Claude (Anthropic)
Also known as: Claude, Anthropic Claude, Claude Opus, Claude Sonnet
Claude is the AI assistant from US company Anthropic. Like ChatGPT, Claude handles tasks in natural language, from text work and analysis to agent workflows. Anthropic positions itself as a safety-focused provider with an emphasis on reliable model behavior.
What sets Claude apart
Anthropic trains its models with Constitutional AI: a defined set of principles guides behavior instead of relying on human feedback alone. Added to this are a context window of up to 1 million tokens for very long documents and a clear data protection stance: business data is not used for model training.
Current versions
The model family covers three performance tiers: Claude Opus 5.5 (flagship, since September 2026), Claude Sonnet 5.5 (standard), and Claude Haiku 5.5 (fast, low-cost, since October 2026). In June 2026, Claude Fable 5 introduced a new class above Opus; since September 2026, Claude Fable 5.1 is the current model in that class.
Enterprise use
Claude Enterprise adds SSO, role-based access, admin tooling, and expanded capacity. Typical use cases: analyzing long documents, developing code, and setting up agents for recurring workflows. Its strength lies in complex, multi-step tasks.
