On the other side the latest frontier models are pretty strong in writing embedded C + Assembler code and debugging it afterwards. It's fun to watch it writing crazy complex 'gdb' plugins in Python. This improved brutally.
1. A frontier model (either Opensource or closed source) gets a load of text to review a Kicad project systematically
2. The frontier model can extremely "ask" a cheap Gemini vision model to give it data from datasheets or specs.
Main problem: the quality dramatically hits the shitter done once it falls back to "pdf2latext" due to complex tables.
It was even able to do complex ngspice simulations. But you must offer it all datasheet PDFs.
$1-2 of tokens saved me from $70-80 bugged PCBs.
I stick to cheaper latest generation models on Openrouter (or EU-hosted providers when it comes to IP-protected stuff from work).
Could try screenshotting the PDF and passing that to gemini
