Jina Embeddings v3
Jina AI
DISCONTINUED. Jina AI's open text embedding model (September 2024), a 570M-parameter model with task-specific LoRA adapters (retrieval, clustering, classification) and long-context support. It offers strong price-performance and multilingual retrieval, self-hostable or via the Jina API. Jina AI's own model page marks it deprecated in favour of newer models.
Strengths
- Task-specific LoRA adapters (retrieval, clustering, classification)
- Long-context support for full documents
- Strong multilingual retrieval
- Excellent price-performance (~$0.02/1M via API)
- Self-hostable open weights
Caveats
- DISCONTINUED - Jina AI marks it deprecated on its own model page
- Jina AI points to jina-embeddings-v5-text-small
- CC-BY-NC weights (commercial use via the Jina API)
- Below the very top commercial models on peak MTEB
- Self-hosting requires embedding infrastructure

Pricing
Open weights under CC-BY-NC 4.0 (non-commercial). Commercial use via the hosted Jina API, sold as token packs: $50 per 1B tokens (~$0.05 per 1M tokens) or $500 per 11B tokens (~$0.045 per 1M); new API keys get free trial tokens. Jina changed pricing on May 6th, 2025 (the old $20/1B, ~$0.02/1M pack is no longer sold). Self-hosting outside AWS SageMaker/Azure requires a separate commercial licence (sold by Elastic since August 10, 2026, priced annually).
