But on OpenAI there's no where to increase my rate limit

To increase your OpenAI rate limit, you need to upgrade your API tier to Tier 2 or higher. Check your current usage tier at OpenAI's usage limits page.For reliable use with Clay, you need 30,000 TPM for ChatGPT columns and 450,000 TPM for Claygent. To upgrade to Tier 2, contact OpenAI's support team and ensure you have the minimum required balance in your OpenAI account.You can find more information about usage tiers at OpenAI's documentation.
