What it does

Claude is an AI assistant developed by Anthropic. It stands out for complex reasoning, long-form writing, and code generation. Available via web (claude.ai), mobile app, API, and developer tools (Claude Code, IDE extensions).

In 2026, Anthropic keeps three primary models active: Opus 4.7, Sonnet 4.6, and Haiku 4.5. All support 200K–1M token context. Opus 4.7 scored 64.3% on SWE-bench Pro — the highest among publicly available models — making it the leading coding model of 2026.

Claude’s focus areas: professional writing, coding, document analysis, research synthesis, and long-context tasks. Unlike ChatGPT, it does not generate images, audio, or video natively — it only understands text and images.
