Cleanlab Rate Limits

Cleanlab applies per-account rate limits to its hosted APIs - the Trustworthy Language Model (TLM), Codex validation, and Cleanlab Studio inference. TLM enforces concurrency and request-rate limits that vary by tier (free vs. paid). The Python clients retry transient errors and respect rate limiting. Specific per-tier numeric limits are not consistently published and are not reconciled in this artifact.

Cleanlab Rate Limits is the machine-readable rate-limit profile for Cleanlab on the APIs.io network, in the API Commons Rate Limits shape.

It captures 4 rate-limit definitions, measuring concurrent_requests and requests.

An exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include AI, LLM, Trustworthiness, Data Quality, and Guardrails.

Policies

Tiered Limits
Limits raise as accounts move from free to paid usage and via Enterprise agreements.
Backoff Strategy
Clients should implement exponential backoff with jitter and honor Retry-After; the official Python clients retry transient errors automatically.
