How it works

engine: "m2m100" uses Meta's dedicated 1.2B translation model — cheap and fast, best for plain prose.

engine: "llm" routes through an instruction model, which handles idiom, tone and technical vocabulary far better and is the only option that reliably keeps code blocks untouched.

auto (the default) picks llm when the text contains Markdown structure and m2m100 otherwise.

With preserveMarkdown on, headings, lists, tables, links and fenced code survive translation — code inside fences is never translated.
