Researchers introduce PINGPONG, a new benchmark designed to evaluate language models on natural, multi-party, code-switched dialogues across five diverse language combinations. The evaluation reveals existing model limitations in understanding and generating complex code-switched conversations, particularly in generative and semantic tasks.

Key insights

  • Human-authored dialogues in PINGPONG exhibit significantly greater naturalness and structural complexity, including varied message lengths and multi-threaded reply structures, compared to machine-generated conversations.
  • Explicit reasoning mechanisms, whether native to the model or introduced via prompting, consistently improve model performance across the benchmark's tasks.
  • Few-shot learning did not consistently improve performance for Question Answering and Topic Classification, but it yielded notable improvements for Dialogue Summarization across evaluated models.
