ChatGPT Open Source Alternative


OpenAssistant is the ideal open-source replacement for ChatGPT. To provide an exceptional user experience, it combines natural language understanding and reinforcement learning with human Turing review. Users can use OpenAssistant to engage with their systems via a chatbot and automatically obtain information based on their input.

Its unique technique was created by LAION and many individuals from around the world, demonstrating a strong dedication to making this technology accessible to everybody. OpenAssistant will allow individuals to interact more effectively in a variety of contexts where it was previously impossible!


Meta’s OPT-175B is the most recent and cutting-edge open source alternative to ChatGPT. It’s a massive GPT-3 equivalent model with 175 billion parameters that’s available for research after filling out an access form.

It’s not simply its massive size that makes it unique: it can also be used to create catbot-style conversations using natural language processing! Even if you don’t want to build your own chatbot, the thorough performance data from the accompanying OPT paper demonstrates that this cutting-edge technique can help with any type of natural language processing.


BLOOM is a significant milestone for AI researchers since it provides large language models (LLMs) for use on a variety of tasks based on user instructions. BLOOM supports 46 natural languages and 13 programming languages, including Spanish, French, and Arabic, and has 176 billion parameters. Over 1000 researchers and 250+ institutions from 70 countries worked together to create this open-source model! The 117-day run that resulted in its creation was hosted at the Jean Zay supercomputer in Paris, with computing funding totaling €3 million from CNRS and GENCI. BLOOM paves the door for more contributions to AI research by making strong LLMs more accessible than ever before – all of which are free to use!


GPT-NeoX-20B is an innovative open source alternative to the popular GPT ai. It is one of the largest autoregressive models with publicly published weights, with 20 billion parameters. This model was created for tasks like language learning, mathematics, and knowledge-based applications.

Its performance in these tasks has been examined, and it displays excellent results in few shot reasoner abilities, gaining considerably more when compared to similar sized GPT-3 or FairSeq models when evaluated five times. The training and assessment code is now available on Github, making it a publicly available resource for anyone interested in experimenting with this powerful open sourcing alternative for their project needs.


For those looking for a capable open source chatbot, GPT-J 6B is a fantastic choice. This transformer model was created with Ben Wang’s Mesh Transformer JAX and has six billion trainable parameters, making it one of the most powerful open source models accessible.

To use this model, simply enter some text as a prompt, and GPT-J will provide more relevant results than its predecessors. Furthermore, GPT-internal J’s representation of the English language can provide valuable insights into how our language works, which can be important in data extraction tasks. Overall, GPT-J 6B is an interesting possibility for those looking to construct a successful chatbot using open source technology.
