Fireworks AI

K3 is here. The world's first open frontier model in the 3-trillion-parameter class. Come see how to run it, train it, and put it to work, on Fireworks. We'll give you the tour: what K3 is, where it lands against other frontier models, and why an open model at this scale changes the calculus for what you build and where you run it. How to use K3 on Fireworks inference K3 went live on Fireworks Day 0 for both inference and training. It’s US-hosted, with zero-data-retention options, and you have no GPUs to manage. We'll walk through serverless pay-by-token access and the deployment paths available as your workload grows, so you can go from "curious" to "in production" ASAP. Post-Training K3 on the Fireworks Training API Watch as we post-train an agent on top of K3 using Fireworks’ new serverless training API.
