Pixeltable’s Gemini integration supports two authentication methods:
* Google AI Studio: requires an API key from
[https://aistudio.google.com/app/apikey](https://aistudio.google.com/app/apikey)
* Vertex AI: uses Application Default Credentials via the Google Cloud
SDK
### Prerequisites
For Google AI Studio:
* A Google AI Studio account with an API key
([https://aistudio.google.com/app/apikey](https://aistudio.google.com/app/apikey))
For Vertex AI:
* A Google Cloud project with the Vertex AI API enabled
* The Google Cloud SDK installed and configured
(`gcloud auth application-default login`)
### Important notes
* Usage may incur costs based on your plan.
* Be mindful of sensitive data and consider security measures when
integrating with external services.
```python theme={null}
%pip install -qU pixeltable google-genai
```
```python theme={null}
import os
vertex_enabled = (
os.environ.get('GOOGLE_GENAI_USE_VERTEXAI', '').lower() == 'true'
)
# Option 1: Google AI Studio (API key)
# Set GEMINI_API_KEY or GOOGLE_API_KEY in your environment,
# or add api_key to the [gemini] section of $PIXELTABLE_HOME/config.toml
if (
not vertex_enabled
and 'GEMINI_API_KEY' not in os.environ
and 'GOOGLE_API_KEY' not in os.environ
):
import getpass
os.environ['GEMINI_API_KEY'] = getpass.getpass(
'Google AI Studio API Key:'
)
# Option 2: Vertex AI (Application Default Credentials)
# Uncomment and set the following environment variables to use Vertex AI instead:
# os.environ['GOOGLE_GENAI_USE_VERTEXAI'] = 'true'
# os.environ['GOOGLE_CLOUD_PROJECT'] = 'your-project-id'
# os.environ['GOOGLE_CLOUD_LOCATION'] = 'us-central1' # optional, defaults to us-central1
# Then authenticate via: gcloud auth application-default login
```
Now let’s create a Pixeltable directory to hold the tables for our demo.
```python theme={null}
import pixeltable as pxt
# Remove the 'gemini_demo' directory and its contents, if it exists
pxt.drop_dir('gemini_demo', force=True)
pxt.create_dir('gemini_demo')
```
Connected to Pixeltable database at: postgresql+psycopg://postgres:@/pixeltable?host=/Users/asiegel/.pixeltable/pgdata
Created directory 'gemini\_demo'.
\
## Generate content
Create a Table: In Pixeltable, create a table with columns to represent
your input data and the columns where you want to store the results from
Gemini.
```python theme={null}
from google.genai.types import GenerateContentConfigDict
from pixeltable.functions import gemini
# Create a table in Pixeltable and pick a model hosted on Google AI Studio with some parameters
t = pxt.create_table('gemini_demo/text', {'input': pxt.String})
config = GenerateContentConfigDict(
max_output_tokens=300, temperature=1.0, top_p=0.95, top_k=40
)
t.add_computed_column(
output=gemini.generate_content(
t.input, model='gemini-2.5-flash', config=config
)
)
```
Created table 'text'.
Added 0 column values with 0 errors in 0.01 s
No rows affected.
```python theme={null}
# Ask Gemini to generate some content based on the input
t.insert(
[
{'input': 'Write a story about a magic backpack.'},
{'input': 'Tell me a science joke.'},
]
)
```
Inserted 2 rows with 0 errors in 4.96 s (0.40 rows/s)
2 rows inserted.
```python theme={null}
# Parse the response into a new column
t.add_computed_column(
response=t.output['candidates'][0]['content']['parts'][0]['text']
)
t.select(t.input, t.response).head()
```
## Generate images with Imagen
```python theme={null}
from google.genai.types import GenerateImagesConfigDict
from pixeltable.functions import gemini
images_t = pxt.create_table('gemini_demo/images', {'prompt': pxt.String})
config = GenerateImagesConfigDict(aspect_ratio='16:9')
images_t.add_computed_column(
generated_image=gemini.generate_images(
images_t.prompt, model='imagen-4.0-generate-001', config=config
)
)
```
Created table 'images'.
Added 0 column values with 0 errors in 0.02 s
No rows affected.
```python theme={null}
images_t.insert(
[{'prompt': 'A friendly dinosaur playing tennis in a cornfield'}]
)
```
Inserted 1 row with 0 errors in 12.31 s (0.08 rows/s)
1 row inserted.
Created table 'videos'.
Added 0 column values with 0 errors in 0.01 s
No rows affected.
```python theme={null}
videos_t.insert(
[
{
'prompt': 'A giant pixel floating over the open ocean in a sea of data'
}
]
)
```
Inserted 1 row with 0 errors in 40.06 s (0.02 rows/s)
1 row inserted.
```python theme={null}
videos_t.head()
```
## Generate Video from an existing Image
We’ll add an additional computed column to our existing `images_t` to
animate the generated images.
```python theme={null}
images_t.add_computed_column(
generated_video=gemini.generate_videos(
image=images_t.generated_image, model='veo-2.0-generate-001'
)
)
```
Added 1 column value with 0 errors in 52.22 s (0.02 rows/s)
1 row updated.
```python theme={null}
images_t.head()
```
