Reinforcement learning (RL) is the next frontier, Google is surging, and the party scene has gotten completely out of hand. Those were the through lines from this year’s NeurIPS in San Diego.

NeurIPS, or the “Conference on Neural Information Processing Systems,” started in 1987 as a purely academic affair. It has since ballooned alongside the hype around AI into a massive industry event where labs come to recruit and investors come to find the next wave of AI startups.

I was regretfully unable to attend NeurIPS this year, but I still wanted to know what people were talking about on the ground in San Diego over the past week. So I asked engineers, researchers, and founders for their takeaways. The list below of responses includes Andy Konwinski, cofounder of Databricks and founder of the Laude Institute; Thomas Wolf, cofounder of Hugging Face; OpenAI’s Roon; and attendees from Meta, Waymo, Google DeepMind, Amazon, and a handful of other places.

I asked everyone the same three questions: What’s the buzziest topic from the conference? Which labs feel like they’re surging or struggling? Who had the best party?

The consensus was clear. “RL RL RL RL is taking over the world,” Anastasios Angelopoulos, CEO of LMArena, told me. The industry is coalescing around the idea that tuning models for specific use cases, rather than scaling the data used for pre-training, will drive the next wave of AI progress. What’s clear from the lab momentum question is that Google is having a moment. “Google DeepMind is feeling good,” Hugging Face’s Wolf told me.

The party circuit was naturally relentless. Konwinski’s Laude Lounge emerged as one of the week’s hotspots — Jeff Dean, Yoshua Bengio, Ion Stoica, and about a dozen other top researchers came through. Model Ship, an invite-only cruise with 200 researchers, featured “a commitment to the dance floor that is unprecedented at a conference event,” one of the organizers of the cruise, Nathan Lambert, told me. Roon was dry about the whole scene: “you can learn more from twitter than from literally being there … mostly my on-the-ground feeling was ‘this is too much.’”

Here’s what attendees had to say about NeurIPS this year:

What was the buzziest topic among attendees that you think more people will be talking about in 2026?

Which labs feel like they’re surging in momentum, and which ones feel more shaky?

What was the best party you attended or had FOMO over?

Yes, some people thought keynotes were parties. I guess academia lives on at NeurIPS after all.
