Embeddings API

The quiet engine behind search that works.

Embeddings turn text into vectors that capture meaning, which is what makes semantic search, retrieval for AI and smart classification possible. It is unglamorous infrastructure that decides whether your AI answers from the right documents. We build embedding pipelines that stay accurate and stay fresh.

In plain terms

Keyword search finds words. Embeddings find meaning.

Ask for “leave policy” and get the document titled “absence entitlements”. Here is what changes.

Without it

  • Search that misses documents phrased differently
  • AI assistants guessing because retrieval failed
  • Duplicates and stale files polluting every answer
  • Classification rules maintained by hand

With it

  • Search that matches meaning, not just words
  • AI grounded in the passages that actually answer the question
  • An index that refreshes as content changes
  • Routing, deduplication and recommendations that run themselves

Questions we hear a lot

Common questions about the Embeddings API

What are embeddings, in plain terms?

A way of turning text into numbers that capture meaning, so a computer can tell that two differently worded passages are about the same thing. Everything useful, from semantic search to AI grounding, builds on that.

What does it cost?

Very little per document. Embedding models are among the cheapest in the API, priced per million tokens, and the real cost is in doing the pipeline properly, once.

Is our content used to train models?

No. API business data is not used for training by default.

Do we need a vector database?

It depends on scale. Options run from managed vector stores to capabilities inside platforms you already own. We recommend the simplest thing that meets your volume and latency, not the trendiest.

What is semantic search?

Search that matches meaning rather than exact words, so a search for staff leave policy also finds a document titled annual holiday entitlements. Embeddings are what make that possible, and it is why AI answers from the right document instead of the one that happened to share a keyword.

Why do AI answers cite the wrong document?

Nearly always because the retrieval step picked the wrong source, not because the model is weak. Fixing the embeddings and how content is chunked usually improves answer quality far more than changing model.

How often does this need refreshing?

Whenever the underlying content changes. Stale embeddings are one of the quieter failure modes: the AI keeps answering confidently from a policy you replaced six months ago. We build the refresh into the pipeline rather than leaving it manual.

Can this run on our own infrastructure?

Yes, if data sovereignty requires it. There is a trade-off in quality and effort, and we will set that out plainly rather than assuming either answer.
