Opus 4.5 is the new best model for RAG
An evaluation of Opus 4.5 inside a real retrieval setup, compared against Gemini 3 Pro and GPT 5.1 across five behaviors that matter for RAG.
Gemini 3 vs GPT 5.1 for RAG
We tested Gemini 3 inside an actual retrieval setup and compared it directly with GPT-5.1 across five areas that matter for RAG.
Embedding models have converged
We compared 13 embedding models across 8 datasets using an LLM judge and ELO scoring. The result: almost all of them perform in the same narrow band.
Best Reranker for RAG: We tested the top models
We benchmarked eight leading rerankers under identical conditions to find which one performs best for real-world RAG pipelines — comparing speed, accuracy, and LLM-judged relevance.
Cohere vs ZeRank: Which Reranker Actually Performs Better?
We compared Cohere v3.5 and ZeRank-1 in a RAG pipeline using a BEIR subset and a custom dataset — analyzing accuracy, latency, and LLM preference.
