Advanced Usage

The gollm package offers a range of advanced features to enhance your AI applications:

Prompt Engineering

Create sophisticated prompts with multiple components:

prompt := gollm.NewPrompt("Explain the concept of recursion in programming.",
    gollm.WithContext("The audience is beginner programmers."),
    gollm.WithDirectives(
        "Use simple language and avoid jargon.",
        "Provide a practical example.",

    ),
    gollm.WithOutput("Structure your response with sections: Definition, Example, Pitfalls, Best Practices."),
    gollm.WithMaxLength(300),
)

response, err := llm.Generate(ctx, prompt)
if err != nil {
    log.Fatalf("Failed to generate explanation: %v", err)
}

fmt.Printf("Explanation of Recursion:\n%s\n", response)

Pre-built Functions (Chain of Thought)

Use the ChainOfThought function for step-by-step reasoning:

question := "What is the result of 15 * 7 + 22?"
response, err := tools.ChainOfThought(ctx, llm, question)
if err != nil {
    log.Fatalf("Failed to perform chain of thought: %v", err)
}
fmt.Printf("Chain of Thought:\n%s\n", response)

Working with Examples

Load examples directly from files:

examples, err := utils.ReadExamplesFromFile("examples.txt")
if err != nil {
    log.Fatalf("Failed to read examples: %v", err)
}

prompt := gollm.NewPrompt("Generate a similar example:",
    gollm.WithExamples(examples...),
)

response, err := llm.Generate(ctx, prompt)
if err != nil {
    log.Fatalf("Failed to generate example: %v", err)
}
fmt.Printf("Generated Example:\n%s\n", response)

Prompt Templates

Create reusable prompt templates for consistent prompt generation:

// Create a new prompt template
template := gollm.NewPromptTemplate(
    "AnalysisTemplate",
    "A template for analyzing topics",
    "Provide a comprehensive analysis of {{.Topic}}. Consider the following aspects:\n" +
    "1. Historical context\n" +
    "2. Current relevance\n" +
    "3. Future implications",
    gollm.WithPromptOptions(
        gollm.WithDirectives(
            "Use clear and concise language",
            "Provide specific examples where appropriate",
        ),
        gollm.WithOutput("Structure your analysis with clear headings for each aspect."),
    ),
)

// Use the template to create a prompt
data := map[string]interface{}{
    "Topic": "artificial intelligence in healthcare",
}
prompt, err := template.Execute(data)
if err != nil {
    log.Fatalf("Failed to execute template: %v", err)
}

// Generate a response using the created prompt
response, err := llm.Generate(ctx, prompt)
if err != nil {
    log.Fatalf("Failed to generate response: %v", err)
}

fmt.Printf("Analysis:\n%s\n", response)

Structured Output (JSON Output Validation)

Ensure your LLM outputs are in a valid JSON format:

prompt := gollm.NewPrompt("Analyze the pros and cons of remote work.",
    gollm.WithOutput("Respond in JSON format with 'topic', 'pros', 'cons', and 'conclusion' fields."),
)

response, err := llm.Generate(ctx, prompt, gollm.WithJSONSchemaValidation())
if err != nil {
    log.Fatalf("Failed to generate valid analysis: %v", err)
}

var result AnalysisResult
if err := json.Unmarshal([]byte(response), &result); err != nil {
    log.Fatalf("Failed to parse response: %v", err)
}

fmt.Printf("Analysis: %+v\n", result)

Prompt Optimizer

Use the PromptOptimizer to automatically refine and improve your prompts:

initialPrompt := gollm.NewPrompt("Write a short story about a robot learning to love.")
taskDescription := "Generate a compelling short story that explores the theme of artificial intelligence developing emotions."

optimizerInstance := optimizer.NewPromptOptimizer(
    llm,
    initialPrompt,
    taskDescription,
    optimizer.WithCustomMetrics(
        optimizer.Metric{Name: "Creativity", Description: "How original and imaginative the story is"},
        optimizer.Metric{Name: "Emotional Impact", Description: "How well the story evokes feelings in the reader"},
    ),
    optimizer.WithRatingSystem("numerical"),
    optimizer.WithThreshold(0.8),
    optimizer.WithVerbose(),
)

optimizedPrompt, err := optimizerInstance.OptimizePrompt(ctx)
if err != nil {
    log.Fatalf("Optimization failed: %v", err)
}

fmt.Printf("Optimized Prompt: %s\n", optimizedPrompt.Input)

Model Comparison

Compare responses from different LLM providers or models:

configs := []*gollm.Config{
    {
        Provider:  "openai",
        Model:     "gpt-4o-mini",
        APIKey:    os.Getenv("OPENAI_API_KEY"),
        MaxTokens: 500,
    },
    {
        Provider:  "anthropic",
        Model:     "claude-3-5-sonnet-20240620",
        APIKey:    os.Getenv("ANTHROPIC_API_KEY"),
        MaxTokens: 500,
    },
    {
        Provider:  "groq",
        Model:     "llama-3.1-70b-versatile",
        APIKey:    os.Getenv("GROQ_API_KEY"),
        MaxTokens: 500,
    },
}

promptText := "Tell me a joke about programming. Respond in JSON format with 'setup' and 'punchline' fields."

