Gemini 3.1 Pro vs Perplexity Sonar Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
Google / Gemini 3.1 Pro
maxDescription
Google's most advanced reasoning model, and the widest-ranging on input. Gemini 3.1 Pro reads text, images, audio, video, PDFs, and entire code repositories inside a very large context window. Built for agentic work, advanced coding, and long-context analysis. It is still a preview release, and its output ceiling is lower than most frontier models, so very long generation needs splitting up.
Perplexity / Perplexity Sonar
proDescription
Perplexity’s search model is the only one that runs a web search on every single request. Sonar is built to answer questions with citations, not to reason or write code. It formulates the query, retrieves sources, evaluates them, and synthesizes a cited answer in one pass. Fast, cheap, and factual. A specialist rather than a general-purpose model, and it should be judged as one.

Why Use Gemini 3.1 Pro and Perplexity Sonar?
Aymo gives you more than access to individual models—it provides a complete multi-model AI workspace designed for productivity.
Google / Gemini 3.1 Pro
maxAdvanced Agentic Coding
Google names agentic work, advanced coding, and algorithmic development as core strengths. Handles multi-step tool use and cross-file reasoning, and can execute code as part of its answer.
Adjustable Thinking Depth
Thinking runs at low, medium, or high, so you set how hard the model works before it answers. Google recommends leaving temperature at its default to protect complex reasoning.
Room For Repositories
A very large context window. Google states it takes on whole code repositories, research corpora, and PDF sets in one pass, without chunking the input into separate requests.
A Lower Output Ceiling
Its single-response output ceiling is roughly half that of most frontier models. Fine for reports and documentation, but book-length or full-codebase generation needs breaking into parts.
Search Grounding Built In
Its knowledge is dated by current standards. Google's own guidance is to use the Search Grounding tool for anything more recent, which the model supports natively.
Reads Video And Audio
The broadest input range available. Text, images, audio, video, PDFs, and code, handled natively. Video and audio input are rare, and no other model here accepts both.
Perplexity / Perplexity Sonar
proNot Built for Coding
Sonar is a search-to-answer system, not a coding model. It will answer questions about code by finding documentation and discussion, but it is not intended for writing, refactoring, or debugging software.
Retrieval Over Reasoning
Perplexity positions Sonar as lightweight and fast, aimed at straightforward queries rather than multi-step deliberation. Its heavier siblings handle chain-of-thought reasoning. This one is tuned for speed and factual accuracy.
Search Depth You Control
Search context size can be set to low, medium, or high, controlling how much of the web is retrieved before answering. Results can be filtered by domain and by recency, from the past hour to the past year.
Cited Answers Writing
Every response carries inline citations pointing to its sources. That makes it strong for research summaries and fact-checking, and weak for creative or long-form writing, which is not what it was built for.
Live Web Search on Every Request
Sonar has no static knowledge ceiling because it searches before answering, every time. Perplexity reports it outperforms non-grounded models on factual question answering for exactly this reason.
Text and PDFs
Accepts text and PDF files, and can answer questions about a PDF's contents. It does not accept images, audio, or video as input.
