Step-by-Step Tutorial: Building a Real-Time AI Chatbot with Gemini 1.5 Flash

Google's Gemini 1.5 Flash model delivers sub-second inference speeds and massive 1M token context windows at a fraction of standard API costs.

1. Gemini 1.5 Flash API Initialization

Configure the @google/genai SDK with system instructions, structured output schemas, and dynamic temperature controls.

2. Real-Time Token Streaming Setup
