Claude AI is a next-generation large language model family released by Anthropic, a company founded in 2021 by former OpenAI researchers, including Dario and Daniela Amodei . First introduced in March 2023, Claude has evolved through key versions: Claude 2, the Claude 3 series (Haiku, Sonnet, Opus), and most recently Claude 4 (Opus & Sonnet) launched May 22, 2025.
Rooted in Anthropic’s Constitutional AI philosophy, Claude focuses on ethical alignment by following guiding principles rather than relying solely on human feedback—designed to produce helpful, harmless, and consistent responses. It supports high-context understanding (up to ~100K tokens or even 1 million in enterprise), multimodal capabilities (text, images, audio), and excels in reasoning, coding, summarization, and interactive content creation.
The Claude 3 family comprised:
- Haiku – ultrafast and concise,
- Sonnet – balanced performance,
- Opus – premium-grade reasoning and code.
Enterprise use and advanced users now access Claude 4 Opus & Sonnet, further improving logic, hybrid reasoning, and multimodal processing.
Claude is widely praised for its thoughtful, human-like conversational style, strong memory, and ability to process long documents—and stands out as a top choice for coding, research, and educational content creation. Recent additions like the Artifacts feature let users build no-code AI apps and tools directly through chat—functional across free, Pro, and Max tiers.
Accessible at claude.ai, Claude supports web, Windows/macOS desktop, mobile devices, Slack, and API integration. A free tier offers basic access, while paid plans (Pro, Max, Enterprise) provide extended usage, priority models, and enterprise-grade security.
In summary, Claude AI is a secure, multimodal AI assistant built for depth, reasoning, and ethical alignment—ideal for professionals, developers, and researchers who need intelligent, long-form understanding and creative coding support.
