How xAI Scales Image & Video Processing with Ray

Uploaded November 2025 | Updated September 2026, 2 weeks ago

At Ray Summit 2025, Zhibei Ma and Kai-Hsun Chen from xAI share how the company is building a high-performance data processing stack to power some of the world’s most advanced multimodal AI models.

They explain why multimodal data is central to xAI’s mission and how meeting the extreme demands of large-scale training led them to develop a distributed data pipeline built on Ray Core and KubeRay. This system enables efficient processing of massive image and video datasets with linear scalability and robust fault tolerance in production environments.

In this talk, they present the architecture of xAI’s Ray-based data pipeline and the strategies used to achieve high availability and operational simplicity at supercluster scale.

If you’re working on multimodal AI, large-scale data pipelines, or distributed training infrastructure, this session offers deep technical insight from real-world deployment.

$Prompt Learning: A Reinforcement Learning-Inspired Approach to AI Optimization | Ray Summit 2025 At Ray Summit 2025, Jason Lopatecki from Arize AI shares a new paradigm for iterative model improvement—Prompt Learning (PL)—a technique inspired by reinforcement learning but performed entirely through prompts, without weight updates, large datasets, or gradient-based training. He begins by framing the central question: What if we could achieve RL-like gains in model performance simply by refining prompts using natural-language feedback? Building on ideas from NVIDIA’s Voyager and broader community discussions, Arize explores how structured English feedback—evaluations, explanations, annotations—can act as an “error term” that guides models toward better behavior. Jason walks through the conceptual foundation of Prompt Learning and why encoding corrections directly in language can dramatically reduce data requirements—sometimes down to only a handful of examples. Key highlights include: The Prompt Learning framework: How PL adapts RL-style improvement loops to the prompt layer Why natural-language feedback is powerful: Turning textual “error signals” into prompt refinements without extra training PL vs RL efficiency: A head-to-head comparison showing where PL outperforms traditional RL-driven refinement Real-world experiment: Guiding JSON generation with latent constraints using only a few examples TextPRO system: Arize’s PL engine that performs end-to-end optimization through single LLM calls—at a fraction of the supervision cost Jason shares experimental results showing that Prompt Learning can achieve up to 70% test accuracy using just five feedback rules, outperforming standard prompting techniques and demonstrating that lightweight, language-based optimization can yield surprisingly strong results. Attendees will leave with a new lens on iterative LLM improvement—one that opens the door to powerful, low-cost prompt optimization without full RL pipelines or large training sets. Liked this video?
