# What's new in Azure OpenAI Service

## March 2024

### 2024-03-01-preview API released
22
+
23
+
`2024-03-01-preview` has all the same functionality as `2024-02-15-preview` and adds two new parameters for embeddings:
24
+
25
+
-`encoding_format` allows you to specify the format to generate embeddings in `float`, or `base64`. The default is `float`.
26
+
-`dimensions` allows you set the number of output embeddings. This parameter is only supported with the new third generation embeddings models: `text-embedding-3-large`, `text-embedding-3-small`. Typically larger embeddings are more expensive from a compute, memory, and storage perspective. Being able to adjust the number of dimensions allows more control over overall cost and performance. The `dimensions` parameter is not supported in all versions of the OpenAI 1.x Python library, to take advantage of this parameter we recommend upgrading to the latest version: `pip install openai --upgrade`.
27
+
28
+
If you are currently using a preview API version to take advantage of the latest features, we recommend consulting the [API version lifecycle](./api-version-deprecation.md) article to track how long your current API version will be supported.
