# The same work, for less.

Smaller models need less compute, and we pass that on. We bill per turn, so you know what a conversation costs before it starts.

## Long conversations don’t get more expensive

Most models process the whole conversation again on every turn. The longer it runs, the more each turn costs.

tbd-0 works with a context of constant size. Turn 50 costs the same as turn 1.

## Where else the savings come from

### Smaller models

Instead of one giant model for everything, tbd-0 uses models sized for the job. Less compute per answer means a lower price.

### Expert models

For work in a specific field, a small expert model outperforms a large general-purpose one. You don’t pay for knowledge you don’t need.

### Per-turn billing

We bill per model turn, not per token. Long prompts and long conversations don’t lead to surprises on the invoice.

### No switching cost

Our API is compatible with the OpenAI Responses API. Testing tbd-0 against your current setup takes one line.
