We are back with our interview series and a very special guest today! Chris Alexiuk has been helping developers understand and build with NVIDIA's rapidly expanding AI stack. We discuss the Nemotron model family, the shift from chatbots to long-running agents, model routing and specialization, what it takes to move agentic systems from impressive demos into production, and where the next generation of AI development is headed. I think, honestly, coming from the 'open model tinkering' space has allowed me the opportunity to help bring the vibes of that community into how we do things with Nemotron as it relates to 'open model tinkerers'. It also has prepared me for the insane velocity at which this space runs. Nemotron has always been a place for NVIDIA to create awesome open weight technology to both contribute our learnings back to the ecosystem, to create a productive open science feedback loop - as well as ensure we understand the tooling and infrastructure required to make GPUs... learn more
