Recent advancements in long-context Large Language Models (LLMs) have
primarily concentrated on processing extended input contexts, resulting in
significant strides in long-context comprehension. However, the equally
critical aspect of generating long-form outputs has received comparatively less
attention. This paper advocates for a paradigm shift in NLP research toward
addressing the challenges of long-output generation. Tasks such as novel
writing, long-term planning, and complex reasoning require models to understand
extensive contexts and produce coherent, contextually rich, and logically
consistent extended text. These demands highlight a critical gap in current LLM
capabilities. We underscore the importance of this under-explored domain and
call for focused efforts to develop foundational LLMs tailored for generating
high-quality, long-form outputs, which hold immense potential for real-world
applications.
