One subscription,
the whole model spectrum.

Set up in three steps, about five minutes

No credit card or currency exchange needed. Even first-time users can complete setup on their own by copying from the guide.

What it looks like once connected

It is the tool you already use — same interface, same commands. Only the models and quota behind it come from here.

Most common tools connect directly

We support both the OpenAI and Anthropic API formats. Any tool that lets you change its endpoint works by pointing that setting at us, with no plugin to install. Click the tool you use to see its guide.

Prism sends each task where it belongs

Everyday tasks vary widely in difficulty. Running both a variable rename and a module refactor on the most expensive model wastes a lot of money.

Prism is our routing layer. Every request passes through it first, gets assessed for difficulty and required capabilities, then lands at the right point on the spectrum. Use the auto preset we maintain, or write your own rules.

You can also choose the model yourself

One model field, two ways to use it: name a specific model and it's pinned to that one; put auto or your own custom model name there and Prism routes it. Switching between the two changes nothing else — no reconfiguration, no code churn.

model: "model-a"        // Pinned to this model, Prism stays out of it
model: "auto"           // Handed to Prism, picked by task difficulty
model: "coder"          // Your own custom model, your own rules

Custom models: a model chosen for each turn

Answer four questions to create a custom model name, such as coder. When you call it, work that needs aesthetic judgment or is difficult goes to a strong model, clearly simple work goes to a cheaper one, and everything else goes to the default you chose. Every rule and threshold is laid out in the console; replay a change against your own traffic, then save it as a new version.

Routing by task type is not open yet. You can already create and call a custom model; until it opens, every turn goes to the model you set for “when unjudged”, with no changes needed once it does.

Cheaper must never mean worse. When difficulty is near a boundary, auto always picks the stronger model; this rule is fixed. In a custom model you set the balance: work goes to a cheaper model only as far as you tilt it toward cost, and every such decision is recorded in the routing trace.

We don't compete on price. We focus instead on reliable supply, clear billing, and taking responsibility when problems occur.

The low end uses our users' actual average on frontier models over the last 30 days; the high end applies the same usage to the cheapest text model on sale right now. Both include the context each request carries. Quota is drawn in CU by usage, never by request count; see the Models page for each model's per-token rates.

Your code and prompts are not stored by default

What you send us is often your most sensitive material, including source code, internal documents and client data. Here is how we handle it.

Your request bodies have a market price

This rarely gets said out loud. Every prompt and every file a user sends can be recorded in full — distilled into smaller models, packaged and sold as training data, or quietly traded between platforms. No notification is sent, and the terms usually contain no explicit prohibition.

The internal documents, client data and unreleased code you pasted in may already be in somebody's training set.

We oppose this practice and back that up with the measures below.

1. 01

   Zero retention is architecture, not policy

   There is no code path in the gateway that writes a request body anywhere; the system has nowhere to store bodies, and that can be verified by audit.

2. 02

   We buy no data of unclear origin

   We purchase request corpora from no platform and no data broker, at any price, under any label.

3. 03

   We refuse data-for-price deals

   When a provider offers a lower rate in exchange for data sharing, we decline.

4. 04

   We accept verification

   All of this goes into the terms of service with legal force. We accept third-party security audits, and you're welcome to inspect the traffic yourself.

We can't change the whole industry, but we can guarantee that data passing through our gateway goes nowhere else.
