Good morning, AI enthusiasts. ChatGPT just learned a new trick — working the night shift while you sleep to craft personalized briefings ready when your alarm goes off.

OPENAI

🗞️ ChatGPT gets proactive with new Pulse briefs

The Rundown: OpenAI just launched ChatGPT Pulse, a new preview feature that proactively generates personalized morning briefings while users sleep, initially available exclusively for Pro ($200/mo) subscribers.

The details:

The feature automatically creates 5-10 cards overnight based on chat history, user feedback, or connected Gmail and Google Calendar data.
Users can shape future briefings through direct requests or thumbs-based feedback, with updates refreshing daily unless specifically saved.
OpenAI said it deliberately designed Pulse to stop after several reports, displaying "that's it for today" to avoid engagement-driven scrolling patterns.
Pulse will eventually also roll out to Plus subscribers, becoming the first of several “compute-intensive” new features set to be trialed with the Pro tier.

Why it matters: OpenAI’s personalization movement has been in the works for a while, but this feels like a new step forward — with pulse rolling many of the platform’s top traits like productivity, news, connectors, and life insights unique to each user into a curated morning roundup built for the proactive, agentic era of AI assistants.

ELON MUSK

🏛️ Elon Musk, xAI sue OpenAI over trade secrets

The Rundown: xAI just filed a new lawsuit accusing OpenAI of systematically poaching employees to steal trade secrets, the latest legal move in the ongoing contentious battle between Elon Musk and his former company.

The details:

xAI named 8 former employees allegedly recruited via a coordinated effort, including several who admitted copying source code to personal devices.
Two engineers allegedly downloaded xAI's codebase while communicating with the same OpenAI recruiter through encrypted messaging app Signal.
Court filings also show a senior finance executive, who knew xAI's data center operations were its "secret sauce," refuse to comply with legal warnings.
OpenAI dismissed it as the “latest chapter in Musk’s ongoing harassment,” with previous actions against OAI’s restructure, mission, and antitrust allegations.

Why it matters: If you like drama, Elon vs. OpenAI is the gift that keeps on giving. But the lawsuit also exposes the darker side of the AI talent wars and flurry of movement between labs this summer, where proprietary breakthroughs are now just a job change away from potentially heading to the competition.

AI RESEARCH

💼 OpenAI tests AI against human workers across 44 jobs

The Rundown: OpenAI just introduced GDPval, a new benchmark that measures whether AI models can match professional work quality across 44 occupations — testing top models like GPT-5, Claude Opus 4.1, Gemini 2.5, and Grok 4 against industry experts.

The details:

GDPval evaluated 1,320 tasks created by professionals averaging 14 years of experience across 9 economic sectors like healthcare and finance.
Opus 4.1 achieved the highest scores with a 47.6% win rate and excelled at visual presentation tasks, while GPT-5 led in technical accuracy.
OpenAI also found that performance tripled from GPT-4o to GPT-5 over 15 months, showing rapid improvement in workplace task capabilities.

Why it matters: Despite the headlines of immediate workforce replacement, GDPval shows even the best models are just reaching parity with professionals on certain tasks. But if this benchmark is anything like others in the AI world, its not long before more advanced models make a significant jump with just a few months of acceleration.
