Claude vs ChatGPT

How Claude and ChatGPT Work: Underlying Technology Explained

To understand what sets Claude and ChatGPT apart, we first need to explore how these AI chatbots actually work at a technical level:

Claude’s Constitutional AI Approach

Claude is an AI assistant created in 2022 by Anthropic, an AI safety startup founded by former OpenAI and Google researchers. Claude’s foundation is what Anthropic calls Constitutional AI.

Constitutional AI is Anthropic’s novel training methodology intended to inherently align an AI assistant with human values like helpfulness, harm avoidance, and honesty. This allows Claude to generate information that is trustworthy, ethical, and beneficial to humans by design.

Claude achieves this through a technique called self-supervised learning. The model is trained to predict its own future helpful and harmless actions, allowing it to learn human ethics and social norms entirely from unlabeled text data. Claude is also trained to openly admit when it does not know something to avoid false information.

The result is an AI that proactively avoids generating dangerous, unethical, harmful, or illegal content thanks to its Constitutional AI framework. This gives Claude an advantage in safety and reliability compared to unconstrained generative AI models.

ChatGPT’s Reinforced Learning Approach

ChatGPT was released by OpenAI in November 2022 and quickly went viral due to its impressively human-like conversational skills.

Under the hood, ChatGPT utilizes a transformer-based neural network architecture called a large language model (LLM). Specifically, it uses a 175 billion parameter LLM trained using reinforced learning from human feedback.

Here’s how it works:

The model is trained on a massive dataset of online text and conversations to learn patterns in human language. It is then fine-tuned using a trial-and-error reinforcement learning technique by having it practice conversations with human trainers.

The trainers provide positive or negative feedback to guide the model towards more sensible, relevant, and engaging dialogue. This allows it to dynamically improve through conversational practice rather than static supervised learning.

While this technique results in remarkably natural dialogue, it focuses on mimicking human conversational patterns in a general sense rather than embedding ethical principles like Claude.

Now that we understand how each chatbot works under the hood, let’s see how their capabilities compare in real world use.

Capability Comparison: Claude vs ChatGPT’s Strengths and Weaknesses

Claude and ChatGPT have distinct sets of strengths and weaknesses across key criteria like conversational ability, knowledge, accuracy, creativity, and more.

Natural Conversation Ability

  • ChatGPT excels here. Thanks to its reinforced learning from human feedback, ChatGPT has mastered the art of friendly, fluid, and impressively human-like conversation. It provides incredibly engaging responses with personality and wit.
  • Claude converses less naturally. While perfectly capable of intelligent discussion, Claude’s responses tend to be more stiff, robotic, and focused on providing factual accuracy over conversational engagement.
  • Verdict: For the most seamlessly natural dialogue, ChatGPT is superior. But Claude offers honest, substantive responses even if less entertaining.

Factual Knowledge

  • Claude offers more up-to-date knowledge. Since ChatGPT was trained only up until 2021, its knowledge abruptly ends before current events and the last 1-2 years. Claude contains much more up-to-date knowledge on topics like COVID-19, politics, technology, and more.
  • ChatGPT has more broad general knowledge. Given the sheer size of its training data, ChatGPT contains more general world knowledge – it’s just outdated for recent specific events and facts.
  • Verdict: Claude is stronger for current factual knowledge, while ChatGPT has an advantage in broad general knowledge.

Accuracy and Truthfulness

  • Claude prioritizes truth and accuracy. Thanks to its Constitutional AI training, Claude avoids guessing when unsure and will acknowledge gaps in its knowledge base to provide truthful answers. Even at the cost of admitting ignorance, it values accuracy.
  • ChatGPT favors confidence over truth. Since ChatGPT is incentivized to create sensible-sounding responses through its training approach, it will confidently provide convincing but entirely incorrect or nonsensical answers when uncertain, displaying an unconscious bias towards pleasing the user over truth and accuracy.
  • Verdict: For applications where accuracy and truth matter more than slick responses, Claude is safer and more reliable.

Ethics and Safety

  • Claude reduces risks of harmful content. Claude’s training methodology proactively minimizes risks of unethical, dangerous, illegal, or biased content. This makes it safer for uses like medical advice, moderating user-generated content, and avoiding propaganda.
  • ChatGPT has higher risks of abuse. While ChatGPT does have certain safety protocols in place, it was not trained with the explicit goal of ethical alignment. This has resulted in it generating concerning outputs like racist, sexist, or violently dangerous content when tested. Special caution is advised.
  • Verdict: For any use case where ethics, safety, and avoiding harm is critical, Claude’s Constitutional AI approach makes it a more trustworthy choice over ChatGPT.


  • ChatGPT dominates creative applications. When it comes to creative generation like crafting poems, short stories, jokes, lyrics, fictional narratives and more based on prompts, ChatGPT displays far stronger performance. Its training specifically for conversational engagement transfers well to entertaining creative uses.
  • Claude prioritizes factual responses. While Claude can generate multi-paragraph essays or bullet points when asked, its strength lies more in coherent and accurate explanatory text. For creative fiction or poetry, it lacks ChatGPT’s creative spark.
  • Verdict: For any form of creative generation from poems to fictional stories, ChatGPT is superior thanks to its reinforced learning from human feedback. But for informative articles and explanations, Claude has the edge.

By examining their contrasting strengths and weaknesses, we can start to get a sense of which types of use cases each AI assistant is better optimized for based on their capabilities. Next we’ll explore some of their ideal real-world applications.
