GPT-5.6 Terra vs Perplexity Sonar Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
OpenAI / GPT-5.6 Terra
maxDescription
OpenAI's balanced everyday model in the GPT-5.6 family, and its new default GPT for most work. Terra delivers roughly the quality of the previous flagship at about half the cost, with strong coding, agentic work, and design sense. It reads text and images across a very large context, supports live web search, and lets you set reasoning effort per request.
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 GPT-5.6 Terra and Perplexity Sonar?
Aymo gives you more than access to individual models—it provides a complete multi-model AI workspace designed for productivity.
OpenAI / GPT-5.6 Terra
maxCoding With Design Sense
OpenAI tuned this generation for front-end taste, producing tasteful, functional interfaces from high-level direction. It can inspect the rendered result and refine it, rather than emitting code and hoping it works.
Reasoning Effort You Set
Reasoning effort runs from none through low, medium, high, and higher settings, so you control how hard the model works per request. OpenAI positions Terra as the balanced baseline for most API work.
Room For Whole Projects
A very large context window, big enough to hold a substantial project in view so the model stops losing track of files across a long build. Prompts above a high threshold are billed at a higher rate.
Professional Knowledge Work
OpenAI positions the family for professional knowledge work, science, and design alongside coding. Terra suits that work at a cost that makes running it at volume practical rather than reserved for the hardest tasks.
Web Search And Recent Knowledge
Supports web search as a tool, and its knowledge is among the most recent in the catalog. Together those cover current questions well, with the search filling anything past the training cutoff.
Text And Image Input
Reads text and images in the same prompt, so you can send screenshots, diagrams, or scanned pages alongside your question. Output is text only. Audio and video are not accepted.
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.
