Pricing
You pay for input tokens only. Output is free. Every new account gets $2 of free credit, about 66 million input tokens.
| Model | Input | Output |
|---|---|---|
Simo-1 Pro (simo-1-pro) |
$0.03 per 1M tokens | Free |
The console always shows the current rates under Billing.
What that means
Reading the situation is the cost; questions about it are nearly free. So ask everything you need about one input in one request.
| Request | Input tokens | Cost |
|---|---|---|
| A support ticket with 4 questions | ~250 | ~$0.0000075 |
| A one-page contract with 10 questions | ~1,500 | ~$0.000045 |
| A million short tickets | ~250M | ~$7.50 |
Images count by the tokens the model reads from them, so large screenshots cost more than a paragraph of text.
What you are not charged for
- Requests refused before they run: a bad key, an empty balance, an invalid request.
- Failures on our side (502, 503, 504) and rate-limited requests (429). The SDK retries these automatically.

Accounts are prepaid. Every new account gets $2 of free credit when its email is confirmed (straight away when you sign up with Google). Requests are refused with 402 insufficient_balance once the balance reaches $0. To add more, contact us from the console's Billing page.
