# GreenPT pricing

GreenPT is OpenAI-compatible, EU-hosted on **100% renewable energy**. LiteLLM
talks to it **directly** (no TEE proxy). Billing across the gateway:

- `api_base`: `https://api.greenpt.ai/v1`
- key: `GREENPT_API_KEY` (gateway app env)

## What we serve, and what it costs

Rates as recorded in the gateway's authorititative config comment, **USD per 1M
tokens** (the gateway's `model_info` carries the per-token equivalents):

| our model | input | output | cached input |
|---|---|---|---|
| `greenpt/deepseek-v4.1-flash` **(DEFAULT model)** | $0.22 | $1.10 | $0.011 |
| `greenpt/glm-5.3-flash` | $0.11 | $0.44 | $0.022 |
| `greenpt/glm-5.3` | $1.10 | $4.40 | $0.275 |

- **`greenpt/deepseek-v4.1-flash` is the gateway's default model.** It is the same
  model family as Tinfoil's `tinfoil/deepseek-v4-1-flash`, but on renewable energy
  and **not** marked "Experimental" by the provider (Tinfoil's counterpart is), so
  it is the default and Tinfoil's is its private counterpart. The policy trade is
  **policy-based privacy (GreenPT) vs TEE (Tinfoil)** — say so plainly rather than
  implying GreenPT is confidential computing.
- `greenpt/glm-5.3` is the strongest **agentic** model in the green tier (1M context).
- Note the **dotted slug** `glm-5.3-flash` on GreenPT, distinct from Tinfoil's
  `glm-5-3-flash` (hyphenated). Getting a model slug wrong is a silent 404 at call
  time.

## Historical

- **Removed 2026-10:** `green-l` / `green-r` — GreenPT now marks them "not
  recommended".
- The config comment previously read "€0.22 in / €1.10 out" alongside the dollar
  figures — see the currency note in `README.md`; the intended FX is unverified.

## The fallback key

`GREENPT_FALLBACK_API_KEY` (agent host) is the **same value** as the gateway's
`GREENPT_API_KEY` — verified by hash comparison. It powers the steward agent's
direct-to-provider fallback during a gateway outage. **Rotating one without the
other silently breaks the fallback** (a dedicated key is the cleaner end state).
