01 — Overview

What is Kimi?

Moonshot AI became a unicorn almost overnight because of one obsessive technical focus: true, uncompressed long-context memory. Kimi is capable of processing up to 2 million characters in a single prompt without suffering from the common "needle in a haystack" loss that plagues older conversational engines.

Lawyers, researchers, and financial analysts routinely feed Kimi entire company filing archives, hundreds of pages of legal contracts, or full book manuscripts, asking for fine-grained factual cross-checks that it answers with precise line citations.

9.4 EDITOR SCORE

Vinggle verdict The absolute king of long-document digestion. If you need to search and analyze 500-page reports without breaking them into pieces, Kimi is irreplaceable.
