An analysis from the Bone Editorial team at the Chinese WeChat account “骨朵” says live-action short-drama categories expanded from 44 to 65 within 10 months in 2025. In 2026, AI short dramas added themes such as high-concept premises, food and restaurant businesses, stockpiling, science-fiction mecha, and social issues. The analysis argues that AI short dramas use large-scale content experimentation to test whether a theme can work in weeks or days, while long-form productions continue to operate on a multiyear timeline for planning, filming, and release. It examines no-CP female-led stories, system-based farming, high-concept premises, cyberpunk, and infinite-flow as subjects short dramas can test while long-form projects consider whether and how to pursue them.
