LLM Routers Explained!!!

LLM routing offers a solution to this, where each query is first processed by a system that decides which LLM to route it to. Ideally, all queries that can be handled by weaker models should be routed to these models, with all other queries routed to stronger models, minimizing cost while maintaining response quality. However, this turns out to be a challenging problem because the routing system has to infer both the characteristics of an incoming query and different models’ capabilities when routing.
To tackle this, we present RouteLLM, a principled framework for LLM routing based on preference data. We formalize the problem of LLM routing and explore augmentation techniques to improve router performance. We trained four different routers using public data from Chatbot Arena and demonstrate that they can significantly reduce costs without compromising quality, with cost reductions of over 85% on MT Bench, 45% on MMLU, and 35% on GSM8K as compared to using only GPT-4, while still achieving 95% of GPT-4’s performance. We also publicly release all our code and datasets, including a new open-source framework for serving and evaluating LLM routers.

Hi 1littlecoder, please excuse me:
Love your videos on AI news! 💡 Here's an idea: Imagine if phone calls used AI like ChatGPT to seamlessly redirect calls, talk in any language, and connect like-minded people in conference calls, similar to Clubhouse. Dial 999, and AI handles the rest, routing to the best human experts available.
Older generations might not use ChatGPT or apps unless it's as easy as dialing 999 and speaking their native language. This system would also provide valuable data to train new LLM models and tune AI agents (data is the new gold!). Do you think AI is ready for this? Would love your thoughts!
Keep up the great work! 🚀

Hi It would be great if you can make a hands on video on this library!

[@1littlecoder]

Great suggestion! Will try soon

[@__________________________6910]

Nice explanation

[@1littlecoder]

Thanks and welcome

[@narasimhasaladi7]

One good thing is we are gaining knowledge ,but the best thing is if u can create some hands on tutorials then it will be more helpfull ,thank you i hope u create hands on tutorials too

What are your views on using reranker and embeddings?

[@MichealScott24]

❤

[@joneskiller8]

Do you think these open-source libraries will become paid subscriptions in the future? If so, what is your opinion on sticking to LangGraph for routing instead of using this library or crew AI? I do understand what RouteLLM is offering is a much richer routing framework.

What if we have big system promp with short query? Will it decide based on complexity?
There can be simple query like hello and how are you and little complex query as conversation move forward.
Would it be possible to switch model at different stage of conversation?
So many questions in one comment but really curious 😃

[@RKWYT1]

Hello Sir I really need your help can you help me out with my shapley value code

[@LiamVDB1]

How does it compare to mixtral 8x22B?
