About this API

Cohere is a Canadian LLM company founded 2019 by Aidan Gomez (one of the "Attention Is All You Need" paper authors). Unlike OpenAI/Anthropic, Cohere doesn't target consumer market (no ChatGPT-like product), focusing on enterprise RAG and data privacy. Strongest in Embeddings + Rerank combo: Embed-v3 is one of the top multilingual embedding models (high-quality for Chinese, Japanese, French); Rerank service reorders top-100 first-stage search results into more relevant top-10 (essential for many production RAG apps). Command R+ is its chat model, RAG-trained (understands retrieved context better than general LLMs). Customers mostly in finance, healthcare, government — privacy-sensitive industries; Cohere supports VPC deployment and on-prem.

FAQ

Cohere vs. OpenAI embeddings?+

Cohere Embed-v3 is stronger multilingual (OpenAI text-embedding-3 primarily English-trained). For Chinese RAG, try Cohere.

What is Rerank?+

Two-stage retrieval: first step uses embedding to fetch top-100 candidates; Rerank re-scores to pick truly most relevant top-10. Significantly lifts RAG quality.
