Claude
Claude supports 100K-token context windows (~75,000 words) to ingest hundreds of pages and hours of content.
Anthropic expanded Claude's context window from 9K to 100K tokens (around 75,000 words), enabling businesses to submit hundreds of pages for Claude to digest and analyze and allowing conversations to continue for hours or days. Anthropic demonstrated loading The Great Gatsby (72K tokens) into Claude-Instant and detecting a single modified line in 22 seconds. The announcement notes 100K tokens correspond to roughly six hours of audio (AssemblyAI demo) and that the capability is available via Anthropic's API. Use cases listed include document summarization and explanation, company strategic analysis from annual reports, legislation assessment, legal-document risk/theme identification, surfacing answers from large developer documentation, and prototyping from an entire codebase.
