Jina AI

What Jina AI is

Jina AI supplies search components for teams building applications with language models. Its offerings include embeddings, rerankers, Reader, and small language models, with access through an API, the web, or self-hosted software. Reader turns a supplied URL into clean text for LLM, retrieval-augmented generation, and agent systems; it can also search the web and return five results with their URLs and content. The v5 omni embedding models place text, images, audio, video, and PDFs in a shared vector space. Reranker v3 and v3.5 compare candidate documents using listwise scoring in one forward pass.

The listed integrations include MongoDB, Qdrant, Pinecone, Weaviate, Milvus, LlamaIndex, Haystack, LangChain, and Dify. Model deployment is listed for AWS SageMaker, Microsoft Azure, and Google Cloud. Free API keys for Embeddings and Reranker allow 100 RPM and 100,000 TPM; paid keys allow 500 RPM and 2,000,000 TPM. Embedding context limits vary by model from 8,192 to 32,768 tokens. Inputs above a model's limit return an error unless truncation is enabled. Jina AI says it is SOC 2 Type 1 and Type 2 compliant, and its Embeddings FAQ says API requests, inputs, and outputs are not used to train its models.

Who it suits

Jina AI suits developers and businesses building search applications that use language models, especially those needing embeddings, document reranking, or URL content extraction.
