⚡️Improve AI requests

[AntoLC]

Feature Request

We can improve the AI requests with a few steps:

• Translation seems to be an easy task, we can use meta-llama/Llama-3.1-8B-Instruct, the request will be faster
• add a maxToken to the call API, to do so we have to calculate the amount of token in our request, see https://github.com/belladoreai/llama-tokenizer-js or tiktoken (python)
• we can improve the frontend message errors by displaying what is the real problem ?
• We can stream the response, by streaming the response we will be able to display content the the user gradually.
