The wiki
A field guide to the people, organizations, and ideas in our reporting.
Phind
An AI search company that evolved from answering programmers’ questions to generating interactive answers and custom mini-apps.
Phind’s path from retrieved answers to coding models
Better context and stronger models turned a search product into a coding assistant. Specialized training promised more control over cost and capability; consistent correctness remained the harder problem.
Phlo Young
AI workshop presenter whose teaching spans generative music, creative control, and local exploration of training datasets.
Physical AI Has to Survive the Machine
Applied Intuition connects autonomy models to the engineering that makes them usable: sensor supervision, reliable operating systems, validated simulation and inference that fits the machine.
Pixee
An application-security company combining AI agents and deterministic code transformations to triage scanner findings and deliver fixes through developer workflows.
Playground’s Bet: Build the Model and the Graphics Editor Together
Better images are only part of the problem. Playground’s ambition connects model quality, precise editing, visual control, and feedback from people making things.
Pliny the Liberator
Pseudonymous AI jailbreak researcher who publishes prompt techniques and argues for transparency, capability exploration, and harm reduction outside the model.
Poolside
An AI foundation-model company built around coding, execution feedback and an integrated Model Factory, with a consequential NVIDIA licensing deal reported in August 2026.
Poolside AI
A foundation-model company pursuing software intelligence through code execution feedback, an integrated Model Factory, and the Laguna family of agentic models.
Portkey.ai
An AI gateway company that expanded from LLM operations into governance and agent infrastructure, acquired by Palo Alto Networks in May 2026.
Post-Training’s Moving Bottlenecks: Rewards, Tokens, and Systems
Josh McGrath on the engineering behind reinforcement learning, efficient agents, and useful long context, in a conversation at NeurIPS 2025.
Post-Transformer Architectures in 2024: Cheaper Sequences, Finite Memory
Linear attention, state-space models and RWKV reduce the cost of processing sequences. Their harder challenge is preserving the information a task needs—and making that computation fast on real hardware.
Practical AI
An AI podcast hosted by Daniel Whitenack and Chris Benson, launched with Changelog in 2018 to make AI practical, productive, and accessible.
Practical fine-tuning with Axolotl
From incompatible datasets to efficient training: how Axolotl turns model-building experience into reusable configuration.
Pranav Reddy
Conviction partner and former Neeva engineer whose writing examines AI business durability, search infrastructure and enterprise automation.
Pratik Bhavsar
Creator of Galileo’s Agent Leaderboard, focused on evaluating whether AI agents complete tasks and turning failures into verifiable improvements.
Pratyush Maini
Machine-learning researcher and DatologyAI founding member studying how training data shapes foundation-model capabilities, memorization, and safety.

Prime Intellect builds open models and infrastructure for improving them, spanning distributed compute, reinforcement learning, executable environments, and agent tooling.
Princeton
Princeton University's AI work spans software-engineering benchmarks, deep reinforcement learning, agent reliability, and an expanding institutional structure for AI and data science.
Priscilla Chan
Pediatrician and philanthropic co-founder whose work connects AI-powered biological research with the goal of improving patients’ lives.
Production AI Engineering Starts with Evals
Braintrust connects production logs, comparative evaluation, and interactive debugging so teams can improve AI behavior—and decide which work belongs in ordinary code.
