What is Claude AI
Claude AI, also known as Claude.ai, is an AI assistant for writing, analysis, coding, and document work. Developed by Anthropic AI, a startup founded in 2021 by former OpenAI team members, the creators behind ChatGPT, Claude now competes directly with ChatGPT and Gemini for both consumer and business users.
Built on Anthropic's Constitutional AI language model, Claude AI is built on the transformer architecture, which has become the benchmark for natural language processing tasks. This architecture efficiently manages sequences of any length, effectively considering the context and relationships between words in various positions.
Claude AI, sometimes referred to as Claud AI, is capable of answering questions, composing texts, generating ideas, solving mathematical problems, and assisting with software engineering tasks. The same chat window handles creative writing, data cleanup, and technical problem-solving, so one tool covers most day-to-day text and code tasks. The safety features of Claude AI make it suitable for various computer use scenarios in both personal and professional settings.
Understanding AI chatbots
If you're already familiar with popular AI chatbots like ChatGPT or Gemini, you'll easily understand how Claude AI works. If you're just beginning your journey with AI assistants and chatbots, don't be intimidated, the platform's operation is incredibly simple and resembles a classic chat window (imagine you're chatting with a colleague on WhatsApp or Slack).
You send the chatbot any message, whether it's composing a poem, solving a math problem, or writing code for your website. The bot responds in real-time within the chat, allowing you to review the answer and continue the conversation by requesting the next task or asking to improve the previous response. This back-and-forth interaction makes Claude AI a practical tool for various computer use scenarios, from casual conversations to complex problem-solving.
A comparison of Claude AI models: Features and differences
Anthropic sorts its models into four tiers: Haiku is the fastest and cheapest, Sonnet balances speed and intelligence, Opus is the recommended starting point for most workloads, and Fable is reserved for demanding reasoning and long-horizon agentic work. Prices below come from Anthropic's API pricing docs as of October 2026.
| Model | Best for | API price (input / output, per 1M tokens) | Context window |
|---|---|---|---|
| Haiku 5.5 | High-volume, latency-sensitive tasks such as classification, extraction, and routing | From $0.10 / $0.50 (prompts over 100K tokens cost more) | 1M tokens |
| Sonnet 5.5 | Everyday work: well-scoped tasks, bug fixes, documents, slides, and spreadsheets | $2 / $10 | 1M tokens |
| Opus 5.5 | Long-running agentic coding and knowledge work; Anthropic's default recommendation | $4 / $20 | 1M tokens |
| Fable 5.1 | Demanding reasoning and long-horizon agents when Opus 5.5 at higher effort falls short | $10 / $50 | 1M tokens |
In the Claude apps, model access depends on the plan. Free users get Sonnet and Haiku, Opus requires Pro or Max, and Fable is available on Pro through usage credits and on Max within its weekly limits. Every current model accepts text and images, supports tool use, and returns text.
Key differences between Claude Opus, Sonnet, and Haiku
The main difference between Opus, Sonnet, and Haiku is how much judgment a task needs versus how much each run costs. In its Sonnet 5.5 announcement, Anthropic describes Opus 5.5 as clearly stronger at complex, open-ended work, and Sonnet 5.5 as strongest at well-scoped everyday tasks, fixing bugs, and building documents, slides, and spreadsheets. Sonnet 5.5 kept the $2/$10 list price of Sonnet 5 and is Anthropic's fastest Sonnet model so far.
Speed and cost for high-volume work
Haiku 5.5, released October 7, 2026, is the model Anthropic recommends for quick, repetitive workloads: summaries, database queries, classification, live customer support, and subagent work alongside Opus 5.5 or Sonnet 5.5. It is the first Haiku model with an adjustable effort setting, so teams can trade cost for intelligence per request. For marketing automation, that makes Haiku the cheaper choice for tagging leads or routing messages, while Sonnet or Opus handles writing and analysis.
