Underlying Technology of Claude 2

Claude AI 2 showcases cutting-edge AI research to achieve safe and beneficial conversational AI:

Large Language Models

Claude 2 leverages a class of natural language AI models called LLMs (large language models) as its base. LLMs like GPT-3 and Claude’s foundation model are trained on massive text data sets to gain strong language comprehension and generation skills.

Anthropic developed Claude’s proprietary LLM architecture focused on harmless, honest, and helpful traits. With 12 billion parameters, it is one of the most capable public LLMs available today while optimized for safety.

Constitutional AI

This novel technique developed by Anthropic instills beneficial characteristics in Claude 2 aligned with human values. Constitutional AI acts as a series of constraints on the LLM to filter, amend, and guide its behaviors appropriately.

Key Constitutional AI methods include preference learning, information filtering, social modeling, and feedback systems. Together, they shape Claude 2’s knowledge, qualities, and conversation tactics dynamically for good outcomes.

Machine Learning

Like other AI systems, Claude 2 continuously improves through machine learning techniques based on ongoing experiences. Anthropic trains and updates Claude 2 using reinforcement learning, natural language inference, and other algorithms.

By learning from human conversations and feedback, Claude 2 progressively enhances its language, reasoning, social intelligence, and world knowledge. Regular updates by Anthropic incorporate the latest learnings.

Knowledge Curation

In addition to machine learning, Anthropic carefully curates quality data sources to expand Claude 2’s knowledge base safely. These validated information sources augment what Claude 2 acquires through conversational experience.

Moderation and fact-checking ensure only accurate, ethical information enters Claude 2’s knowledge, adhering to the principles of Constitutional AI. This knowledge enables Claude 2 to provide helpful information to users.

Ethical Research

Anthropic prioritizes developing AI safely, using techniques like technical amplification control, constitutional training, and red teaming to identify potential risks or harms early.
