OpenAI API error langchain error: context_length_exceeded

I just setup the OpenAI API key and I am getting the error langchain error: context_length_exceeded even when my query is only 2 characters. How is this possible? Where do I set the context length?

Isn’t a ChatGPT plus account supposed to come with some free OpenAI API credits? How do I get those? I bought credits to get started faster but if there are free credits with ChatGPT Plus I’d like to know how to use them.

Hi! Welcome to the forum!

Nope! It’s currently independent of whether you have a chat plus account or not. You can go to to see if you have any credit.

What model did you use?

In any case, that’s a langchain issue - langchain (depending on your setup) injects a ton of stuff into your context. It’s also possible that it’s a misconfiguration. In LangChain.

I figured it out, thanks. It’s a bug in the application I’m using. It has a max context length setting and if that setting is higher than the model supports even if your query is very small it breaks the API implementation.
