Perplexity's base Sonar model pairs live web search with a compact LLM to deliver fast, citation-backed answers. It is the default model behind many Perplexity search experiences and is exposed through the Perplexity API as the cheapest Sonar option.

Sonar Pro uses a more capable model and expanded search context to answer complex questions with detailed, source-backed responses. It supports Pro Search for multi-step tool usage and is designed for research tasks that need more depth than the base Sonar model.

Sonar Reasoning Pro exposes explicit chain-of-thought reasoning to solve complex, multi-step problems with transparent intermediate steps. It is aimed at logical analysis, coding, and math tasks that require verifiable reasoning alongside live web search.

Sonar Deep Research conducts autonomous, multi-step research across many web sources and synthesizes a comprehensive, cited report. It is built for tasks that would otherwise require hours of manual investigation, such as competitive analysis and literature reviews.

Ox Alpha is a stealth AI model that appeared on OpenRouter and OpenCode on 20 August 2026. Its creator is unidentified, and OpenRouter routes requests to an anonymous third-party provider. The model accepts text, images and video, outputs text, and supports a 1,048,576-token context window with up to 131,072 tokens of output. Independent serving-layer forensics published on 22 August 2026 point to Zhipu AI's GLM-5.x infrastructure as the leading theory — a Java stack trace naming Zhipu's internal API classes, matching error-code dialects, 30/30 tokenizer alignment with GLM-5.3, and identical video-encoder behaviour to GLM-5V-Turbo. Zhipu has not confirmed this.
