    This component is currently in the incubation phase. Although it is available for use, it is under active development and may be subject to changes. We welcome feedback and encourage users to explore its capabilities.

    Short description

    The OpenAIClient component lets you compose and send queries to OpenAI’s GPT language models and processes the responses.

    You can define control logic which either refines your query based on GPT’s response, or moves to the next record. This is great in situations when you’re not happy with GPT’s response and want to continue "chatting about the same input record", until you’re satistifed with the results.

    Warning Make sure the queries you generate and send to OpenAI only contain data you are willing to share with their service. Make sure you conform to your data security, privacy and governance standards.

    OpenAIClient attributes

    Attribute Req Description Possible values

    Basic

    API key

    yes

    The key used to authenticate requests to OpenAI’s API. You can get it from your OpenAI dashboard at https://platform.openai.com.

    Model

    no

    The OpenAI model ID to use. Supported models are available at https://platform.openai.com/docs/models.

    gpt-4o-mini (default)

    System message URL

    no

    An URL or relative path to a .txt file containing a system message. Used to load longer system prompts from external files.

    System message

    no

    A instruction message that is sent to the GPT model as context. Can help shape the tone or style of the response.

    Query and response processor

    yes

    CTL transformation script to fully control the GPT interaction workflow (input → query → response → output). See CTL interface.

    Output field

    yes

    The name of the field in the output record where the GPT response will be stored.

    Temperature

    no

    Controls the creativity or randomness of the model’s output. Lower values make the output more deterministic, higher values more random. Range: 0.0–2.0

    CTL interface

    OpenAIClient requires a CTL transformation (named Query and response processor).

    Its function newChat() is called once for each input record. Consequently, the functions prepareQuery() and processResponse() are called repeatedly for each input record until assistant response is either accepted or skipped, or the processing is stopped.

    CTL Template Functions

    boolean newChat()

    Required

    Yes

    Description

    Prepares the component for a new input record. The return value signifies whether the chat history (messages for previous input records) shall be preserved or reset; reset clears the history but keeps the component-level system message.

    Invocation

    Called once for each input record.

    Returns

    true – reset the chat context | false – preserve it

    string prepareQuery(list[list[string]] chatContext, integer iterationIndex)

    Required

    Yes

    Description

    Prepare a new query. The returned string will be added to the chat context as user message; if null is returned, the method shall modify the context on its own.

    Invocation

    Called repeatedly for each input record, after newChat() and before processResponse().

    Input Parameters

    list[list[string]] chatContext – modifiable chat context, a list of previous messages

    integer iterationIndex – number of calls of this method for the current input record (0 for the first call)

    Returns

    string – a new user message, or null if none shall be added

    Example

    		 
    function string prepareQuery(
        list[list[string]] chatContext,
        integer iterationIndex) {
    if (iterationIndex == 0) {
        return $in.0.message;
    } else {
        return "Try it once more.";
    }
}

    integer processResponse(list[list[string]] chatContext, integer iterationIndex, string assistantResponse)

    Required

    Yes

    Description

    Process assistant response: write it to output, repeat a query with additional instructions, or ignore it.

    Invocation

    Called repeatedly for each input record when assistant response is received, as long as it returns CONTINUE.

    Input Parameters

    list[list[string]] chatContext – modifiable chat context, including the current assistant response (in the last position)

    integer iterationIndex – number of calls of this method for the current input record (0 for the first call)

    string assistantResponse – the current assistant response, just for convenience

    Returns

    integer – a code indicating whether an output record shall be generated:

    • OK – An output record is generated and next input record is processed.

    • CONTINUE – No output is generated, prepareQuery() is called again with increased iteration index.

    • SKIP – The response is ignored and next input record is processed.

    • STOP – Processing (of all records) is stopped, an exception is thrown.

    Example

    		 
    function integer processResponse(
        list[list[string]] chatContext,
        integer iterationIndex,
        string assistantResponse) {
    try {
        $out.0.response = parseJson(assistantResponse);
        return OK;
    } catch (CTLException e) {
        if (iterationIndex < 3) {
            push(chatContext, ["USER", "Answer with a valid JSON."]);
            return CONTINUE;
        } else {
            return SKIP;
        }
    }
}
