Cool project, thanks for sharing!

The simulator lets the LLM request renders from different angles/times, so the LLM can get visual feedback. For failures, the simulator also returns status codes like `object_fell` or `mount_initially_collided_with_object` depending on what happened. You can see what the tool call looks like by looking at the Transcript tab, e.g. here https://kerrickstaley.com/ai-cad-design-mount-viz/gso__mug__...

I agree it's not clear how much benefit models get from iteration. Many of the successful runs are one-shots. You can see some examples of basic spatial reasoning e.g. here https://kerrickstaley.com/ai-cad-design-mount-viz/gso__mug__... :

> The initial collision is because the mount was positioned at the same height as the mug's body center (z=-22), causing overlap. I need to lower the mount significantly so the mug starts above it and drops into the cradle.

Ah yes, that matches my observations. It kinda sees that the stuff it is looking for is there, but does not see enough detail to actually notice that not only there is an endcap in the way, but the mug is also rotated the wrong way to sit in the holder.

It feels like the "r's in strawberry" effect where the models do not have enough introspection into the raw input data.

Pretty interesting that simulator-only binary feedback (unless I am reading it wrong) was enough here to build some pretty robust models!

I maintain [1], which provides the models with the ability to render a screenshot from any angle and as far as I can tell, visually driven feedback does not work that well as this point. The models probably don't get enough of "lovecraftian garbled 3D model mess" in the training data or something...

Is the full-sun photo edited to remove the paramotor? I just realized it was in the video shot - the head-down dive “tracking” position of the skydiver in the video happens only a few frames after jumping, only for a few frames, and after that he’s tumbling a bit against the sun, with the paramotor still visible. I’m guessing even if the video and still were two different cameras, they wouldn’t have been far enough apart to catch the skydiver without the paramotor?

Apparently it took multiple tries to get this right. It is possible that the video is from one of the earlier failed attempts.

How close are you?

Oh right, Anthropic doesn't tell you.

I got that 'close to weekly limits' message for an entire week without ever reaching it, came to the conclusion that it is just a printer industry 'low ink!' tactic, and cancelled my subscription.

You don't take money from a customer for a service, and then bar the customer form using that service for multiple days.

Either charge more, stop subsidizing free accounts, or decrease the daily limit.

These days, running `/usage` in Claude Code shows you how close you are to the session and weekly limits. Also available in the web interface settings under "Usage".

How's the Julia ecosystem these days? I used it for a couple of years in the early days (2013-2016ish) and things initially felt like they were going somewhere, but since then I haven't seen it make much inroads.

Any thoughts from someone more plugged in to the community today?

I do wonder in particular about the startup time "time-to-plot" issue. I last used Julia about 2021-ish to develop some signal processing code, and restarting the entire application could have easily taken tens of seconds. Both static precompilation and hot reloading were in early development and did not really work well at the time.

Curiously, a local supplier [1] has been offering raw uranium glass rods for the last few years. There are even artists making new pieces from it [2].
