🎯 Objective: Master the Model Catalog and test your first AI model
The Model Catalog is your gateway to the AI ecosystem. It aggregates models from multiple providers, making it easy to discover and compare options.
🔍 Navigation Guide:
Click on MODELS - Catalog in the AI Toolkit sidebar
💡 Pro Tip: Look for models with specific capabilities that match your use case (e.g., code generation, creative writing, analysis).
Model Selection Strategy:
- GPT-4.1: Best for complex reasoning and analysis
- Phi-4-mini: Lightweight, fast responses for simple tasks
🔧 Configuration Process:
- Select OpenAI GPT-4.1 from the catalog
- Click Add to My Models - this registers the model for use
- Choose Try in Playground to launch the testing environment
- Wait for model initialization (first-time setup may take a moment)
⚙️ Understanding Model Parameters:
- Temperature: Controls creativity (0 = deterministic, 1 = creative)
- Max Tokens: Maximum response length
- Top-p: Nucleus sampling for response diversity
The Playground is your AI experimentation lab. Here's how to maximize its potential:
🎨 Prompt Engineering Best Practices:
- Be Specific: Clear, detailed instructions yield better results
- Provide Context: Include relevant background information
- Use Examples: Show the model what you want with examples
- Iterate: Refine prompts based on initial results
🧪 Testing Scenarios:
# Example 1: Code Generation
"Write a Python function that calculates the factorial of a number using recursion. Include error handling and docstrings."
# Example 2: Creative Writing
"Write a professional email to a client explaining a project delay, maintaining a positive tone while being transparent about challenges."
# Example 3: Data Analysis
"Analyze this sales data and provide insights: [paste your data]. Focus on trends, anomalies, and actionable recommendations."🎯 Goal: Compare different models using identical prompts to understand their strengths
📋 Instructions:
- Add Phi-4-mini to your workspace
- Use the same prompt for both GPT-4.1 and Phi-4-mini
- Compare response quality, speed, and accuracy
- Document your findings in the results section
💡 Key Insights to Discover:
- When to use LLM vs SLM
- Cost vs. performance trade-offs
- Specialized capabilities of different models
🎯 Objective: Create specialized AI agents tailored for specific tasks and workflows
Agent Builder is where AI Toolkit truly shines. It allows you to create purpose-built AI assistants that combine the power of large language models with custom instructions, specific parameters, and specialized knowledge.
🧠 Agent Architecture Components:
- Core Model: The foundation LLM (GPT-4, Groks, Phi, etc.)
- System Prompt: Defines agent personality and behavior
- Parameters: Fine-tuned settings for optimal performance
- Tools Integration: Connect to external APIs and MCP services
- Memory: Conversation context and session persistence
