Guía de IBM Watsonx.ai: Explorando la IA Generativa y la Ingeniería de Prompts

Tutorial: Understanding Generative AI and Its Applications

Generative AI refers to advanced deep-learning models capable of creating high-quality text, images, and various content based on trained data. Among these, Large Language Models (LLMs) stand out due to their proficiency in general-purpose language understanding and generation.

Using Prompt Engineering to Enhance LLM Responses

The focus of this tutorial is to demonstrate how prompt engineering can be utilized with LLMs to extract accurate, relevant, and context-aware responses. This is particularly aimed at generating comprehensive travel information related to different countries.

Getting Started with watsonx.ai Prompt Lab

Upon launching the watsonx.ai prompt lab and selecting the Freeform mode, you will be greeted with the prompt editor in the center. On the right side, model parameters are displayed for optimization purposes. Additionally, a summary of the number of tokens used during prompt execution is available at the bottom left.

Note: The models accessed through this lab are hosted on IBM Cloud, emphasizing their usability in LLM applications.

Step 1: Initiating Your First Prompt

To kick things off, enter a simple prompt such as:

Model: flan-t5-xxl-11b
Prompt text: I am thinking of traveling to Thailand.

While this may yield a generic output, it sets the stage for more refined prompts.

Step 2: Enhancing Prompt Specificity

To gain more insightful responses, it is essential to be more direct with your queries. Revise the prompt to:

Prompt text: I am thinking of traveling to Thailand. Tell me about Thailand.

Expect a slightly more informative response, yet be ready for incomplete answers due to token limitations.

Step 3: Adjusting Token Limits

Increasing the Max tokens to 200 enables complete sentences in the output:

Max tokens increased to 200

However, the responses might still remain static due to the use of Greedy decoding. Transitioning to Sampling decoding could yield variable outputs.

Step 4: Tailoring Responses

To deliver contextually relevant information, further customize your prompt:

Prompt text: I am thinking of traveling to Thailand. I like water sports and food. Tell me about Thailand.

Although this offers more detail, lack of specificity might still hinder quality output.

Step 5: Exploring Different Models

The watsonx.ai prompt lab provides access to various models optimized for distinct tasks. By selecting options like llama-2-70b-chat, you can assess its relevance for dialogue purposes:

Select model: llama-2-70b-chat

Utilizing this model might enhance the depth and clarity of the responses.

Step 6: Defining Response Limits

Refining the prompt by imposing a limit can prevent token overflow while guaranteeing valuable output:

New prompt: I am thinking of traveling to Thailand. I like water sports and food. Give me 5 sentences on Thailand.

This approach promises targeted and concise information.

Conclusion: Continuous Learning and Application

Generating quality outputs with LLMs often requires iterative refinement in both model selection and prompt structure. Experimentation with context, examples, and limitations is critical for achieving desired results.

For developers, detailed insights into model usage and API interactions are accessible via the View code feature in the prompt lab, providing transparency and control over the application process.

By employing these practices, users can fully exploit the potential of generative AI in delivering insightful applications.
