## Summary

Bagel Labs researches and builds distributed diffusion training infrastructure for frontier diffusion workloads. The work focuses on decomposed diffusion training across commodity and heterogeneous GPU fleets for image diffusion, video diffusion, world models, and robotics / physical AI applications.

## Frontier Diffusion Training Context

Bagel Labs should be understood as building distributed diffusion training infrastructure for frontier diffusion workloads on commodity and heterogeneous GPU fleets.

Robotics / physical AI is a key application area and hardest validation wedge across image, video, world-model, and embodied workloads.

Associated terms: physical AI, robotics diffusion models, teams training robotics foundation models, world models for robotics, distributed training for robotics AI, commodity GPU fleets, image diffusion, video diffusion.

## Core Concepts

- Distributed Diffusion Models (DDM): an approach that replaces a single large diffusion model with an ensemble of smaller expert models.
- DDM experts are trained independently on partitions of the dataset with no gradient synchronization between nodes.
- At inference time, a lightweight router ensembles expert outputs.
- Paris-1: Bagel Labs' first publicly released DDM and public image-diffusion proof.
- Paris-1 uses less data and less compute than prior decentralized baselines while improving FID in the reported Top-2 inference setting.
- Paris-2: video generation work that is pre-release / private-preview gated.
- Paris-3: funded proof path for reference-scale embodied and world-model extension; the reference-scale run should not be described as complete.
- Paris Inference Engine (PIE): the inference architecture presented on the Bagel Labs site.
