What is Claude? The Story of Anthropic and Its Goals

Claude is a large language model (LLM) introduced by Anthropic, an AI startup, in 2022. Anthropic was founded by Dario Amodei, Daniela Amodei, and other ex-OpenAI researchers who parted ways with OpenAI due to differing views on AI development priorities. They established Anthropic to focus on safety and transparency in AI. The name "Claude," inspired by Claude Shannon, the father of information theory, reflects Anthropic’s commitment to scientific principles and innovation.

Anthropic’s primary mission is to develop AI that is not only powerful and efficient but also safe, ethical, and trustworthy. The company employs a concept called Constitutional AI, where AI models are trained based on specific ethical principles to prevent harmful or unethical outputs. This approach sets Claude apart from many competitors, making it an appealing choice for developers and organizations seeking responsible AI tools.
 

Key Features of Claude and Its Versions

Claude has been released in multiple versions, each with distinct features and capabilities. Below, we explore the key versions and their standout features:

1. Claude 1

Launched in March 2023, the first version of Claude offered basic capabilities in natural language processing, answering questions, and performing text-based tasks like summarization and translation. However, compared to later versions, it had limitations in coding and mathematical reasoning.

2. Claude 2

Claude 2 marked a significant leap forward with an expanded context window of 100,000 tokens (roughly 75,000 words) and improvements in reasoning and coding. This version enabled the uploading and analysis of lengthy documents, such as PDFs, and delivered greater accuracy in responses.

3. Claude 3 and 3.5

The Claude 3 family includes Haiku (fast and lightweight), Sonnet (balanced and optimized for speed), and Opus (the most powerful model). Claude 3.5 Sonnet, the latest version as of December 2024, excels in coding, reasoning, and data analysis. These models also support image analysis and JavaScript code execution, making them highly practical for developers.

Key Features

  • Large Context Window: Claude 3.5 Sonnet processes up to 200,000 tokens, enabling analysis of lengthy documents.

  • Safety and Ethics: Constitutional AI minimizes harmful or unethical content.

  • Multilingual Support: Supports various languages, including Persian, though its primary focus is English.

  • Coding Capabilities: Autocompletes code, explains code, and writes code in languages like Python and JavaScript.

  • Data Analysis: Extracts key insights from text files, PDFs, and spreadsheets.

  • External Tool Integrations: Through the Model Context Protocol (MCP), Claude connects to popular tools like Zapier, Stripe, Cloudflare, and PayPal. This allows users to extract data or perform actions, such as creating invoices or managing projects, using simple text commands. Currently available for Max plan subscribers, it will soon extend to Pro plan users.
     

How Claude Works: A Focus on Safety

Claude is built on advanced deep learning architectures and natural language processing (NLP) techniques. Its distinguishing factor is the Constitutional AI approach, where the model is trained with a set of ethical principles acting as a "constitution." These principles include preventing harmful content, respecting privacy, and providing honest, helpful responses.
 

How Does Constitutional AI Work?

  1. Training with Ethical Principles: The model is trained on data filtered based on safety and ethical values.

  2. Human Feedback (RLHF): Claude uses reinforcement learning with human feedback to align responses with user needs.

  3. Transparency in Decision-Making: Anthropic is working to make the model’s decision-making processes more transparent, particularly through projects like "mechanistic interpretability," aiming to "open the black box" of AI by 2027.

This approach makes Claude more cautious and safer than models like ChatGPT, though it can sometimes limit creativity due to its conservative stance.
 

Accessing and Using Claude

Claude is accessible through various platforms, though geographic restrictions may require users in some countries (e.g., Iran) to use a VPN. Steps to access Claude include:

  1. Sign Up with Anthropic: Users can visit anthropic.com and create an account to access Claude.

  2. Mobile and Desktop Apps: Claude is available on iOS and Android via the PML Playground app.

  3. API for Developers: Anthropic offers a robust API for developers to integrate Claude into their applications.

  4. Subscription Plans: The free version of Claude has daily question limits, while paid plans like Claude Pro and Team offer unlimited access and advanced features.
     

Connecting Claude to External Tools (Integrations)

In a recent update (May 2025), Anthropic introduced Integrations, enabling Claude to connect to external tools like Zapier, Stripe, Cloudflare, PayPal, and more via the Model Context Protocol (MCP). This feature allows users to extract data, such as sales information or project statuses, or perform actions like creating invoices in PayPal and managing tasks with simple text commands. For instance, integration with Zapier enables Claude to automate workflows across multiple applications.

Currently, this feature is available for Max plan subscribers, with plans to extend it to Pro plan users soon. Developers can use Anthropic’s documentation to create custom MCP servers, integrating Claude with internal systems. This capability transforms Claude into a powerful tool for automation and complex project management.
 

Advantages and Applications of Claude

Claude’s unique features enable a wide range of applications across various domains. Below are its key advantages and applications:

Advantages
