Send one request
Point your app at a single Athena endpoint. No per-provider SDKs, keys, or routing logic to maintain.
Adaptive AI gateway
ATHENA
Route every query to the model that should answer it.
Athena Router is Aletheon's adaptive AI gateway. It sends each request to the smallest, most efficient model that can handle it, across 8 providers and ~19 models, so you cut AI cost and energy use without compromising quality.

How it works
One endpoint. The right model, every time.
02
Athena picks the model
Every request is scored and routed to the smallest, most efficient model that can answer it well, across 8 providers and ~19 models.
03
You get the answer and the receipt
Back comes the response plus the exact cost and carbon of that call, with automatic failover if a provider is down.
What you get
Lower cost and energy, not lower quality.
8 providers, one API
Anthropic, OpenAI, Google, Groq, Mistral and more behind a single, stable interface.
Cost-aware routing
Cut spend by sending easy queries to small models and reserving frontier models for hard ones.
Cost and carbon on every call
Full transparency: see the price and the estimated energy of each request in your dashboard.
Automatic failover
If a provider degrades or errors, Athena reroutes in real time so your product stays up.
Athena also includes a chat interface, a usage dashboard, and tiered billing, so teams can use it directly or wire it into their own products.
