Step 3. Configure and publish the processes

Configure the deployment details of the LLM model and publish the processes.

To publish the

Get Content from File

process, click Actions
in the row that contains the process and select Publish
.

Open the

Chat with File

process.

On the

Temp Fields

tab of the Start step, in the

Model_id

field, enter the deployment ID of the LLM model that was deployed.

The default model id is

anthropic.claude-3-sonnet-20240229-v1:0

. You can optionally edit the model id.

Optionally, in the

Configure Request Parameters

step, enter the prompt instructions in the

Assignments

field by updating the

Prompt_Configuration

field using the Expression Editor, as shown in the following sample code:

For Prompt_Configuration: 
<GenerationConfig_AwsBedrock_PO-1>
   <Temperature>0.5</Temperature>
   <TopP>0.6</TopP>
   <MaxTokens>500</MaxTokens>
</GenerationConfig_AwsBedrock_PO-1>

For the

Prompt_Configuration

field, enter values for the following properties:

Property	Description
temperature	Controls the randomness of the model's output. A lower value close to 0 makes the output more deterministic, while a higher value close to 1 increases randomness and creativity. For example, if temperature is set to 0.5, the model balances between deterministic and creative outputs.
topP	Determines the cumulative probability threshold for token selection. The model considers the smallest set of tokens whose cumulative probability meets or exceeds topP . For example, if topP is set to 0.1, the model considers only the top 10% most probable tokens at each step.
max_tokens	Defines the token count of your prompt. The value can't exceed the model's context length. Most of the models have a context length of 2048 tokens.

Optionally, in the

Prepare Request

step, enter the prompt instructions in the

Assignments

field by updating the

Request

field using the Expression Editor, as shown in the following sample code:

For Request:
<root xmlns:m="urn:informatica:ae:xquery:json2xml:meta-data">
<system m:isArray="true">
<type>text</type>
<text>You are an helpfull assistant .{$temp.Content_From_File }</text>
</system>
<messages m:isArray="true">
<role>user</role>
<content m:isArray="true">
<type>text</type>
<text>{$input.User_Prompt }</text>
</content>
</messages>
<interfenceConfig>
<max_tokens m:type="xs:int">{$temp.Prompt_Configuration[1]/MaxTokens }</max_tokens>
<temperature m:type="xs:double">{$temp.Prompt_Configuration[1]/Temperature }</temperature>
<topP m:type="xs:double">{$temp.Prompt_Configuration[1]/TopP }</topP>
</interfenceConfig>
</root>

Save and publish the process.
