[research] Which embedding model should I use for RAG or code search in 2025?

For self-hosted multilingual retrieval use Qwen3-Embedding or BGE-M3; for API-first code/retrieval use OpenAI text-embedding-3-large or Cohere Embed v4. Always benchmark on your own queries and documents because MTEB leaderboard rank does not transfer directly to private corpora.

Journey Context:
The embedding landscape is crowded with Apache/MIT models \(BGE-M3, Qwen3-Embedding, Jina v5\) and API models \(OpenAI, Cohere, Gemini, Voyage\). BGE-M3 remains the budget self-hosted default and supports sparse\+dense\+multi-vector; newer Qwen3-Embedding and Jina v5 trade slightly more compute for better multilingual accuracy. Matryoshka truncation is now standard, so generate at full dimension and truncate later.
