Collection notes
Text to speech: only the pay-as-you-go plan is modelled: the page prices text to speech per 1,000 characters for three models and the Aura-2 rate is recorded (Aura-1 is half of it, Flux TTS 1.5 times). The Growth plan is an annual prepaid commitment starting at $4,000 a year and Enterprise is custom; neither is a monthly price. The $200 sign-up credit is a one-time credit, not a monthly allowance. The MCP server is part of the Deepgram CLI and runs locally. Speech to text: the Pay As You Go Nova-3 Monolingual rates are the two plans, pre-recorded and streaming; Nova-3 Multilingual ($0.0052 a minute pre-recorded), the Growth plan (prepaid yearly credits from $4,000 a year, Nova-3 Monolingual $0.0036 a minute pre-recorded) and Enterprise are not modelled. Rates are per audio minute on the page; the plans carry them per audio hour (x 60).
