Why it matters
- Large context window for full codebases or long docs.
- Used for coding, review, and analysis.
- API and chat product serve different use cases.
Key capabilities
- Extended context (model-dependent) for long inputs.
- Code generation, explanation, and refactoring.
- Tool use and structured outputs via API.
Technical notes
- API: REST (Anthropic API); chat at claude.ai.
- Self-hosted: No.
- License: Proprietary.
Ideal for
- Long-form writing, analysis, and coding tasks that benefit from large context.
- Teams and developers who want an API alternative to OpenAI with strong reasoning.
- Use cases that fit Anthropic's safety and product roadmap (see anthropic.com).
Not ideal for
- Fully local or air-gapped deployment; inference is cloud-only.
- Real-time or very low-latency requirements without tuning; check API docs for limits.
