## Summary  
The paper investigates how autonomous AI agents transform knowledge work by comparing two products, Search and Computer, using production data from Perplexity. It finds that agents dramatically increase autonomy, efficiency, and the scope of tasks performed. These findings reveal shifts in query patterns, quality improvements, and cost reductions. Overall, AI agents reshape workflows by automating decomposition, lowering time/cost, and enabling higher‑order, cross‑functional work.

## Key Contributions  
- [Finding 1] Autonomous agents execute tasks end to end, delegating task decomposition and execution, leading to 26 minutes of autonomous work per session versus 33 seconds for Search; dissatisfaction rates drop 55%.  
- [Finding 2] Autonomy reduces completion time from 269 to 36 minutes on matched tasks, cutting estimated time by 87% and cost by 94% compared with human‑only Search.  
- [Finding 3] Agents expand the scope of work: they generate cross‑occupational queries, higher‑order cognition, composite tasks, unlocking activities absent from Search.  

## Methodology  
The authors leveraged production usage logs from Perplexity’s Search and Computer products as a natural experiment. They paired near‑identical initial query pairs across both systems to isolate the effect of autonomy. By tracking session length, user satisfaction (dissatisfaction rates), task complexity, and query diversity, they quantified changes in time, cost, and scope.  

## Results  
First finding: per‑query dissatisfaction is 55% lower on Computer than Search, indicating higher quality output. Second, autonomous sessions cut completion time by 87% and estimated cost by 94%. Third, Computer generates more cross‑occupational queries, uses broader expertise, and creates composite tasks, expanding the scope of automated work.  

## Significance  
These results demonstrate that autonomy is a lever for accelerating knowledge work, improving output quality, and reducing resource consumption. By enabling agents to handle decomposition and execution without human orchestration, AI can lower operational costs and unlock previously unattainable task combinations. The findings have implications for designing next‑generation assistants that prioritize end‑to‑end agency over conversational support.
