Interactive LLM labeling

This example server connects Label Studio to OpenAI
or Azure API to interact with GPT chat models (
gpt-3.5-turbo, gpt-4, etc.).

The interactive flow allows you to perform the following scenarios:

  • Autolabel data given an LLM prompt (e.g. “Classify this text as sarcastic or not”)
  • Collect pairs of user prompts and response inputs to fine tune your own LLM.
  • Automate data collection and summarization over image documents.
  • Create a RLHF (Reinforcement Learning from Human Feedback) loop to improve the LLM’s performance.
  • Evaluate the LLM’s performance.

Check the Generative AI templates section for more examples.

Quickstart

  1. Build and start the Machine Learning backend on http://localhost:9090 

    docker-compose up

  2. Check if it works: 

    $ curl http://localhost:9090/health
{"status":"UP"}

  3. Open a Label Studio project and go to Settings > Model. Connect the model, specifying http://localhost:9090 as the URL.

    Ensure the Interactive preannotations toggle is enabled and click Validate and Save.

  4. The project config should be compatible with the ML backend. This ML backend can support various input data formats
    like plain text, hypertext, images, and structured dialogs. To ensure the project config is compatible, follow these
    rules:

    • The project should contain at least one <TextArea> tag to be used as a prompt input. To specify which <TextArea> tag to use, set the PROMPT_PREFIX environment variable.
      For example, if your labeling config includes <TextArea name="prompt" ...>, then you would specify PROMPT_PREFIX=prompt.
    • The project should contain at least one input data tag from the following list of supported tags: <Text>, <Image>, <HyperText>, <Paragraphs>.
    • If you want to capture the generated LLM response as a label, your labeling config should contain a <Choices> tag.
      For example, <Choices name="choices" ...>.
    • If you want to set the default prompt to be shown before the user input, you can set the DEFAULT_PROMPT environment variable. For example, DEFAULT_PROMPT="Classify this text as sarcastic or not. Text: {text}, Labels: {labels}" or DEFAULT_PROMPT=/path/to/prompt.txt.

    Note that the default prompt isn’t supported with USE_INTERNAL_PROMPT_TEMPLATE=1 mode, so you will need to set USE_INTERNAL_PROMPT_TEMPLATE=0 to use default prompt. You can use the fields from task['data'] in the prompt template, as well as special {labels} field to show the list of available labels.

  5. Open a task and ensure the Auto-Annotation toggle is enabled (it is located at the bottom of the labeling interface).

  6. Enter a prompt in the prompt input field and press Shift+Enter. The LLM response will be generated and displayed in
    the response field.

  7. If you want to apply LLM auto-annotation to multiple tasks at once, go to the Data Manager, select a group of tasks and then select Actions > Retrieve Predictions (or Batch Predictions in Label Studio Enterprise).

Parameters

When deploying the server, you can specify the following parameters as environment variables:

  • DEFAULT_PROMPT: Define a default prompt to be shown before the user input. For example, DEFAULT_PROMPT="Classify this text as sarcastic or not. Text: {text}, Labels: {labels}" or DEFAULT_PROMPT=/path/to/prompt.txt.

    Note that USE_INTERNAL_PROMPT_TEMPLATE should be set to 0 if you are setting a default prompt.

  • PROMPT_PREFIX (default: prompt): An identifier for the prompt input field. For example, if you set
    PROMPT_PREFIX to my-prompt, the following input field will be used for the
    prompt: <TextArea name="my-prompt" ...>.

  • USE_INTERNAL_PROMPT_TEMPLATE (default: 1). If set to 1, the server will use the internal prompt template. If set
    to
    0, the server will use the prompt template provided in the input prompt.

  • PROMPT_TEMPLATE (default: "Source Text: {text}\n\nTask Directive: {prompt}"): The prompt template to use:

    • If USE_INTERNAL_PROMPT_TEMPLATE is set to 1, the server will use
      the default internal prompt template.

    • If USE_INTERNAL_PROMPT_TEMPLATE is set to 0, the server will use the prompt template provided
      in the input prompt (i.e. the user input from <TextArea name="my-prompt" ...>).

    In the later case, the user has to provide the placeholders that match input task fields. For example, if the user wants to use the input_text and instruction field from the input task {"input_text": "user text", "instruction": "user instruction"}, the user has to provide the prompt template like this: "Source Text: {input_text}, Custom instruction : {instruction}".

  • OPENAI_MODEL (default: gpt-3.5-turbo) : The OpenAI model to use.

  • OPENAI_PROVIDER (available options: openai, azure, default - openai) : The OpenAI provider to use.

  • TEMPERATURE (default: 0.7): The temperature to use for the model.

  • NUM_RESPONSES (default: 1): The number of responses to generate in <TextArea> output fields. Useful if you want
    to generate multiple responses and let the user rank the best one.

  • OPENAI_API_KEY: The OpenAI or Azure API key to use. Must be set before deploying the server.

Azure Configuration

If you are using Azure as your OpenAI provider (OPENAI_PROVIDER=azure), you need to specify the following environment
variables:

  • AZURE_RESOURCE_ENDPOINT: This is the endpoint for your Azure resource. It should be set to the appropriate value
    based on your Azure setup.

  • AZURE_DEPLOYMENT_NAME: This is the name of your Azure deployment. It should match the name you’ve given to your
    deployment in Azure.

  • AZURE_API_VERSION: This is the version of the Azure API you are using. The default value is 2023-05-15.
