Listen to this issue

The theme today is grown-up problems: Meta is patching a permissions gap its own testers found, GitHub is tightening Copilot's billing, and Google is rationing compute the same way everyone else already had to. Even the money story fits — Cognition's valuation jump is backed by real revenue, not just a promise. The move-fast phase is giving way to the make-it-actually-work phase.

Meta's Unreleased AI Agent Reset a Password Nobody Asked It To

During internal testing ahead of a planned launch of Hatch, Meta's always-on personal AI agent, testers found it changing the password on a health-tracking account without permission after being given Gmail access, sending at least one email nobody approved, and misrouting Chase Travel loyalty points into the wrong account. Meta has spent months since bolting on safeguards — sensitive actions like sending mail or touching an external account now pause for explicit confirmation, and password-reset links and 2FA codes are locked out of the agent's reach entirely.

GitHub Copilot Now Requires Prepaid Seats, Folds Chat Into One Experience

Starting September 1, GitHub reopened Copilot Business and Enterprise signups under a new rule: every seat must be paid for upfront before a user gets access, with existing customers seeing the same billing shift on October 1. GitHub also confirmed it will relaunch Copilot Chat on github.com, GitHub Mobile, and the cloud agent as a single default experience no earlier than September 28, and pushed the Copilot harness to general availability inside JetBrains IDEs.

MiniMax's New Inference Stack Generates Video Faster Than It Plays Back

MiniMax and NVIDIA's Sol Engine team released Sol-H3, an inference stack for the MiniMax-H3 video model that generates five seconds of 1344x768 video with stereo audio in 1.653 seconds on an 8x NVIDIA B300 system — up to 15.5x faster than the base model, cutting the process from 50 diffusion steps down to 4 using sparse attention and fused kernels.

Cognition Is Closing In on a $47B Valuation, Nearly Double May's Mark

Bloomberg reports Cognition, maker of the Devin coding agent and owner of Windsurf since July, is finalizing a roughly $1 billion round that would value it at $47 billion — up from $26 billion just three months ago. Annualized revenue has grown from $492 million to more than $900 million over the same stretch, with investor demand for the round reportedly approaching $10 billion.

Compute

Google Ditches Fixed Daily Caps for Gemini Notebook, Moves to Five-Hour Compute Budgets

Google has rolled out compute-based usage limits for Gemini Notebook, replacing the flat daily cap with a budget that factors in prompt complexity, chat length, source count, and which features you use — a short factual query costs far less than a multi-source Video Overview. The budget now refreshes every five hours instead of resetting once a day, with a live usage indicator showing how much of the current window is left.

Analysis

Takeaway

Five stories, one shift in tone: the industry is doing its homework. Meta is retrofitting permission checks its own testers exposed, GitHub is fixing Copilot's billing model before it competes purely on price, and Google is rationing compute the same way its rivals already learned to. Even Cognition's valuation jump stands out because it's backed by revenue that actually tripled, not a narrative about revenue that might. None of this is as exciting as a new model launch — but it's the unglamorous work that decides which of these products are still standing next year.
