Anthropic's Claude 4 release in 2026 represents a significant step forward for business AI. Here is everything you need to know to evaluate, adopt, and deploy it effectively.
What is Anthropic?
Anthropic is an AI safety company founded in 2021 by former OpenAI researchers Dario and Daniela Amodei. Unlike OpenAI's consumer-first approach, Anthropic built Claude with enterprise reliability and safety as primary objectives. Their Constitutional AI training method teaches the model principles rather than just patterns — resulting in more consistent, predictable, and trustworthy outputs for business use.
