Even if I could make use of it, I wouldn't, because I don't write proprietary code that only works on one AI Service Provider. I use only LangChain so that all of my code can be used with any LLM.

My app has a simple drop down box where users can pick whatever LLM they want to to use (OpenAI, Perplexity, Gemini, Anthropic, Grok, etc)

However if they've done something worthy of putting into LangChain, then I do hope LangChain steals the idea and incorporates it so that all LLM apps can use it.
