About Anthropic API (Claude)

Anthropic's Claude API gives developers and enterprises access to the Claude family of models — Haiku, Sonnet, and Opus — each balancing speed, capability, and cost differently. Claude 3.5 Sonnet has consistently ranked at the top of coding and reasoning benchmarks while remaining faster and more cost-efficient than comparable alternatives. The 200K token context window is one of the industry's largest, enabling processing of entire codebases, lengthy legal documents, or complete book manuscripts in a single prompt. Vision capabilities handle image analysis, chart interpretation, and document processing. Anthropic's Constitutional AI training approach produces models that are notably less likely to produce harmful outputs, making Claude the preferred choice for safety-sensitive applications. Tool use and JSON mode support structured application development. The Batch API reduces costs for high-volume offline workloads. Enterprise tiers include dedicated capacity, compliance certifications, and audit logging.
