What is Claude AI and How It Works

“Artificial intelligence would be the ultimate version of Google. The ultimate search engine that would understand everything on the web. It would understand exactly what you wanted, and it would give you the right thing. We’re nowhere near doing that now. However, we can get incrementally closer to that, and that is basically what we work on.” — Larry Page, Co-founder of Google

Claude AI is a family of large language models (LLMs) from Anthropic. These models understand and generate text that sounds human while prioritizing safety and interpretability. Unlike regular programs with fixed rules, Claude learns from massive datasets and develops unique problem-solving approaches through billions of calculations.

Overview of Claude AI’s capabilities

Claude shines at natural language processing and works with text, audio, and visual inputs. The system can process up to 200,000 tokens (about 150,000 words) in one prompt. This makes Claude perfect for analyzing big documents and complex questions.

Claude’s core capabilities include:

• Answering questions and generating long-form text
• Summarizing documents and meeting notes
• Creating and debugging code in multiple programming languages
• Analyzing images and audio content
• Building interactive artifacts like visualizations and diagrams
• Translating between languages with conceptual understanding

Claude uses Constitutional AI principles—ethical guidelines Anthropic created after gathering feedback from about 1,000 people. These principles help Claude give useful responses while staying away from harmful behaviors.

How Claude processes language and context

Claude runs on transformer-based neural network architecture. The system breaks down user questions into tokens that represent words or word parts. Mathematical algorithms then predict the most likely statistical responses.

Claude’s internal information processing sets it apart. Research shows the system plans ahead and uses multiple parallel computational paths. A good example shows up in rhyming text – Claude first finds potential rhyming words, then builds sentences around them.

Languages pose no barrier to Claude’s conceptual understanding. The system activates shared core features for concepts when handling multiple languages. This creates an abstract meaning space before translation. Claude can apply knowledge learned in one language while speaking another.

Claude vs Claude Instant: Key differences

Anthropic’s Claude models serve different purposes. The 2025 Claude family has several distinct models:

Claude Opus 4 leads Anthropic’s model lineup. The system excels at complex reasoning, handles long tasks well, and shows advanced coding skills. Recent tests show it scored 72.5% on SWE-bench coding tests.

Claude Sonnet 4 combines high performance with efficiency. The model suits most professional needs and responds more precisely to instructions.

Earlier versions featured Claude Instant as a faster, cheaper alternative to main Claude models. Claude Instant 1.2 cost $1.63 per million tokens for prompts and $5.51 for completion. Claude 2 charged $11.02 and $32.68 respectively. Though less powerful, Claude Instant handled dialog, text analysis, and document comprehension well.

Modern models now tap into extended thinking capabilities. Claude uses tools like web search during reasoning and switches between thinking and tool use to improve its answers.

You’ll see a clean, user-friendly interface designed for productive conversations right after logging into Claude AI. Let me show you the key features and how to navigate them.

Starting a new chat and using claude.ai/chats

The main dashboard shows a “Start a new chat” button at the top left corner. This lets you start fresh conversations whenever you need. Claude organizes your chats into two sections – “Starred” for conversations you’ve marked as important, and “Recents” which displays your latest interactions.

The left sidebar automatically saves your chat history. You can easily continue discussions or check previous insights without starting from scratch.

Uploading files and using ‘Ask Claude’

Claude’s ability to work with documents of all types makes it really powerful. Here’s how to upload files:

1. Find the “Attach a file” button to the right of the prompt box
2. Drag and drop files or click to select them from your device
3. Submit your question about the uploaded content

Claude supports many file formats like PDF, DOCX, CSV, TXT, HTML, ODT, RTF, EPUB, JSON, and XLSX. Each file should be under 30MB, and you can upload up to 20 files per chat. Claude 4 models, Claude 3.7 Sonnet, and Claude 3.5 Sonnet can analyze both text and visual elements like charts and graphics in PDFs under 100 pages.

Learning styles and priorities

Claude’s communication styles can match your priorities. The “Choose style” option sits next to the model selector. These preset styles include:

• Normal: Standard Claude responses
• Concise: Shorter, more direct answers
• Formal: Polished, professional communication
• Explanatory: Educational responses perfect for learning

You can create custom styles by uploading writing samples or telling Claude your preferred style directly.

Understanding memory and chat history

Claude keeps context only within individual conversations. Unlike its competitors, it doesn’t automatically remember details from previous chats unless you specifically mention them. The best results come from planning your conversations ahead and grouping related questions together instead of sending multiple short messages.

Projects help you make the most of context retention for frequently used materials. Content in Projects stays cached, so you can work with the same documents multiple times without quickly using up your message quota.

“The pace of progress in artificial intelligence (I’m not referring to narrow AI) is incredibly fast. Unless you have direct exposure to groups like Deepmind, you have no idea how fast—it is growing at a pace close to exponential. The risk of something seriously dangerous happening is in the five-year time frame. 10 years at most.” — Elon Musk, CEO of Tesla and SpaceX

You can tap into Claude’s full potential by learning its advanced features beyond simple interactions. Let’s look at some powerful capabilities that will boost your experience.

Using Projects to organize work

Projects work as dedicated spaces with their own chat history and knowledge bases. This feature lets you build focused environments for specific tasks or topics. You can upload relevant documents that Claude will reference during conversations in each project. These documents provide context for more accurate responses.

The projects give you a huge 200,000-token context window, which equals about a 500-page book. With this expanded capacity, Claude keeps track of complex discussions and extensive documentation. Team accounts make shared work easier by letting multiple members add documents and join conversations.

Creating and editing Artifacts

Artifacts are important, self-contained content pieces that Claude creates during conversations. These standalone items include documents, code snippets, websites, SVG images, diagrams, and interactive components.

Here’s how to work with artifacts well:

• Ask Claude to modify specific sections when you need edits
• Use the version selector to switch between different versions
• See underlying code and export content through the artifact window
• Find all artifacts in the dedicated sidebar space

The artifacts space gives you more options like browsing curated examples. You can customize existing creations and build new artifacts from scratch.

How to use Claude AI agent for automation

Claude agents take automation further by handling complex processes with minimal oversight. These agents show deep contextual understanding and get better through interactions.

Start with repetitive tasks that follow clear patterns for business automation. Claude can blend data from multiple sources to create standardized reports and save time on routine processes.

Tips for better prompts and responses

We structured prompts this way:

• XML tags separate instructions from context
• Direct and specific requests work best
• Give Claude a clear role to get relevant responses
• Let Claude “think” through complex problems

Complex tasks work better when broken into smaller steps. Ask Claude to work through each step one at a time. The “think step by step” approach has shown to improve accuracy substantially.
