Google VertexAI Generate
Overview
You can use this Snap to generate text responses using the Gemini VertexAI model and model parameters.

Transform-type Snap
Works in Ultra Tasks
Prerequisites
Supported models:
- text-embedding-005
- text-multilingual-embedding-002
- text-embedding-large-exp-03-07
You need to have one of the following accounts configured for your Google VertexAI Snaps:
Limitations
- gemini-1.0-pro and gemini-1.5-pro is not supported for the Top K field.
- models/gemini-1.5-flash is not supported for the JSON mode field.
- Attention: In September 24, Google is deprecating the
googleSearchRetrieval
field with the gemini-1.5-flash and gemini-1.5-pro. Thifunctionality
Snap views
View | Description | Examples of upstream and downstream Snaps |
---|---|---|
Input | This Snap supports a maximum of one binary or document input view. When the input type is a document, you must provide a field to specify the path to the input prompt. The Snap requires a prompt, which can be generated either by the Google GenAI Prompt Generator or any user-desired prompt intended for submission to the Gemini API. | |
Output | This Snap has at the most one document output view. The Snap provides the result generated by the Gemini API. | Mapper |
Error |
Error handling is a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that the Snap might encounter when running the pipeline by choosing one of the following options from the When errors occur list under the Views tab. The available options are:

Snap settings
- Expression icon (
): Allows using JavaScript syntax to access SnapLogic Expressions to set field values dynamically (if enabled). If disabled, you can provide a static value. Learn more.
- SnapGPT (
): Generates SnapLogic Expressions based on natural language using SnapGPT. Learn more.
- Suggestion icon (
): Populates a list of values dynamically based on your Snap configuration. You can select only one attribute at a time using the icon. Type into the field if it supports a comma-separated list of values.
- Upload
: Uploads files. Learn more.
Field / Field set | Type | Description |
---|---|---|
Label | String |
Required. Specify a unique name for the Snap. Modify this to be more appropriate, especially if more than one of the same Snaps is in the pipeline. Default value: ... Example: ... |
Model name | String/Expression/ Suggestion |
Required. The identifier for the Gemini text generation models. Supported models:
Important: Some models (suchas gemini-1.5-flash and gemini-1.5-pro) are planned to be deprecated by the vendor.
Default value: N/A Example: |
Model location | String/Expression/ Suggestion |
The location of the model. Default value: N/A Example: us-central1 |
Use content payload | Checkbox |
Select this checkbox to generate responses using the contents specified in the Content payload field. Default status: Deselected |
Prompt | String/Expression |
Required. The prompt to run against the model. Default value: N/A Example: "Hello" |
Content payload | String/Expression |
Required. Specify the content payload to send to the Gemini text generation endpoint for all contents. Contents coming from the Prompt Generator Snap will be correctly formatted. Default value: N/A Example:Content payload:
Tool payload:
Allowed function names:
|
Model parameters |
Parameters used to tune the model runtime. |
|
Top K | Integer/Expression |
The number of high-probability tokens considered for each generation step, controlling the randomness of the output. If left blank, the endpoint uses its default value. Default value: N/A Example: |
Stop sequences | String/Expression |
Sequence of tokens to stop the completion at. Default value: N/A Example:
|
Temperature | Decimal/Expression |
The sampling temperature to use, a decimal value between 0 and 1. If left blank, the endpoint uses its default value. Default value: N/A Example: 0.2 |
Maximum tokens | Integer/Expression |
Maximum number of tokens that can be generated in the Gemini text generation foundation model. If left blank, the endpoint uses its default value. Default value: N/A Example: 50 |
Top P | Decimal/Expression |
The nucleus sampling value, which must be a decimal between 0 and 1. If left blank, the endpoint uses its default value. Default value: N/A Example: 0.2 |
Advanced prompt configurations |
Configure the advanced prompt settings. |
|
System prompt | String/Expression |
Specify the persona for the model to adopt in the responses. This initial instruction guides the LLM's responses and actions. Default value: N/A Example:
|
JSON mode | Checkbox/Expression |
Select this checkbox to include a JSON output from the Gemini API. Default status: Deselected |
Built-in tools configurations |
Configure built-in tool behavior and inputs. |
|
Tool type | Dropdown list | The type of tool to invoke from the built-in toolset.
Default value: N/A Example: ... |
Top K | Integer/Expression | Maximum number of documents to retrieve based on relevance. Displays when vertexRagStore is selected. Default value: N/A Example: 20 |
RAG corpus | String/Expression/ Suggestion | Corpus used in Vertex RAG store for document retrieval. Displays when vertexRagStore is selected. Default value: N/A Example: 3379951520340000000:p0_rag_test |
Google retrieval mode | Dropdown list | Select the Google search mode to use.
Default value: N/A Example: MODE_UNSPECIFIED |

Ranking configurations | object | Configuration for ranking retrieved results. Default value: N/A Example: |
RAG corpus location | String/Expression/ Suggestion | The location of the RAG corpus. Default value: N/A Example: us-central1 |
Filter configurations | object | Configuration for corpus-level document filtering.
Default value: N/A Example:
|
Advanced response configurations |
Modify the response settings to customize the responses and optimize output processing. |
|
Structured outputs | Checkbox/Expression |
Ensures the model always returns outputs that match your defined JSON Schema. Default value: N/A Example:
|
Simplify response | Checkbox/Expression |
Select this checkbox to receive a simplified response format that retains only the most commonly used fields and standardizes the output for compatibility with other models. Default status: Deselected |
Continuation requests | Checkbox/Expression |
Select this checkbox to enable continuation requests. If selected, the Snap will automatically request additional responses if the finish reason is maximum tokens. Default status: Deselected |
Continuation requests limit | Integer/Expression | Required. The maximum number of continuation requests to be made. Default value: N/A Example: 3 |
Debug mode | Checkbox/Expression |

Additional information
The following table lists the Models and their corresponding minimum, maximum, and default values for the Temperature field:
Model name | Default value | Minimum value | Maximum value |
---|---|---|---|
gemini-1.5-pro | 1.0 | 0.0 | 2.0 |
gemini-1.0-pro-vision | 0.4 | 0.0 | 1.0 |

Troubleshooting
Continuation requests limit error.
The Continuation requests limit value is invalid.
Provide a valid value for Continuation requests limit that is between 1-20.
