The first open source AI chatbot in the spirit of ChatGPT has arrived, and it has come at a particularly useful time. ColossalChat is a powerful alternative that uses a RHLF pipeline similar to the OpenAI GPT-4 model powered by ChatGPT, and is available for immediate use.
ChatGPT, of course, remains the ultimate AI chatbot and has plenty of work to do. But just now I tried to log in and found that it is full and therefore not available. This is a common problem with the service. ColossalChat, on the other hand, is wide open and ready to use for free.

This new AI chatbot can write code, intelligently respond to requests and talk like OpenAI’s solution. You can try it for free at chat.colossalai.org, and you don’t even need to sign up or create an account.
A quick test of ColossalChat’s safeguards revealed that it has some, but is more lax than ChatGPT. He didn’t want to talk about bombs, but he shared tips about cheap cigarettes.
According to a Medium post by one of its developers, Yang You, ColossalChat’s Coati large language model is based on LLaMA, Meta’s open-source large language model, then refined to respond in a way that is more similar to ChatGPT. In fact, You exclaims that ColossalChat is “the closest project to the original technical route of ChatGPT.”
LLaMA can be used directly if you can build the project on your computer. However, its results will not be as attractive as those of ChatGPT or Colossal.
RHLF is an essential feature of ColossalChat and ChatGPT. This means reinforcement learning from human feedback, similar to how animals are taught to perform tricks. When the AI’s response is appropriate, it is rewarded, which helps the network understand human preferences.
It is too early to know if ColossalChat is comparable to the last release of ChatGPT, which used GPT-3.5 and could only process text. The latest OpenAI update brings multi-modal input, allowing images to be uploaded to help visually inform the chatbot about what you’re trying to do or the question you’re asking.
Microsoft’s BingChat is another alternative to ChatGPT, and uses GPT-4 for text input and replies. Bing Chat can now also generate images, through a feature called Bing Image Creator.
ColossalChat is unlikely to surpass ChatGPT in breadth or capabilities or in popularity, but it’s good to have alternatives, especially when ChatGPT reaches capacity.