Enhanced capabilities
Opus 5.5 is the first model of the Claude 5.5 family. In the Opus 5.5 launch post, Anthropic cut its list price to $4 per million input tokens and $20 per million output tokens, down from $5 and $25 on Opus 5, and raised five-hour usage limits on Pro, Max, Team, and seat-based Enterprise plans. Opus 5.5 is a strong fit for building AI agents that work through long, multi-step tasks.
For software teams, the current Sonnet and Opus models can write, edit, and run code, translate code between languages, and help update legacy systems or migrate codebases. Claude Code, Anthropic's agentic coding tool, works in the terminal, in VS Code and JetBrains IDEs, in the desktop app, and in the browser.
What's more is that both Claude Opus 4 and Sonnet 4 can use the web to extend their thinking and provide better results. They have also introduced Claude Code that supports background tasks via GitHub Actions and native integrations with VS Code and JetBrains and can be a perfect coding assistant.
Additional visual capabilities
Every current Claude model accepts images as input, so it can read charts, diagrams, and screenshots and transcribe text from photos of tables or documents. Claude does not generate images the way an image model does. Instead it builds charts, slides, and interactive visuals as code or files that you can open, edit, and download.
For example, you can upload a screenshot of a monthly traffic table and ask Claude for a presentation slide with a chart of the changes.
Prompt
Please design a visually appealing slide for my presentation that includes a graph illustrating the monthly traffic changes. Use the traffic data from the screenshot of my table.
Artifacts
Anthropic's Artifacts feature lets Claude generate code in a dedicated window next to the chat and show the rendered result right away, such as SVG graphics or a working web page. Artifacts are included on the free plan.
Prompt
Create a visually appealing and creative paragraph design in the form of an "info-box" for my article. Add soft blue shadows, rounded corners, and a subtle animation for the section (e.g., the section with text slightly lifts when hovered over). Additionally, I want key bolded words to have a blue outline appear around them when hovered over..
What is Artifacts in Claude AI
Artifacts in Claude AI are a separate workspace where Claude places the code, documents, designs, and small apps it creates, so you can see and test the result without leaving the conversation.
The essence of this feature is that when a user asks Claude AI to generate content, such as code snippets, text documents, website designs, to draw a picture, or even create a game, the artifacts appear in a special window next to your conversation with Claude AI. For example, if you ask to create a design and HTML code for your landing page, you'll not only see the code but also how your page will look after publishing, displayed in the adjacent window.
What is Artifacts
Artifacts in Claude AI let users generate and view content, such as code, designs, or games, in a dynamic workspace. The generated artifacts appear in a separate window alongside your conversation with Claude AI, enabling real-time editing and visualization of your creations.
This feature enhances productivity by allowing users to immediately copy, download, or publish their work, making it easy to share with colleagues or implement directly.
After reading some incredible examples, I followed a user's recommendation and asked Claude to create a Checkers game. My colleague and I were then able to play it directly in the Claude AI chat window. This creates a dynamic workspace where you can create, view what you've created, and, most astonishingly, edit your creations in real-time within Anthropic's Claude AI. It's simply amazing!
A quick way to test Artifacts is to ask Claude for a small playable game, such as checkers, and play it in the chat window.
Prompt
Create a web-based checkers game and make it playable within Artifacts.
Additionally, after receiving the result, Claude AI will offer you the options to copy the code, download it in the required format, or publish it directly. This is extremely convenient because you can create a landing page or registration form and immediately share the results with colleagues.
Artifacts are part of the free Claude plan, so you can try them right after you log in. Usage limits still apply, and they are lower on Free than on Pro or Max.
Claude AI: API and integrations
For developers, Sonnet 5.5 and the other current Claude models are available through the Claude API, Amazon Bedrock, Google Cloud, and Microsoft Foundry. Typical uses of the Claude API include:
- Text Generation: Easily generate coherent, high-quality responses from user prompts.
- Code Assistance: Includes capabilities like writing, debugging, and translating code for developers.
- Summarization: Quickly extract key points from lengthy texts, perfect for creating summaries.
- Text Classification: Automatically categorize input text into predefined categories based on context.

