenAI's GPT-6 Astra coding agent in Codex. Willison first produced the egg image using ChatGPT Images 2.5, then pasted it into Codex running GPT-6 Astra (high) with a Blender local skill, which took 17 minutes 51 seconds to build several .blend files now published in his vibe-coded-blender-projects GitHub repository.

Tool: .blend URL Viewer https://tools.simonwillison.net/blender-viewer I'm continuing to have a lot of fun with GPT-6 Astra and Blender see my TIL https://til.simonwillison.net/llms/blender-coding-agents-macos . As a big fan of the Imperial Fabergé Easter eggs https://en.wikipedia.org/wiki/Faberg%C3%A9 egg I've always thought it would be fun to make some new ones that celebrate popular culture. Yesterday I decided to try out the new ChatGPT Images 2.5 https://simonwillison.net/2026/Sep/8/introducing-chatgpt-images-25/ by running this prompt https://chatgpt.com/share/6aa1f6d2-a7d8-83ea-92ec-0daeb8422617 : Generate a photo of a faberge egg that's themed after the TV show Pluribus - research first It gave me this - honestly not bad for a first attempt Then, just to see what would happen, I pasted that image into Codex running GPT-6 Astra high and prompted: Use your blender local skill to create a blender model of this faverge egg Here's the skill file https://github.com/simonw/gpt-6-astra-blender-pelican-bicycle/blob/main/outputs/blender-local/SKILL.md , which I created like this https://til.simonwillison.net/llms/blender-coding-agents-macos creating-a-skill . It churned away for 17m51s and built me several .blend files https://github.com/simonw/vibe-coded-blender-projects/tree/main/pluribus-faberge-egg/deliverables . I already had this vibe-coded Blender viewing experiment lying around, so I added that to my tools collection https://tools.simonwillison.net/ and now you can use it to see my Pluribus blender model in your browser https://tools.simonwillison.net/blender-viewer?url=https%3A%2F%2Fgithub.com%2Fsimonw%2Fvibe-coded-blender-projects%2Fblob%2Fmain%2Fpluribus-faberge-egg%2Fdeliverables%2FPluribus Jeweled Egg v1.blend : Tags: 3d https://simonwillison.net/tags/3d , javascript https://simonwillison.net/tags/javascript , tools https://simonwillison.net/tags/tools , ai https://simonwillison.net/tags/ai , generative-ai https://simonwillison.net/tags/generative-ai , llms https://simonwillison.net/tags/llms , blender https://simonwillison.net/tags/blender , coding-agents https://simonwillison.net/tags/coding-agents , codex https://simonwillison.net/tags/codex , gpt-6-astra https://simonwillison.net/tags/gpt-6-astra
