Super excited to release DynoSim, the digital twin for @nvidia Dynamo!
Modern inference systems are becoming too large and expensive to experiment with directly. DynoSim brings a digital twin of Dynamo to your laptop.

There's a better way to serve your inference stack, you just haven't found it yet.
DynoSim is a workload-driven simulation of the Dynamo serving stack that turns exhaustive deployment search into a simulate-then-verify loop.
Instead of testing every deployment choice, teams can model the whole stack on one virtual timeline, screen thousands of configurations in high fidelity simulation, then validate only the best candidates on real hardware.
And because it's a full Rust implementation, it runs extremely fast. In our testing, 1,500x faster than real time.

Using an event-driven simulation model and the same architectural concepts as Dynamo, DynoSim enables developers and researchers to evaluate scheduling, routing, KV cache, and system-level optimization algorithms without requiring large GPU deployments.

Now you can prototype new algorithms, explore throughput/latency tradeoffs, and iterate on distributed inference designs before ever touching a production cluster.
Think of it as a digital twin for distributed inference systems.

This is just the beginning. I'm excited to see what the community builds.

Missed to add! DynoSim is written in Rust, it's blazingly fast, and it has native support for @vllm_project, @sgl_project, and more coming soon!
