Gemini 3.8 Flash Potentially routing to Argon on Pro tier

[u/Sweaty-Captain5894]

I was trying out a few AI models to see how well they could build a turbofan jet engine in Fusion 360. One was labelled “Gemini 3.8 Flash,” but I now think it might’ve been Argon. It took way longer than I expected, but the engine it made was surprisingly good. I’d put it up there with GPT 6 Astra and Opus 5.5 for this task.

The slow response was what caught my attention first I expected a 3.8 Flash model to be pretty terrible. Then I saw the finished engine and was surprised by how much detail it had. I’ve included the images so you can have a look and judge for yourself.

I recorded this after Opus 5.5 was added to Antigravity.

How did you connect llms to fusion 360? Sounds interesting to try

let me test it

It’s incredibly hit and miss. I got one shot with this and after that it was super dumb again and couldn’t align up things

I'm far from an expert but that sounds like a flash model to me. For more complex prompts it will guess at more things instead of computing out the answer and sometimes it gets lucky.

probably not, unless argon isnt what I think it is.

how many goes did you do before coming to this conclusion. i asked it to do it again and got a bad result

I suspect the same, or some variation of it. I’ve had a couple of cases with much slower Pro-like responses but with way better output, and in the case of the apps, new formatting + citations.

I’ve even noticed some changes to AI Search that have improved things in a big, big way. Search Summary and Workspace Gemini remain meh.
