Is ChatGPT Open Source?



| Updated on:

ChatGPT is an Artificial intelligence chat service, created by OpenAI. It has received massive recognition around the world from users for its features and capabilities to develop human-like content. ChatGPT utilizes open-source data and allows developers to use the model in their application through OpenAI’s API which has resulted in many users wondering Is ChatGPT Open-Source?

If you are wondering the same question then you’ve arrived at the right place. In this article, we will discuss OpenAI’s ChatGPT and whether the popular AI chatbot is open-source or closed-source. In addition, we have also mentioned the top open-source alternatives of ChatGPT.  

Is ChatGPT Open Source?

Is ChatGPT Open Source?

No, ChatGPT is not Open Source as the AI chatbot’s source code is owned by OpenAI. ChatGPT is based on OpenAI’s GPT language model, which is a private API. Although, ChatGPT still utilizes Open source data. 

Is GPT open source?

GPT is developed by OpenAI which is not open-source. OpenAI’s GPT is a language model which is a private API which means GPT is not open-source. Although, if you are an AI developer and are looking to implement GPT in your own projects then you won’t be able to do so. 

But, OpenAI does allow developers to employ the moderated version of the language model, GPT-3 API. Developers can use GPT-3 as an API, but it’s important to keep in mind it will not have access to the source code and only documentation. Users can also join the waitlist to gain access to OpenAI’s latest language model GPT-4. 

Is Open ai open source?

OpenAI’s ChatGPT was created as an open source which is why it was named as “Open” AI, non-profit company to serve as a counterweight to Google, but now it has become a closed source, maximum-profit company effectively controlled by Microsoft. 

Is ChatGPT API open source?

ChatGPT is not an Open-source model however, it is available through OpenAI’s API, which allows the developers to utilize the model in their applications without the need to download and train the model themselves. The API allows users to use the model for various natural language tasks such as content generation, translation, answering complex queries, and much more. 

OpenAI has recently released the GPT-4 language model which is available as an API for developers to build services and applications and users can join the waitlist by providing their personal details such as Name, email, organization ID, and more. Although ChatGPT is not open-source, OpenAI provides a variety of methods for developers to work with the model, such as the API and pre-trained weights along with insight through research papers that can help users understand the models and their capabilities. 

Is ChatGPT Free to Access?

The basic version of OpenAI’s chatbot is available for free use. But to utilize ChatGPT API users need to purchase tokens for GPT-3.5 turbo users (learn about ChatGPT Turbo mode) need to pay $0.002/1K tokens.  You can access ChatGPT 4 for Free here.

The pricing of GPT-4 API starts from $0.03 per 1000 “prompts” tokens with 8K context lengths, with the sampled tokens priced at $0.06 per 1000 tokens.

The price of 32K context length begins at $0.06 per 1000 prompt tokens. While the sampled tokens contain a price range of $0.12 per 1000 tokens. 

What are Open-Source ChatGPT Alternatives?

Here are some of the Open-source ChatGPT Alternatives, which can be used by users: 


OpenChatkit is an Open-source chat model which was trained using about 43 million instructions and sustains reasoning, knowledge, multi-turn conversations, and generative answers. It was launched under an Apache-2.0 license which provides users complete access to model weight, source code, and training datasets since the aim is community-driven.

This model utilizes about 20 billion parameters and is designed for instructions and conversations. OpenChatkit is great at performing various tasks such as summarizing, classification, generating tables, and dialog. 


Vicuna is another great open-source alternative to ChatGPT. This model has been trained using fine-tuning LLaMA on users’ conversations which was gathered using Which is a community site that allows users to share their ChatGPT conversations.

This model contains more than a 90% quality rate in comparison to other AI chatbots such as Google Bard and OpenAI’s ChatGPT. Making Vicuna one of the top open-sourced models when looking for a feature parity to ChatGPT. 


GPTall is a community-driven assignment that has been introduced using a wide range of curated corpus of written texts for assistant interactions such as stories, codes, depictions, and multi-turn dialogue. To enable the open-source model the company has provided model weights, datasets, training code, and data curation processes. 

In addition, a quantized 4-bit version of the model was developed which can run on users’ laptops. Users can even use a Python client to run the model inference. 


Bloom is another open-source LLMS that is moderately on par with OpenAI’s ChatGPT. It is capable of performing a variety of tasks in 46 languages and 13 programming languages. It uses more than 176 billion parameters. Bloom’s development was corresponded by BigScience, which is a vibrant open research cooperation to launch LLMs publicly. 


Alpaca is an open-source language model that claims it can compete with OpenAI’s chatbot ChatGPT. It is small and can be reproduced by anyone and it even showcases similar abilities as OpenAI’s ChatGPT and Microsoft’s Bing Chat. The fine-tuning of Alpaca was done by LLaMD 7B model on 52K instruction-following demos.

Wrapping Up

ChatGPT is not an Open-source model. However, developers can still utilize OpenAI’s API and use the model in their applications. But if you are looking for Open-source alternatives to ChatGPT, then above we have mentioned all the top, Open-source models that you can utilize as an alternative to OpenAI’s ChatGPT.
