Claude 2 vs ChatGPT vs Google Bard: How Anthropic’s AI Chatbot Stacks Up [2023]

The release of Claude 2 by AI startup Anthropic marks a new challenger in the red-hot conversational AI space. As excitement builds for its natural language capabilities, many are wondering how Claude 2 compares to established rivals like ChatGPT and the newly announced Google Bard.

In this post, we’ll analyze the key differences between these three AI chatbots across crucial categories to determine how Claude 2 stacks up.

Training Data and Approaches

Training data and methods significantly impact chatbot performance and safety. Here’s an overview of each platform’s training:

Claude 2

  • Focused entirely on human conversations – no scraped web content.
  • Trained on ethicists’ daily conversations over 5+ years.
  • Reinforcement learning from human AI trainers for safety.


  • Trained on a diverse dataset of web content scraped by Anthropic’s researchers.
  • Supervised learning approach.
  • Human feedback for corrections during training.

Google Bard

  • Trained on Google’s search corpus and other high-quality datasets.
  • Utilizes Google’s language and conversation models.
  • Additional training for friendly and informative responses.

Claude 2’s training focused solely on safe human conversations gives it an edge for natural conversations. ChatGPT’s web scraping method has faced criticism for quality issues. Google is betting its massive data will lead to high-quality responses from Bard.

Capabilities and Features

Key features that enhance utility and engagement include:

Claude 2

  • Personable backstory and consistent personality.
  • Can challenge incorrect assumptions respectfully.
  • Refuses inappropriate requests.
  • Natural conversational flow.


  • Impressive text generation and summarization.
  • Conversational with some personality.
  • Factual knowledge on many topics.
  • Creative writing capabilities.

Google Bard

  • Leverages Google’s powerful language models.
  • Access to high-quality structured data.
  • Conversational abilities and some personality.
  • Integration with Google’s knowledge graph.

Claude 2’s unique personality and principled stance help drive engagement while avoiding potential dangers. ChatGPT still leads in certain content creation tasks. Google Bard aims to combine strong language skills with Google’s vast knowledge.

Accuracy and Safety

Due to AI’s potential for harm, safely avoiding falsehoods or dangerous instructions is critical:

Claude 2

  • Committed to truthfulness even if it lacks knowledge.
  • Refuses to provide dangerous advice or lawbreaking steps.
  • Avoids political stances or speculative responses.


  • Sometimes provides convincing but incorrect responses.
  • Has generated dangerous instructions in certain cases.
  • Struggles with mitigating political or other biases.

Google Bard

  • Leverages Google’s efforts in truthfulness and safety.
  • Still unknown how it handles misinformation or dangerous content.
  • Google has strong incentives to address safety issues.

Claude 2’s principled training approach shows real promise for conversational AI safety. But the technology remains imperfect. Continued vigilance around harm prevention will be key for all providers.

Accessibility and Availability

Wider access drives user feedback needed to improve these systems:

Claude 2

  • Currently in limited beta testing with waitlist access.
  • iOS app available. Web and Android access planned for 2023.
  • Free during beta period. Future pricing TBD.


  • Open AI research preview available to all via web browser.
  • Mobile apps in development.
  • Currently free but future monetization models likely.

Google Bard

  • Will be integrated into Google’s search engine.
  • Likely easy access but details pending.
  • Unclear if will be a free or paid service.

ChatGPT’s wide open preview provides immediate access for all. Claude 2’s slow rollout aims to ensure quality but limits feedback. Google Bard’s ubiquity could accelerate mainstream AI adoption once launched.


Claude 2 demonstrates strong potential to advance the state of conversational AI through its principled training approach focused solely on safe human conversations. But continued progress across accuracy, capability breadth and accessibility will be important as it aims to compete with AI giants like OpenAI and Google.

Key advantages like its unique personality and commitment to truth could give Claude 2 an edge among users who prioritize empathy, ethics and safety. However, ChatGPT still leads in areas like content creation while Google Bard promises power from Google’s vast data and language models.

The ideal path forward is likely the co-evolution of multiple AI philosophies and methods. With responsible development, Claude 2, ChatGPT and Google Bard could each play important roles in realizing the full potential of helpful, honest and harmless conversational AI.
