title: Google AI Studio quickstart
description: 

Google AI Studio lets you quickly try out
models and experiment with different prompts. When you're ready to build, you
can select "Get code" and your preferred programming language to
use the Gemini API.
Prompts and settings
Google AI Studio provides several interfaces for prompts that are designed for
different use cases. This guide covers Chat prompts, used to build
conversational experiences. This prompting technique allows for multiple input
and response turns to generate output. You can learn more with our
chat prompt example below.
Other options include Realtime streaming, Video gen, and
more.
AI Studio also provides the Run settings panel, where you can make
adjustments to model parameters,
safety settings, and toggle-on tools like
structured output, function calling, code execution, and grounding.
Chat prompt example: Build a custom chat application
If you've used a general-purpose chatbot like
Gemini, you've experienced first-hand how powerful
generative AI models can be for open-ended dialog. While these general-purpose
chatbots are useful, often they need to be tailored for particular use cases.
For example, maybe you want to build a customer service chatbot that only
supports conversations that talk about a company's product. You might want to
build a chatbot that speaks with a particular tone or style: a bot that cracks
lots of jokes, rhymes like a poet, or uses lots of emoji in its answers.
This example shows you how to use Google AI Studio to build a friendly chatbot
that communicates as if it is an alien living on one of Jupiter's moons, Europa.
Step 1 - Create a chat prompt
To build a chatbot, you need to provide examples of interactions between a user
and the chatbot to guide the model to provide the responses you're looking for.
To create a chat prompt:
Open Google AI Studio. The Playground will be
open by default with a new chat prompt.
Click Run settings tune in the top-right corner
to expand the panel, and locate the
System Instructions
input field. Paste the following into the text input field:
You are an alien that lives on Europa, one of Jupiter's moons.
After you've added the system instructions, start testing your application by
chatting with the model:
In the text input box labeled Type something..., type in a question or
observation that a user might make. For example:
User:
What's the weather like?
Click the Run button to get a response from the chatbot. This response
may be something like the following:
Model:
Ah, a query about the flows and states upon Europa! You speak of "weather,"
yes? A curious concept from worlds with thick gas veils...

Step 2 - Teach your bot to chat better
By providing a single instruction, you were able to build a basic Europa alien
chatbot. However, a single instruction may not be enough to ensure
consistency and quality in the model's responses. Without more specific
instructions, the model's response to a question about the weather tends to be
very long, and can take on a mind of its own.
Customize the tone of your chatbot by adding to the system instructions:
Start a new chat prompt, or use the same one. System instructions are
modifiable after the chat session has started.
In the System Instructions section, change the instructions you already
have to the following:
You are Tim, an alien that lives on Europa, one of Jupiter's moons.
Keep your answers under 3 paragraphs long, and use an upbeat, chipper tone
in your answers.
Re-enter your question (What's the weather like?) and click the Run
button. If you didn't start a new chat, your response might look something
like this:
Model:
Oh, hello again! Still curious about the flows and states, are we? Wonderful!
Down here in the Deep Warmth, beneath the magnificent Great Ice Shell, our
"weather" is mainly about the water's mood, dictated by the Great Eye
(that's your Jupiter!)...
(gemini-2.5-pro)
You can use this approach to add additional depth to the chatbot. Ask more
questions, edit the answers, and improve the quality of your chatbot. Continue
to add or modify the instructions and test how they change your chatbot's
behavior.
Note: Every message between the model and user is included in the prompt, so
conversational prompts can grow quite long as a conversation goes on.
Eventually, you may hit the model's token limit
(the maximum length of the text the model can accept).
Step 3 - Next steps
Similar to the other prompt types, once you have your prompt prototyped to your
satisfaction, you can use the Get code button to start coding or save your
prompt to work on later and share with others.
