Models and cost
Choose a model and keep cost predictable
resolvenengine runs on your own AI API key, so you choose the model per task and pay your provider directly at their rate, with per-run cost ceilings and a visible token and duration summary on every answer.
Last updated 18 September 2026
Why bring your own key
- No resale margin on tokens: you pay the provider's own price.
- A stronger model can be cheaper here than a weaker model behind a reseller.
- You can switch models without changing tools.
- Your key stays server-side and never ships inside the extension.
Pro is $19 USD per month and requires your own supported AI API key; the AI provider bills usage separately.
Picking a model per task
| Task | What matters | Choose |
|---|---|---|
| Summarizing a page or inbox | Speed and cost | A fast mid-tier model |
| Multi-step research | Planning and follow-through | A strong reasoning model |
| Form filling and page work | Precision on structure | A strong model, short runs |
| Long documents | Context window | A model with a large context |
Cost controls that actually bite
- Per-run ceilings stop a task instead of grinding through your budget.
- Stagnation and dead-end detection ends loops early.
- A research ledger avoids re-reading pages that added nothing new.
- Each answer shows steps, duration and tokens in and out, so you can see what a workflow costs before you repeat it.
