How much does embedding cost?

OpenAI's text-embedding-3-small costs $0.02 per 1M tokens. A typical 1,000-word document uses about 1,300 tokens, costing roughly $0.000026 to embed. Even 10,000 documents cost under $1.

How often do I need to re-embed?

Only when content changes. If you update a document, only that document needs re-embedding. Initial embedding is a one-time cost per document version.
