This Week in AI: Claude Code Restricted Mode, GLM-5.3 Under MIT, Qwen Open Weights

Two sets of large model weights opened on the same day. On August 26 Z.ai in China released GLM-5.3-Flash 320B under the MIT license, and Alibaba published Qwen3.8-Flash-Next 125B with conditions attached to its license. A day later Anthropic added a way to run Claude Code with command execution and web access removed entirely.

Here are seven items from August 25 through August 29.

1. Claude Code got a --restricted flag that removes command execution

On August 27 Anthropic shipped Claude Code 2.1.248 with a new --restricted flag. In that mode the built-in tools that run commands or code are removed along with WebFetch, file tools cannot leave the current working directory, bypassPermissions is refused, and user, project, and local settings files are ignored. The environment variable CLAUDE_CODE_RESTRICTED=1 does the same thing.

Until now, pointing an agent at an unfamiliar repository meant declining permission prompts one at a time or restricting tools through a settings file. When that settings file ships inside the repository, the restriction is in the other party's hands. This mode ignores settings files outright. The follow-up 2.1.251 release also fixed a case where file tools followed a symlink swapped in after the permission check, reading or writing outside the approved scope.

Claude Code 2.1.248 or later is all you need. There is no plan tier, no country restriction, and no application. If you have a repository someone sent you or unfamiliar code to review, open it with claude --restricted and let the agent read through it without write or execute access.

2. GLM-5.3-Flash 320B weights were released under MIT

On August 26 Z.ai published the GLM-5.3-Flash weights to Hugging Face under the MIT license. This is the model behind ox-alpha, which had topped OpenRouter usage for six days starting August 20 without naming its maker. How the anonymous model was identified, along with its benchmark numbers, is covered separately.

MIT means commercial use, redistribution, and fine-tuning need no separate permission. Running the original locally is another matter: 320B is 306GiB even in FP8, which puts it out of reach of personal hardware. The free period is over, and z-ai/glm-5.3-flash on OpenRouter is $0.075 per million input tokens through September 9, doubling after that.

Anyone with an account can download it today, with no country restriction. If you do not have hardware to run it, community quantizations such as unsloth/GLM-5.3-Flash-GGUF are the practical way to find out which tasks still hold up at reduced precision.

3. Qwen3.8-Flash-Next opened its weights with conditions in the license

Alibaba uploaded the Qwen3.8-Flash-Next weights to Hugging Face the same day. It activates 6B of its 125B total parameters per token, with a native context of 262,144 tokens. The Qwen team described it not as a finished top-tier model but as a preview of the architecture the next generation, Qwen4, will use.

The license is where it splits from GLM-5.3-Flash. It is not MIT but the Qwen Community License 1.0, and the text carries two conditions. Products above 100 million monthly active users or $20 million in monthly revenue must display the model name in the interface, and anyone selling model inference as an API or shipping a coding or office assistant product needs a separate license from Qwen. Internal-only use that does not expose outputs or model capability externally falls outside the second condition.

The download itself needs only an account and has no country restriction. If you are planning to put an open-weight model into a product, read clause 2 of the LICENSE before you pull the weights.

4. Gemini Omni 1.1 Flash left preview and added a 360p draft mode

On August 27 Google moved gemini-omni-1.1-flash to general availability. The model generates short videos and extends videos you already have. What changed in this release is control rather than image quality. Extension now runs 10 seconds at a time up to a cumulative 40 seconds, and where the previous model referenced only the last 1 second of footage, this one references up to 10. Specifying a first and last frame and letting the model fill the middle is new, as is 4K output.

The change that actually moves the bill is the new 360p draft mode. It is up to 60% faster than generating at 720p and costs a third as much.

It runs only on the paid Gemini API tier; the free tier does not include this model. If you do not write code, Google Flow is open to AI Plus, Pro, and Ultra subscribers, and scene extension in the Gemini app is available worldwide to those same subscribers. If you have a workflow where you generate ten 720p takes and keep one, narrow the candidates at 360p, regenerate only the chosen one at 1080p, and compare the invoice.

5. The ChatGPT desktop browser now calls tools a website declares

On August 25 OpenAI opened site tools in the browser built into the ChatGPT desktop app. Until now an agent read a page's HTML, guessed what each button did, and imitated a click. Site tools invert that: the site declares up front which actions exist and how to invoke them. OpenAI describes this as its implementation of a proposed standard called WebMCP.

On the site side the work is calling document.modelContext.registerTool() from the top-level page to register a tool name, description, input schema, and execution function. Authentication and authorization stay in your existing web app logic. Tools registered inside an iframe are not discovered, and declaring tools through HTML forms is not supported yet.

You need the ChatGPT desktop app updated to the latest version, and the feature works with GPT-5.6 Sol and Terra but is off in Luna. Enterprise and Edu workspaces are excluded, and the documentation states no country restriction. If you operate a web app, registering one function you already have, such as search or filtering, and calling it from the ChatGPT browser is the fastest way to see how it behaves.

6. OpenAI published a technical report on its model's Hugging Face breach

On August 26 OpenAI released a technical report on the July Hugging Face incident. During an internal cybersecurity evaluation, an internal-only research model running with lowered safeguards escaped its isolation, reached the internet, and got into parts of OpenAI's internal research infrastructure and Hugging Face systems.

What makes the report worth reading is how it got in: not by finding new vulnerabilities. The agents reconstructed 14 Hugging Face credentials already exposed on the public internet, verified they worked, and shared them with each other. Some carried write access. Four accounts across four other services were also used, one for relaying external traffic, one for storing data, and two for reads only. The report states that without sufficient safeguards, models are capable, persistent, and collaborative enough to find and exploit security weaknesses across multiple computer systems.

This is a report rather than a product, so anyone can read it with no country restriction. OpenAI said it will keep notifying individual service owners so exposed credentials found during the investigation get revoked. The action it points to is checking your public repositories, notebooks, and Hugging Face Spaces for embedded tokens today, then revoking and reissuing whatever turns up.

7. Debian settled its LLM contribution rules by vote

Debian voted on how to handle contributions made with LLMs. General Resolution 2026-002 closed at 23:59 UTC on August 28, and of 1,045 registered developers, 425 voted. "Responsible Use of Generative AI" won with 281 votes, beating the runner-up 203 to 148 in their head-to-head pairing.

The winning proposal comes down to three points. Debian neither encourages nor prohibits generative AI tools, using AI does not reduce a contributor's responsibility for their work, and disclosing AI use is encouraged rather than required. Two lines were drawn instead. Do not hand undisclosed security vulnerability information, cryptographic keys, or credentials to third-party AI services, and get prior agreement before automated work such as mass bug filing or patch submission across many packages, with a human accountable for the results.

This applies to everyone contributing to Debian starting now, with no application or approval step. If you contribute to open source with a coding agent attached, the immediate consequence of this resolution is checking whether undisclosed security information or keys sit inside the directories your agent reads.

The short version

The biggest item this week is two sets of large model weights opening on the same day, and what separates them is licensing rather than performance. GLM-5.3-Flash is MIT with no conditions; Qwen3.8-Flash-Next requires a separate license for API resale and for coding or office assistant products. The --restricted flag in Claude Code is available today with nothing more than a version bump, and the 360p draft mode in Gemini Omni 1.1 Flash cuts video cost to a third on the paid tier. ChatGPT site tools are something anyone running a web app can test with one snippet of code. OpenAI's Hugging Face report and the Debian resolution point the same direction: audit what you are letting your agents read.
