Chat with nemotron-3-ultra — free

Nemotron is NVIDIA's open model family, tuned hard for helpful, instruction-following assistant work. nemotron-3-ultra is the top of the line: a strong generalist that gives direct, well-organised answers.

It's a good second opinion, too — ask it the same question you asked another model and compare. On Kafana switching models mid-conversation is one click, and every reply is badged with the model that wrote it.
