Generative AI
Beginners Guide 2025
Master the latest AI tools, prompting techniques, and advanced features transforming business in 2025
What is Generative AI?
Generative AI creates new content—text, images, code, or data—based on patterns learned from vast amounts of training data. Unlike traditional AI that analyzes or classifies, generative AI produces original outputs.
Key Capabilities in 2025
- Multimodal Understanding: Process text, images, audio, and video simultaneously
- Advanced Reasoning: Chain-of-thought problem solving with transparent logic
- Function Calling: Interact with external tools and APIs
- Real-time Learning: Adapt and improve based on feedback

Advanced AI Concepts
Unlock the full potential of modern AI with these cutting-edge features and techniques.
Function Calling
AI models can now call external functions and APIs to perform specific tasks, enabling them to interact with databases, send emails, or retrieve real-time information.
Use Cases:
- Call weather API to get current conditions
- Send calendar invitations through email API
- Query database for customer information
- Execute calculations or data processing
Example Implementation:
{
"name": "get_weather",
"description": "Get current weather for a location",
"parameters": {
"type": "object",
"properties": {
"location": {"type": "string"},
"units": {"type": "string", "enum": ["celsius", "fahrenheit"]}
}
}
}Model Context Protocol (MCP)
A standardized way for AI models to connect with various data sources and tools, enabling seamless integration across different systems and platforms.
Use Cases:
- Connect to multiple databases simultaneously
- Integrate with CRM systems
- Access file systems and documentation
- Link with project management tools
Example Implementation:
// MCP Connection Example
const mcpClient = new MCPClient({
transport: "stdio",
capabilities: ["resources", "tools", "prompts"]
});
await mcpClient.connect("filesystem://docs");Advanced Reasoning
Modern AI models can perform chain-of-thought reasoning, breaking down complex problems into steps and providing transparent thinking processes.
Use Cases:
- Multi-step mathematical problem solving
- Complex business analysis with justification
- Legal document analysis with reasoning
- Strategic planning with step-by-step logic
Example Implementation:
Prompt: "Think step by step to solve this problem: A company has 3 offices with different costs... Response: Let me break this down: Step 1: Calculate costs for each office Step 2: Compare efficiency metrics Step 3: Factor in growth projections Step 4: Make recommendation with reasoning"
Deep Research
AI models can now conduct comprehensive research by accessing multiple sources, synthesizing information, and providing detailed analysis with citations.
Use Cases:
- Market research with multiple data sources
- Competitive analysis across industries
- Technical documentation synthesis
- Trend analysis with supporting evidence
Example Implementation:
Research Query: "Analyze the AI automation market trends for 2025" AI Response: - Searches multiple databases - Synthesizes findings from reports - Provides citations and sources - Identifies key trends and patterns
