Hi @modern frigate. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
Yes, Codex does have usage limits. The specific limits depend on how you are accessing Codex:
-
Codex in the API: Usage is subject to rate limits, which are determined by your usage tier. For example, for the codex-mini-latest model, rate limits are set per tier (e.g., Tier 1: 1,000 requests per minute (RPM) and 100,000 tokens per minute (TPM); higher tiers have higher limits). These limits are in place to ensure fair and reliable access to the API and automatically increase as your usage and spend increase. You can view your current limits in your account settings under the limits section. Free tier access is not supported for codex-mini-latest in the API Codex model documentation API rate limits guide.

Codex CLI: The codex-mini-latest model is optimized for use in the Codex CLI, but the same API rate limits apply if you use it outside the CLI Codex CLI limitations.
