Claude vs ChatGPT vs BARD [2023]

Claude vs ChatGPT vs BARD. Artificial intelligence (AI) has seen rapid advancements in recent years, with systems like Claude, ChatGPT, and BARD demonstrating impressive natural language abilities. These AI assistants can hold conversations, answer questions, and generate human-like text on a wide range of topics.

But how exactly do these leading systems compare? In this in-depth article, we’ll break down the key differences between Claude, ChatGPT, and BARD across several categories to help you understand the unique strengths and weaknesses of each platform.

Overview of Claude, ChatGPT, and BARD

First, let’s briefly introduce each system:

Claude – Developed by Anthropic, Claude is promoted as an AI assistant focused on being helpful, harmless, and honest. It aims to provide truthful information and avoid potential harms through safety constraints.

ChatGPT – Created by OpenAI, ChatGPT (Generative Pre-trained Transformer) is known for its conversational abilities and human-like responses. It can answer follow-up questions and admit when it doesn’t know something.

BARD – BARD is Google’s experimental AI chatbot that is designed to provide high-quality responses by grounding conversations in real-world information. It aims to be truthful, up-to-date, and safe.

Now let’s do a deeper comparison across key categories:



  • ChatGPT has been trained on data up until 2021, so its knowledge ends in that year. It cannot provide up-to-date information on recent events.
  • BARD has access to more current information from the internet, making it more knowledgeable about the world today.
  • Claude has a more limited knowledge base than ChatGPT and BARD right now, as it is newer and less extensively trained.

Conversation Ability

  • ChatGPT excels at conversational ability – it can understand context and have back-and-forth chats better than the other two.
  • BARD aims to improve conversational ability through a technique called Contextual Augmentation, but it is not yet at ChatGPT’s level.
  • Claude has good conversational skills like answering follow up questions, but struggles with longer conversations.

Length of Responses

  • ChatGPT can generate very long, detailed responses without repeating itself. Its responses regularly exceed 1000 words.
  • BARD generates slightly shorter responses than ChatGPT, ranging from a paragraph to around 800 words.
  • Claude’s responses tend to be relatively short so far, often just 1-5 sentences.


  • BARD is the fastest system, providing instantaneous responses in many cases.
  • ChatGPT also responds quickly, thoughsometimes takes 5-10 seconds to generate longer responses.
  • Claude is the slowest, taking 10+ seconds to generate most responses. This is because of Claude’s focus on safety and truthfulness.


  • ChatGPT shows remarkable creativity, able to generate poems, jokes, songs, code, and more based on prompts.
  • BARD has strong abilities to produce creative writing, though its poetry and song lyrics are not yet on par with ChatGPT.
  • Claude has limited creative capabilities right now, as creativity often conflicts with truthfulness.

Accuracy and Factual Knowledge

  • BARD aims to provide factual accuracy by relying on external knowledge sources, though errors still occur.
  • ChatGPT frequently makes up plausible-sounding but incorrect or nonsensical answers when its knowledge runs out.
  • Claude places truthfulness as its top priority. It will admit ignorance rather than speculate incorrectly.

Staying Up-To-Date

  • BARD can provide relatively recent information on current events, people, and technology by using web search.
  • ChatGPT’s knowledge cutoff in 2021 means it lacks awareness of recent world events and discoveries.
  • Claude’s knowledge lags a bit behind the present day, like ChatGPT, as keeping fully up-to-date poses challenges.

Admitting Ignorance

  • Claude AI and BARD are willing to admit the limits of their knowledge and say “I don’t know” rather than fabricating information.
  • ChatGPT will confidently provide convincing but false responses when it lacks knowledge about a topic.


  • Claude aims to give consistent answers on factual topics each time it’s asked.
  • Both ChatGPT and BARD may provide contradictory responses when asked the same question multiple times.

Bias, Ethics, and Safety

Potential for Harm

  • BARD has some content filtering in place but has exhibited concerning biases in early testing. Google will need to proactively address potential harms.
  • ChatGPT has generated harmful, biased, or unethical content in some cases, as it lacks constraints.
  • Claude is designed with strong safety measures to avoid generating dangerous, illegal, or unethical output.

Data Sources

  • The training data used can introduce biases. ChatGPT was trained on a very large but undiverse dataset scraped from the internet.
  • BARD may reduce biases through more varied data sources and human feedback during training.
  • Claude used a smaller, high-quality dataset specifically constructed to avoid amplifying undesirable biases.


  • Anthropic plans to release Claude’s full training dataset and model details to allow external auditing, setting a new standard of transparency.
  • OpenAI has not revealed the full extent of ChatGPT’s training data or model details.
  • Google has provided limited information so far on BARD’s inner workings.

Usefulness and Reliability

Usefulness for Intended Purpose

  • For open-domain conversations, ChatGPT provides very impressive user experiences through its articulateness and conversational skill.
  • For assisting with specific tasks, Claude has an advantage by optimizing for being helpful, harmless, and honest.
  • The usefulness of BARD chatbot interactions is still to be determined as the system gets more robust testing.

Reliability and Consistency

  • Claude aims for maximum reliability by adhering to its purity constraints and avoiding speculation.
  • ChatGPT’s responses will vary widely based on slight prompt differences and across chat sessions.
  • BARD strives for consistency, but may still be prone to some variation based on how it interprets and retrieves information.


  • Claude’s commitment to truthfulness, safety, and transparency make it one of the more trustworthy AI systems.
  • BARD must be vetted much more before considering it a trustworthy source of information.
  • ChatGPT’s plausibly incorrect responses make it entertaining but not trustworthy without verification.


Fine-Tuning Capabilities

  • ChatGPT allows for fine-tuning on custom datasets to adapt its knowledge, though this requires technical skills.
  • BARD is not publicly available yet, so its fine-tuning potential remains unknown.
  • Claude does not support fine-tuning at launch, but future customizability is planned.

User Controls

  • Claude provides transparency settings allowing users to view its confidence scores and how it generates responses.
  • ChatGPT does not have visibility into how it derives responses or its confidence in answers.
  • BARD may eventually incorporate some transparency settings, but currently offers users no visibility.

Integration with Other Systems

  • As an API, ChatGPT can integrate with other applications and systems with developer effort.
  • BARD aims to integrate seamlessly into Google’s existing products and services.
  • Claude can integrate with any system that interacts through natural language.

The Bottom Line

Claude, ChatGPT, and BARD represent groundbreaking AI achievements, each with unique strengths. ChatGPT dominates in conversational ability and creativity but falters on truthfulness. Claude prioritizes safety, responsibility, and honest usefulness above all. BARD aspires to factuality but must prove itself through extensive testing.

There is no definitively “best” system; each has merits based on the specific priorities and use cases desired. As AI capabilities rapidly evolve, we can expect steady improvements across all models in knowledge, reasoning, and judgment.

Continued progress will depend on keeping ethics, safety, and transparency front and center – avoiding the pitfalls of uncontrolled technological advancement. If thoughtfully developed and applied, these AI systems can provide immense value to humanity. But guiding them responsibly along that path will require vigilance, care, and compassion.
