Why We Built an AI Gateway in Go: Failover, PII Redaction, and Sub-Millisecond Caching

说明与用途

SentinelGateway 是一个基于 Go 的代理，提供故障转移、实时 PII 清理和语义缓存，降低生产 LLM 部署中的停机、合规风险和令牌成本。

问题

Teams deploying LLMs face upstream downtime, compliance data leaks, and runaway token costs.

结果

Teams using SentinelGateway experienced reduced application crashes from provider outages, eliminated GDPR/SOC2 data leakage risks, and cut token costs by caching repeated prompts.

工作流

• 1. Install SentinelGateway and set base_url to https://sentinelgateway.ai/v1 in the OpenAI client.
• 2. Configure primary and secondary providers in SentinelGateway’s Redis-backed health monitor.
• 3. Enable PII scrubbing by default; the gateway scans and redacts SSNs, credit cards, emails, and API keys before sending to upstream.
• 4. Activate semantic caching; SentinelGateway hashes prompts and checks Redis for cache hits, returning cached responses in <15 ms.
• 5. Deploy the gateway behind your application; it handles failover automatically when a provider returns 429 or 503.
• 6. Monitor usage and quotas via SentinelGateway’s Lua scripts that atomically decrement counters across nodes.

证据

SentinelGateway implements the complete /v1/chat/completions schema.

High-speed token scanners detect SSNs, credit card numbers, API keys, and email addresses.

来源

Cache hits return in sub-15ms with zero upstream token consumption.
