Across the infrastructure layer that powers AI applications, Markdown has been emerging as a new standard. More providers are turning to it as the default output for anything a model needs to read, and moving beyond JavaScript Object Notation (JSON) as the go-to, one-size-fits-all format.

This real, ongoing shift reflects how large language models are trained, how chat interfaces render answers, and how developers actually build with tokens, context windows, and cost in mind. And there is good reason for this adoption.

Markdown fits how models work

Large language models have been trained on enormous amounts of Markdown. Think of documentation sites, README files, technical blogs, forum threads, knowledge bases and so on. That exposure means models already speak Markdown fluently; they know how to analyze its headers, lists, tables, and code fences, and treat them as semantic signals rather than noise.
