Use less
The greenest kilowatt-hour is the one you never spend. We default to the smallest capable model, quantise aggressively, batch requests, and cache. Efficiency comes first — before any offset is even counted.
The renewable AI assistant
Training a large language model can burn through the yearly electricity of hundreds of homes. We don't pretend otherwise. GreenAI runs on renewable power, routes every question to the leanest model that can answer it, and funds new renewable capacity until the balance tips positive.
No carbon guilt bolted on afterwards — energy accounting is built into how the product works.
The honest bit
A single frontier model can take tens of gigawatt-hours to train — comparable to the annual electricity use of a small town — and every message you send afterwards draws a little more. Most AI companies quietly buy offsets and move on. We think the honest response is to measure it, minimise it, and then over-correct until the numbers point the other way.
Our approach
The greenest kilowatt-hour is the one you never spend. We default to the smallest capable model, quantise aggressively, batch requests, and cache. Efficiency comes first — before any offset is even counted.
Inference runs in datacentres powered by wind, solar and hydro, matched to real generation hour-by-hour where we can, not just annual averages. We publish where our compute physically runs.
A fixed share of every subscription funds new renewable projects — community solar, wind, storage — sized to repay training and then keep going. The goal is net-positive, not net-zero.
The models we run
Bigger isn't greener. Most questions are handled beautifully by compact, open models running quantised on modest hardware. We route heavier reasoning to larger models only when a task genuinely needs it.
Fast, capable general chat at a fraction of frontier-model energy. Our default for most conversations.
Tiny variants run on very little power for quick lookups, drafting and summarising.
Strong coding and non-English performance without reaching for a giant model.
Google's compact open models — excellent quality per watt for structured tasks.
Punches well above its size on maths and logic, so we rarely escalate.
For genuinely hard reasoning and long context. Used only on escalation, so its bigger draw stays the exception, not the default.
Reserved for complex code and analysis that the compact models can't finish cleanly on their own.
A mixture-of-experts model that only activates ~37B parameters per token, so it delivers frontier quality at a fraction of a dense model's energy.
Our top tier for the hardest problems. Powerful but power-hungry, so the router reaches for it rarely — and always tells you when it did.
A trillion-parameter mixture-of-experts model that lights up just 32B parameters per token — frontier-scale reasoning without frontier-scale energy per query.
A lightweight router reads your request and sends it to the leanest model likely to nail it — escalating to the heavier models above only when confidence is low. You always see which model replied.
Our green credentials
Borrowed from the honest tradition of green infrastructure: state what's genuinely clean, and be candid about what still isn't.
Inference is placed in datacentres on renewable power-purchase agreements — onshore and offshore wind, solar and hydro — chosen for a low PUE (target under 1.2) so less energy is lost to cooling and overhead.
Smallest capable model, 4-bit quantisation, request batching and response caching. Every optimisation that cuts a watt ships before we count a single offset.
We fund additional renewable generation and storage that wouldn't otherwise exist, sized to repay our training energy and then run net-positive. Certificates alone don't count.
An annual energy report, and a per-conversation estimate you can open any time. If you can't see the numbers, it isn't accountability.
Grid mixes still aren't 100% renewable everywhere our compute lands. Hardware carries embodied carbon from manufacturing. We don't control upstream chip fabrication. We'd rather name these than airbrush them.
Our methodology and offset partners will be listed publicly. Hold us to the net-positive claim — that's the whole point of publishing it.
Start a conversation for free. Every chat shows which model answered and roughly what it cost in energy — with renewable investment already covering more than the draw.
We'll only email you about your early access. No spam, ever.