Because the API is billed per token, companies can add Claude to support, marketing, and finance workflows and pay only for the requests those workflows send. Prompt caching and batch processing lower the cost further for repeated or non-urgent requests.
Claude by Anthropic can also be easily integrated into your workflows or applications through platforms like Albato. By connecting Claude AI with your favorite apps on a no-code platform, you can use the Anthropic AI API to create custom integrations or automated processes without the need for developers or writing any code. This simplifies AI-powered solutions across your business, making it practical for teams to automate tasks and improve efficiency without extra engineering time.
Claude AI vs ChatGPT
Claude and ChatGPT cover the same core jobs, so the choice comes down to workflow. Claude AI from Anthropic is part of the AI chatbot family. This means that the interface, interaction style, and general range of tasks will be similar to what you've experienced before. So, if you've already used ChatGPT, getting started with Claude AI won't be difficult, and you'll quickly figure out how to navigate the platform.
Both Claude AI and ChatGPT offer free tiers. Claude's free plan includes the Sonnet and Haiku models, while ChatGPT's free plan runs on an OpenAI GPT model. Every current Claude model supports up to 1M tokens of context, which matters most when you work with long documents or large codebases.
And yet, which one should you choose, ChatGPT or Claude AI? Choosing between ChatGPT and Claude depends on your specific workflow. Both models are capable, with distinct strengths that cater to different use cases:

How to use Claude by Anthropic for business
The Albato team has experimented with various AI chatbot platforms and, based on their experience, offers a few recommendations on how to effectively use Claude AI for your business:
1. Reduce the need for marketers to rely on developers. Claude AI is the best AI chatbot platform for working with code. Marketing teams often face simple coding tasks that end up being passed to the development team, distracting programmers from more critical tasks and creating a lack of focus. Claude AI can handle: Creating simple designs for forms on your website, generating basic scripts like JavaScript to process data, such as tables with marketing analytics.
2. Handle large datasets with ease. Claude AI can free you from the burden of processing huge amounts of data. For example, if you have user or customer behavior data spanning five years, and you need to create analytical summaries and interpretations, Anthropic's Claude can clean up the tables, remove empty rows, unnecessary symbols, and other clutter. It will find the necessary data, combine it, and calculate the financial and marketing metrics you need.
3. Create charts and presentations. Claude AI builds charts and presentation slides from your data and can export decks as PowerPoint or PDF. Its design capabilities allow you and your team to spend more time working on KPIs rather than crafting visuals for meetings.
4. Text and content generation. Claude AI shines when it comes to text-based tasks. It can save you significant time on content editing and proofreading, help generate article structures for your blog, suggest SEO keywords, and even write or polish your company's social media posts to make them more readable. It can also help brainstorm topics or create a content plan for your marketing strategy.
Run Claude inside an Albato AI Agent
Beyond one-off prompts, you can put Claude to work as the decision-maker inside an automation. Albato's AI Agent is a step you drop into a scenario: it reads the incoming data, decides which action to run, and calls it, instead of you wiring fixed conditions by hand. Claude can be the model behind that step when you connect your own Anthropic account.
You set it up with four pieces. A model makes the decisions: pick Claude AI (Anthropic) as a connected provider and enter the model ID, or choose another supported option such as OpenAI, Gemini, DeepSeek, or Albato's built-in Albato AI. Instructions in plain language describe the task and the guardrails it must respect. Tools are the actions the agent may call, drawn from around 5,000 across connected apps, so it can look something up, write a record, or send a message. Optional memory keeps context across turns for chatbot-style flows.
The field-level control is what makes this safe for real work. For any action you decide which values are fixed and which the agent chooses, using "Let the AI agent decide" per field. Each AI Agent run costs 3 transactions in Albato, and with Claude as the model there is no extra token charge from Albato because Anthropic bills the tokens on your own account. You can build the flow on the free plan and connect the tools you already use.
Outside the AI Agent step, Albato's Claude AI (Anthropic) connector offers a "Run text prompt" action and a long-running variant, so a regular scenario can send data to Claude and pass the answer to a CRM, inbox, or spreadsheet.
