What is Claude AI
Claude AI, also known as Claude.ai, is an AI-driven chatbot specifically designed for generating text. Developed by Anthropic AI, a startup founded in 2021 by former OpenAI team members, the creators behind ChatGPT, Claude AI has made significant strides in the artificial intelligence landscape. In late March 2024, the Claude 3 Anthropic language model surpassed GPT-4 on the Chatbot Arena platform, where users evaluate and compare different AI chatbots to determine a "winner."
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. Its versatile functionalities make it a powerful tool for a wide range of applications, from creative writing to technical problem-solving and even robotic process automation. 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 organizes its models into tiers: Opus (highest capability), Sonnet (balanced performance), and Haiku (fastest, most cost-efficient), with the research-grade Fable line sitting above Opus for long-running agents. The current lineup, verified against Anthropic's model docs, is:
Haiku 4.5. The speed-first model, best suited for high-volume chat, lightweight summarization, basic Q&A, and real-time user experiences. API pricing: $1 / $5 per million tokens (input/output). Supports a 200K token context window.
Sonnet 5. The best balance of speed and intelligence, benchmarking near Opus-level on coding tasks with strong instruction-following and tool reliability. Best for everyday business tasks, coding, content generation, and data analysis. API pricing: $2 / $10 per million tokens (introductory). Supports a full 1M token context window.
Opus 5. Anthropic's recommended default for complex agentic coding and enterprise work, purpose-built for multi-step planning and advanced analysis. API pricing: $5 / $25 per million tokens. Supports a full 1M token context window. For the highest available capability on long-running agents, Anthropic points to Fable 5 ($10 / $50 per million tokens, 1M context).
In May 2025, Anthropic has introduced the 4th generation of models: Claude Opus 4 and Claude Sonnet 4.
Claude Opus 4. Has the highest reasoning capability in the Claude 4 family and was designed for complex analytical tasks, advanced problem-solving, and sophisticated reasoning One of its key pros is superior performance on challenging cognitive tasks, best-in-class reasoning abilities. However, using it can also result inhigher cost and slower response times compared to Sonnet 4.
Claude Sonnet 4. Smart, efficient model optimized for everyday use, balances capability with speed. Some of its main advantages is that it provides faster responses, is more cost-effective, and still highly capable for most tasks. However, it may not match Opus 4's performance on the most complex reasoning challenges.
Sonnet 4 is positioned as the practical choice for daily interactions, while Opus 4 is the premium option for tasks requiring maximum reasoning power. The choice between them depends on whether you prioritize peak performance or efficiency for your specific use case.
Claude Sonnet 4 is freely available, but to use Opus 4 you need to upgrade to Pro.
Key differences between Claude Opus, Sonnet, and Haiku
Anthropic positions Sonnet as the model that competes directly with OpenAI's frontier models on everyday work. Each Sonnet generation has outperformed the one before it on speed, cost, and benchmark results, and Sonnet 5 continues that pattern with the best speed-to-intelligence balance in the current lineup.
Increased performance and speed
Claude 4 Sonnet by Anthropic Claude 4 delivers top-tier performance across reasoning, coding, multilingual tasks, long-context handling, and marketing automation.
It has better performance than earlier generations. While the responses tend to be rich and detailed by default, you can easily guide the model toward more concise outputs by adjusting your prompts accordingly.
When upgrading from earlier model generations to Claude 4, users typically experience significant improvements in overall performance quality. The enhanced capabilities make the transition particularly worthwhile for applications requiring sophisticated reasoning or nuanced communication..
Enhanced capabilities
Looking ahead, I must say that it seems to me Anthropic has released the most powerful language model available for free use. For example, Claude Opus has already shown better results in programming tasks compared to GPT-4 or Gemini Pro. And with the release of Claude 4 Opus, the bar for efficiency has been raised even higher.
Anthropic positions Opus 5 as its recommended model for complex agentic coding, with step-change improvements over previous generations. It can be effectively used for building AI agents. GitHub will be using it as the model powering the new coding agent in GitHub Copilot.
Each generation has shown substantial gains in coding benchmarks. The current Sonnet 5 and Opus 5 models can independently write, edit, and execute code, easily translate code, and are ideal for updating legacy systems or efficiently migrating codebases. This makes it an invaluable tool for software engineering and machine learning tasks.
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
In Anthropic's Claude 3.5 Sonnet, the team introduced the enhanced visual capabilities. Sonnet 3.5 has surpassed Claude 3 Opus in tasks that require analyzing and recognizing visual elements, whether it's charts or illustrations. Anthropic's Sonnet AI easily interprets graphs and diagrams, and accurately transcribes text from images, even if the image is damaged. Additionally, Claude 3.5 Sonnet excels in generating interactive charts and can even create presentations based on JSON data.
For the 4th generation of models, it seems that the main focus was on reasoning and coding skills. However, you can still use the model to generate images and infographics.

Additionally, I want key bolded words to have a blue outline appear around them when hovered over..
What is Artifacts in Claude AI
The Artifacts feature in Claude AI by Anthropic arguably stands out the most among the other Sonnet 3.5 updates. It's not so much a feature, as many reviews describe it, but rather a conceptually new approach to interacting with a neural network among AI chatbot platforms.
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 are an innovative feature that allows users to 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!
Here is an example of how it looks to work with Artifacts in Claude interface.
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.
With Claude 4 Sonnet and the Artifacts feature, Anthropic is setting the stage for a significant leap forward in AI capabilities, offering users enhanced functionality without the barrier of subscription fees. This strategic move not only showcases Anthropic's commitment to innovation but also reinforces Claude's position as a formidable competitor in the AI chatbot landscape.

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. As mentioned earlier, Claude AI excels at creating charts and presentation slides. 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.
You set it up with four pieces. A model makes the decisions (pick Claude as a connected provider, or use another supported model). 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, so the cost tracks how often the automation fires rather than seat count. You can build the flow on the free plan and connect the tools you already use.
Still deciding whether Claude fits your stack? These are the questions people most often ask before they commit.
