The fees are the same number in US dollars ($135 and $485), and £115 and £415, or CHF 125 and CHF 450. Growth starts with a 14-day free trial. On paid plans, your requests are served before Free accounts' requests when Strom is busy. Switching between paid plans applies at once: the rest of the billing period is charged or credited. Moving to Free takes effect at the end of the period you paid for.
Spend cap
Set a monthly spend cap under Billing. A request that would take this month's spend past the cap gets 402 until the month ends or you raise the cap. Owners get an email at 80%.
Zero data retention
20% more per 1M input tokens: $0.0504 for strom-fast, $0.288 for strom-base. Output tokens are free. On a paid plan, private requests are paid from your balance. On Free, they are paid from the ZDR credit of the zero data retention subscription: $50, €50, £50 or CHF 50 a month, plus VAT, and from ZDR top-ups, which do not expire.
Agent guard
Input tokens at the strom-fast price, plus $0.50 per 1,000 sessions past your plan's monthly sessions. A check that no rule applies to is free. See Agent guard.
Document extraction
Input tokens at the model's price. See Document extraction.
Self-improvement
Each run that improves your document extraction is charged to your balance for the AI processing it uses, at twice our provider's price. A typical run costs about €2 to €3.
Input tokens
Calculated as: state + question list + image tokens.
Images: one token per 1,024 pixels. Images over 1 megapixel are scaled down to 1 megapixel and small images are scaled up, so an image costs between 64 and 1,024 tokens.
A box question (beta) costs as much as one question plus the tokens of a copy of its image for each region it considers, at most 8. With multiple set to true, it costs one question per region instead of one in all. The images themselves are paid for once, only when other questions see them, or when a box question searches another image of the request.
Request size
Up to 256 questions, 256 options per question, 8 images of 10 MB each, and 32,000 input tokens in all.
Rate limits
Up to 512 questions in progress at once per account on strom-fast (64 on strom-base), counted over all your requests. When Strom is busy with all customers’ requests, new ones get 429 with a Retry-After header.
