## Summary

Claude 3.5 Sonnet topped coding and reasoning benchmarks in 2024; Claude 3.7 Sonnet with extended thinking launched in February 2025 as the leading model for complex professional tasks.

## Company Overview

Claude is Anthropic's AI assistant, first released publicly in March 2023 and now one of the top three most-used AI assistants globally. Claude 3.5 Sonnet (June 2024) set benchmarks for coding, analysis, and instruction-following that led many developers and enterprises to migrate from GPT-4. Claude is available via claude.ai (free and Pro tiers at $20/month) and through the Anthropic API powering thousands of enterprise applications.

Anthropic's competitive advantage is its Constitutional AI safety methodology and its reputation as the most 'thoughtful' and reliable AI for professional work — legal analysis, coding, writing, and research. Claude 3.7 Sonnet, launched February 2025, introduced extended thinking (up to 128K tokens of reasoning) for complex multi-step problems. Anthropic reached $1B ARR in 2024 and raised $4B from Amazon (now $8B total Amazon investment), making it the best-funded AI safety company.

In 2025-2026, Claude competes primarily against ChatGPT (OpenAI) and Gemini (Google) for both consumer and enterprise mindshare. Claude's strongest differentiation is long context (200K tokens), coding capability, and the trust of regulated industries. Anthropic's partnership with AWS (Bedrock) and Google Cloud gives it enterprise distribution that complements its direct API channel.

## Frequently Asked Questions

### What is Claude?
Anthropic's AI assistant designed to be helpful, harmless, and honest. Excels at long documents, nuanced instructions, and structured outputs.

### What versions of Claude exist?
Opus (most capable), Sonnet (balanced), Haiku (fastest). Available via web app, mobile, and API.

### Is Claude free?
Free tier with Sonnet. Pro ($20/month) adds all models including Opus with higher limits.

### What is Claude's context window and why does it matter?
Claude supports up to 200,000 tokens of context — roughly 500 pages of text — in a single conversation. This allows users to upload entire codebases, lengthy contracts, full research papers, or long conversation histories and have Claude reason across all of it simultaneously. The long context is one of Claude's most distinctive capabilities for enterprise document work.

### How does Claude handle sensitive or confidential content?
Anthropic builds Claude with a Constitutional AI approach, training the model to be helpful while avoiding harmful outputs. Enterprise API users' data is not used for training by default. Claude is designed to decline dangerous requests while remaining useful for nuanced professional tasks, and Anthropic publishes its safety research and model cards publicly.

### Can Claude write and execute code?
Claude can write, explain, debug, and review code across dozens of programming languages. In Claude.ai, the Artifacts feature renders code outputs including HTML, React components, and SVG in a live preview pane. For production code execution, Claude integrates with developer environments via the API or tools like Claude Code (the CLI for software engineering workflows).

### What is Claude's pricing model?
Claude.ai offers a free tier with Claude Sonnet. Pro ($20/month) unlocks higher usage limits and access to Claude Opus. The API is priced per million tokens by model — Haiku is cheapest for high-volume tasks, Sonnet balances cost and capability, and Opus is the most powerful. Enterprise plans include custom limits, SSO, and dedicated support.

### How does Claude compare to ChatGPT for enterprise use?
Claude is generally preferred for long-document analysis, nuanced instruction-following, and structured output tasks, while ChatGPT has broader plugin integrations and a larger consumer user base. Both offer enterprise-grade security. Claude's longer context window (200K tokens vs GPT-4o's 128K) gives it an advantage for tasks requiring reasoning across large amounts of provided material.
