Claude
Anthropic's assistant, strongest on long documents and agentic coding
Best for:codinglong documentsagentsanalysis
Claude is Anthropic's assistant, built on the Opus, Sonnet, Haiku, and Fable model tiers. Every current tier except Haiku ships a 1M-token context window at standard pricing with no long-context premium, which is what makes it the common default for long-document analysis, repository-scale coding, and long-horizon agents.
