OpenAI Users Can Cap API Spend at $100 in Tier 1, Add 429 Hard Stops

Summary
$100 a month is the default ceiling for OpenAI Tier 1 accounts, but ZDNET says users should still set explicit spend caps, alerts and rate limits to avoid runaway agent bills.
At $50 in cumulative API spending, accounts move to Tier 2 with a $500 monthly allowance; after $1,000 total spend, OpenAI can permit up to $200,000 a month.
A hard limit can be enforced from the Limits page, causing API calls to fail with 429 errors once the cap is hit instead of letting actual costs exceed the budget.
Spend alerts can email users when usage hits a chosen percentage of budget, while auto-recharge settings control how much prepaid credit is added automatically.
Rate limits add a second safeguard by capping requests and tokens per minute or day, and OpenAI recommends exponential backoff so apps handle throttling cleanly.
