What is Claude 2?

Claude 2 is the next generation of Anthropic’s conversational AI assistant. Building on Claude’s advanced natural language capabilities, Claude 2 represents a major leap forward in how AI can engage in helpful, harmless, and honest dialog. In this article, we’ll explore what makes Claude 2 unique and how it pushes the boundaries of conversational AI.

Improved Training Methodology

Claude 2 continues to be trained using Constitutional AI, Anthropic’s pioneering self-supervised learning technique. The key advancements focus on massively scaling the size and diversity of training datasets to improve Claude 2’s understanding of natural conversation and world knowledge.

Some key training improvements include:

• Broader Datasets – Claude 2 is trained on 10X more data, sourcing public domain conversations across many international languages and domains. This develops more universal conversational intelligence.
• Longer Conversations – Most training dialogs for Claude 2 consist of 10+ turn conversations rather than single statements or queries. This allows more complex, contextual dialog capabilities to emerge.
• Higher Resolution – Claude 2 models use significantly larger parameters and machine learning architectures. This enables more nuanced generation of intelligent, relevant dialog.

Combined, these training data improvements increase Claude 2’s conversational depth and ability to gracefully continue dialogs with consistent personality and narrative.

Enhanced Reasoning

In addition to improved dialog training, Claude 2 incorporates more advanced reasoning, memory, and comprehension capabilities through a combination of techniques:

• Latent Knowledge – Claude 2 maintains latent knowledge graphs about the world, current events, personal attributes and other topics to better ground its responses.
• Long Term Memory – Key entities, facts and conversational themes are explicitly tracked and recalled over the full course of a dialog.
• Reading Comprehension – Claude 2 can read documents provided during a conversation and incorporate that knowledge into a coherent dialog.
• Logical Reasoning – Causal, quantitative and symbolic reasoning abilities allow Claude 2 to make logical inferences and explain its conclusions during a conversation.

Together these enhancements enable Claude 2 to follow conversations requiring diverse reasoning skills most humans intuitively possess.

Specialized Domain Expertise

While Claude 2 excels at general conversation, its training can also be tailored and extended to particular domains. Some capabilities unlocked:

• Customer Support – Claude 2 can be efficiently trained on archives of customer support tickets and dialog. This allows it to directly assist customers with common issues and questions.
• Medical Expertise – With the proper data permissions, Claude 2 can learn medical knowledge to serve as an AI assistant for tasks like patient triage and diagnostic support.
• Subject Matter Tutoring – Training sets of textbooks, online courses and lectures enables Claude 2 to converse about specialized topics and tutor others.
• Product Expert – Product documentation, wikis, manuals and other collateral can teach Claude 2 to have expert-level knowledge on proprietary systems or services.

Targeted transfer learning unlocks Claude 2’s potential for many vertical applications requiring deep domain expertise and specialized conversation skills.

Responsible AI

While rapidly advancing its conversational capabilities, Anthropic continues to ensure Claude 2 adheres to the highest standards of ethical, helpful, honest AI:

• Truthful and Consistent – Constitutional AI inherently minimizes generating false or contradictory information during conversations.
• Sensitive Content Filtering – Claude 2 has enhanced sensitivity classifiers fine-tuned on massive data to identify potential harms.
• User Privacy Protection – No personal user data is ingested by the models or used for training. Conversations utilize anonymized identifiers.
• Ongoing Oversight – Anthropic pledges continuous auditing of Claude 2’s capabilities and broad testing for potential harms as the technology evolves.

These commitments ensure Claude 2 will set a new bar for AI safety while rapidly expanding its conversational intelligence over time.

Private Beta Access

Anthropic is currently conducting private beta testing of Claude 2 capabilities with select partners and collaborators under NDA. If you’re interested in gaining early access, please contact: claude2@anthropic.com

We look forward to feedback from early adopters to steer Claude 2’s progress before a wider general availability release.

The Future of Conversational AI

Claude 2 represents a major evolution of natural dialog capabilities for Anthropic’s Constitutional AI. But it’s just one step on the path towards fully realizing helpful, harmless and honest conversational intelligence. With Claude 2, we move closer to:

• Contextual Assistant – Following any conversation naturally.
• Trusted Companion – Discussing any topic meaningfully.
• Personalized Tutor – Explaining any concept clearly.
• Creative Collaborator – Brainstorming new ideas proactively.
• Empathetic Humanity – Relating conversationally and emotionally.

The journey continues, but Claude 2 marks a significant milestone. We’re excited to see where the future of AI and human conversation leads.

Conclusion

Claude 2 leverages orders of magnitude more training data, state-of-the-art models, and enhanced reasoning to achieve unprecedented conversational intelligence. Early beta access is available for select partners.

Constitutional AI ensures these powerful advancements will maintain beneficial, safe, and honest dialog aligned with human values. Claude 2 represents the next generation, but there are even more ambitious steps to come on the path towards beneficial artificial general intelligence.
