Chat with deepseek-v4-pro — free

DeepSeek's models earned their reputation on hard problems: mathematics, algorithmic coding, and long chains of reasoning that trip up smaller models. deepseek-v4-pro is the current flagship of that line.

Pick it on Kafana when the question has real depth — debugging a tricky function, working through a proof, or comparing options where the details matter. It's free, straight from the model picker.
