# BERT-family models specialists for your dedicated team.

BERT and its descendants are encoder transformer models producing contextual representations of text. They are fine-tuned for classification, named entity recognition, similarity and extraction.

## Where BERT-family models fits in a long-term product team.

Encoder models remain the better answer for bounded tasks, and this is consistently underappreciated in the current environment. A fine-tuned BERT classifier runs in milliseconds on a CPU, costs effectively nothing per inference, and frequently beats a large generative model prompted for the same classification.

They need labelled training data, which is the real cost. A few thousand labelled examples is a meaningful investment, which is why teams reach for a prompted language model instead, the right call for low volume and the wrong one once the same classification runs millions of times.

## What your dedicated team does with BERT-family models.

The crossover is usually clear once someone calculates it. At high volume, the labelling cost is recovered quickly against per-token inference spend, and latency improves by an order of magnitude at the same time.

Making that comparison deliberately is part of the engineering judgement companies look for when they [hire AI engineers](https://azendo.co/services/dedicated-ai-engineering-team/).

## Common BERT-family models use cases.

* High-volume classification Millisecond CPU inference where per-token generative cost would dominate.
* Entity extraction at scale Structured fields pulled from documents reliably and cheaply.
* The labelling investment justified Crossover volume calculated, so the decision rests on arithmetic.

## Adding BERT-family models skills to your team.

Model architecture selection is assigned inside AI capacity, with encoder and generative options compared on cost and latency at real volume.
