Key Features

✨

Constitutional AI

Anthropic has developed a proprietary training framework for its AI systems that incorporates ethical guidelines for the operation of those systems; this makes the AI systems that use Claude more reliable and controllable than standard LLMs.

✨

Hybrid Reasoning (Claude 3.7)

Users of Anthropic's AI systems can set the amount of time between rapid responses and extended step-by-step reasoning, allowing them to balance the speed of the response against the accuracy of the response.

✨

Model Control Protocol (MCP)

The Model Control Protocol (MCP) developed by Anthropic is a widely accepted protocol for controlling AI agents used in enterprises and has been downloaded by users of the MCP over 97 million times per month. In addition, Anthropic provides pre-configured servers for the MCP.

✨

Responsible Scaling Policy

Before releasing a version of Claude that exceeds the capability threshold, Anthropic delays the release of that version until it has developed robust safety measures for that version of Claude.

🔒

Built-in Safeguards

To minimize misinformation and bias in the output generated by its AI systems, Anthropic allows users to adjust the behavior of the AI systems to fit the needs of the organization that is deploying the system.

🏛️

Frontier Research Integration

Finally, Anthropic deploys all of the latest research in interpretability, alignment and red-teaming directly into the production models of Claude.
