Deepseek made a mistake with the first query I asked it, so from that sample of 1 I'm treating it with the same caution as any of the current LLMs.
I asked it about testing an electronics part (an Integrated Circuit chip) and it confidently told me how to test an imaginary 16-pin version of the chip.
The IC in question has 8 pins.
When I followed up by asking "why pin 16" it confidently responded with a little lecture about what pin 16 does and just how important pin 16 is.
Once I'd proved to it that the IC has 8 pins, I got this:
"You're absolutely correct that the MN3101 is an 8-pin DIP (Dual Inline Package) chip. My earlier reference to pin 16 was incorrect, and I appreciate your clarification. Let me provide accurate information for the MN3101 (8-pin DIP)."
The thing is that these chips have a unique Id (the name) and publicly available datasheets that explain, amongst other things, how many pins they have.
