The verdict
Gemini Embedding 2 appears in 3 AI-ranked categories — best position #2 for multilingual embedding api for semantic search.
Best overall multilingual retrieval quality, supporting 100+ languages and cross-language search, with flexible 128–3072 dimensions and native text, image, audio, video, and PDF embeddings; strongest default when quality and multimodal headroom matter.
Grok Strong multilingual MTEB performance (top ranks reported ~69.9), native multimodal (text+images/video/audio) in unified space for advanced semantic search, low latency/cost via Gemini API/Vertex AI, excellent for practitioners needing cross-modal or enterprise-grade reliability.
Gemini Native multimodal support (text, image, audio, video) in a single model, strong multilingual retrieval, and deep integration with the Google Cloud / Vertex AI enterprise ecosystem.
Where Gemini Embedding 2 falls short, per the models
- GPT Its 8,192-token limit is restrictive for long documents compared with 32K-context rivals.
- Gemini Tied closely to the Google Cloud/Vertex AI infrastructure, where API setup, procurement, and management are more complex than developer-oriented standalone APIs.
- Grok Not purely text-focused; multimodal limits (e.g. PDF page caps, audio/video duration) and API dependency may not suit pure text or self-hosted needs.
Top alternatives per the models: Cohere Embed 4 · Qwen3-Embedding · BGE-M3 · Gemini Embedding
First native unified multimodal embedding across text, images, video, audio, and documents in one vector space; top cross-modal retrieval (out
Gemini Highly scalable, cost-efficient general-purpose API featuring a large 8k token limit, native video and audio embedding capabilities, and turnkey GCP vector search integration.
GPT Very inexpensive image embeddings, flexible 128–3072 dimensions, more than 100 languages, and one unified space spanning text, images, PDFs, audio, and video; a near-tie with Cohere when broad modality coverage matters
Where Gemini Embedding 2 falls short, per the models
- GPT Newer and less independently proven on real image-retrieval workloads, with only six images per request and an 8K-token ceiling
- Gemini Shows poor accuracy on highly specialized domain visual layouts and is deeply dependent on the Google Cloud platform ecosystem.

The strongest raw video understanding available — hours of footage in a single long-context prompt, timestamped answers, direct YouTube URL ingestion, and Gemini Flash pricing makes per-video analysis extremely cheap; Vertex's multimodal embeddings cover the vector-search side. Wins the near-tie with Twelve Labs if you'd rather assemble your own pipeline and pocket the cost savings.
GPT Near-tied with Nova on retrieval merit, with native video/audio embeddings, a shared cross-modal space, strong multilingual coverage, and convenient Gemini API or Vertex AI access.
Where Gemini Embedding 2 falls short, per the models
- GPT Its 120-second video-input limit and preview maturity make production-scale long-video indexing substantially more DIY.
- Claude There is no managed video search index — you build ingestion, chunking, embedding storage, and retrieval yourself, and re-querying the same footage burns tokens unless you engineer context caching carefully.
