The rise of AI-powered research tools has taken a significant step forward with Perplexity’s latest offering, which aims to automate complex research tasks typically performed by human analysts. Perplexity’s Deep Research feature represents a notable advancement in AI-assisted information gathering and analysis, combining multiple searches with sophisticated source evaluation.

Product Overview: Deep Research is a new AI feature that conducts comprehensive research by performing dozens of searches and analyzing hundreds of sources to create structured reports within minutes.

  • The system mimics human research methodology by iteratively refining its understanding of topics and systematically searching for relevant information
  • Users can apply Deep Research across various domains including finance, marketing, technology, health, current affairs, and travel planning
  • The tool demonstrates significant accuracy, achieving a 21.1% score on Humanity’s Last Exam benchmark

Technical Capabilities: Deep Research employs an advanced approach to information processing that sets it apart from traditional search engines.

  • The system conducts multiple searches simultaneously, creating a more comprehensive view of any given topic
  • It synthesizes information from numerous sources, evaluating and cross-referencing data to ensure accuracy
  • The technology demonstrates the ability to understand context and maintain coherence across complex topics

Accessibility and Platform Support: Perplexity has implemented a tiered access model while planning broader platform availability.

  • The feature is currently free for all users, though daily query limits apply for non-subscribers
  • Pro subscribers receive unlimited access to Deep Research queries
  • While initially available on web browsers, the company plans to expand to iOS, Android, and Mac platforms

User Implementation: Deep Research can be accessed through a straightforward process on the Perplexity platform.

  • Users can find the feature by visiting perplexity.ai
  • The tool is activated by selecting Deep Research from the mode menu before submitting queries
  • Results are delivered in structured report formats that organize findings systematically

Looking Beyond Initial Implementation: The introduction of Deep Research signals a shift in how AI tools are being deployed for knowledge work, though questions remain about its impact on traditional research methodologies and the potential need for human verification of AI-generated findings.

DOE fusion roadmap targets 2030s commercial deployment as AI drives $9B investment

The Department of Energy has released a new roadmap targeting commercial-scale fusion power deployment by the mid-2030s, though the plan lacks specific funding commitments and relies on scientific breakthroughs that have eluded researchers for decades. The strategy emphasizes public-private partnerships and positions AI as both a research tool and motivation for developing fusion energy to meet data centers' growing electricity demands. The big picture: The DOE's roadmap aims to "deliver the public infrastructure that supports the fusion private sector scale up in the 2030s," but acknowledges it cannot commit to specific funding levels and remains subject to Congressional appropriations.
