| Jina AI Embeddings | OpenAI Embeddings | |
|---|---|---|
| Type | Open embedding models + API | OpenAI embedding API |
| Created | 2023 | 2022-01 |
| Latest release | jina-embeddings-v5-omni (nano and small; 2026-05-07); reranker jina-reranker-v3.5 (2026-07-27) | v3.39.0 (2026-10-26) — openai (PyPI) |
| License | mixed — most recent open-weight models CC-BY-NC-4.0 (v3, v5-omni, v5-text, clip-v2, colbert-v2, reranker-v3; commercial licence via Elastic); jina-embeddings-v4 under the Qwen Research License (its model card says the initial CC-BY-NC-4.0 label was an error); some older models Apache-2.0 | proprietary; SDKs Apache-2.0 |
| GitHub | no dedicated embeddings repo (weights on Hugging Face); jina-ai/MCP ~841 stars, jina-ai/reader ~11.9k | openai/openai-python — ~32k stars, last commit 2026-10 (official Python SDK) |
| Pricing | Hosted API: prepaid token packages with a free trial key and optional auto-recharge (pricing model since 2025-05-06); also on AWS SageMaker and Microsoft Azure; Jina On-Prem containers sold through Elastic Sales | text-embedding-3-small $0.02 per 1M tokens; text-embedding-3-large $0.13 per 1M tokens |
