Claude

Claude is a family of AI assistants developed by Anthropic, designed to be helpful, harmless, and honest. Available at claude.ai and through a comprehensive API, Claude provides state-of-the-art capabilities in reasoning, coding, writing, and analysis across multiple modalities including text and vision. The platform prioritizes safety and transparency, operating under Anthropic status as a public benefit corporation dedicated to responsible AI development.

Models and Capabilities

Claude offers three model tiers designed to address different performance and cost requirements:

• Opus 4.8 is the most capable model in the lineup, excelling at complex reasoning, long-horizon agentic coding, and high-autonomy tasks. It features a 1M token context window, 128k token maximum output, and adaptive thinking that allows the model to adjust its reasoning depth based on task complexity.
• Sonnet 4.6 delivers the best balance of speed and intelligence. It supports both extended thinking and adaptive thinking capabilities, with a 1M token context window and 64k token maximum output at competitive pricing.
• Haiku 4.5 is the fastest model with near-frontier intelligence, offering a 200k token context window and 64k output at the lowest cost, making it ideal for high-volume tasks that require quick responses.

All current Claude models support text and image input, multilingual capabilities, and vision features. Extended thinking, adaptive thinking, and priority tier options are available across select models.

Products and Integrations

Beyond the core AI assistant, Anthropic offers several specialized products built on the Claude platform:

• Claude Code is an agentic coding tool that helps developers write, debug, and review code directly from the terminal. It understands entire codebases and can perform multi-step coding tasks autonomously.
• Claude Cowork enables collaborative work with AI assistance for teams and organizations, allowing multiple users to work alongside Claude in shared workspaces.
• Claude Security provides AI-powered security analysis and defensive cybersecurity capabilities, including specialized tools for vulnerability detection and secure code review.
• Claude Platform offers enterprise-grade deployment options on AWS, Google Cloud, and Microsoft infrastructure with regional compliance support.

Claude is also available through browser extensions for Chrome, Slack, and Microsoft 365, integrating directly into existing workflows.

Safety and Research

Anthropic operates as a public benefit corporation with a core mission of AI safety research. The company publishes a Responsible Scaling Policy that governs how it evaluates and deploys increasingly capable models. Transparency is a priority, with detailed disclosures about model capabilities, limitations, and safety evaluations. Claude models are trained using Constitutional AI techniques that promote helpfulness while systematically reducing harmful outputs and bias.

Developer Access and Pricing

Claude is accessible through multiple channels for different development needs. The Claude API provides direct integration with flexible pricing, prompt caching for reduced costs on repeated queries, and batch API options for processing large volumes of requests. Enterprise customers can deploy Claude through Amazon Bedrock, Google Cloud Vertex AI, and Microsoft Foundry. API pricing ranges from $1 per million input tokens for Haiku to $5 per million input tokens for Opus, with output pricing ranging from $5 to $25 per million tokens depending on the model selected.
