README

AI Provider for Perplexity for the WordPress AI Client. Works as both a Composer package and a WordPress plugin.

This provider registers Perplexity with the AI Client, exposing Perplexity's Sonar models (Sonar, Sonar Pro, Sonar Reasoning, Sonar Reasoning Pro, and Sonar Deep Research) for web-grounded text generation through Perplexity's OpenAI-compatible Chat Completions API.

Requirements

• PHP 7.4+
• WordPress 6.9+ (when used as a plugin)
• The wordpress/php-ai-client SDK
• A Perplexity API key from the Perplexity API settings

How it works

Perplexity exposes an OpenAI-compatible Chat Completions API, so this provider is intentionally thin:

Because Perplexity speaks the Chat Completions format, PerplexityTextGenerationModel extends AbstractOpenAiCompatibleTextGenerationModel from the SDK and only overrides request construction.

Unlike most providers, Perplexity does not expose a model listing endpoint for its Sonar chat models, so the supported models are defined statically and availability is checked with a minimal text generation request rather than a list-models request.

Supported capabilities

• Web-grounded text generation (chat) with the Sonar model family
• Chat history / multi-turn conversations
• JSON / structured output
