About This AI

Claude is Anthropic’s family of large language models, with the latest Claude 4.5 series (Opus 4.5, Sonnet 4.5, Haiku 4.5) delivering exceptional intelligence for complex tasks, deep research, coding, analysis, and creative work.

Available via claude.ai (web, iOS/Android apps), it features Artifacts for interactive previews (websites, code, graphics), extended thinking for step-by-step reasoning, Projects for organizing knowledge, web search integration, Google Workspace tools, Claude Code collaboration, and image/text analysis.

Claude 4.5 models excel in benchmarks for coding, math, science, long-context handling, tool use, and safety (constitutional AI principles to minimize harmful outputs).

Free tier provides access to basic models with usage limits; Pro unlocks higher capacity, more models (including Opus 4.5), priority features, and integrations; Max offers massive usage multipliers for power users.

Team and Enterprise plans support collaborative workspaces, custom tools, and secure deployment.

With strong emphasis on reliability, interpretability, and enterprise readiness, Claude powers professional workflows in coding, research, content creation, data analysis, and decision-making.

Launched initially in March 2023 (Claude 1), it has evolved rapidly through Claude 3/3.5 to 4.5 series by late 2025, becoming a top competitor to models like GPT-5 with a focus on helpfulness without unnecessary restrictions.
