World Models

A computational framework where an agent learns to predict the future states of its environment by modeling underlying dynamics, enabling planning and reasoning without direct interaction.

Core Principles

• Predictive Dynamics: Modeling the causal structure and physics of an environment.
• Latent Representation: Operating on abstract, high-level features rather than raw, noisy sensory input (e.g., pixels).
• State Estimation: Maintaining an internal belief of the environment’s current state to anticipate future transitions.

Key Architectures & Approaches

• llms: Autoregressive prediction of discrete linguistic tokens; primarily limited by the scope of text-based data.
• vl-jepa: A recent vision-centric approach to AGI emerging from Meta FAIR Lab and Yann LeCun.
  • Core Thesis: “Language is not intelligence”; moves the focus from generative text to visual/sensory world modeling.
  • Departure from Generative AI: Aims to move away from the limitations of chatgpt and purely generative paradigms.
  • Mechanism: Utilizes Joint-Embedding Predictive Architecture to predict information in a latent space, avoiding the computational overhead of pixel-by-pixel generation.
  • Objective: Establishing non-LLM reasoning architectures through visual predictive modeling.
