Summary
This post details how Runway leveraged Modal's infrastructure for real-time inference of Runway Characters. It highlights the need for sustained low latency, distributing inference across multiple GPUs with high-bandwidth communication, and Modal's capability to enable multi-node GPU clusters with RDMA networking. Runway was able to move from proof of concept to production in under 30 days by adding a single line of code on Modal to achieve this.
