Letting users switch between LLMs on a public Streamlit app. Aimed for a simple, zero-cost dev setup: 1. No LLM API keys needed. 2. Uses only standard dependencies like openai and , even for Claude/PaLM. Playground URL:

@LangChainAI Shoutout to @nolangclement for fixing @LangChainAI support!

@LangChainAI @nolangclement And to @litbid for setting up the model switcher

@streamlit @LangChainAI woah this is so great, are you storing the login in session state? or is this connecting to another db somewhere? I work at Streamlit and am in the middle of trying to figure out a payments+authentication component if you want to try that out

@streamlit @LangChainAI Login is being stored in session state at the end of the OAuth flow: Sure! Though I'm handling payments on now, which is working well.

@alonsosilva @streamlit @LangChainAI Looks awesome, Alex!

@LangChainAI Uses OAuth PKCE (proof of key code exchange) to allow users to bring their own model choices to the apps they use. Docs:
