About Claude
Claude is an AI assistant developed by Anthropic, the AI safety company founded by former OpenAI researchers including Dario Amodei and Daniela Amodei. Named after Claude Shannon, the father of information theory, Claude is designed to be genuinely helpful, harmless and honest — values baked into its training via Constitutional AI, Anthropic's proprietary safety methodology. Claude is consistently rated as the most thoughtful, nuanced and instruction-following AI assistant among frontier models.
The Claude family spans three tiers: Haiku (fast and cost-efficient), Sonnet (balanced performance and speed) and Opus (maximum capability). Claude 3.5 Sonnet, the current flagship, achieves top-tier scores on coding benchmarks including SWE-bench and HumanEval, outperforming GPT-4o on reasoning and nuanced instruction following in independent evaluations. The 200,000-token context window — equivalent to a 500-page book — enables Claude to analyse entire codebases, legal documents, academic papers or financial reports in a single session.
Claude's writing quality is consistently rated higher than competitors by professional writers, editors and content teams. It produces prose that sounds genuinely human, maintains consistent voice across long documents and follows complex stylistic instructions with exceptional accuracy. For long-form work — essays, reports, book chapters, technical documentation — Claude is the preferred choice among professional writers.
The Artifacts feature in Claude.ai generates interactive code, SVG diagrams, React components and documents that render live in the interface, making it exceptionally useful for developers building prototypes. Claude is available via the web app, iOS and Android apps, the Anthropic API, AWS Bedrock, Google Cloud Vertex AI and Azure AI Studio — providing the broadest enterprise deployment options of any frontier model.
Claude's Constitutional AI training means it maintains safety boundaries more reliably than competitors while being less prone to unnecessary refusals on legitimate requests — a balance that makes it popular for enterprise deployments in healthcare, legal, finance and compliance-heavy industries. Anthropic provides enterprise-grade SLAs, data processing agreements and regional data residency options.
