Why it matters
Current LLMs degrade on long-horizon narrative coherence. This benchmark provides metrics for evaluating long-form structured content generation and cross-lingual capabilities.
Motivation
Long-form serialized audio drama, with arcs that run for 200 to 800 episodes, is a major creative medium and a setting where frontier large language models (LLMs) fail.
