Recsys Keynote: Improving Recommendation Systems & Search in the Age of LLMs - Eugene Yan, Amazon

Jul 16, 2025 · 20:54

Eugene Yan's keynote presents three innovations for recommendation systems: Semantic IDs, LLM-augmented data, and unified models. Kuaishou’s trainable multimodal Semantic IDs increased cold-start coverage by 3.6% and velocity by 3.5% by clustering content embeddings. Indeed used GPT-4 fine-tuning and distillation to filter bad job recommendations, reducing bad recs by 20% while boosting application rate 4% and cutting unsubscribes 5%. Spotify’s LLM-generated exploratory search queries drove a 9% increase in exploratory queries for new categories like podcasts. Netflix’s Unicorn unified ranker matched or exceeded specialized models across search and recommendations, while Etsy’s unified embeddings with a quality vector achieved a 2.6% sitewide conversion lift and 5% more search purchases.

Veo 3 for Developers — Paige Bailey, Google DeepMind

Jun 21, 2025 · 20:37

Paige Bailey, engineering lead for Google DeepMind's DevRel team, presents Veo 3, the latest video generation model that natively produces synchronized audio—dialogue, sound effects, and music—from text and image prompts, marking a leap in coherence, physics simulation, and cinematic control. She demonstrates Veo 2's creative controls like reference-powered videos, outpainting, and character consistency, and shows how video generation has evolved from 2023's choppy clips to Veo 3's polished raccoon dancing in front of pyramids. A key demo replicates a Chick-fil-A commercial: Veo 2 required stitching multiple tools, while Veo 3 produced the full ad from a single prompt. The models are accessible via Vertex AI private preview and Gemini Ultra plans.
