# nomic-embed-text-v1.5: Resizable Production Embeddings with Matryoshka Representation Learning
|
2611 |
|
2612 |
-
`nomic-embed-text-v1.5` is an improvement upon [Nomic Embed](https://huggingface.co/nomic-ai/nomic-embed-text-v1) that utilizes [Matryoshka Representation Learning](https://arxiv.org/abs/2205.13147) which gives developers the flexibility to trade off the embedding size for a negligible reduction in performance.

|
2633 |
-
The easiest way to get started with Nomic Embed is through the Nomic Embedding API.
|
2634 |
-
|
2635 |
-
Generating embeddings with the `nomic` Python client is as easy as
|
2636 |
-
|
2637 |
-
```python
|
2638 |
-
from nomic import embed

## Training Details
|
2659 |
-
|
2660 |
-
We train our embedder using a multi-stage training pipeline. Starting from a long-context [BERT model](https://huggingface.co/nomic-ai/nomic-bert-2048),
|
2661 |
-
the first unsupervised contrastive stage trains on a dataset generated from weakly related text pairs, such as question-answer pairs from forums like StackExchange and Quora, title-body pairs from Amazon reviews, and summarizations from news articles.
|
2662 |
-
|
2663 |
-
In the second finetuning stage, higher quality labeled datasets such as search queries and answers from web searches are leveraged. Data curation and hard-example mining is crucial in this stage.
|
2664 |
-
|
2665 |
-
For more details, see the Nomic Embed [Technical Report](https://static.nomic.ai/reports/2024_Nomic_Embed_Text_Technical_Report.pdf) and corresponding [blog post](https://blog.nomic.ai/posts/nomic-embed-matryoshka).
