I haven't had much success yet with this. My ratings follow.

Reading and interpreting datasheets: A- (this has gotten a LOT better in the last year)

Give netlist to LLM and ask it to check for errors: C (hit or miss, but useful because catching ANY errors helps)

Give Image to LLM and ask it to check for errors: C (hit or miss)

Design of circuit from description: D- (hallucinates parts, suggests parts for wrong purpose. suggests obsolete parts. Cannot make diagrams. Not an F because its textual descriptions have gotten better. When describing what nodes connect to each other now its not always wrong. You will have to re-check EVERYTHING though, so its usefulness is doubtful)
