"Ran a bunch of experiments with Graph RAG (KET-RAG) on multi hop question answering. Turns out **retrieval** is basically **solved**, the answer is in the context 77 to 91% of the time. The **bottleneck is reasoning**: 73 to 84% of wrong answers come from the model failing to connect the dots, not f..."
🎯 Model Improvements • Reasoning vs Retrieval • Graph Compression
💬 "the finding that 73-84% of failures are reasoning not retrieval is honestly the most important takeaway here"
• "the graph compression piece is interesting too - cutting context by 60% without extra llm calls probably helps more than ppl realize"

"Hey everyone,
When building systems around modern open-source LLMs, one of the biggest issues is that they can confidently hallucinate or state an incorrect answer with a 95%+ probability. This makes it really hard to deploy them into the real world reliably if we don't understand their "overconfid..."
