Langflow makes it easy to create AI applications without writing a single line of code.
In this video we will compare agents to chains, and build our first agent chatbot.

Apologies for the scratchy audio at certain points in the video. I only noticed this during editing and didn't want to delay getting a video out to you guys.

Leon, I'm a huge fan of your tutorials! Your explanations and simple demonstrations have completely transformed my understanding of AI. Thank you so much for sharing all your amazing AI tutorials. I truly appreciate your hard work and dedication!

[edgecrushr]

Huge fan of your videos (todays discovery). Hope to see more Langflow tutorials.

My favorite langchain learning channel because it's so efficiently explained. And I follow practically all AI tutors. Channel is very underrated at this point but it will exponentially grow its subs I'm sure.

Leon, any thoughts on the limit of the number of tools?
Meaning, would a model malfunction if ALL tools were added🤔

I heard another tutor say it would slow it down because the code would be too large.. but I'd like to hear it from you before I believe that.

Thanks for your work.

Keep going! Very good videos really practical! Hug from portugal

[karthikeyakuncham]

want more videos from you on langflow.

Can you explain how to make a custom tool and thank you

[C.Radchaneeporn]

very informative video, Thank you so much !

[thecooler]

what is the difference in connecting Calculator to a new openAI node instead of the existing one? does using a separate openAI node give it its own conversation instance?

[TheShierl]

Great Video Series Leon! I have started playing with Langflow, wondering if it is only meant to create chatbots? My use case is feeding data into a LLM (i.e. 100 Products from a list) enrich it via the LLM and then write the results back to the list. If possible, can you do a video how to support this, writing output back to a list? Keep on the great work!

[altonjones]

Great content as always Leon - have you found any way to manage API keys in Langflow, like env file we would normally use in VS code?

[vava-bw]

Leon, quick question : Can we cite source URL link after every answer to flowise and Langflow?

[musumo]

Hey another great one. look forward to the next langflow. Very interesting after flowise. I do like to see whats going on at the backend! Can I ask does langflow support API calls into other apps e.g. botpress? If so whats the easiest way to do this. I can do this in flowise via POST but not sure in langflow. Am a low coder! Thanks a lot

[АртемКиреев-рн]

Thank you for the tutorial! By the way, do you happen to plan on making a video about AutoGPT in Flowise or LangFlow? It would be very timely, as there is absolutely no precise information anywhere on how to use it.

I also have several mistakes whem tyring to run my application:

1. Error: Could not parse LLM output: `Hello! How can I assist you today?`
2. Error: One output key expected, got dict_keys(['output', 'intermediate_steps'])

Any ideas why and how to solve? Thank you!

Thanks for this tutorial. It is very usefull.

One question: when I click on "chat icon" my screen shows only the chat, there isn´t that left part with options (input variables). What do I need to do?

[gankam]

o you think doing a short video to compare flowise and langflow would be a good idea?

[maverick]

can you also provide multi-agent examples with local gpt4all/huggingface llm's (including one for the Calculator)? The OpenAPI examples are all not feasible for professional usage (data privacy etc.)

[jhncnnr-sec]

Please do more videos on Langflow and how to incorporate chatbot into website

[CarlosChang]

Very good video! is it possible to create different type of agents and chain them? for example create Agent "Chef" that is really good at answering cooking questions and Agent "Hotel" which can answer any question regarding Hotel question. Chain them and have a bot that can be really good at both... this would make an amazing video! looking forward to it!
