 Even though `text-chat-davinci-002-20221122` is back up again, it seems like it's constantly overloaded and returns a 429 error. It's likely that OpenAI only dedicated a small amount of resources to this model to prevent it being widely used by the public. Additionally, I've heard that newer versions are now access-locked to OpenAI employees and partners, so it's unlikely that we'll be able to find any workarounds until the model is officially released.

-This is an implementation of [ChatGPT](https://chat.openai.com/chat) using the official ChatGPT raw model, `text-chat-davinci-002`. The model name `text-chat-davinci-002-20230126` was briefly leaked while I was  inspecting the network requests made by the official ChatGPT website, and I discovered that it works with the [OpenAI API](https://beta.openai.com/docs/api-reference/completions). **Usage of this model currently does not cost any credits.**

+#### About Bing's GPT-4 version of ChatGPT
+An experimental client for Bing's GPT-4 version of ChatGPT is available in [`BingAIClient`](src/BingAIClient.js). It works much like ChatGPT, but it's powered by GPT-4 instead of GPT-3. For more information on its capabilities and limitations, see [this Reddit comment](https://www.reddit.com/r/ChatGPT/comments/10xjda1/comment/j7snwxx/?utm_source=reddit&utm_medium=web2x&context=3).

 As far as I'm aware, I was the first one who discovered this, and usage of the model has since been implemented in libraries like [acheong08/ChatGPT](https://github.com/acheong08/ChatGPT).
 
 The previous version of this library that used [transitive-bullshit/chatgpt-api](https://github.com/transitive-bullshit/chatgpt-api) is still available on [the `archive/old-version` branch](https://github.com/waylaidwanderer/node-chatgpt-api/tree/archive/old-version).
 
-By itself, the model does not have any conversational support, so this library uses a cache to store conversations and pass them to the model as context. This allows you to have persistent conversations with ChatGPT in a nearly identical way to the official website.
