Qwen3 Embedding or E5: which embedding model to pick
Both families are multilingual, handle Russian, run on a CPU and allow commercial use: Qwen3 Embedding under Apache 2.0, E5 under MIT. Qwen is newer and broader: releases in 2025-06 and 2026-01, a reranker included for reordering results before answering, and VL versions that search images, slides and screenshots; it is also in Ollama. Microsoft's E5 stopped at multilingual-e5-large-instruct in 2024-02, but its range starts at 33M, which matters when you are squeezing into weak hardware or indexing a large corpus. Building RAG from scratch, Qwen is the sensible pick; if an E5 setup already works for you, there is no reason to replace it.
