GPT-5.6 is beating Claude Fable 5 with this collab…
I asked GPT-5.6 Sol in Cursor to set up Blender MCP, create a realistic floating MacBook, and render the final scene.
I'd never opened Blender before that day.
Then I pushed things further.
I built a workflow where Three.js and Blender round-trip assets at real-world scale.
Starting with a Box3D physics system originally built in Three.js with Fable 5, Codex handled the pipeline:
• Verified dimensions in Three.js
• Generated a Blender model at matching scale
• Exported it as a GLB
• Re-imported it into Three.js
• Validated that the visuals still matched the collision system
The results were surprisingly accurate.
The biggest takeaway wasn't the modeling. It was the pipeline.
Controlling Blender through MCP is one thing. Preserving coordinates, origins, orientation, scale, and dimensions across multiple tools is a much harder engineering problem.
I found GPT-5.6 Sol performed best when dealing with architecture, ambiguous requirements, coordinate systems, and final validation.
GPT-5.6 Terra excelled once the work became deterministic, with clear numerical specifications and stable documentation.
The lesson isn't simply that one model is expensive and another is cheap.
It's that the more you separate uncertain reasoning from deterministic execution, the more effectively you can delegate work to smaller, faster models.
AI-assisted development is evolving beyond generating isolated demos. It's becoming capable of coordinating complete production pipelines across Three.js, Blender, physics, assets, validation, and documentation, while the human stays focused on architecture and final judgment.
