> An unmodified, checksum-verified copy of the files [Dakera](https://dakera.ai) uses from [nomic-ai/modernbert-embed-base](https://huggingface.co/nomic-ai/modernbert-embed-base). The model is by **Nomic AI**; all credit goes to its authors.

## In Dakera

A ModernBERT embedding model with a long context: `DAKERA_MODEL=modernbert-embed-base`.

Dakera fetches this embedding model from this repository first and from the original repositories if it is unreachable, so installs never depend on a single source. Both are checked against the same SHA-256, and the [Dakera Docker image](https://github.com/Dakera-AI/dakera-deploy) ships the default models ready to run, with no download at startup.

Apache-2.0, the same as the original model (see [`LICENSE`](https://huggingface.co/DakeraAI/modernbert-embed-base/blob/main/LICENSE)). For what the model does, how it was trained and how to cite it, see the [original model card](https://huggingface.co/nomic-ai/modernbert-embed-base).

## About Dakera

**[Dakera](https://dakera.ai) is a self-hosted memory engine for AI agents.** It gives agents long-term memory that survives sessions: hybrid vector and full-text retrieval, reranking, entity extraction and importance decay, in a single Rust binary that runs on your own servers, with an MCP server for Claude, Cursor and other agents.

```bash
docker run -p 3000:3000 -e DAKERA_ROOT_API_KEY=dk-mykey ghcr.io/dakera-ai/dakera:latest
