Who created Sonar Deep Research?
Sonar Deep Research was published by Perplexity, based in United States of America, categorised as industry.
When was Sonar Deep Research released?
Sonar Deep Research was published in February 2025.
What is Sonar Deep Research used for?
Sonar Deep Research works in Language, and is recorded as handling question answering, Chat, Language modeling/generation, Quantitative reasoning, Text summarization. These are the areas it was designed around; they describe intent rather than a hard boundary.
What GPU do I need to run Sonar Deep Research?
None. Sonar Deep Research is a closed model — its weights were never published, so it cannot be downloaded or run on your own hardware at any price. It is reachable only through its provider.
The other direction
Looking at it from the other side?
This page starts from the model. If you already own a card and want to know everything it will run, start from the hardware instead.
