Overview
Anthropic develops the Claude models and pioneered the MCP (Model Context Protocol) open standard for connecting agents to tools and data. Claude is widely used for coding, long-document reasoning, and reliable multi-step tool use, and powers Anthropic's own coding agent. The mid-2026 lineup is Claude Opus 4.8, Sonnet 4.6, and Haiku 4.5.
Key Features
- Claude Opus, Sonnet, and Haiku model tiers
- Strong agentic tool use and long-context reasoning
- Author of the MCP open tool-connection standard
- Powers the Claude Code coding agent
Role in the Agentic AI Stack
A leading 'brain' for agents, especially coding and tool-heavy workflows. Anthropic's MCP is now a cross-vendor standard used throughout this landscape.
