About

OpenAI's deep research is an AI-powered tool designed to autonomously conduct complex, multi-step research tasks across various domains, such as science, coding, and mathematics. By analyzing user-provided inputs—such as questions, text documents, images, PDFs, or spreadsheets—the system formulates a structured research plan, gathers relevant information, and delivers comprehensive responses within minutes. It also provides process summaries with citations, helping users verify sources. While this tool significantly accelerates research efficiency, it may occasionally produce inaccuracies or struggle to differentiate between authoritative sources and misinformation. Currently available to ChatGPT Pro users, deep research represents a step toward AI-driven knowledge discovery, with ongoing improvements planned for accuracy and response time.

About

Sakana Marlin is your Virtual CSO for Ultra Deep Research, built so AI handles research and humans focus on decision-making. It is not just another deep research assistant; it is an autonomous agent designed to take on the kind of substantial strategy research that a Chief Strategy Officer and a small team might otherwise spend weeks on. Powered by Sakana AI’s core reasoning architecture, Sakana Marlin scales inference-time compute to execute up to eight hours of continuous, autonomous reasoning. Once a research topic is set, it works without further human input, repeatedly forming hypotheses, gathering information, navigating the web, and resolving contradictions on its own. Instead of generating text in seconds, its focus is long-horizon, sample-efficient reasoning that cycles through hypothesis testing and web research to extract what truly matters from vast amounts of information. Sakana Marlin does more than summarize.
