The training systems driving today’s most advanced AIs are distributed, dynamic, and complex. Pre-training relies on layered parallelism and careful fault isolation. Post-training RL spans thousands of GPUs while coordinating verifiers, compilers, and code execution.

Systems complexity pulls focus away from the core algorithms: developers are forced to assemble systems from schedulers, RPC stacks, container orchestrators, observability tooling, service discovery, and app frameworks just to begin work.

Monarch is a distributed programming framework for PyTorch that makes the cluster programmable through a single-program Python API. It exposes the supercomputer as a coherent, directly controllable system—bringing the experience of local development to large-scale training; handling fault tolerance, orchestration, tooling integration, etc.

In this talk, we will demonstrate how Monarch enables developers to focus on training logic rather than glue, extend systems easily, and supervise and debug distributed systems through a unified programming interface.

Attendees will leave with a clear model for building robust, scalable and customizable distributed PyTorch systems using Monarch.
