Claude AI

When OpenAI released ChatGPT in late 2022, it grew faster than any app in history. One of the closest competitors to ChatGPT is Claude AI, released in 2023. If you are like us, you’ve wondered what the difference between the two really is. Are they both interchangeable?

Claude and ChatGPT are AI models that provide generative AI chatboxes. This similarity has birthed a Claude vs. ChatGPT debate.

This blog discusses the core differences between the two that affect their functionality and assistance. It also explains when and where to use ChatGPT and Claude respectively.

Introduction to Claude AI and ChatGPT

There has been a division in the world because of AI, with half detesting it and the other half relying on it. No matter which side you’re on, you cannot disagree that Claude and ChatGPT have been helping people with advanced tasks- for free, no less.

  • What is Claude AI?

Claude AI uses a transformer model, that is a form of deep machine learning (ML). Transformer models allow the LLM to connect patterns and prompts in the text or file provided. So when you give Claude a prompt that’s a new concept for it, it will read and find patterns on the internet to give you answers.

Another thing that distinguishes Claude from other LMMs is the Anthropic Constitutional AI. This is a set of guidelines built into Claude so it can avoid AI bias and act ethically, as humans do. Ethical guidelines help AI feel and act more human. It is also trained to use contextual, natural language conversations in the form of text formats.

How many versions of the LM are there?

  • Anthropic’s latest Claude 3 AI models[1] includes Claude 3, Claude 3 Haiku, and Claude 3 Sonnet.

  • Though they are all language-only models, they are not similar in functionality. Claude can write as many as 75 000 words, and then answer questions about it.

  • What is ChatGPT?

GPT stands for Generative Pret-Trained Transformer. OpenAI has basically explained how its LLM works through its name itself. ChatGPT works on an unsupervised training model. This means that the model is given open access to the internet, along with pictures and audio, so it can combine the data to learn.

The “Pre-Trained” in GPT was supposed to be a distinguishable feature for the model, but is no longer relevant since all AI LLMs are pre-trained.

How many versions of the LLM are there?

  • OpenAI provides many versions of GPT LLM and non-LLM models like Whisper speech-to-text and DALL-E image generation.

  • ChatGPT currently offers the GPT-4o, GPT-4, and the GPT-4o mini. All three models have improved public access and knowledge cut-off dates. For example, ChatGPT users can access GPT-4o and GPT-4o mini for free, while GPT-4 is only available to paid users.

  • The three GPT models have different knowledge cut-off dates. For example, GPT-4o and GPT-4o mini have October 2023 as their cut-off, while GPT-4 cut-off is December 2023.

3 Core Features of Claude AI

Adding Claude to your workflow can be very beneficial, no matter your role. It helps with simple programming and coding, or even content writing. Here are a few of its core characteristics:

1. Researching Skills

AI’s most significant contribution is research and information flow. Thanks to its ability to handle complex texts, Claude is a trusted research assistant. Claude can quickly read and summarise large texts, saving research time. But we must be cautious with it and its results because AI isn’t 100% right; always fact-check key findings.

2. Summarising Large Volumes of Text

Claude is most effective when summarising texts like meeting notes, news articles, and legal content. It generates brief, accurate abstracts that keep all the relevant information onboard.

You can summarise text by downloading a file or copying it from your current document section. Claude supports a large number of file formats, including TXTs, CVSs, PDFs, and Docx files. This is important for analysts and researchers, as they frequently have to assess big data.

3. Natural Conversation

Claude also refers to and elaborates on past contributions to keep the focus of the topic in mind. It can answer questions, respond to informal conversations, and offer helpful material.

Using idioms or slang in your prompts does not confuse Claude. Also, Claude always refers to previous conversations and builds on them for the new topic. It can perform a search and respond with any information the user might be seeking or share new information during a conversation. In this case, Claude's AI chat is useful for customer service and marketing.

3 Core Features of ChatGPT

ClaudeAI is good with ethics and conversation, while ChatGPT gives practical information first. Using ChatGPT in your work can help you in these ways:

1. Natural Language Processing (NLP)

Thanks to its NLP skills, ChatGPT can respond to queries like a human. Most of the time, it can interpret your questions and respond in a personal and human manner.

ChatGPT can get proof for your arguments. For instance, your team is deciding between having a knowledge base or live chat as part of the product. Here, you can use this information to convince others that live chat is more sensible if you are a product marketer.

ChatGPT also analyses patterns in discussions. It personalises its responses in a way that is more relevant by analysing previous interactions.

2. Custom GPTs

With ChatGPT, you can create an AI chatbot that has certain capabilities. This is one of the most utilised ChatGPT functions.

For instance, you are building an onboarding partner for your SaaS offering. ChatGPT can assist in creating how to speak with new consumers and as a support chatbot. To embed this strategy, it will use the knowledge base it has accumulated over time.

3. Large Language Expertise

A massive 570 GB dataset from the internet powers ChatGPT. Using all this information, ChatGPT AI speaks 200 different languages. It is one of the best AI copywriting tools. It can define and explain complex, exotic terms in a flash.

Choosing the Right AI Tool: When to Use Claude AI vs. ChatGPT

Claude might be preferable for firms that analyse large amounts of documents. This is because they require a much higher token limit, and their API costs significantly less. Organisations in the supply chain may opt for ChatGPT because it identifies patterns and trends.

Nonetheless, AI and ML can help grow your business, which is why you need to know which one suits you best. Here are some more instances to know when these LLMs can come in handy:

  • When to Use Claude

The Claude Anthropic AI works well for companies that need to process a lot of data. Because it supports over 100,000 tokens, Claude is suitable for financial statement analysis and document examination of legal cases.

Claude AI especially is used in industries that often require the analysis of large documents like reports, contracts, or research papers. Hence, with Claude, a law firm can read through several papers and make decisions in record time.

  • When to Use ChatGPT

OpenAI's ChatGPT is a multimodal system. For example, it can analyse text and images, and will integrate audio and video as well. Hence, ChatGPT is ideal for professional areas like writing and content creation or digital marketing.

For marketing teams that work on multiple platforms and need to generate content for all , ChatGPT can be a real lifesaver. The web access in ChatGPT is an added advantage, as it can even supply real-time information and get new trends.

Conclusion

If your company handles huge documents, Claude might be the best choice for you. This is especially true for businesses in the legal, financial, or medical fields. But if your company needs multimodal features, use ChatGPT.

Remember, ChatGPT works with text, graphics, and real-time web data. It's best for supply chain management and marketing. Although both models are quite valuable, their different advantages suit different businesses' needs.
