[Problem] I wanted to track how many tokens I am burning and it's estimated energy and water impact.

[WHAT THIS IS] A local token usage tracker that works across different coding harnesses and estimates energy and water impact

[MY EXPERIENCE] Tracking this really put things into perspective. My personal usage is close to 1 MWh in the past three months which I had no idea about. This does not include my AI usage at work which is probably 10x.

[DEMO] If you are interested in tracking these numbers locally, try out: https://ai-meter.app

- It reads historical data if the files are present. Works completely locally (except to check if there is an update for the widget) - No login. No analytics. No tracking.

[On estimates]

AI Meter measures tokens from local AI coding-tool logs, then estimates:

Electricity: tokens ÷ 1M × 0.39 kWh, calibrated from Oviedo et al.’s production-scale inference model.

Direct cooling water: electricity ÷ 1.20 PUE × 0.45 L/IT-kWh, using LBNL’s U.S. data-center WUE scenario.

These are adjustable estimates, not provider measurements. They exclude training, hardware manufacturing, electricity-generation water, and local-device energy.

Hope you find this interesting! Please feel free to give feedback, would love to make this better!

Hi all! I'm excited to tell you about a website I made, aiming to be the easiest and fastest way to learn about more than 100 different theories of society (e.g., what exactly each claims about how society does and should work, including written explanations and visual diagrams that go along with them). It includes, among many others:

Adam Smith: https://society.clearerthinking.org/#adam_smith

Paul Graham: https://society.clearerthinking.org/#paul_graham

Tyler Cowen: https://society.clearerthinking.org/#tyler_cowen

Peter Thiel: https://society.clearerthinking.org/#peter_thiel

If you find any errors, please let me know.

Thanks!

-Spencer

The V8.2 making it the default model on Midjourney. This is a release focused on aesthetics, personalization, and image quality. Our new style is more creative, bold, edgy and fresh and personalization works better than ever.
