Claude

Claude is a family of large language models developed by Anthropic, designed for writing, coding, reasoning, and agentic workflows with advanced safety and alignment principles.

Its core engine enables planning, tool execution, browser and terminal use, and integrated long‑context comprehension—solving business problems like summarizing lengthy documents, autonomous task execution, and deep code understanding.

Recent releases such as Opus 4.8 and Sonnet 5 deliver improved agentic coding, reasoning, and multi‑step planning, making Claude suitable for professionals who need AI to autonomously execute complex workflows.

• Million‑token context window: Models like Sonnet 5 and Opus support up to 1 million tokens, allowing full documents, codebases, or datasets to be processed at once—removing chunking overhead and enabling coherent analysis across large inputs.
• Agentic capabilities: Claude Sonnet 5 and Opus 4.8 perform planning, tool invocation, and autonomous task execution (e.g., browser, terminal), enabling workflows rather than mere Q&A.
• Claude Code: Terminal‑based coding agent integrated in Pro and above, executing commands, editing files, and reviewing code, streamlining software workflows under the safety‑first architecture.
• Constitutional AI safety: Claude’s models are trained with a constitution-based approach to enforce honesty, user autonomy, and safe reasoning—providing more consistent, transparent behavior.
• Projects and Artifacts persistence: Claude offers persistent memory features like Projects and Artifacts that store context, code snippets, and documents across sessions, supporting long-term workflows.

• Software developers: Use Claude Code enhanced by agentic control and long‑context models to automate coding, refactoring, and multi‑file codebase understanding.
• Writers and analysts: Leverage million‑token context for drafting, editing, and analyzing long documents or reports without manual chunking.
• Researchers and scientists: With Claude Science workbench and persistent memory, integrate fragmented research tools and workflows into a unified environment.
• Enterprise users: Use Team and Enterprise plans with context configuration, compliance features (SSO, SCIM, HIPAA readiness), and admin controls to scale AI across organizations safely.

• User registers on Claude.ai and selects a plan: Free, Pro, Max, Team, or Enterprise.
• Access the chat interface or API, where they choose a model—Haiku, Sonnet (now Sonnet 5), or Opus (currently Opus 4.8).
• Input is processed, with context spanning up to 1 million tokens; optional Projects and Artifacts retain state across sessions.
• Agentic tasks (coding, browsing, planning) are executed via Claude Code or integrated tools under the model’s guidance.
• Response is generated with constitutional AI safety checks; user receives output in chat or API.
• Cache mechanisms (prompt caching) optimize repeated prompts for cost-efficiency.

Claude uses a tiered subscription model: a Free tier with limited daily access to Sonnet, a Pro plan (~20 USD/month) with priority access to Sonnet 5 and Opus, and Max tiers (~100–200 USD/month) offering 5× to 20× Pro usage capacity. Team and Enterprise plans offer per‑seat or custom pricing with additional control and compliance features. A separate API path is priced per million tokens (input/output), with model‑dependent rates for Haiku, Sonnet, and Opus.
