Unisound Rate Limits

Unisound Token Hub enforces per-model RPM (requests per minute) and TPM (tokens per minute, input + output combined) limits; the API refuses further requests when a threshold is exceeded within the window. No rate-limit response headers are documented. On the legacy AI Open Platform, error code 20206 signals concurrency limit exceeded and 20207 quota exhausted.

Unisound Rate Limits is the machine-readable rate-limit profile for Unisound on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 9 rate-limit definitions, measuring requests_per_minute and tokens_per_minute.

Tagged areas include Rate Limiting and Artificial Intelligence.
