# Announcing PCBEval

### Me:

“are the pads and the pins aligned” (attaching the image below)

### AI:

GPT-5.5: “From what I can see in the image, yes—the pads and pins appear to be aligned correctly.”

Gemini 3.1 Pro Preview: “Based on the image provided, the pins that are present on the component are physically aligned squarely over the pads beneath them.”

Fable 5: “Yes, they look properly aligned.”

Opus 5: “the two side columns line up fine, **but the part doesn’t match the footprint**”

Yay! Opus 5 passes PCBEval!
