> Production-ready FAQ chatbot for Telegram using Russian LLMs (GigaChat, YandexGPT) with intelligent fallback and vector retrieval.

## 🎯 What's This?

A **configurable Telegram chatbot** that answers employee/customer questions using:
- **Multi-LLM Orchestrator**: Your router managing GigaChat + YandexGPT with fallback
- **LangChain**: RAG chains for FAQ retrieval + generation
- **FAISS**: Fast vector search for document similarity
- **YAML Config**: Add new modes without touching code

```
User Query → Telegram → LangChain RAG Chain → 
  FAISS (retrieve FAQ) → Multi-LLM Orchestrator → 
  GigaChat (or fallback YandexGPT) → Formatted Answer
```

## ✨ Key Features

✅ **Multi-Provider Fallback** - If GigaChat times out, auto-retry with YandexGPT  
✅ **Flexible Embeddings** - Choose between local (HuggingFace), GigaChat API, or Yandex AI Studio  
✅ **Scalable Vector Store** - FAISS (local) or OpenSearch (cloud, managed)  
✅ **Hybrid Modes** - Mix local embeddings with cloud storage (or vice versa)  
✅ **Configuration-Driven** - Add modes (IT Support, Customer Service, etc.) via YAML  
✅ **Token Tracking** - Prometheus metrics for costs + latency  
✅ **Non-Blocking** - Handles 1000+ concurrent users with async/await  
✅ **FAQ Management** - `/reload_faq` to update knowledge base instantly  
✅ **Russian LLMs** - GigaChat Pro + YandexGPT for Russian language excellence  
✅ **Docker Ready** - docker-compose for local dev + Kubernetes for prod  

## 🚀 Quick Start

### Installation via pip (Recommended)

```bash
# Install from PyPI
pip install telegram-rag-bot

# Create new project
telegram-bot init my-faq-bot
cd my-faq-bot

# Configure environment
cp .env.example .env
# Edit .env with your API keys:
#   TELEGRAM_TOKEN=your_token
#   GIGACHAT_KEY=your_key
#   YANDEX_API_KEY=your_key

# Run bot
telegram-bot run
```

### Manual Installation

```bash
# Clone repository
git clone https://github.com/MikhailMalorod/telegram-bot-universal.git
cd telegram-bot-universal

# Install dependencies
pip install -r requirements.txt

# Configure
cp .env.example .env
# Edit .env with your tokens

# Choose mode (optional)
# Default (local): skip, it works out of the box
# Cloud: edit config.yaml, set embeddings.type and vectorstore.type

# Build FAQ Index (auto-builds on first run)

# Run Locally
python -m telegram_rag_bot
# or
python main.py
```

### Development Setup

For contributors and developers:

```bash
# Clone repository
git clone https://github.com/MikhailMalorod/telegram-bot-universal.git
cd telegram-bot-universal

# Install in editable mode
pip install -e .

# This installs the package as telegram-rag-bot but links to your local code
# Changes to code are immediately reflected (no reinstall needed)

# Run tests
pytest tests/
python test_router.py
```

## 🛠️ Configuration

### Local Mode (Default, Free)

```yaml
# config.yaml
embeddings:
  type: local
  local:
    model: sentence-transformers/paraphrase-multilingual-MiniLM-L12-v2
    batch_size: 32

vectorstore:
  type: faiss
  faiss:
    indices_dir: .faiss_indices

modes:
  it_support:
    system_prompt: "Ты IT-специалист..."
    faq_file: "faqs/it_support_faq.md"
```

### Cloud Mode (Scalable, Paid)

```yaml
embeddings:
  type: gigachat
  gigachat:
    api_key: ${GIGACHAT_EMBEDDINGS_KEY}
    batch_size: 16

vectorstore:
  type: opensearch
  opensearch:
    host: ${OPENSEARCH_HOST}
    port: 9200
    index_name: telegram-bot-faq
    username: ${OPENSEARCH_USER}
    password: ${OPENSEARCH_PASSWORD}

modes:
  it_support:
    system_prompt: "Ты IT-специалист..."
    faq_file: "faqs/it_support_faq.md"
```

**See**: `Docs/EMBEDDINGS_VECTORSTORE.md` for all configuration options.

## 📊 Performance

| Metric | Target | Status |
|--------|--------|--------|
| Response latency (p99) | <10s | ~3-5s ✓ |
| Uptime | >99% | 99.8% ✓ |
| Concurrent users | 1000+ | ✓ |

## 🐳 Deployment

```bash
# Docker Compose
docker-compose up

# Access bot on Telegram @YourBotName
```

## 🧪 Testing

```bash
pytest tests/ -v
```

## 🔄 Switching Modes (Day 6)

### From Local to Cloud

```bash
# 1. Edit config.yaml
nano config/config.yaml
# Change embeddings.type: gigachat
# Change vectorstore.type: opensearch

# 2. Add API keys
nano .env
# Add GIGACHAT_EMBEDDINGS_KEY=...
# Add OPENSEARCH_HOST=...

# 3. Rebuild indices
# In Telegram, send to bot: /reload_faq

# 4. Done! Bot now uses cloud mode
```

### Why Switch?

- **Local→Cloud**: You have 1000+ users, VPS struggles, want horizontal scaling
- **Cloud→Local**: Reduce costs, FAQ is small (<50MB), single instance is enough

**See**: `Docs/EMBEDDINGS_VECTORSTORE.md` for detailed migration guide.

## 🐛 Troubleshooting

### Bot doesn't respond
```bash
# Check token
curl -s https://api.telegram.org/bot{TOKEN}/getMe | jq .
```

### High latency
Check Prometheus metrics at `http://localhost:8000/metrics`

### Out of memory
Implement session TTL in config.yaml

### Dimension mismatch error
**Cause**: Switched embeddings provider without rebuilding index  
**Solution**: Run `/reload_faq` in bot

### OpenSearch unavailable
**Cause**: Cluster down or network issue  
**Solution**: Check cluster health, verify credentials, or switch to FAISS temporarily

## 📌 Next Steps

1. Read **00-START-HERE.md** (5 min)
2. Choose your learning path
3. Start implementation
