Thankyou for making amazing video on Bedrock 🎉

[rachitsharma]

@rahul thanks for the video - can we use our local text files as an input to the LLM like llama2 that can also be deployed on local?

[onestopzz]

Hi, Llama 2 Chat models are showing unavailable in all the regions. In which region did you access this model? Are there any alternative models available in AWS to use for this chatbot?

[techtomorrow]

wow this something I wanted !! can you tell me which model in AWS is good for finetuning the docs and giving the result very quick.
and could you please make one video on that .

This is great, thanks for sharing. Looking for CHATBOT with AWS Amazon Bedrock & Agent + KB, Claude, Langchain, and Streamlit

Straight out of the gate those responses are not being parsed correctly, the model is continuing after the stop token, hence the Human response and the Llamas back and forth.

[khandetanvikram]

Can you share the git repo for the session code

[indrajitg]

Great video Thanks.
What if I want to integrate or build such chatbot using bedrock for my website ? (not streamlit as frontend) any suggestions or recommendations ?

[iterator]

How do we add Contextual info on this model such that Chatbot can answer contextual questions as well generic answers ?
Thanks

I am getting below error
The class `Bedrock` was deprecated in LangChain 0.0.34 and will be removed in 0.3. An updated version of the class exists in the langchain-aws package and should be used instead. To use it run `pip install -U langchain-aws` and import as `from langchain_aws import BedrockLLM`.

Having trouble in authentication " Could not load credentials to authenticate with AWS client. Please check that credentials in the specified profile name are valid" although I set the tokens properly, any solutions ?

[draaken]

is it mandatory to configure the aws cli for access key and secret key? Can't we put the key credentials in code or in .env file. and pass it to Bedrock function?

[cosmicfluke]

I dont see in the code where you added the credentials. But these are not free APIs correct. So where do you do that.? even if you are accessing it from OS you still have to do that using code correct?

[varun_tech]

Is there a way to trim the response. To avoid the unnecessary answers "The Human : and AI: "part

[premymn]

Which model is good to parse word and pdf documents in bulk

[VISHVANI]

Thank you, What is the Infra requirement for above demo?

[kunalpinyani]

How can we use Bedrock to query data from Database without calling API?

[dangollayan]

Is there free trial/tier? for your demo, how much does it cost?

[saisampath]

Sir..I am getting an error that "You don't have access to the model with the specified model ID."

[maruthisrinivas]

Why is the LLm model's Output containing the questions and answers for which we didnt ask also, Example : Human : Thats understandable, can you tell me a joke?, Here we have not asked that specific question also
