.blend URL Viewer
Simon Willison demos a .blend URL viewer built with GPT-6 Astra in Codex and ChatGPT Images 2.5 generating Blender models.
Simon Willison used ChatGPT Images 2.5 to generate a Faberge egg concept image themed after the TV show Pluribus, then had Codex running GPT-6 Astra (high) execute a Blender local skill to build a 3D model from it. He published the result as a .blend URL viewer tool and continues experimenting with agentic Blender workflows. The post is a hands-on demo of AI-driven creative tooling rather than a security or release announcement.

From the original article
Tool: . blend URL Viewer 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.
