Anthropic

Anthropic is an AI safety company focused on building reliable, interpretable, and steerable AI systems. Founded by former OpenAI researchers, Anthropic develops the Claude family of AI assistants and pioneered techniques like Constitutional AI (CAI) for aligning AI with human values.

Anthropic's offerings include: Claude models (Haiku, Sonnet, Opus) via API, the Claude.ai consumer product, and enterprise solutions. Their API provides: chat completions, vision capabilities, function calling, and large context windows up to 200K tokens. Anthropic emphasizes safety research alongside capability development.

For AI engineers, Claude models are known for: strong instruction following, nuanced understanding, coding capabilities, and reliability in production. The API experience is similar to OpenAI but with different strengths. Engineers should evaluate Claude for their specific use cases, particularly for tasks requiring careful reasoning, long context, or where safety considerations are paramount.
