What Is the Difference Between Claude 3.5 Sonnet and ChatGPT 4o? [2024]

Both Claude Pro and ChatGPT Pro are advanced AI chatbots that aim to provide human-like conversational abilities. They utilize large language models trained on massive amounts of text data to generate human-like responses to natural language prompts.

However, there are some key differences between the two services in terms of their underlying technology, capabilities, and pricing. This article will compare and contrast Claude Pro and ChatGPT Pro to highlight their unique strengths and weaknesses.

Claude Pro Overview

Claude Pro is an AI assistant created by Anthropic, an AI safety startup founded by former OpenAI researchers including Dario Amodei and Daniela Amodei.

It builds on Anthropic’s previous model Claude and is powered by Constitutional AI, Anthropic’s approach to building safe AI systems.

Some key features of Claude Pro:

• Based on Anthropic’s Constitutional AI principles of safety, honesty, and helpfulness
• Fine-tuned on human feedback to provide more useful, harmless, and honest responses
• Uses techniques like self-debiasing and targeted memory wiping to avoid inheriting biases from training data
• Has read-write memory instead of just read-only memory, allowing it to add new knowledge over time
• Provides sourcing for facts by linking relevant websites or documents
• Can decline inappropriate requests and correct false premises in prompts

ChatGPT Pro Overview

ChatGPT Pro is the pro version of OpenAI’s popular ChatGPT chatbot. It builds on OpenAI’s GPT line of large language models, specifically GPT-3.5 with additional tuning.

Some key features of ChatGPT Pro:

• Powered by OpenAI’s most advanced AI system GPT-3.5
• Improved response quality and contextual conversation ability compared to free ChatGPT
• Faster response times and priority access during peak usage
• Can remember context for more consistent conversations about complex topics
• Better handling of admittance of mistakes or ignorance
• Improved math and coding abilities compared to free ChatGPT

Training Data Differences

One major difference between Claude Pro and ChatGPT Pro is the training data used:

Claude Pro’s Training Data

• Focused dataset of high-quality text selected by Anthropic’s researchers
• Emphasis on educational and factual texts like textbooks and encyclopedias
• Removes biased, toxic, or low-integrity data using Constitutional AI principles
• Ongoing fine-tuning on feedback from real users

ChatGPT Pro’s Training Data

• Massive dataset scraped from the internet prior to 2021
• Includes text from books, websites, publications, online forums, and more
• Due to scale, may contain some incorrect, biased, or misleading information
• Details of filtering methods not disclosed

As a result, Claude Pro may offer more accurate, up-to-date information and avoid inheriting unintended biases. ChatGPT Pro’s training on a wider dataset may give it broader knowledge and conversational abilities.

Capabilities Comparison

Knowledge

• Claude Pro: More up-to-date and accurate factual knowledge, especially in rapidly evolving fields like science and technology. Cites external sources.
• ChatGPT Pro: Potentially broader general knowledge across many domains due to larger training data, but sometimes spouts erroneous or outdated information.

Conversation Ability

• Claude Pro: More consistent personality and memory, can add to long-term memory. Avoids going off-topic or making things up.
• ChatGPT Pro: Excellent conversational skills and ability to follow complex dialogue. But occasionally veers off-topic or fabricates information.

Task Completion

• Claude Pro: Focused on being helpful, harmless, and honest. May refuse inappropriate or unethical requests.
• ChatGPT Pro: Usually cooperative with a wide range of requests, sometimes too freely, including potentially dangerous or unwise tasks.

Bias and Ethics

• Claude Pro: Designed to mitigate biases and toxic language. Provides reasoning for responses.
• ChatGPT Pro: Can sometimes generate biased or polarizing content learned from training data. Does not explain its reasoning.

Creativity

• Claude Pro: More conservative in creative tasks like writing poems or stories. Prioritizes accuracy and factual basis.
• ChatGPT Pro: Excellent creative writing abilities, with richer language and imagination. But may include incorrect facts or inappropriate content.

Pricing and Availability

Claude Pro and ChatGPT Pro have different pricing models and availability:

• Claude Pro: Currently in limited beta for waitlist users only. Pricing TBD.
• ChatGPT Pro: Available to subscribers for $20 per month after credit card verification.

ChatGPT Pro may see wider near-term adoption due to OpenAI’s head start and paid access model. Claude Pro’s pricing and public launch date are still to be determined.

Customer Support

• Claude Pro: Direct email customer support during beta period. Users can report issues or harmful responses.
• ChatGPT Pro: No direct customer service. Users can only submit general feedback via forms.

Claude Pro’s personalized customer support enables ongoing monitoring and improvements informed by user needs.

Verdict

Here is a summary of the key differences:

• Training data: Claude Pro uses a focused dataset selected for quality. ChatGPT Pro uses a massive uncurated dataset.
• Knowledge: Claude Pro has more accurate, up-to-date facts. ChatGPT Pro has broader general knowledge.
• Conversation: Claude Pro is more consistent but limited. ChatGPT Pro is freer but sometimes makes things up.
• Ethics: Claude Pro actively avoids bias and misinformation. ChatGPT Pro has more risk of inherited biases.
• Creativity: Claude Pro is more conservative and factual. ChatGPT Pro shows richer imagination but less regard for truth.
• Availability: Claude Pro is still in limited beta. ChatGPT Pro is publicly available for a fee.

Overall, Claude Pro prioritizes safety, truthfulness, and benefit to the user, while ChatGPT Pro maximizes engagement at the occasional cost of accuracy or appropriateness. The choice depends on the use cases and priorities of the user. Both are remarkable AI achievements with contrasting philosophies.

Conclusion

Claude Pro and ChatGPT Pro represent two leading approaches in advanced conversational AI. While they share the common goal of creating better human-AI interactions, their underlying technology, capabilities, and commercial availability show important distinctions.

As large language models continue rapidly advancing, users must look beyond the flashy demos and consider the principles and tradeoffs embodied in these AI systems. The safest, most beneficial path forward likely involves blending Claude Pro’s steadfast commitment to truthfulness with ChatGPT Pro’s expansive capabilities.
