You can now access OpenAI's latest open source model, GPT-OSS-Safeguard-20B using Vercel's AI Gateway with no other provider accounts required.

GPT-OSS-Safeguard-20B is a fine-tuned version of its general-purpose GPT-OSS model, designed for developers to implement custom, policy-driven content moderation.

AI Gateway lets you call the model with a consistent unified API and just a single string update, track usage and cost, and configure performance optimizations, retries, and failover for higher than provider-average uptime.

To use it with the AI SDK, set the model to openai/gpt-oss-safeguard-20b:

import { streamText } from 'ai'
const result = streamText({
  model: "openai/gpt-oss-safeguard-20b",
  prompt: "Why are safety classification models important?"
})

Includes built-in observability, Bring Your Own Key support, and intelligent provider routing with automatic retries.
