This page details the experimental Google models that are available for testing in Vertex AI. It also shows you how to test the models by using the Vertex AI Studio and the Vertex AI API. Experimental models don't follow Google's standard model lifecycle plan and versioning scheme, and one model can be swapped for another without prior notice. We also don't guarantee that an experimental model will become a stable model in the future.
Test experimental models
Select one of the following tabs for instructions on how to test experimental Google models.
Console
To test an experimental Google model in Vertex AI Studio, do the following:
In the Google Cloud console, go to Vertex AI Studio.
In the Generate with Gemini section, click Open freeform.
In the Model drop-down, select the model ID of an experimental Google model that you want to test.
For a list of Google experimental model IDs, see Current experimental models on this page.
In the Prompt field, enter your prompt.
Click Submit.
REST
You can send API requests to experimental Google models by specifying its
model ID in the endpoint. For example, to send a request to
gemini-pro-experimental, the endpoint would look like the
following:
https://us-central1-aiplatform.googleapis.com/v1/projects/my-project/locations/us-central1/publishers/google/models/gemini-pro-experimental:streamGenerateContent
For detailed instructions on how to use the API, see Multiturn chat.

Pricing
You aren't billed for the usage of experimental Google models.
Data privacy and feedback
Google does not log your input or output data, and we need your feedback to help improve our experimental models. To provide feedback, fill out the feedback form.
Quota and limitations
Experimental Google models have a quota of 10 queries per minute (QPM). This quota can't be increased.
Experimental Google models don't support the configuration of advanced
parameters or the region, which is set to us-central1.
