A paid plan's credits are dollars of usage equal to the plan fee, deducted at the tier rate, so the characters a plan covers depend on the model. They are entered at the rate of the TTS-2 model (the dearer of the two); the Flash model covers more for the same credits. Overage is charged at the same rate as the plan. The 70 free minutes of On-Demand are counted at about 1,000 characters a minute, as the page does. The MCP server ships in the Inworld CLI and runs locally. ## Sources and notes Each number points to the provider's own sentence, as it appears on the page on the date shown. 1.
