# Naderu — specialised models by BytesBrains

**We train foundation models into specialised ones, release them with evidence, and sell the engineering around them.**

Naderu is a venture of **BytesBrains Pte. Ltd.** — [naderu.com](https://naderu.com).

## How we release

- **No model without evaluation.** A model is published here only after it passes its evaluation gate, and its card cites the exact eval suite version.
- **Provenance stated plainly.** Every model names the upstream foundation model it was built from, and the terms that come with it.
- **Reproducible.** Reported numbers come from a versioned training recipe and a versioned eval suite.
