By Kith Climate · for everyone who's said AI's footprint matters
Set the standard. Reduce your AI climate impact by 60%+ today.
What's stopping everyone from using Tret? The answer we're pursuing: nothing. Cheaper and often better — plus there's an open source version.
Your climate-friendly AI wrangler
“I've gotten to rely on Claude or GPT for help. But I can't look past the water and climate impact. Why isn't there a better alternative?”
heard across the kith climate community
We heard this from so many Kith Climate community members that we committed our own tech resources to a solution. As a small AI venture, it wasn't easy — but it was worth it.
An intelligent AI model wrangler. Like the AI assistants you already use, it helps you get work done. The difference is measurable impact — and cost.
That's because Tret harnesses more carbon-efficient open source models, and makes use of “lighter” models where possible. All without sacrificing quality.

MistralTwo things happened. Open source models closed the quality gap — on most everyday tasks they now match frontier caliber. The energy gap, though, never closed: the heaviest model can emit many times more per answer than the lightest one able to do the same job.
That gap is the opportunity. Map the tool to the task — heavy models only where the work demands them — and the savings fall out. That's all Tret does, on every call.
heaviest vs lightest model, same family
heaviest frontier model vs its open source alternative
same task · three capable models
multiples and gCO₂e are estimates derived from published price and compute figures · derivations in the docs
01 · ask
Memos, analysis, drafts, review — the same daily work, in a chat that behaves the way you expect.
02 · route
Open models now match frontier caliber on most tasks at a fraction of the energy. Tret knows which, when — and escalates only when the work demands it.
03 · receipt
Every answer carries its receipt. Your month rolls up into totals you can stand behind — and show.
Ask like you would anywhere else. Tret profiles the task, routes it, and hands back the answer with its footprint attached.
Never say “green” where you can show the receipt.
Turn these site-visit notes into a briefing for the county board.
Briefing drafted — two pages, plain language, every figure sourced from your notes. Want it as a memo or slides?
Your monthly receipt exports as a card. Post it where your field can see it — the norm changes when the numbers are public.
