What happened

FAQ

What is GPT-6 Astra?

It is OpenAI's latest large language model, used here through Codex with a local Blender skill to build 3D models from a reference image.

How is this different from traditional 3D generation tools?

Traditional tools require manual modeling or scanning, whereas this agent reads the image and programmatically executes Blender commands to produce editable .blend files.

Should MENA design teams adopt this now?

Yes as a first-pass prototyping tool, but outputs need human review for fine detail before commercial or museum use.

What is the .blend URL Viewer?

An open web tool that renders Blender (.blend) files directly in the browser, making it easier to share models with non-technical teams.
