GPT-6 Astra Generates Fabergé Egg, Codex Builds Blender Model
Simon Willison demonstrates the creative potential of OpenAI’s latest tools by generating a Fabergé‑egg image themed after the TV show Pluribus using ChatGPT Images 2.5. He then feeds the image into Codex running GPT‑6 Astra, which spends 17 minutes and 51 seconds producing several .blend files that model the egg.
Key points
- ChatGPT Images 2.5 produced a Fabergé‑egg image themed after *Pluribus*
- Codex with GPT‑6 Astra converted the image into a Blender model in 17 min 51 s
- The workflow demonstrates multimodal AI orchestration for creative design
The resulting Blender files are added to Willison’s local viewing experiment, allowing anyone to view the 3‑D model directly in a browser. The post showcases how a large language model can orchestrate a chain of tools—image generation, code execution, and 3‑D rendering—to create a complete creative workflow.
This experiment highlights the growing ease with which multimodal AI can be leveraged for design tasks, illustrating the practical integration of image, code, and 3‑D modeling capabilities in a single prompt‑driven pipeline.

I'm continuing to have a lot of fun with GPT-6 Astra and Blender (see my TIL).
As a big fan of the Imperial Fabergé Easter eggs, 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 by running this prompt:
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, which I created like this.)
It churned away for 17m51s and built me several .blend files. I already had this vibe-coded Blender viewing experiment lying around, so I added that to my tools collection and now you can use it to see my Pluribus blender model in your browser:
