OpenAI Guardrails

OpenAI powers some of the most advanced language models in the world, including GPT-4, o3, Whisper, and DALL·E. These models are widely used for building applications across chat, summarization, code generation, document understanding, transcription, and multimodal tasks. But running them in production requires more than just model performance—it demands safety, compliance, and control.

Portkey acts as a powerful gateway layer for OpenAI, allowing you to apply customizable guardrails to every request without changing your application code. Whether you're concerned about prompt injection, data redaction, output filtering, or governance, Portkey provides a seamless way to manage and secure AI usage at scale.

With Portkey, you can:

Protect your AI stack from security threats with built-in guardrails
Route requests with precision and zero latency based on guardrail checks
View guardrails verdicts, latency, and pass/fail status for every check in real time.
Enforce org-wide AI safety policies across all your teams, workspaces and models.
Integrate existing guardrail infrastructure through simple webhook calls
Secure vector embedding requests

Portkey supports all Bedrock models out of the box and can be deployed in hours, not weeks, making it the easiest way to bring enterprise-grade control to your AI stack.

World-Class Guardrail Partners

Integrate top guardrail platforms with Portkey to run your custom policies seamlessly — from content filtering and PII detection to moderation and compliance. Ensure every AI request is safe, auditable, and aligned with your enterprise standards.
