## Definition

**Error accumulation** — the compounding-drift problem in autoregressive generation where each predicted frame deviates slightly from the original distribution and becomes the context for the next prediction, so errors compound over time and long video streams degrade into repetition or a single static color. [^08615b13-5661-5b2b-bcb0-3e4b551b9b63@504]

In this channel's material, **error accumulation** describes the compounding-drift problem in autoregressive video generation: a model that predicts the next frame from its own previous output makes a tiny deviation each step. Each deviation becomes the input for the next prediction, so the drift compounds — frame by frame, the generated stream moves further from the original data distribution. Over a long enough stream, output quality collapses into visible artifacts: **repetition** of the same imagery or degeneration into a **single static color**. [^08615b13-5661-5b2b-bcb0-3e4b551b9b63@504]The term appears in the channel's exploration of model architectures beyond standard text-prediction LLMs, where the key question is _how_ a model produces its output. For autoregressive video models, error accumulation is the direct consequence of that design: feeding self-generated frames back as context. Understanding it helps explain why alternative, non-autoregressive approaches are explored for sustained generation tasks. [^08615b13-5661-5b2b-bcb0-3e4b551b9b63@504]- Error accumulation is the compounding drift that occurs when a model conditions on its own previous outputs.- In long autoregressive video streams, it degrades quality into repetition or a single static color.- It is a property of the autoregressive _output process_, which is why the channel raises it when comparing alternative model architectures.
