Claude

Claude is a large language model (LLM) developed by Anthropic that excels in conversational assistance, coding, document handling, web-based research, and tool-enabled workflows. It supports text generation, instruction following, code creation, and task delegation via integrated tools. The model leverages agentic capabilities to access external tools, execute code, search the web, and manage extended context across sessions. 

At its core, Claude solves business problems like automating complex knowledge work, accelerating coding workflows, enabling structured tool use (e.g., file editing, shell commands), and delivering fresh, internal or external data through web search. Its architecture supports smooth task chaining and tool use loops that coordinate between user input, Claude’s reasoning, and action execution. 

• Agentic Tool Use: Handles structured operations through a tool-use contract—Claude emits tool calls (e.g., shell commands, file edits, web search) which are executed by the client or Anthropic infrastructure, enabling multi-step workflows （structured integration, side-effect tasks） (<a href="https://platform.claude.com/docs/en/agents-and-tools/tool-use/how-tool-use-works?utmsource=openai" target="blank" rel="noopener noreferrer">platform.claude.com).
• Cross-Platform Access & Memory: Available on web, desktop (Mac/Windows), and mobile (iOS/Android), with memory and personalization features including chat search, preferences, styles, and incognito mode for tailored experiences （continuity and user-centric workflow） (<a href="https://support.claude.com/en/articles/8114491-get-started-with-claude?utmsource=openai" target="blank" rel="noopener noreferrer">support.claude.com).
• Research Tool (Beta for Pro+ Plans): Performs multi-source, agentic web and internal document search, produces systematic answers with citations—ideal for informed decision-making and deep analysis （task accuracy and trust） (<a href="https://support.anthropic.com/en/articles/11088861-using-research-on-claude-ai?utmsource=openai" target="blank" rel="noopener noreferrer">support.anthropic.com).
• Connectors & Visual Components: Integrates external data and renders UI components like forms, charts, and maps via MCP Apps within conversations—enhancing interactivity beyond text （rich interface, data interaction） (<a href="https://claude.com/docs/connectors/overview?utmsource=openai" target="blank" rel="noopener noreferrer">claude.com).
• Model Spectrum & Agentic Coding: Offers multiple Claude models—Sonnet 5, Opus 4.8, Haiku—optimized for agentic coding, reasoning, and cost-efficiency. Sonnet 5 is highlighted as the most agentic, surpassing Sonnet 4.6 in coding benchmarks （e.g., Terminal-bench 2.1） (<a href="https://www.techradar.com/ai-platforms-assistants/claude/claude-sonnet-5-is-here-and-the-most-agentic-sonnet-model-yet-shows-that-the-ai-war-is-shifting-from-chat-to-agents?utmsource=openai" target="blank" rel="noopener noreferrer">techradar.com).

Software Engineers and DevOps: Invoke Claude Code or Sonnet models to automate scripts, run shell commands, edit code, and debug via agent-enabled workflows.

Knowledge Workers and Analysts: Use Research with citation-backed answers and connectors to internal systems for reliable insights and reporting.

Creative Professionals and Content Teams: Leverage long-context models and memory personalization for content generation, style consistency, and project organization across platforms.

• Sign-up & Access: Users can access via web (claude.ai), desktop, or mobile. Eligibility applies (18+; location-supported) (<a href="https://support.claude.com/en/articles/8114491-get-started-with-claude?utmsource=openai" target="blank" rel="noopener noreferrer">support.claude.com).
• Plan Selection: Choose Free, Pro, Max, Team, or Enterprise depending on usage and tools needed (<a href="https://claude.com/pricing?utmsource=openai" target="blank" rel="noopener noreferrer">claude.com).
• Input & Prompting: Enter text naturally. For specialized tasks, specify “use Research” or trigger tool-enabled actions via explicit prompts.
• Agentic Execution Loop: Claude emits structured tool calls (e.g., webfetch, code run). Depending on the tool, execution may be handled by the client (Anthropic-schema or custom) or Anthropic’s server-side tools (<a href="https://platform.claude.com/docs/en/agents-and-tools/tool-use/how-tool-use-works?utmsource=openai" target="_blank" rel="noopener noreferrer">platform.claude.com).
• Result Handling: Claude integrates tool outputs into the conversation, continuing reasoning or delivering final output.
• Session Memory & Organization: Claude leverages memory, chat search, project organization, and styles to maintain context across sessions (<a href="https://support.anthropic.com/en/articles/10185728-understanding-claude-s-personalization-features?utmsource=openai" target="blank" rel="noopener noreferrer">support.anthropic.com).

Claude pricing follows a tiered model:

• Free tier: Web, mobile, desktop access with basic chat, web search, memory, code execution and tools – limited usage capacity.
• Pro: Monthly or annual subscription (discounted annually), includes higher usage, access to Claude Code, Design, Science, Cowork, desktop extensions, projects, memory, web search, Research tool.
• Max (5× / 20× options): Select higher usage packages per 5‑hour session to support heavy workloads, with higher output limits and early access to features.
• Team / Enterprise: Seat-based pricing with usage included, plus admin controls, SSO, compliance, connectors; Enterprise adds audit logs, HIPAA readiness, spend controls, and compliance APIs.
• API usage: Billed separately on créditos/token basis per model (e.g., Sonnet, Opus, Haiku), with input/output token rates and cache pricing. Pay‑as‑you‑go model for programming workflows.

Free trials are inherent to the Free tier. Annual plans offer discounts. Enterprise licensing requires consultation.
