Overview
About this event
Ray Summit is hosted by Anyscale, the company behind Ray. Ray is an open-source framework for scaling AI and Python workloads. The summit gathers engineers, researchers, and open-source contributors, and full details sit on anyscale.com/ray-summit/2026.
The event focuses on AI systems that run under real production load. Talks cover foundation model training, multimodal data, and reinforcement learning. The tone is technical and practitioner-led rather than sales-driven.
The 2026 edition runs across three days in San Francisco. One training day is followed by two conference days. A single pass also covers the co-located vLLM Conference.
What Usually Happens at Ray Summit?
The first day is dedicated to hands-on technical training. The next two days hold keynotes, breakout sessions, and lightning talks. An expo hall and evening party run alongside.
Talks come from teams running Ray in production. Speakers walk through real architecture and lessons learned. Sessions favour working systems over laptop demos.
When Is Ray Summit 2026 Taking Place?
Training day is August 24, 2026. The main conference runs August 25 and 26. The venue is the San Francisco Marriott Marquis, and passes are booked through the Linux Foundation registration page.

Main Topics at Ray Summit 2026
4 topicsThe programme is built around four technical frontiers. These come directly from anyscale.com/ray-summit/2026. The areas below reflect the confirmed focus.
Foundation Model Training
This covers distributed training of large models on Ray. Sessions address performance and scale in production. It targets teams training their own models.
Multimodal Data Curation
This covers building and scaling multimodal data pipelines. It includes processing large, mixed datasets for AI. The focus is production-grade data infrastructure.
Physical AI
This covers AI for robotics and physical systems. An industry roundtable on physical AI runs on day one. Speakers include robotics-focused startups and platforms.
LLM Reinforcement Learning
This covers reinforcement learning for large language models. It includes post-training and high-performance serving. The focus is RL systems running at scale.
Event Experiences
4 topicsThe summit mixes deep technical content with community time. Each format serves a different kind of attendee. The sections below outline what to expect.
Hands-On Training
The first day is full-day technical training. Sessions cover data pipelines, distributed training, and inference. They are led by engineers who build Ray.
Keynotes and Breakouts
Keynotes open both conference days. Breakout sessions run through the afternoons. Lightning talks add shorter, focused technical content.
Industry Roundtables
Two industry roundtables run during the conference. Day one covers physical AI, and day two covers life sciences. These connect practitioners in specific fields.
Expo Hall and Ray After Party
An expo hall runs across the conference days. The Ray After Party follows day one in the evening. Both support networking across the two communities.
Why Ray Summit 2026 Matters
3 topicsRay sits at the core of many production AI stacks. This summit shows how teams run it at scale. Different groups gain different value from attending.
For AI Infrastructure Engineers
Sessions detail real production architecture on Ray. Engineers can learn directly from maintainers. The training day builds hands-on skills.
For ML Platform Leaders
Case studies show how large teams scale AI systems. Speakers come from Apple, Spotify, and Discord. This helps leaders benchmark their own platforms.
For Open-Source Contributors
The co-located vLLM Conference connects two communities. Contributors can meet Ray and vLLM maintainers directly. It is a hub for open-source AI infrastructure.
Agenda
The event runs across three days. Times follow US Pacific Time (PDT, UTC-7). The full session catalogue is on the official site.
