Toward provably private learning from federated data

Katharine Daly, Yu Xiao, Zachary Garrett +9

Federated Learning (FL) allows devices with private data to collaborate in training a shared model. We present a next-generation FL system based on Trusted Execution Environments (…

Decoupled DiLoCo for Resilient Distributed Pre-training

Arthur Douillard, Keith Rush, Yani Donchev +14

Modern large-scale language model pre-training relies heavily on the single program multiple data (SPMD) paradigm, which requires tight coupling across accelerators. Due to this co…

Gemini 2.5: Pushing the Frontier with Advanced Reasoning, Multimodality, Long Context, and Next Generation Agentic Capabilities

Gheorghe Comanici, Eric Bieber, Mike Schaekermann +3431

In this report, we introduce the Gemini 2.X model family: Gemini 2.5 Pro and Gemini 2.5 Flash, as well as our earlier Gemini 2.0 Flash and Flash-Lite models. Gemini 2.5 Pro is our…

Communication-Efficient Language Model Training Scales Reliably and Robustly: Scaling Laws for DiLoCo

Zachary Charles, Gabriel Teston, Lucio Dery +5

As we scale to more massive machine learning models, the frequent synchronization demands inherent in data-parallel approaches create significant slowdowns, posing a critical chall…

Streaming DiLoCo with overlapping communication: Towards a Distributed Free Lunch

Arthur Douillard, Yanislav Donchev, Keith Rush +11

Training of large language models (LLMs) is typically distributed across a large number of accelerators to reduce training time. Since internal states and parameter gradients need…

DrJAX: Scalable and Differentiable MapReduce Primitives in JAX

Keith Rush, Zachary Charles, Zachary Garrett +2

We present DrJAX, a JAX-based library designed to support large-scale distributed and parallel machine learning algorithms that use MapReduce-style operations. DrJAX leverages JAX'…

Leveraging Function Space Aggregation for Federated Learning at Scale

Nikita Dhawan, Nicole Mitchell, Zachary Charles +2

The federated learning paradigm has motivated the development of methods for aggregating multiple client updates into a global server model, without sharing client data. Many feder…

Towards Federated Foundation Models: Scalable Dataset Pipelines for Group-Structured Learning

Zachary Charles, Nicole Mitchell, Krishna Pillutla +2

We introduce Dataset Grouper, a library to create large-scale group-structured (e.g., federated) datasets, enabling federated learning simulation at the scale of foundation models.…

Federated Automatic Differentiation

Keith Rush, Zachary Charles, Zachary Garrett

Federated learning (FL) is a general framework for learning across an axis of group partitioned data (heterogeneous clients) while preserving data privacy, under the orchestration…

A Field Guide to Federated Optimization

Jianyu Wang, Zachary Charles, Zheng Xu +50

Federated learning and analytics are a distributed approach for collaboratively learning models (or statistics) from decentralized data, motivated by and designed for privacy prote…

On Large-Cohort Training for Federated Learning

Zachary Charles, Zachary Garrett, Zhouyuan Huo +2

Federated learning methods typically learn a model by iteratively sampling updates from a population of clients. In this work, we explore how the number of clients sampled at each…

Local Adaptivity in Federated Learning: Convergence and Consistency

Jianyu Wang, Zheng Xu, Zachary Garrett +3

The federated learning (FL) framework trains a machine learning model using decentralized data stored at edge client devices by periodically aggregating locally trained models. Pop…

Federated Reconstruction: Partially Local Federated Learning

Karan Singhal, Hakim Sidahmed, Zachary Garrett +3

Personalization methods in federated learning aim to balance the benefits of federated and local training for data availability, communication cost, and robustness to client hetero…

Adaptive Federated Optimization

Sashank Reddi, Zachary Charles, Manzil Zaheer +5

Federated learning is a distributed machine learning paradigm in which a large number of clients coordinate with a central server to learn a model without sharing their own trainin…

Advances and Open Problems in Federated Learning

Peter Kairouz, H. Brendan McMahan, Brendan Avent +56

Federated learning (FL) is a machine learning setting where many clients (e.g. mobile devices or whole organizations) collaboratively train a model under the orchestration of a cen…
