From Vertex AI Studio, you can complete the following:

Test models using provided prompt samples
Design and manage your prompts
Compare prompt output by model
Evaluate your prompts against select quality metrics
Tune models to get tailored responses
Ground model output to Vertex AI Search or Google Search
Get the Vertex AI API code to implement your work

Test a language model in the prompt gallery

Go to the Prompt Gallery page from the Vertex AI section in the Google Cloud console.
Go to Prompt Gallery
In the Tasks drop-down menu, select Summarization.
Open the Transcript summary card.

The model, parameters, examples, and test prompt are prefilled.
To generate a summary of the prompt, in the Test section, click Submit.

The response is displayed in the Output section.
Optional: To see different results, select a different model from the Model list or change the parameters, and then click Submit.
Optional: To view the Vertex AI API code that you need to generate a transcript summary, click Get code.

Master Vertex AI Studio prompt design and testing

You can create and test your prompts (inputs) for tasks that are relevant to your business use case, and generate responses. By adding inputs and outputs, the LLM is capable of learning in-context from the examples of responses.

You can create a prompt, which gives a precise instruction, and asks the LLM to complete a sentence for you or to answer one-time questions.

Go to the Vertex AI Studio page from the Vertex AI section in the Google Cloud console.
Go to Vertex AI Studio
In the Generate with Gemini section, click Open Freeform.

An untitled prompt opens.
In the prompt box, add a clear and concise description of the task that you want the model to do, such as Suggest a name for a flower shop that sells bouquets of dried flowers.
Click Submit.

A response appears in response box.
Optional: To view different results, adjust the prompt, model, or parameters, and click Submit.
Optional: To view the Vertex AI API code that you need to generate a similar response, click Get code.

Understand Vertex AI Studio prompt categories

From the Vertex AI Studio you can test and customize prompts for different generative AI models.

Freeform: Test text and multimodal prompts using a variety of models. To learn about the models, see Gemini models.
Chat: Try out multi-turn prompts using a variety of language models. To learn about the models, see Gemini models.
Translation: Perform translation.
Vision: Test image model generation using Imagen on Vertex AI.
Speech: Perform text-to-speech and speech-to-text conversions. This is done using the Chirp model. To learn more about Chirp, see Chirp: Universal speech model.

Explore the Gemini prompt gallery in Vertex AI Studio

Prompt samples are available in the Freeform and Chat sections of Vertex AI Studio, and contain a variety of sample prompts that are predesigned to help demonstrate model capabilities. The sample prompts are categorized by the task type, such as summarization, classification, and extraction. Each prompt is preconfigured with specified model and parameter values so you can open the sample prompt and click Submit to get the model to generate a response.

Customize and enhance Gemini prompts

Prompt design is the process of manually creating prompts that elicit the intended response from a language model. By carefully crafting prompts, you can nudge the model to generate a good result for your use case. Prompt design can be an efficient way to experiment with model output.

Vertex AI Studio enables your team to create, save, and collaboratively refine prompts. When designing a new prompt, you can input the prompt text, choose the ideal model, adjust parameters, and test it for immediate feedback. When a prompt is finalized, you can save it within your shared project in Vertex AI Studio.

To get started with prompt design, see Introduction to prompting.

Compare Gemini model output using different prompts

In Vertex AI Studio, you can compare prompt results to see what model and settings pairing works best for your use case.

From the Freeform tab, view your prompts, and select Compare next to the prompts that you want to compare. You can compare up to three prompts side-by-side.

Manage and organize Gemini prompts by using the Saved prompts pages

If you have many prompts, it's necessary to have a central place to manage them. You can view all of your prompts by type under the Saved prompts page. You can version your prompts, restore previous versions, delete, export, and manage prompt naming. You can also add notes to prompts for record keeping and as a way to centrally collaborate with your prompting team.

Go to Saved prompts

Ground your AI prompts with verifiable data in Vertex AI Studio

In generative AI, grounding is the ability to connect language model output to verifiable sources of information. From the Freeform and Chat pages in the Vertex AI Studio, you can choose to ground model output to Vertex AI Search or Google Search. To learn more about grounding, see the Grounding overview. To learn more about grounding model output to Google Search, see Grounding with Google Search.

Discover powerful generative AI models in Model Garden

Model Garden is a platform that helps you discover, test, customize, and deploy Google proprietary and select OSS models and assets. To explore the generative AI models and APIs that are available on Vertex AI, go to Model Garden in the Google Cloud console.

Go to Model Garden

To learn more about Model Garden, including available models and capabilities, see Explore AI models in Model Garden.

Tuning a Gemini model for improved performance

While prompt design is great for quick experimentation, if training data is available, higher quality can be achieved by tuning the model itself. Tuning a model lets you customize the model's response based on examples of the task that you want the model to perform.

To learn how to tune a foundation model, see Tune foundation models.

Use Vertex AI Studio to design, test, and customize your prompts sent to Google's Gemini and PaLM 2 large language models (LLM). After an LLM processes your prompt, it sends you its response. To learn more about the Vertex AI Studio, see Experiment with models in Vertex AI Studio.
