## Definition

**Error accumulation** is the compounding of small errors across sequential generation steps: because each step builds on the previous output, an early mistake propagates and grows instead of being corrected. In the channel's material it names a core limitation of LLMs on tasks requiring verifiable correctness or exact determinism.

In the channel's material, **error accumulation** is the failure mode of *step-by-step* generation: each output becomes the input for the next step, so a small mistake early on is copied and amplified, and the result drifts away from what was intended. It is one of the reasons sequential, token-by-token approaches run into trouble when a task demands **exact determinism** or **verifiable correctness** rather than a plausible-looking answer.\{' '\}The discussion of what comes *beyond LLMs* frames error accumulation as a limit that motivates newer architectures: hybrid diffusion–autoregressive video models, which can keep a generated world coherent in real time, and energy-based models, which can check outputs against a verifiable target instead of letting small errors compound unchecked.\{' '\}- **Error accumulation** = small step-level mistakes compounding across sequential generation.- It underlies the LLM limits on *verifiable correctness* and *exact determinism* discussed in the channel.- It motivates alternatives like **diffusion–autoregressive hybrids** and **energy-based models**.
