Y Combinator Summer 2024 company Outerport is launching a service that enables AI model weights to be swapped in production without server restarts or service interruption, according to its Launch HN post, which drew 93 points on Hacker News. The core capability targets teams running multiple models or pushing frequent weight updates — workflows where traditional deployment cycles require taking servers offline. Outerport's approach allows the underlying model to change while the serving endpoint remains live. No pricing, infrastructure requirements, or supported model formats were disclosed in the available signal. For operators running continuous inference workloads, the practical implication is straightforward: model version rollouts and A/B weight testing no longer require scheduling maintenance windows or absorbing availability hits during transitions.
