I find it pretty good. And Gemini 3.1 pro seems quite capable. Not as good at some things as Claude, but better at others. I was trying to target a verilog design to an uncommon FPGA and board and Gemini went out and searched for the FPGA docs and examined the schematics for the board in able to do the pin assignments (generated .ccf file). Not sure of Claude could've done that.
