Models and credits
The three assistant models in Spice++, which plans include them, and how credits measure assistant usage.
Models
| Model | Use it for | Plans |
|---|---|---|
| Luna | Everyday circuits, quickly | All plans |
| Sol | Multi-stage designs, stability and repairs | Student, Standard, Max |
| Sol 6.1 | The hardest designs | Max |
You can choose a default model in Settings. Models your plan does not include are shown with the plan that unlocks them.
Credits
Credits measure assistant usage. One credit is a tenth of a cent of model cost, and stronger models use more per request. Your remaining credits are in the account menu and on the settings page.
Credits renew each billing period, or each month on the free plan, and do not roll over. When they run out the assistant pauses; the simulator keeps working.
