人間（防衛側）が負けますね。攻撃側は1個所を突破すれば勝利で無限回アタックができて、防御側は1個所でも突破されたら負けで、全件証明と全件承認・確認が必要なので⋯構造が非対称の攻防戦で、無限リソースと無限時間が使える場合、ガード不可と考えてシステム設計すべきかと

Grok foundation model V9-Medium (1.5T) has finished training. Evals look good. A lot of Cursor data was added in supplementary training and there is more to come. Fine-tuning is underway and reinforcement learning begins in a few days. 2 to 3 weeks to public release. This will be a major improvement over the 0.5T v8-small that currently serves all Grok production traffic, especially for difficult coding tasks.

Tmux session running Codex on my Mac mini, custom firmware (built by Codex) on my Xteink x3. Plus a Magic Keyboard! I love e-ink!

v1リリースの最終調整のひとつとして、Mac側でサーバー起動してればアプリ起動で自動接続するようにしました！ 既存アプリが色々あるからこそ、UXにこだわったり声をすぐ取り入れられたらなと思ってます

Get a head start on your day with Daily Brief. Gemini can now proactively flag what matters most in an easily digestible to-do list, so you’re ready for the day before you even finish breakfast.

Copy and paste this into your codex: “Look through my recent Codex sessions and identify repeated workflows or repeated asks. For anything I keep doing manually, suggest: 1. a skill if it is a reusable workflow 2. a custom subagent if it is a bounded role or investigation task Focus on practical things like CI failures, PR reviews, changelogs, docs updates, release prep, debugging, and test triage. Create the useful ones only. Keep them simple.”

After a couple more days with Composer 2.5, I've got a pretty good sense of what it can do for game dev, specifically this mouse cursor racing game I'm building. It nailed ~80% of the features I threw at it, from planning to execution. Pretty amazing. I did have to switch to Opus 4.7 MAX a few times for features that need stronger visual understanding, like adding a 360 loop to the track or nailing a specific visual effect I had in mind. But man, Opus 4.7 MAX is expensive. Composer 2.5's visual understanding is weaker than Opus 4.7, but for most other things it's pretty damn close, and 10x cheaper. So it's now my default. The beauty of Cursor is I can switch models whenever I want, so I'm never stuck on one. Really excited for the larger incoming model. I have a feeling it's going to shine at planning. Can't wait!

This is evoBOT, a robot helper developed by Germany’s Fraunhofer Institute for Material Flow and Logistics. It can grasp and carry goods to support cargo workers in transporting packages. evoBOT can also move smoothly across uneven terrain, including bumpy surfaces and sloping ground.

Some of you noticed limits drained faster in Codex, we root caused it to an optimization that we rolled back that had an impact on cache hit rates when compacting across long running sessions. We fixed this and have now reset usage limits for all accounts. Enjoy the weekend.
