Use all the reasoning/test-time compute you want, even the best LLMs are stuck with information frozen at training time. Read up on our latest technique for KPI-driven self-improving LLMs in our latest blog: crossingminds.com/blog/closing-t… @Crossing_Minds #LLM #AI #RAG #RAGSys
It's time to rethink the MTEB benchmark. When picking embeddings, what works for search isn't always what works for #RAG. Read about our proposal for a better benchmark for RAG+ICL embeddings here: reddit.com/r/MachineLearn… #ICLERB #LLMs
Do you clerb? ICLERB! Introducing the In-Context Learning Embedding and Reranker Benchmark (#ICLERB)! It evaluates retrieval models for #LLM in-context learning, based on downstream task performance, not text similarity. 📖: arxiv.org/abs/2411.18947 🏆: huggingface.co/spaces/crossin…
I just posted #ClaudeFrancois to @Reddit /r/MachineLearning, would appreciate an upvote! 👍 reddit.com/r/MachineLearn… #GenAI #CodeReview #LLM #Anthropic #Claude #RAG #RAGSys

I don't get it, how is "baiting him into angry rants" a good thing? She just set him up to deliver his campaign messaging. These same "angry rants" are exactly what has him tied in the polls. Not enough convincing rebuttals. I don't see how this was a win at all.
"I have *concepts* of a plan" I'm using that one 😂
I'm glad we're feeling good here, but how can you allow someone to vilify immigrants that way and get away with it? It's not enough to fact-check or smirk. Expose the hatred behind his lies. Unite us in our humanity. Don't laugh.
Meta Llama 3 is out now and available on Replicate. This language model family comes in 8B and 70B parameter sizes, with context windows of 8K tokens. The models beat most other open source models on industry benchmarks and are licensed for commercial use. Try them here 👇
