Model Pipeline - Rate limiting and abuse prevention
This pipeline helps protect AI services by limiting how often users can make requests. It stops too many requests in a short time, preventing abuse and keeping the system fair and stable.

Rate limiting and abuse prevention in Prompt Engineering / GenAI - Model Pipeline Trace
Data Flow - 5 Stages
1Incoming Requests
1000 requests per minute→Receive user requests to the AI service→1000 requests per minute
User A sends 100 requests, User B sends 900 requests
↓
2Request Counting
1000 requests per minute→Count requests per user in a time window→User request counts per minute
User A: 100 requests, User B: 900 requests
↓
3Rate Limit Check
User request counts per minute→Compare counts to allowed limit (e.g., 200 requests/min)→Allowed and blocked requests
User A allowed (100 < 200), User B blocked (900 > 200)
↓
4Abuse Detection
Allowed and blocked requests→Detect suspicious patterns like bursts or repeated failures→Flagged users for abuse prevention
User B flagged for excessive requests
↓
5Response Handling
Allowed and blocked requests→Send responses or error messages for blocked requests→Responses sent to users
User A gets AI answers, User B gets 'Rate limit exceeded' message

Key Insight
Rate limiting combined with abuse detection helps keep AI services fair and stable by stopping too many requests and spotting suspicious behavior early.
