- R · What Makes It Special
- Anthropic's first publicly available Claude models, launched March 14, 2023 after a closed alpha with partners such as Notion, Quora and DuckDuckGo: a next-generation AI assistant built on Anthropic's research into helpful, honest and harmless AI, offered through a chat interface and the API in two versions, Claude and the lighter, cheaper and faster Claude Instant; a May 2023 update expanded its context window from 9K to 100K tokens. The Claude 1 models were retired November 6, 2024.
