One OpenAI-compatible endpoint for OpenAI, Claude and Gemini models
Send requests in the familiar chat-completions format to a single base URL, so existing OpenAI SDKs and wrappers work with minimal edits.
Reach OpenAI, Claude and Gemini models from the same credentials instead of juggling three separate accounts and billing setups.
Swapping providers usually means changing a base URL and a model name rather than rewriting application code.
Choose the model that best fits a task's price and quality needs, helping keep inference spend under control.
Real-time AI answer engine and research workspace combining live web citations with frontier reasoning models.
Executes multi-step iterative web and document research across hundreds of sources, cross-checking facts and generating structured, citation-backed analytical reports that can be exported as PDFs or shared as interactive Perplexity Pages.
Lets Pro and Max subscribers switch dynamically between Perplexity's in-house Sonar models and top external models (including Claude 4, o3-pro, and Gemini) or compare multi-model reasoning outputs side by side.
Provides dedicated project workspaces where users upload local PDFs, spreadsheets, and text files, configure custom assistant instructions, and run queries that combine private document retrieval with live internet search.
Extends Perplexity from passive Q&A into agentic execution, turning high-level user requests into completed workflows, multi-tab browser actions, and automated data synthesis via the Comet ecosystem.
Offers deeper conversational reasoning and coding agents, but lacks Perplexity's dedicated inline citation-first search layout.
