Mozilla’s CTO explains the difference between open source and open weight models, offers practical advice, and reviews the State of Open Source AI report.

More companies are running open models for everyday AI work to gain control and reduce costs. This episode explores open source and open weight AI with Raffi Krikorian, Mozilla’s Chief Technology Officer, who leads its open source AI strategy and spearheaded Mozilla’s State of Open Source AI report.

What we'll discuss with Raffi:

Open weight models differ from open source models, and the license terms matter
Everyday work now runs well on open models for far less money, while frontier models keep an edge on the hardest tasks,
Procurement, compliance and support decide whether open models reach production in large companies

Open source AI models now trail the best closed models by only a few points at a fraction of the price, yet large companies are slow to put them into production. In June, after a government export order, the newest frontier models went offline for almost three weeks for every company that rented them.

CXOTalk episode 933 examines what open source and open weight models are, where they beat closed models and where they do not, and how an executive decides between renting and owning AI. Our guest is Raffi Krikorian, Chief Technology Officer at Mozilla, which recently published the State of Open Source AI report.

What we will cover:

What open source AI models are, and how open source differs from open weight
Where open models are winning and where frontier models are better, from Mozilla’s State of Open Source AI report
When to rent AI from a closed provider, when to own an open model, and the economics of each
The risks and limits of open models: procurement and compliance, models from Chinese labs, and the line on what should be open
Lock-in beyond the model: the memory, tools and data around it, and how companies keep an exit open
Open source AI as a board-level issue, and the questions boards should ask
