Intelligence shouldn't
cost the earth.

Adaptive AI infrastructure that routes every query to the smallest model that can answer it, and shows you exactly what it cost the planet.

Every AI query consumes energy.
Most of it unnecessarily.

more energy, GPT-4 uses vs a small model on the same simple query

of queries on ATHENA include an energy cost in the response

How it works

Query arrives

Your question enters the network. You don’t choose a model.
You don’t think about infrastructure. You just ask.

ATHENA ROUTER

Tier 1 (0–0.30)Tier 2 (0.30–0.65)Tier 3 (0.65–1.0)

Complexity scored

The router analyzes your query in milliseconds. Code, math,
simple lookup, complex reasoning, each gets a complexity
score from 0 to 1. The score determines the tier.

Minimum model selected

The smallest model that can handle your query answers it.
Not the largest. Not the default. The minimum capable
model. Every time.

You see the cost

Every response includes the energy used, the carbon emitted,
and what you saved by not using a larger model. No estimates
buried in annual reports. Right there. Every query.

Built for two kinds of people

Developers

Adaptive routing API

Drop-in replacement for direct model calls. The router handles tier selection. Your code doesn't change.

Full metadata on every response

Compute units, energy, CO₂, routing confidence, latency. In the response body. Every time.

Usage dashboard

Query volume, tier distribution, cost and energy over time. Exportable.

Model preferences

Choose preferred models per tier, sorted by environmental impact score.

Everyone else

Chat interface

Ask anything. See the energy cost of every response. Compare what you used to what you would have used.

Eco mode

Caps routing at Tier 2. Lower energy, still capable. One toggle.

Impact score

Every query gets a score. See the data center it went through and the grid it ran on.

Monthly impact report

What your AI use cost the planet this month, and what you saved.
