At the NeurIPS 2025 conference held in San Diego, Google DeepMind emerged as the clear leader among AI labs, marking a pivotal moment for the industry as discussions increasingly pivoted toward reinforcement learning. This year’s gathering, which has transitioned from a strictly academic affair into a significant networking event, showcased the growing importance of specialized model training over traditional data scaling approaches.
Throughout the week, attendees noted that Google’s dominance was reflected in the volume of accepted research papers, with multiple sources highlighting its shifting focus toward “continual, long-term memory rather than just bigger transformers.” According to Thomas Wolf, co-founder of Hugging Face, the sentiment among participants was overwhelmingly positive about Google’s direction, reinforcing its position in the evolving landscape of AI research.
The atmosphere at NeurIPS has dramatically changed since its inception in 1987. Once a forum for academia, it has morphed into a high-stakes recruiting ground, featuring exclusive cruise parties and Michelin-starred dinners that underscore the blurring lines between research and industry. As Anastasios Angelopoulos, CEO of LMArena, proclaimed, “RL RL RL RL is taking over the world,” highlighting the enthusiasm surrounding reinforcement learning as a transformative force in AI.
This transition reflects a broader consensus among researchers and industry leaders that the focus has shifted to an “Age of Research,” a term popularized by Ilya Sutskever, co-founder of OpenAI. According to Nathan Lambert from the Allen Institute for AI, this NeurIPS was notably the first since the launch of DeepSeek R1, marking a shift from closed-model dominance to a more open model landscape. The conference laid bare the dynamics of a rapidly changing competitive environment, with companies like Gemini and Anthropic positioned to rise at the expense of OpenAI.
While Google celebrated its achievements, other labs exhibited mixed fortunes. Attendees noted that although OpenAI and Anthropic still maintain strong positions in the market, the competitive landscape is evolving swiftly, with xAI reportedly receiving little attention during key discussions. The divergence in fortunes among AI labs highlights the industry’s volatility as it adapts to new methodologies and technologies.
The transformation of NeurIPS into a spectacle was underscored by its vibrant party circuit. The invite-only Model Ship cruise brought together over 200 leading researchers, investors, and AI influencers, emphasizing the importance of networking in today’s AI ecosystem. Similarly, the Laude Lounge became a hub for industry luminaries like Jeff Dean and Yoshua Bengio, who participated in what attendees described as “one of the most impressive company events.” However, not all participants embraced this carnival atmosphere; Roon, a noted figure in the field, remarked that “you can learn more from Twitter than from literally being there.”
Amidst the celebrations and networking, significant research trends took center stage. The fields of physical AI and robotics garnered considerable attention, with several researchers predicting these areas will dominate discussions in 2026. The theme of continual learning also emerged prominently, with many attendees suggesting it represents a pivotal frontier for AI capabilities. The participation of Chinese labs such as Alibaba/Qwen, Moonshot/Kimi, and DeepSeek reflected the global nature of the AI competition, with these companies frequently mentioned alongside established Silicon Valley players.
For startups, the conference served as both an opportunity and a cautionary tale. Emerging organizations like Reflection AI made notable impressions with substantial booth presences, while many LLM and image generation startups from the 2022-2024 period are reportedly “quietly dying” due to a lack of differentiation. This underscores the increasing challenges for newcomers in a market that demands innovation and distinctive offerings.
As the dust settles from NeurIPS 2025, the insights and trends emerging from the conference signal a transformative period for AI. With reinforcement learning at the forefront and a shift towards specialized model training, the industry appears poised for a new era of research-driven innovation that could reshape the landscape of artificial intelligence in the years to come.
