The Intelligent
AI for Builders
The world’s most capable AI, purpose-built for seamless application integration. One elegant API unlocks reasoning, vision, coding, and conversation at scale.
Everything you need.
Nothing you don’t.
Claude delivers industry-leading performance across every dimension that matters for production applications — from deep reasoning to instant responses, with safety built in from the ground up.
Extended Thinking
Claude reasons through complex problems step by step, delivering nuanced answers that simpler models can’t match. Ideal for analysis, math, and logic-intensive tasks.
Vision & Multimodal
Understand charts, screenshots, documents, and images natively. Feed Claude mixed content and get unified, intelligent responses.
Tool Use & Agents
Give Claude tools — search, code execution, databases — and let it orchestrate complex multi-step workflows autonomously.
Natural Conversation
The most human-feeling AI available. Claude maintains context, adapts tone, and communicates with warmth, clarity, and nuance.
Streaming Responses
Deliver content token-by-token for a fluid, real-time user experience. Full streaming support with server-sent events and WebSocket integration.
Constitutional Safety
Built on Anthropic’s Constitutional AI research — Claude is trained to be helpful, harmless, and honest. Enterprise-grade safety with nuanced judgment.
import Anthropic from '@anthropic-ai/sdk'; const claude = new Anthropic(); // Simple, powerful, elegant const message = await claude.messages.create({ model: "claude-sonnet-4-20250514", max_tokens: 1024, messages: [{ role: "user", content: "Analyze this customer data" }] }); // Stream responses in real time claude.messages.stream({ model: "claude-sonnet-4-20250514", max_tokens: 1024, messages: [...] }).on('text', text => { process.stdout.write(text); });
Three lines to
production-ready AI
Official SDKs, zero friction
First-class TypeScript, Python, and Java SDKs with full type safety, auto-retry, and built-in streaming support.
npm + pip availableTool use & function calling
Equip Claude with custom tools — databases, APIs, calculators — and let it decide when and how to use them.
JSON Schema definedBatch processing at scale
Process thousands of requests asynchronously with the Message Batches API. Up to 50% cost reduction for offline workloads.
