Abstract: This technical report describes the training of nomic-embed-text-v1, the
first fully reproducible, open-source, open-weights, open-data, 8192 context
length English text embedding model that outperforms both OpenAI Ada-002 and
OpenAI text-embedding-3-small on short and long-context tasks. We release the
training code and model weights under an Apache 2 license. In contrast with
other open-source models, we release a training data loader with 235 million
curated text pairs that allows for the full replication of nomic-embed-text-v1.
