- **Monthly cost tracking** - Automatically resets each month
- **Daily cost tracking** - Shows today's spending
- **Per-message costs** - Individual message cost breakdown
- **Token usage** - Input and output token counts
- **Multi-provider support** - Works with OpenAI, Anthropic, Gemini, and more
## 🚀 Features
- 📊 **Real-time cost tracking** with status messages
- 🗓️ **Automatic monthly/daily reset** - No manual maintenance
- 🔧 **Easy configuration** via JSON valve

## 📋 Installation
1. Download `simple_cost_tracker.py`
2. In Open WebUI, go to **Admin Panel > Functions**

"anthropic.claude-3-5-haiku-latest": {"input": 0.80, "output": 4.0},
"google.gemini-2.5-flash": {"input": 0.30, "output": 2.50}
}
```
**Important:** Use the exact model name as shown in **Settings > Models**. Include connection prefixes if you use them.
For initial costs, edit `cost_tracker_data.json` file manually, costs will add up as you use the function.

```
0.0052 € this message, 0.47 € today, 13.20 € this month. 11746 tokens used (11313 in, 433 out)
```
## 📁 Data Storage
Costs are stored in `cost_tracker_data.json` with automatic:
- Monthly reset on the 1st of each month
- Daily reset at midnight
- Persistent tracking across sessions
