Visualizing LLM API Price Volatility: An Open-Source Tool to Justify Local Compute Budgets

olddoglearnsnewtrick · reddit · 2026-08-08

A developer shared their experience of successfully securing a budget for local compute resources from management. They noted that arguing for data sovereignty often fails, but demonstrating the unpredictable and uncontrollable pricing of LLM APIs works.

To illustrate this, they built an open-source static web tool visualizing the price fluctuations of major LLMs (like the Anthropic family) over the past couple of years. This visualization clearly highlights the disadvantage of relying on opaque API pricing. The project is hosted on GitHub Pages, and the codebase is open-source for the community to use and improve.
