Claude Opus 4.7

Answer: As of my knowledge, Anthropic's Claude model family includes the Claude 1, Claude 2, Claude 3, and Claude 3.5 generations, with specific variants such as Claude 3 Haiku, Sonnet, and Opus, plus Claude 3.5 Sonnet and Claude 3.5 Haiku.

Here is a breakdown of the Claude models I am aware of, organized by generation: **Claude 1 series (2023):** The original Claude and Claude Instant, released in early 2023. These are largely deprecated now. **Claude 2 series (2023):** Claude 2 and Claude 2.1, which expanded the context window (up to 200K tokens with 2.1) and improved reasoning. Also Claude Instant 1.2 as a faster, cheaper option. **Claude 3 series (March 2024):** Released as a tiered family: - Claude 3 Haiku — smallest, fastest, cheapest - Claude 3 Sonnet — mid-tier balance of speed and intelligence - Claude 3 Opus — largest and most capable in the Claude 3 generation **Claude 3.5 series (2024):** - Claude 3.5 Sonnet — released June 2024, with an upgraded version released in October 2024 (sometimes called "Claude 3.5 Sonnet (new)" or v2) - Claude 3.5 Haiku — announced in late 2024 Anthropic also introduced features alongside these models such as Artifacts and "computer use" capability (with the upgraded 3.5 Sonnet). **Important caveat:** My training data has a cutoff, and Anthropic releases new models regularly. There may be newer models (such as a Claude 3.5 Opus or Claude 4 generation) that I am not aware of. For an authoritative, up-to-date list, the Anthropic website (anthropic.com) and their API documentation are the best sources.