validateJoke := func(joke map[string]interface{}) error {
    if joke["setup"] == "" || joke["punchline"] == "" {
        return fmt.Errorf("joke must have both a setup and a punchline")
    }
    return nil
}

results, err := tools.CompareModels(context.Background(), promptText, validateJoke, configs...)
if err != nil {
    log.Fatalf("Error comparing models: %v", err)
}

fmt.Println(tools.AnalyzeComparisonResults(results))

Memory Retention

Enable memory to maintain context across multiple interactions:

llm, err := gollm.NewLLM(
    gollm.SetProvider("openai"),
    gollm.SetModel("gpt-3.5-turbo"),
    gollm.SetAPIKey(os.Getenv("OPENAI_API_KEY")),
    gollm.SetMemory(4096), // Enable memory with a 4096 token limit
)
if err != nil {
    log.Fatalf("Failed to create LLM: %v", err)
}

ctx := context.Background()

// First interaction
prompt1 := gollm.NewPrompt("What's the capital of France?")
response1, err := llm.Generate(ctx, prompt1)
if err != nil {
    log.Fatalf("Failed to generate response: %v", err)
}
fmt.Printf("Response 1: %s\n", response1)

// Second interaction, referencing the first
prompt2 := gollm.NewPrompt("What's the population of that city?")
response2, err := llm.Generate(ctx, prompt2)
if err != nil {
    log.Fatalf("Failed to generate response: %v", err)
}
fmt.Printf("Response 2: %s\n", response2)

Best Practices

1. Prompt Engineering:

   • Use NewPrompt() with options like WithContext(), WithDirectives(), and WithOutput() to create well-structured prompts.
   • Example:

     prompt := gollm.NewPrompt("Your main prompt here",
         gollm.WithContext("Provide relevant context"),
         gollm.WithDirectives("Be concise", "Use examples"),
         gollm.WithOutput("Specify expected output format"),
     )

2. Utilize Prompt Templates:

   • For consistent prompt generation, create and use PromptTemplate objects.
   • Example:

     template := gollm.NewPromptTemplate(
         "CustomTemplate",
         "A template for custom prompts",
         "Generate a {{.Type}} about {{.Topic}}",
         gollm.WithPromptOptions(
             gollm.WithDirectives("Be creative", "Use vivid language"),
             gollm.WithOutput("Your {{.Type}}:"),
         ),
     )

3. Leverage Pre-built Functions:

   • Use provided functions like ChainOfThought() for complex reasoning tasks.
   • Example:

     response, err := tools.ChainOfThought(ctx, llm, "Your complex question here")

4. Work with Examples:

   • Use ReadExamplesFromFile() to load examples from files for consistent outputs.
   • Example:

     examples, err := utils.ReadExamplesFromFile("examples.txt")
     if err != nil {
         log.Fatalf("Failed to read examples: %v", err)
     }

5. Implement Structured Output:

   • Use WithJSONSchemaValidation() to ensure valid JSON outputs.
   • Example:

     response, err := llm.Generate(ctx, prompt, gollm.WithJSONSchemaValidation())

6. Optimize Prompts:

   • Utilize PromptOptimizer to refine prompts automatically.
   • Example:

     optimizer := optimizer.NewPromptOptimizer(llm, initialPrompt, taskDescription,
         optimizer.WithCustomMetrics(
             optimizer.Metric{Name: "Relevance", Description: "How relevant the response is to the task"},
         ),
         optimizer.WithRatingSystem("numerical"),
         optimizer.WithThreshold(0.8),
     )

7. Compare Model Performances:

   • Use CompareModels() to evaluate different models or providers.
   • Example:

     results, err := tools.CompareModels(ctx, promptText, validateFunc, configs...)

8. Implement Memory for Contextual Interactions:

   • Enable memory retention for maintaining context across interactions.
   • Example:

     llm, err := gollm.NewLLM(
         gollm.SetProvider("openai"),
         gollm.SetModel("gpt-3.5-turbo"),
         gollm.SetMemory(4096),
     )

9. Error Handling and Retries:

   • Always check for errors and configure retry mechanisms.
   • Example:

     llm, err := gollm.NewLLM(
         gollm.SetMaxRetries(3),
         gollm.SetRetryDelay(time.Second * 2),
     )

10. Secure API Key Handling:

    • Use environment variables for API keys.
    • Example:

      llm, err := gollm.NewLLM(
          gollm.SetAPIKey(os.Getenv("OPENAI_API_KEY")),
      )
