Vercel's AI Gateway plugin connects any WordPress 7.0 site to hundreds of models from 40-plus providers, including Anthropic, Google, OpenAI, xAI, and DeepSeek, through a single API key managed under Settings > Connectors.
The plugin works as a connector for the new WordPress AI Client, meaning any existing AI-powered plugin built on that client picks up multi-provider access automatically, with no separate integrations or per-provider credentials required. It supports text, structured JSON output, image generation and editing, and video through one prompt builder, with automatic fallbacks if a provider goes down and dynamic model discovery that does not require a plugin update.
The full documentation covers code-level implementation with specific examples across each modality and explains the unified billing and observability layer that tracks usage at provider prices. If you are managing AI credentials across multiple WordPress projects or building plugins that need provider flexibility without hard dependencies, the implementation details are worth reading in full.
