Introduction
Artificial intelligence (AI) chatbots have advanced rapidly in recent months. Two of the most advanced chatbots are Claude 2 by Anthropic and GPT-4 by OpenAI. This article compares these two AI systems in depth.
Overview of Claude 2
Anthropic, an AI company, developed Claude 2 as an upgraded version of Claude 1. Utilizing “constitutional AI” techniques, Claude 2 is designed to adhere to ethical guidelines such as the United Nations Universal Declaration of Human Rights.
Some key capabilities of Claude 2:
- Can summarize long texts up to 75,000 words. It was tested by Forbes Advisor to summarize a 58-page insurance policy document.
- Scored high on legal, math, coding, and language exams. It got 76.5% on the Bar exam and over 90th percentile on GRE reading/writing.
- Improved safety over Claude 1.3 – it is 2x less likely to produce harmful responses.
- Multilingual – can converse in over 10 languages.
- Can write essays, stories, code, and solve equations.
- Can explain its reasoning and thought process behind answers.
Accessing Claude 2
Claude 2 is currently only available in beta in the UK and US. Users worldwide can access it using a VPN like NordVPN or Surfshark.
Features of Claude 2
Some key features and capabilities of Claude 2:
- Long text summarization – can summarize texts up to 75,000 words
- PDF reading and summarizing – can quickly parse key info from PDFs
- Coding assistance – can help with Python, SQL, CSS, JavaScript, etc.
- Math and equations – scored 88% on grade school math test
- Essay and creative writing
- Multilingual – speaks 10+ languages conversationally
- Explains reasoning and thought process behind responses
Overview of GPT-4
GPT-4 is the latest AI model developed by OpenAI. With 1.8 trillion parameters, it is the largest AI model ever created. GPT-4 is open source and free for developers to use.
Features and Capabilities of GPT-4
Key features and capabilities of GPT-4:
- Human-like text generation – can produce very convincing human-like content
- Creative writing like stories, poems, lyrics, etc.
- Code generation from natural language descriptions
- Document summarization – can summarize long texts
- Language translation – supports multiple languages
- Image, video, and audio generation – can generate multimedia content

Training Data
Claude 2’s Training Corpus
- Claude 2 was trained on a variety of data including books, websites, academic papers, and social media.
- The model learns from both structured and unstructured text data.
- Claude 2 continues to learn from new data, allowing it to improve over time.
GPT-4’s Training Dataset
- GPT-4 was trained on vast amounts of internet text data.
- Its dataset contains over 1 trillion words from books, Wikipedia, news articles, and more.
- The huge dataset enables GPT-4 to generate very human-like text.
Language Capabilities
Claude 2’s Language Skills
- Claude 2 can converse in over 10 languages including English, Chinese, Spanish, French.
- It has strong abilities to understand natural language and provide human-like responses.
GPT-4’s Multilingual Strengths
- GPT-4 has been trained extensively in multiple languages.
- It shows impressive multilingual skills in languages like English, Chinese, Arabic, Spanish, and more.
- GPT-4 can translate between languages and respond appropriately based on context.
Ethics and Safety
Claude 2’s Focus on AI Ethics
- Claude 2 incorporates AI safety practices like red teaming.
- Anthropic specially designed Claude 2 to avoid harmful, dangerous, or unethical output.
Limitations of GPT-4’s Ethical Capabilities
- GPT-4 does not have explicit safeguards against generating problematic content.
- OpenAI relies on human monitoring to filter out concerning GPT-4 outputs.
- More work needs to be done to improve GPT-4’s safety mechanisms
Conclusion
Claude 2 and GPT-4 are leading conversational AI models with advanced capabilities. Claude 2 places emphasis on ethics while GPT-4 has greater scale and performance. Both can provide assistance in writing, coding, math, summarization, and more. The choice between them depends on specific user needs and preferences. But both Claude 2 and GPT-4 represent major leaps forward for AI.
