The dialogue explores reasoning, agency in LLMs, and their relationship with human cognition, highlighting complexities in AI understanding and performance.

This extensive dialogue delves into the evolving landscape of understanding reasoning and agency in large language models (LLMs) and their parallels to human cognition. The conversation initiates with questioning how LLMs perform tasks akin to reasoning and whether this performance is driven by data scale, parameter increases, or an emerging qualitative understanding from vast datasets. Laura discusses her research on procedural knowledge's influence during pre-training and how it plays a crucial role in reasoning capabilities in LLMs, comparing these models' outputs through influence functions. Further, the discussion unfolds around the definitions of agency in AI, emphasizing the need to differentiate between mere mechanistic responses and complex, goal-directed actions that suggest a form of agency in both LLMs and humans.

AI Reasoning Cognition Agency LLMs

Claims:

Claim: LLMs can perform a form of reasoning that resembles human cognitive processes.

Evidence: The paper indicates that models can produce reasoning steps independently without explicit examples during zero-shot tasks, suggesting they employ generalizable strategies.

Counter evidence: Some argue that LLMs primarily operate through retrieval rather than true reasoning, thus questioning how much genuine reasoning occurs beyond learned correlations.

Claim rating: 8 / 10

Claim: Agency can emerge in LLMs beyond programmed goals.

Evidence: Laura mentions definitions of agency that imply an entity actively changing its policy based on environmental feedback, hinting at a potential for LLMs to exhibit agency-like behavior.

Counter evidence: Critics point out that LLMs do not possess true agency or intent since their operations are ultimately based on statistical patterns and not on conscious decision-making.

Claim rating: 7 / 10

Claim: Increasing the scale of training data leads to improved reasoning performance in LLMs.

Evidence: Laura's inquiry post-paper leads her to believe that accessing more data presents opportunities for LLMs to learn complex tasks and procedural knowledge that transcends simple memorization.

- The paper discusses the role of procedural knowledge in pre-training and its impact on reasoning ability.
Scalability and Performance:
- Improved model performance may come from seeing similar examples (memorization) or from learning qualitatively different knowledge.
- The criteria for evaluating models should evolve, as traditional methods (like separating train from test) are less effective with current data practices.
Use of Influence Functions:
- Influence functions help assess how training data affects model behavior, specifically how it informs reasoning steps versus factual retrieval.
Tasks Defined:
- Factual retrieval: Direct queries for concrete answers (e.g., "What is the tallest mountain?").
- Reasoning: More complex tasks requiring synthesis of information, like multi-step arithmetic or solving equations.
Procedural Knowledge:
- Models apply generalizable strategies and can synthesize knowledge from various documents, demonstrating a form of reasoning.
Causality and World Models:
- Effective reasoning is often tied to a robust understanding of causality and the ability to plan for the future based on a world model.
- Agency may emerge from the model's interactions with its environment.
Concept of Agency:
- Agency is defined as the ability to change actions based on environmental feedback and occurs across various levels, from individual agents to collectives (like companies).
- The discussion touches on whether AI systems can possess agency and how it manifests.
AI Safety Concerns:
- Important to ensure equitable distribution of AI capabilities to avoid exacerbating existing societal inequalities.
- As AI becomes more integrated into societal structures, careful management of its influence will be crucial.
