Pricing
Pricing is based on actual usage, with charges varying according to how much you consume. Subscriptions have no end date and may be canceled any time.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.
Dimension | Description | Cost |
|---|---|---|
ml.m5.large Inference (Batch) Recommended | Model inference on the ml.m5.large instance type, batch mode | $0.00/host/hour |
inference.count.m.i.c Inference Pricing | inference.count.m.i.c Inference Pricing | $0.006/request |
Dimensions summary
This listing bills on usage, with two separate dimensions. You pay per hour for model inference running on the ml.m5.large instance in batch mode, charged by host hours. You also pay per inference request under the request-based dimension. The two charges work independently: one covers the compute time the model runs, the other counts the number of inference calls you make. Costs rise as you add host hours or make more requests. There are no upfront commitments or fixed tiers here; your total scales directly with how much you run and call.
Top-of-mind questions for buyers
A request is one call to the text-to-speech model. Each session can run up to 300 seconds, so longer text should be split into separate sessions. You pay per request you submit, regardless of audio length within that session limit.
The two charges bill independently and both appear together. The host-hour charge meters time the ml.m5.large instance runs in batch mode. The per-request charge counts each inference call. Host hours drive cost for long-running compute; request volume drives cost when you make many calls.
The host-hour charge meters time the instance runs in batch mode. When the instance is stopped, software host-hour charges stop too. Underlying AWS storage or related fees may still apply separately. The per-request charge applies only when you submit inference calls.
