Claude Sonnet

Claude Sonnet is a family of large language models developed by Anthropic, positioned as a mid-tier offering that balances processing speed and computational cost. The Claude 3 Sonnet version, described in a March 2024 BlueRun Ventures piece, was priced at $3 per million input tokens and $15 per million output tokens with a 200K context window, and was marketed as more economical than peers at similar intelligence levels for large-scale enterprise deployment . Its stated use cases span data retrieval and RAG, sales and marketing automation, code generation, and image-to-text extraction .

The broader Claude product line has since evolved: entity cards in elsewhere's system reference Claude 3.5 Sonnet, Claude 3.7 Sonnet, and Claude Sonnet 4 as subsequent iterations , though elsewhere's corpus does not contain detailed profiles of these later versions. Related coverage notes that Claude Code, an AI-native software development tool, has been discussed as part of Anthropic's expanding product ecosystem , and that Anthropic itself has been profiled as "building the most dangerous technology, and trying to be good" .
