Danke Bruder, habe dazu nichts bei der Langchain doku gecheckt.

Love the video! How would you stop (interrupt) streaming with the FastAPI example and ensure that openAI stops generating tokens before it’s done?

When using langchain llms
Is it just a kind of wrapper for the transformer eg like
"""
from transformers import LlamaForCausalLM, LlamaTokenizer

tokenizer =
model =

"""
Can you elaborate on that? My current understanding is that they refer to this for "not openai models"
Thanks and br

do you have code for using a retrievalQAchain to send streaming responses?

phani

Always enjoy your videos. Would love a deep dive on agents. Also is there a way to contact you regarding consulting?

Using astream, the response from the LLM has words that are split for example the word "hippopotamus" comes as 2 chunks "hippo" and "potamus". When creating an app, how to recognize and combine the 2 split parts into a single word for front-end?

The streaming is only by tokens and putting a space inbetween that, how do you remove the space between tokens but keep the space between words though?

hi, can you please explain how can we do this while working with more than one input variable.

Hello,
thank your for your video. How can you remove the wrong space that is displayed ? Is it only on the front you have that?

jeanmarigne

Thanks, would be nice 2 see with opensource llm and streamlit OR gradio as the frontend.

Can we use llama 2 from huggingface and still do the streaming?

Now can use the backend with cloud run, lambda or some serverless function
