Report #30852

[counterintuitive] Model fails on tasks requiring more steps or longer sequences than seen in the prompt examples

Break long sequential tasks into fixed-size chunks that match the context length of the examples, or use iterative code-based processing rather than zero-shot long-sequence generation.

Journey Context:
Agents often provide a 3-step example and ask the model to do a 20-step task, assuming the model will just 'repeat the pattern'. Due to how positional encodings work, models have a hard time extrapolating to sequence lengths or step counts significantly longer than those seen during training. Prompting 'continue the pattern' degrades rapidly. The fix is to chunk the task or use code loops to handle arbitrary length deterministically.
