datasette-demo-for-llm-accountant

Demo app for LLM accountant

This is a demonstration plugin showing how to use datasette-llm-accountant to track and log LLM API costs.

Features

• Interactive LLM Form: Submit prompts to any available LLM model via a web interface
• Cost Tracking: All LLM API calls are tracked with nanocent precision
• Transaction Log: View a running total of all LLM requests and their costs
• In-Memory Accountant: Demonstrates implementing a custom Accountant subclass

Installation

Install this plugin in the same environment as Datasette.

datasette install datasette-demo-for-llm-accountant

Usage

Once installed, navigate to /-/llm-accountant in your Datasette instance.

You'll see:

1. A form to select an LLM model and enter a prompt
2. The response from the LLM
3. A transaction log showing all requests and their costs

Each request reserves $0.50 by default, and the actual cost is calculated based on token usage and settled in the transaction log.
