Claude is Anthropic's AI chatbot and language model, known for strong reasoning, a large context window, and safe AI. Free to use; paid from $17/mo. ![The Claude wordmark and sunburst logo on a warm cream background with translucent glass panels](https://fgzcpjbyiakhjifaciaj.supabase.co/storage/v1/object/public/media/what-is-claude-ai.jpg) Claude is an advanced AI chatbot and language model, developed by Anthropic, known for strong reasoning, a large context window, and safe, ethical AI. You can use Claude free via web and app; paid plans start around $17 a month. Pricing and models checked 17 July 2026. This guide covers what Claude is, what it is good at, its current prices and models, and what that means if you want to use Claude in your business. ### What is Claude AI? Claude is the AI built by [Anthropic](https://www.anthropic.com). It is a language model: software that reads, understands, and generates text, in the same category as ChatGPT (OpenAI) and Gemini (Google). Two things make Claude recognisable: a strong emphasis on safe, predictable answers through an approach Anthropic calls Constitutional AI, and the ability to handle very large documents and multi-step tasks (agentic AI). The underlying terms behind all of this live in our [glossary](https://www.whatsnext-ai.com/glossary). One interesting detail explains that focus on safety. Anthropic was founded in 2021 by a group of former OpenAI researchers, among them Dario and Daniela Amodei, who wanted to make AI more predictable and safe. That conviction is built into the design: with Constitutional AI, Claude is given a fixed set of principles for refusing harmful or unreliable answers. For a business, that means a model more likely to say it does not know than to invent a plausible-sounding answer. ### What is Claude good at? In practice you see Claude used most for: - Long documents: Claude can summarise and search long documents, from contracts and reports to policies that run to hundreds of pages. - Reasoning and writing: nuanced text, analysis, and drafts, where many models stay shallow. - Code: writing, analysing, and improving code. The dedicated variant for this is Claude Code. - Agents: Claude supports agentic AI, handling a sequence of steps on its own and checking back only when a decision is needed. For this it uses the Model Context Protocol (MCP), covered below. ### Claude is more than a chatbot Claude is not one product but a set of ways to put the same underlying model to work. For a business, that is the interesting part: you pick the form that fits the job. - Claude Code: Anthropic's coding agent. It works directly in your codebase and can build, debug, and ship code from the terminal, your IDE, Slack, and the web. It is meant to take real development work off your plate, not only to suggest snippets. See [Claude Code](https://claude.com/product/claude-code). - Claude Cowork: an agent that completes whole tasks you can steer from anywhere. Cowork works across your files and tools and hands back finished work for you to review, rather than one answer at a time. See [Claude Cowork](https://claude.com/product/cowork). - Artifacts: a separate window where Claude turns ideas into usable output, from a document or table to a small working tool or app, that you can share straight away. See [Artifacts](https://support.claude.com/en/articles/9487310-what-are-artifacts-and-how-do-i-use-them). - Model Context Protocol (MCP): an open standard for connecting AI to your own data, tools, and workflows, from a database to your calendar. Anthropic likens it to a USB-C port for AI: one way to plug into everything, so an agent can pull context from your own systems. See [modelcontextprotocol.io](https://modelcontextprotocol.io). - Claude Agent SDK: the toolkit for running your own agents on Claude, with the same tools and agent loop that power Claude Code. It was formerly called the Claude Code SDK. This is the layer we build production agents on. See the [Agent SDK documentation](https://code.claude.com/docs/en/agent-sdk/overview). For most businesses, Claude Code and [Cowork](https://www.whatsnext-ai.com/blog/claude-cowork) are the direct entry points; MCP and the Agent SDK are the building blocks for a custom agent. We build on the latter two: production AI agents in code, model-agnostic. ### What does Claude AI cost? Claude costs $0 to over $100 per month for subscriptions (Pro from $17), current as of 17 July 2026; via the API you pay per million tokens. So there are two ways to pay: subscriptions for people using Claude through the app, and API rates for software that calls Claude, such as an agent we build. The subscriptions (amounts in US dollars): - Free: $0. Chat via web and app, with usage limits. - Pro: $17 per month billed annually, or $20 per month. Includes more usage, Claude Code, Claude Cowork, Design, Science, Research, access to multiple models, and Microsoft 365 integration. - Max: from $100 per month, for much higher usage and limits. - Team: $20 to $25 per user per month, with admin controls and single sign-on. - Enterprise: from $20 per user plus usage, with added security and compliance. If you use Claude through the API, you pay per million tokens (a token is about three quarters of a word), with a separate rate for input and output. Roughly, from cheap to expensive: Haiku 4.5 ($1 / $5), Sonnet 5 ($2 / $10 intro), Opus 4.8 ($5 / $25), and the newest tier Fable 5 ($10 / $50). For most business tasks the per-task cost is small; the real question is your monthly volume. Prices in this field move quickly. Always check the current rates on [claude.com/pricing](https://claude.com/pricing) before you decide.

You can use Claude without paying via the web and mobile apps, with limits on how much you can do per period and on access to the heavier models. For occasional use that is often enough. If you hit the limits, or want Claude Code and the better models, Pro is the first step. ### Which Claude models are there? Anthropic offers several models, from fast and cheap to slower and more capable. You pick the model that fits the task, rather than using the most expensive one everywhere. The current line-up (2026-07-17): - Haiku 4.5: the fastest and cheapest, good for simple, high-frequency tasks. - Sonnet 5: the balance of speed and capability, suited to most use cases. - Opus 4.8: the flagship, for the heaviest reasoning and analysis. - Fable 5: the newest tier, with a very large context window as standard. Names and rates change regularly; see [claude.com/pricing](https://claude.com/pricing) for the current list. ### Is Claude better than ChatGPT? The three leading model families (Claude, ChatGPT, and Gemini) are closer together for most business tasks than the marketing suggests. Claude has a reputation for careful writing, long documents, and reasoning. Which one fits best depends more on your task, your data requirements, and your cost profile than on a leaderboard. For a direct business comparison of the two most common choices, see [Claude vs ChatGPT for business](https://www.whatsnext-ai.com/blog/claude-vs-chatgpt). See also our take on whether [Gemini is the best alternative to OpenAI](https://www.whatsnext-ai.com/blog/is-gemini-the-best-alternative-to-openai). ### How do you use Claude in your business? If you want to use Claude seriously in your business, the key lesson is that the model matters less than the system around it. We build production AI agents in code, model-agnostic, so the underlying model (Claude or another) is a swappable part rather than the foundation. Concretely, that means this. When Anthropic ships a new or cheaper model, a model-agnostic setup lets you switch one setting instead of rebuilding your whole solution. You are not tied to one provider's prices and choices. Why that matters is set out in [model-agnostic AI architecture](https://www.whatsnext-ai.com/blog/model-agnostic-ai-architecture). If you want to know specifically what the latest Claude version changes for business, [Claude Opus 4.8: what actually changed](https://www.whatsnext-ai.com/blog/claude-opus-4-8-what-actually-changed-and-why-it-matters-for-your-business) goes deeper. The value sits in the system that gathers the right context, checks the output, and fits your process. At CirFood, a system like that took the number of tenders they evaluated from 4 to 45 per year. The system, not the model, produced that result. The model is the engine, not the car. Want to know whether Claude fits a specific problem in your business?
