Compute Cost Meter for ChatGPT

Estimates compute hardware plus electricity cost from ChatGPT response time.

See an estimated monetary cost for the infrastructure used while ChatGPT generates a response. The extension measures how long a ChatGPT response is generating and converts that elapsed time into an estimate made up of compute hardware cost and electricity cost. Features include a live running total, compute/electricity breakdown, currency selection, floating counter, toolbar badge, and reset option. No API or token pricing is used. The estimate is a proxy only. ChatGPT does not expose its actual per-request GPU allocation, batching, utilisation, data-centre location, or electricity contract. This extension is independent and is not affiliated with or endorsed by OpenAI. **New (v1.2.0) New: Automatic Update Notifications We've introduced a new way to keep users informed whenever Compute Cost Meter receives an update. Update Notifications: A one-time notification appears after a new extension version is installed. What's New Highlights: See a summary of new features, improvements and fixes. Dismiss Once: Click "Got it" to dismiss the notification permanently for that version. Non-Intrusive Design: Notifications integrate with the existing interface without interrupting ChatGPT. Release Notes: Review update information directly from the extension popup. Additional Improvements Preserved the original black-and-yellow lightning design. Maintained daily, session and all-time cost tracking. Retained detailed compute and electricity cost breakdowns. No changes to the underlying calculation methodology. No additional browser permissions required. No external tracking, advertising or analytics. (v1.1.2) Greater Cost Precision: Individual compute and electricity costs now display six decimal places for more accurate-looking breakdowns. Compact Interface: Optimised the extension popup to reduce unnecessary scrolling. UI Refinements: Improved spacing and readability while maintaining the original design.
