Perplexity's Teammates, Notion's Agent Bet, and the Vibe Coding Origin Story
Perplexity shipped internal numbers showing employees are getting 7x more agent-hours per week since September, Notion keeps rebuilding its AI stack around a credit system and model router instead of flat seats, and Amjad Masad's origin story for vibe coding is a reminder that the biggest product insights sometimes come from just watching what users paste into a text box.

Perplexity - Teammates Launches, and Aravind Srinivas Shares the Adoption Numbers Perplexity launched Teammates, a set of work-focused AI agents, on November 5. Within a day, CEO Aravind Srinivas followed up with two separate data points: the Agent API's benchmark score climbed from 55% to 77% while cost dropped nearly 90% month over month, and internally, "the median Perplexity employee now gets 7x more agent-hours per week from teammates than in September." |

Notion - Rebuilt Its AI Pricing Around Credits, Not Seats Notion shipped a reworked AI system: smarter model routing, long-running agents, a bring-your-own-AI option, and a new credit-based system replacing flat per-seat AI pricing. Co-founder Akshay Kothari frames it as "agents, rebuilt to do more for less." |

Amjad Masad - The Origin Story of Vibe Coding In a wide-ranging interview with Paul Graham, Replit CEO Amjad Masad described how vibe coding emerged: Replit noticed users were pasting ChatGPT-generated code directly into the IDE, which led the team to build an AI agent that closed that gap directly inside the product. Separately, Masad posted on X that "Replit is the only collaborative AI coding system out there," responding to a request for team features in Claude Code. |
