Overview
GPT-5 Mini vs Perplexity Sonar Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
OpenAI / GPT-5 Mini
proDescription
OpenAI's smaller, faster GPT-5 model is built for well-defined tasks at low cost. GPT-5 Mini handles coding, writing, and analysis with the same reasoning-effort control as its larger siblings, at a fraction of the price. It reads text and images across a 400,000-token context. Its knowledge is dated, and OpenAI now points to newer models, but it remains a capable, economical everyday option.
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.

OpenAI / GPT-5 Mini
proCost-Efficient Coding
Built for coding help at scale rather than the hardest engineering problems. Handles routine generation, review, and explanation reliably, and its low price makes it suited to high-frequency use inside applications.
Adjustable Reasoning Effort
Reasoning effort runs from minimal through low, medium, and high, so you trade thinking time against cost per request. Reasoning tokens are supported, so the model can work through a problem first.
Room For Long Documents
A 400,000-token context window, roughly 300,000 words. Enough for long reports, large contracts, and substantial codebases in one session, though short of the million-token frontier models.
Everyday Writing
Handles emails, summaries, documentation, and general content reliably. Aimed at clear, correct output on ordinary writing tasks rather than the polished long-form work of the flagship models.
Analysis On Dated Knowledge
Its knowledge belongs to the GPT-5 generation, with a September 2024 cutoff. That is dated, so time-sensitive work needs live sources rather than the model's own training.
Text And Image Input
Reads text and images in the same prompt, so you can send screenshots, charts, or scanned pages alongside your question. Output is text only.
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.
