# ⚡ Model Registry Optimization (Fast Mode)

## Changes
- **Removed Llama 3.3 70B**: Deprecated due to stability issues in structured output (Ref: agno-agi/agno#4090).
- **Added Qwen 2.5 32B (`qwen-2.5-32b`)**: New default for Fast Mode. Chosen for its superior performance in JSON generation and logic reasoning at lower latency.
- **Added GPT-OSS 20B (`openai/gpt-oss-20b`)**: Lightweight alternative for ultra-fast data retrieval tasks.
-- update README.md

## Impact
- Improves "Fast Mode" stability for Tool Calling (Scout/Navigator).
- Reduces latency for intermediate reasoning steps.

+# ✨ LifeFlow AI: Intelligent Trip Planning System
+
+> **Your journey, in perfect rhythm.** > An enterprise-grade, multi-agent system that orchestrates your daily schedule using real-world data, hybrid AI architecture, and mathematical optimization.
+
+---
+
+## 📖 Overview
+
+**LifeFlow AI** is not just a chatbot; it's a **State Machine for Real-World Operations**. It solves the complexity of daily travel planning—considering traffic, weather, opening hours, and route optimization—by coordinating a team of specialized AI agents.
+
+Unlike traditional AI planners that hallucinate locations, LifeFlow grounds every decision in **Real-Time Data** (Google Maps & OpenWeather) and uses **Mathematical Optimization** (TSP/OR-Tools) for routing.
+
+## 🚀 Key Innovation: Hybrid AI Architecture
+
+We solve the "Trilemma" of AI Agents: **Cost vs. Speed vs. Intelligence**.
+
+### 1. Dual-Brain System 🧠 + ⚡
+Instead of using one expensive model for everything, LifeFlow uses a tiered approach:
+* **Primary Brain (The Leader):** Uses high-reasoning models (e.g., **GPT-5, Gemini 2.5 Pro**) for complex intent understanding, team orchestration, and final report generation.
+* **Acceleration Layer (The Muscle):** Uses ultra-fast, low-cost models (e.g., **Groq/Llama-3, Qwen 2.5, Gemini Flash-lite, GPT mini**) for high-volume tool execution (searching POIs, checking weather).
+
+### 2. Context-Offloading Protocol 📉
+Traditional agents paste massive JSON search results into the chat context, burning thousands of tokens.
+* **LifeFlow's Approach:** Agents treat data like "Hot Potatoes."
+* **Mechanism:** Raw data (reviews, photos, coordinates) is offloaded to a structured database immediately. Agents only pass **Reference IDs** (e.g., `scout_result_123`) to the next agent.
+* **Result:** Token consumption reduced by **75%** (from ~80k to ~20k per run).
+
+---
+
+## 🤖 The Agent Team
+
+LifeFlow orchestrates 6 specialized agents working in a strict pipeline:
+
+1.  **📋 Planner:** Analyzes vague user requests (e.g., "I need to buy coffee and visit the bank") and converts them into structured JSON tasks.
+2.  **👨‍✈️ Team Leader:** The State Machine orchestrator. Enforces SOPs and handles error recovery.
+3.  **🗺️ Scout (Fast Mode):** Interacts with Google Places API to verify locations and retrieve coordinates.
+4.  **⚡ Optimizer (Fast Mode):** Uses routing algorithms to solve the *Traveling Salesperson Problem (TSP)* with time windows.
+5.  **🧭 Navigator (Fast Mode):** Calculates precise traffic impacts and generates polyline routes.
+6.  **🌤️ Weatherman (Fast Mode):** Checks hyper-local weather forecasts for specific arrival times.
+7.  **📊 Presenter:** Compiles all data (from the DB) into a human-readable, formatted report.
+
+---
+
+## 🛠️ Features
+
+* **BYOK (Bring Your Own Key):** Secure client-side key management for Google Maps, OpenWeather, and LLMs.
+* **Zero-Cost Validation:** Smart API testing mechanism that checks key validity without incurring charges.
+* **Interactive Map:** Visualizes routes, stops, and alternative POIs using Folium.
+* **Graceful Cancellation:** Cooperative signal handling to terminate background agents instantly.
+* **Reactive UI:** Modern Gradio interface with real-time streaming and responsive layouts.
+
+---
+
+## ⚙️ Configuration
+
+LifeFlow AI allows deep customization via the **Settings** panel:
+
+### Supported Providers
+* **Google Gemini:** 2.5 Pro, 2.5 Flash, 2.0 Flash.
+* **OpenAI:** GPT-5, GPT-5-mini, GPT-4o-mini.
+* **Groq:** Llama 3.3 70B, Qwen 2.5 32B (for Acceleration).
+
+### Fast Mode (Hybrid)
+Enable **Fast Mode** in settings to offload search and routing tasks to Groq. This significantly reduces latency and API costs while maintaining high-quality reasoning for the final output.
+
+---
+
+## 📦 Tech Stack
+
+* **Framework:** [Agno](https://github.com/agno-agi/agno) (formerly Phidata) for Agent Orchestration.
+* **UI/UX:** Gradio 5.x with custom CSS themes. (update to Gradio 6.x soon)
+* **Services:** Google Maps Platform (Places, Routes), OpenWeatherMap.
+* **Infrastructure:** Python 3.11, Docker.
+
