About Anthropic

Anthropic develops Claude, a family of large language models. As of October 2026 the current lineup is Claude Fable 5.1, Claude Opus 5.5, Claude Sonnet 5.5 and Claude Haiku 5.5; all accept text and image input, return text output and support tool use, with a 1M-token context window. The models are available through the Claude API, Amazon Bedrock, Google Cloud (Google managed, and since 2026-10-22 also Anthropic managed), Microsoft Foundry and Claude Platform on AWS, and in the Claude apps (Free, Pro, Max, Team and Enterprise plans, with model access varying by plan). Claude Mythos 5.1 shares Fable 5.1's specifications and pricing but is limited to organizations verified through Anthropic's verification programs.
