Newsletter
One number a month
The Green Tokens edition is deliberately short: one number from the index, one note on what moved it or what it means, and one pointer to something worth reading. If the index did not change, the note says so. No round-ups, no sponsors.

Email edition
The email edition is being set up. Until it opens, the meter runs inside Own Your AI, the fortnightly LinkedIn newsletter, which will carry one number from this index in every issue from its next edition.

What an edition looks like
Sample, built from the current index
The number. 63.5 Wh per million output tokens: Qwen 3 32B on 2 × H100, the index's reference row, at a running batch of 256 and 44 ms median inter-token latency.
The note. The same model on the same cards reads 452 Wh/M at a running batch of 8. The 7.1× between those two rows is not the model and not the hardware. It is how busy the server was.
The pointer. ML.ENERGY Leaderboard v3.0, Text Conversation tab, sorted by energy per token, with the About tab open beside it for the method.
Cadence. Monthly, on the first working day, or sooner when a measurement lands that changes a tile. Length. Under 200 words. Archive. Every edition is posted to the blog the same day, so the RSS feed carries them too.
Own Your AI. Prem Naraindas's fortnightly LinkedIn newsletter on sovereign AI will carry a three-line "meter" block with one reading from this index in every issue, from its next edition. The two do not overlap: Own Your AI is about control, this one is about energy.
