Anthropic
AI safety company that builds Claude, a large language model focused on being helpful, honest, and harmless with strong reasoning capabilities.
What is Anthropic?
Anthropic is an AI safety company that builds Claude, a large language model that competes with GPT-4 and Gemini.
Founded in 2021 by former OpenAI researchers Dario and Daniela Amodei, the company focuses on Constitutional AI - training models to be helpful, honest, and harmless through explicit principles rather than just human feedback.
Most builders use Claude through the web interface at Claude.ai, the API, or tools like Cursor. Claude 3.5 Sonnet (their latest model) is particularly strong at coding, analysis, and following complex instructions. It has a 200K token context window, which means it can process entire codebases or long documents in one go.
The API uses usage-based pricing. Free tier available at Claude.ai with message limits. Pro plan is $20/month for higher limits.
