Practical guides on AI security, LLM pricing, PII redaction, and building with AI safely.
How Semantic Caching Cuts LLM API Costs by 15-40% Without Code Changes
Your AI application is paying full price for prompts it has already answered. Semantic caching at the gateway layer eliminates redundant LLM calls with zero cost, sub-millisecond latency, and no SDK changes.
How to Redact Social Security Numbers from OpenAI API Calls (Python)
Step-by-step Python guide to automatically detect and redact SSNs, credit card numbers, and other PII before sending prompts to the OpenAI API. Three approaches: regex, Presidio NLP, and gateway-level redaction.
EU AI Act Article 12 Logging Requirements for ChatGPT API (2026 Compliance Guide)
If you use the ChatGPT API in a high-risk EU application, Article 12 requires automatic event logging by August 2, 2026. Here's what you must log, what format to use, and how to implement it.
EU AI Act Article 12: What AI Teams Need to Log Before August 2026
The EU AI Act's Article 12 requires automatic event recording for high-risk AI systems. Enforcement begins August 2, 2026. Here's exactly what you need to log and how to be compliant in 10 minutes.
AI Agent Infinite Loop Protection: Stop Runaway LangChain and CrewAI Costs at the Gateway Layer
AI agents get stuck in infinite retry loops more often than you think. Fingerprint-based loop detection at the gateway layer catches and kills runaway LangChain, CrewAI, and AutoGPT loops in real time — before they drain $108/hour.
Stop Discovering AI Security Incidents in Log Reviews: Real-Time Webhook Alerts for Every PII Leak and Injection Attack
Most AI proxies require you to poll for security events. AISG pushes them. HMAC-signed webhook alerts for PII blocks, prompt injections, budget exhaustion, and agent loops — delivered to Slack, PagerDuty, or any SIEM endpoint in real time.
LiteLLM SQL Injection (CVE-2026-42208): Why AI Gateways Must Be Fail-Closed
The LiteLLM SQL injection vulnerability was exploited in 36 hours. Here's why AI gateways are Tier-0 secrets stores, what fail-closed architecture means, and what to look for before the next CVE lands.
Palo Alto Acquired Portkey. Here's What Portkey Can't Do.
Palo Alto Networks is buying Portkey for the routing half of AI governance. But routing without DLP is a highway without guardrails. Here's the governance gap Portkey leaves open — and why it matters.
GPT-5.5 API: Getting Started with PII Protection
GPT-5.5 just launched. Here's how to call it via the OpenAI API, why its expanded reasoning and agentic capabilities create new PII exposure risks, and how to add automatic data protection in two lines of code.
OpenAI Privacy Filter vs. a Security Gateway: Why a Model Isn't a Product
OpenAI released Privacy Filter — an open-weight PII detection model. But a model that finds PII in text is not the same as a system that enforces data policy across every provider. Here's the difference.
LLM Token Budget Strategies for Agents: Stop Runaway Costs Before They Start
Autonomous AI agents can burn through your LLM budget in minutes. Here are 5 practical token budget strategies — from per-request ceilings to circuit breakers — that keep agents productive without bankrupting your team.
OpenRouter 403 Error, Rate Limits & Why Teams Switch: Alternatives for 2026
Getting 403 Forbidden errors on OpenRouter? You're not alone. Here's why it happens, what OpenRouter doesn't tell you, and the best OpenRouter alternatives for enterprise teams, Janitor AI users, and anyone who needs reliability.
Vercel AI Gateway vs the Alternatives: Honest Comparison for 2026
Vercel AI Gateway is convenient but limited. Compare its features, pricing, zero-data-retention guarantees, and governance gaps against open source and self-hostable alternatives.
Prompt-Level PII Redaction at the Gateway Layer (Under 50ms, No Code Changes)
How to implement prompt-level data loss prevention and PII redaction at the LLM gateway layer without introducing unacceptable latency for real-time use cases. A working architecture that hits 30-50ms text and 150ms vision.
What Is an OpenAI Compatible API Proxy? (And Why You Probably Need One)
An OpenAI compatible API proxy lets you call Anthropic, Groq, Gemini, Mistral, and 600+ models using the OpenAI SDK with no code rewrite. Here's how it works, why teams use one, and how to build production-ready integrations in 2 lines of code.
How to Prevent PII Leaks in ChatGPT API Calls
Every ChatGPT API call is a potential PII leak. Learn the 3 approaches to stop sensitive data from reaching AI providers — and how to implement automatic redaction in under 5 minutes.
