What Is Claude?
Claude is both a family of Anthropic models and a product ecosystem: chat apps, developer APIs, coding agents, workplace connectors, and specialized apps. The simplest way to stay accurate is to separate the model, the product surface, and the billing path.
Claude Central tracks Claude as models, chat apps, coding agents, and APIs because each surface has different pricing, controls, and sources.

Source: Intro to ClaudeThe Short Definition
Claude is Anthropic’s AI assistant and model platform. In everyday speech, people say “Claude” to mean the chat app at claude.ai, but the term also covers the underlying model families — currently Fable 5.1, Opus 5, Sonnet 5, and Haiku 4.5 — that developers call through the Claude API and that Anthropic ships into products like Claude Code, Claude Cowork, Claude in Chrome, @Claude in Slack, Claude Science, Claude Design, and Claude Security.
That distinction matters because a question like “Does Claude have memory?” or “How much does Claude cost?” changes depending on whether you mean the consumer chat app, a Team workspace, Enterprise, Claude Code with a subscription, or API usage through the Console. Claude Central keeps those contexts separate and links each claim to the official page that can change.
The Main Surfaces
The consumer-facing Claude app is where most people encounter Claude first: web, desktop, and mobile chat for writing, analysis, coding help, uploaded files, projects, memory, artifacts, and connectors. The Claude product page positions it as an assistant for people solving complex work, not just a chatbot for short answers.
Claude Code is the developer-agent surface. It can read a codebase, edit files, run commands, integrate with development tools, and work from terminal, IDE, desktop, browser, and other environments. The API is the programmable surface: developers choose models, pass messages, attach tools or documents, and pay by usage.
Claude app
Best for interactive work: writing, analysis, document handling, projects, memory, artifacts, and connectors.
Claude Code
Best for codebase-aware software work, command execution, pull requests, automation, and agentic development.
Claude API
Best for production applications, custom agents, retrieval, batch processing, and model-specific cost control.
Model, Product, And Plan Are Different
The model is the engine. The product surface is where the model is exposed. The plan or billing path decides access, capacity, controls, and cost. For example, Opus 5 is the default model on Claude Max and the strongest model on Claude Pro, and the same model is callable through the Claude Platform — but API usage is billed separately from a Pro or Max subscription.
When evaluating Claude, start by naming the job: occasional chat, daily professional work, heavy personal agent use, team collaboration, regulated enterprise deployment, or developer API integration. Then pick the plan and model with that job in mind.
How To Verify Anything About Claude
Claude details change quickly. The safest verification path is: model names and API IDs in the Models overview; token pricing in Claude pricing and Platform pricing; app features in Help Center articles and the app release notes; enterprise controls in Help Center and the Trust Center; major model launches in Anthropic News.

FAQ
Which Claude model should I start with?
Anthropic’s current guidance is to start with Claude Opus 5 for most workloads, move to Fable 5.1 for demanding reasoning and long-horizon agentic work, use Sonnet 5 for balanced speed and cost, and use Haiku 4.5 when throughput and price dominate.
Is Claude the same as Anthropic?
No. Anthropic is the company. Claude is Anthropic’s AI assistant, model family, and product ecosystem.
Is Claude Code a separate model?
No. Claude Code is a coding-agent product surface that uses Claude models and developer tooling; it is not itself a separate model family.
Where should a new developer start?
Start with the Claude Platform intro, then the Messages API guide, model overview, and pricing page. Claude Central’s API guide links those pages in one path.
