Why do some responses message content start with ```json?

[Foxalabs]

Hi and welcome to the Developer Forum!

It’s an artefact from the json mode training, the best thing to do is to strip ```json ``` from your output via regex.

See:

Gpt-4-1106-preview messes up function call parameters encoding

For any users who have switched from gpt-3.5-turbo to one of the newer models, and are making use of the “json mode” the json output will typically be in markdown format and have top and tail markdown markers, i.e. ```json with a closing triple backtick at the end. You can remove this with a regex parser like this : response.content = response.content.replace(/```json\n?|```/g, '');
