On file deletions. We’ve investigated a handful of reports where GPT-5.6 unexpectedly deleted files.

What we have found is that this most commonly occurs when:
- Full access mode is enabled and codex is run without sandboxing protections, including without auto review being enabled
- The model attempts to override the $HOME env var to define a temporary directory.
- The model makes an honest mistake and mistakenly deletes $HOME instead.

This is of course not how we want the system to behave, even when a user operates the model in full-access mode without the safeguards of our sandbox or without using auto review which checks for these kinds of high risk actions and rejects them.

We are taking steps to mitigate this risk including by updating the developer message, guiding more users towards safer permission modes, and adding additional harness safeguards. Even though this happens extremely rarely, we’ll share a detailed post-mortem in the coming days that goes into more details and what we are doing to minimize risks further.

We've open-sourced Grok Build and have reset usage limits for all users.

Open sourcing Grok Build allows anyone to support making a reliable and robust harness. Check out our code, including the Git repo for the Grok Build CLI.

Incredibly proud of the team. After countless late nights, Inkling is out, and I especially want to highlight the post-training stack and RL recipes behind it.

A few of my favorite details:

We scaled our largest RL run to 30M+ rollouts and thousands of continuous training steps—with no collapse, no restarts, and stable KL and entropy throughout. Reasoning performance improved log-linearly from the SFT initialization all the way to the released checkpoint. A number of innovations under the hood made this possible, and the result is a strong testament to our post-training technology.

We trained controllable thinking effort directly through RL. By varying the system message and per-token cost, the model learned to trade off tokens and performance on demand.

We also saw an emergent shift in reasoning style: as RL progressed, the chain of thought became increasingly compressed, shedding grammatical overhead. Inkling reasons like a caveman mathematician—a distinctive style unlike that of other open-source models.

We’re also previewing Inkling-small today and plan to release it very soon. It is exceptionally capable for its size, and we expect the community will find it broadly useful.

Building a simple, stable, and scalable RL stack in such a short time was something few thought possible. This team proved otherwise.

[Thinking Machines @thinkymachines]

Today, we are introducing Inkling.

Inkling reasons efficiently across text, image, and audio modalities. We are making the full weights available.

Claude Code artifacts can now call MCP connectors, letting you build dashboards and apps that can fetch information and take actions for each viewer on demand.

Available on Pro, Max, Team, and Enterprise plans. Not available on publicly-shared artifacts.

Once we have completed our review for security vulnerabilities, we will make the entire codebase of 𝕏 open source, with no exceptions.

Moreover, we will invite third party reviewers to examine the system that is running to confirm that the open source code is what is running.

Trust through total transparency is the only thing that should be believed.

金属的な質感とは真逆のアプローチで工芸品のようなレンズを作りたくて、『Dragonic Armor（クリスタルVer.）』を試作。

コーヒーを淹れるときに使っているKEYのクリスタルドリッパーからアイディアを得て制作しています。洞窟の奥深くにひっそりと暮らすクリスタルドラゴンをイメージ。

普段取り扱っているものとは素材の特性が違い過ぎて、嵌め合い含めたモデルの再調整をあと2ループぐらい回す必要がありそうです。実用にはまだまだ遠いですが、まるでガラスを纏ったかのような見た目。滅茶苦茶カッコいいな…！！

Pro tip: when prompting Codex with really difficult /goals, ask it to "write a goal for another thread to achieve this and babysit it until it figures it out"

By doing so, you'll add built-in steering and another layer of taste verification (that's how this video was made)
