A Taxonomy for Next-gen Reasoning — Nathan Lambert, Allen Institute (AI2) & Interconnects.ai
Overview
This talk explores the evolution of AI reasoning capabilities, moving beyond benchmark scores to focus on practical applications and future development. It posits that while current models excel at specific skills like math and code, the next frontier lies in planning, strategy, and abstraction. Achieving this requires a shift in how models are trained, emphasizing human effort in developing new algorithmic methods and data acquisition strategies.
Who should watch
- AI engineers and researchers interested in the future of language model capabilities.
- Product Managers and builders looking to leverage advanced AI for new applications.
- Developers seeking to understand the practical implications of reasoning and planning in AI.
- Anyone curious about the increasing importance of post-training techniques in AI development.
Key takeaways
- Reasoning models have unlocked new language model applications, enabling tasks like finding specific information or assisting in website development.
- The progression of AI models shows significant gains in task completion time, driven by advancements in reasoning techniques.
- Future AI progress requires deliberate human effort in training models for planning, strategy, and abstraction, not just skill acquisition.
- Calibration is crucial for managing model output and preventing overspending of tokens on simpler tasks.
- Planning involves developing strategies for direction, backtracking, and breaking down complex problems into manageable subtasks.
- Implementation details for planning include memory management, offloading complex thinking, and enabling models to call other models.
- The distinction between pre-training and post-training compute is blurring, with post-training becoming increasingly significant for advanced capabilities.
- Developing robust planning capabilities will require similar human effort and data collection as seen in the development of reasoning skills.
Notable quotes
*A lot of new interesting things are coming down the pipe.*
*Gains aren't free. And I'm thinking that a lot of planning and kind of thinking about training in a bit of a different way beyond just reasoning skills is going to be what helps push this.*
*We really need to think about like how we will actually put this into the models.*
