Claude
Anthropic's family of AI models known for long context windows, strong reasoning, and instruction-following capabilities.
How It Works
Claude is built by Anthropic and comes in several tiers: Claude Haiku 4.5 (fast and cheap), Claude Sonnet 4.5 (balanced), Claude Opus 4.5 (previous flagship), and Claude Opus 4.6 (most intelligent, 1M token context). Claude models are accessed via Anthropic's Messages API and support vision, function calling (tool use), and structured outputs.
Claude's standout feature is its massive context window. Claude Opus 4.6 can process up to 1 million tokens in a single request, roughly 2,500 pages of text. This makes it the go-to choice for tasks involving entire codebases, long legal documents, or extensive research corpora. Claude also powers Claude Code, Anthropic's CLI tool for AI-assisted software development.
For production apps, Claude Haiku 4.5 offers excellent value for straightforward tasks. Claude Opus 4.6 supports adaptive thinking with configurable effort levels (low, medium, high), allowing you to balance cost against reasoning depth per request.
