Grok STT 1.0 deployment guide

How to choose a Grok STT 1.0 inference provider

Grok STT 1.0 is indexed here as a transcription model by xAI, with 1 provider endpoint from xAI. The comparison preserves each exact OpenRouter routing tag so pricing and performance observations can be connected to the route an application would actually request.

Match the endpoint to the workload

The model publishes a 0-token context window. It accepts audio input and returns transcription output. 10 distinct supported parameters appear across the listed routes. Confirm limits on the specific endpoint rather than assuming every host exposes the same configuration.

Compare transcription billing units directly

At least one unit is published consistently across the listed endpoints, allowing a direct price chart for prompt. Other charges remain in the table using OpenRouter’s exact billing labels.

Verify route format and availability

Published endpoint formats include unknown. Availability, rate limits, and regional support can change independently of catalog pricing, so confirm the selected routing tag before production deployment.
