# Provider pricing

What our model providers charge, and where the authoritative numbers live.

## The authority

**The gateway's own per-model costs are the authority** — they are what the
response headers (`x-litellm-response-cost`) and member billing both read. They
live in the LiteLLM config on the gateway's persistent volume
(`/app/data/config.yaml`), under each model's `model_info`, as **USD per token**
(the comments in that file quote per-1M rates). Read them live with
`GET https://gateway.inference.coop/model/info` (master key), or read the config
straight from the running app.

**The member-facing mirror** is `co-op/docs/models.md`. When a rate changes,
update **both** the gateway config and `models.md` — the config is authoritative,
`models.md` is the mirror.

A missing cost field makes a paid feature free; a stale one bills wrong; a missing
`cache_read_input_token_cost` bills cache hits at the full input rate. All three
have happened here.

## The pages

| File | Provider | Notes |
|---|---|---|
| `greenpt.md` | GreenPT | renewable energy; the default model lives here |
| `tinfoil.md` | Tinfoil | TEE; the local-proxy architecture lives here |
| `regolo.md` | Regolo | renewable + ZDR; includes our measured usage |
| `decision-model.md` | GreenPT "Metis" via `/v1/systemone` | a pass-through **route**, not a chat model |

## The routing rule

Members reach models through one gateway, which fronts all providers. The
per-request cost the gateway records is the number to trust; do not re-derive a
price from a provider's public page (they drift, and some are login-walled).

## A note on currencies

Regolo quotes in **EUR**; our gateway figures convert at **EUR × 1.16 → USD**
(the rate our numbers use — `regolo.md` documents the derivation). GreenPT's own
listed rates appear in **EUR with the same numerals the gateway carries** —
whether an EUR→USD conversion is intended there is **unverified**; confirm it
against the GreenPT invoice before treating the figures as final.
