Gemini Embedding 2 Leads 2026 RAG Benchmarks: Perfect 4K-32K Scores, 5 Modalities, 1605 ELO

Milvus Blog·medium signal

Gemini Embedding 2 leads the 2026 embedding benchmark with 1605 ELO, winning more head-to-head matchups than any model. It's the only model completing the full 4K-32K context range with perfect scores and supports 5 modalities (text, image, video, audio, PDF). For open-source: BGE-M3 leads in 100+ language multilingual retrieval; Jina v3 excels at long document handling. Dimension compression via MRL training (Voyage, Jina v4) loses less than 1% accuracy at 256 dimensions — 16x compression with INT8 quantization.
