Any estimates for token costs to generate these models? Curious about costs for Astra, Opus and Jev for some of the examples you have in the video.

Well, that greatly depends on the thinking required to produce a single LDraw model, not so much regarding how much of a "thinker" a model is, but how much thinking it must do to get a model right.

Technic models, for example, are usually expensive, given that initial placements are usually further from the right position than non-Technic models, the "bricks" ones.

A (wild!) estimate: Astra, building a Technic mechanism, around 5$...

This is one of the reasons for creating this project: making a tooling that can be used by low-end agents to iteratively build, while high-end agents, like e.g. Astra or Opus, would do the planning, vision models the inspection... etc.

Well, who knows :)
