Wrapture is a new project from Graham, who previously developed wrapt (a 20+ year old Python monkey patching library) and built the first version of the New Relic Python agent - the library that instruments your app so New Relic can show you watt its doing.
Wrapture provides the ability to both mock and instrument code in the same toolset. You can use it in tests for "did this method fire" or "when this method fires return this dummy data instead", and you can also use it to instrument your code to measure what's called and how long things take.
It can instrument existing Python code without you modifying that code - you can instead define a TOML file saying which methods you want to instrument and Wrapture will live patch the code for you. This means you can instrument any Python code that you need to run without changing it, and export the results to OpenTelemetry.

Both applications work correctly and fulfill the requirements. The Qwen one (which used the default xhigh reasoning setting) is massively over-engineered. The Glimmer one used whatever their default in LM Studio is and I would argue is a tiny bit under-engineered.
Weirdly the Glimmer one doesn't work with images on other domains like https://static.inaturalist.org/photos/714731804/large.jpg - it fails with a CORS error, but you don't need CORS to load images and detect their width and height, and the Qwen one handles that URL just fine.
That's because Glimmer added this unnecessary line:

Both applications work correctly and fulfill the requirements. The Qwen one (which used the default xhigh reasoning setting) is massively over-engineered. The Glimmer one used whatever their default in LM Studio is and I would argue is a tiny bit under-engineered.
Weirdly the Glimmer one doesn't work with images on other domains like https://static.inaturalist.org/photos/714731804/large.jpg - it fails with a CORS error, but you don't need CORS to load images and detect their width and height, and the Qwen one handles that URL just fine.
That's because Glimmer added this unnecessary line:

On the one hand, if you really want to unlock the potential of coding agents you can get a whole lot more value from them if you don't force yourself to read every line of code they produce for you.
On the other hand, that's clearly a terrible idea! These machines make mistakes. Unreviewed code is the most obvious form of technical debt - sure, you'll get a boost in the short term but how much will you regret it later?
Something that's helped me a bit is thinking about how I've collaborated with other teams at large companies. If my team depended on some other team's product I wouldn't review every line of their code before using it - I'd start using it, then if I ran into problems I'd dig into the code to see if I could figure out the problem.
That works with human teams because humans can take accountability for their work. Agents can't.
And yet... the more time I spend with specific agents, the more I learn what kind of problems I can "trust" them with.
If I ask Codex or Claude Code to build me an API endpoint that queries a database and returns JSON, including with tests, they're going to get that right. I can glance at the shape of the tests, hit the endpoint with curl, and be confident that the job is "good enough" without me reviewing every line.
Over time, the pool of tasks like that which I'm confident they're not going to screw up has grown.
A big part of the craft of using these things is developing the instincts to know when you need to dive in to the details and when you can relax a little.
Having a lot of experience helps a ton here. I have 25+ years of experience to help me make these judgement calls. If it's security adjacent I know to review much more thoroughly. I have a good idea for the kind of mistakes that can be made. I know what shape I like my tests in, and how to both manually and get-the-agent-to-manually test things.
Coming up with ways to help the agent prove that the code works is another interesting challenge. I've experimented with a few projects around that now: https://simonwillison.net/2026/Feb/10/showboat-and-rodney/ and https://simonwillison.net/2026/Jun/30/shot-scraper-video/

And yet... the more time I spend with specific agents, the more I learn what kind of problems I can "trust" them with.
If I ask Codex or Claude Code to build me an API endpoint that queries a database and returns JSON, including with tests, they're going to get that right. I can glance at the shape of the tests, hit the endpoint with curl, and be confident that the job is "good enough" without me reviewing every line.
Over time, the pool of tasks like that which I'm confident they're not going to screw up has grown.
A big part of the craft of using these things is developing the instincts to know when you need to dive in to the details and when you can relax a little.
Having a lot of experience helps a ton here. I have 25+ years of experience to help me make these judgement calls. If it's security adjacent I know to review much more thoroughly. I have a good idea for the kind of mistakes that can be made. I know what shape I like my tests in, and how to both manually and get-the-agent-to-manually test things.
Coming up with ways to help the agent prove that the code works is another interesting challenge. I've experimented with a few projects around that now: https://simonwillison.net/2026/Feb/10/showboat-and-rodney/ and https://simonwillison.net/2026/Jun/30/shot-scraper-video/
I think "when should you review the code" is the most interesting question, and the answers are still very much being figured out.","created_at":"2026-08-14T00:39:35Z","created_at_i":1786667975,"objectID":"49293486","parent_id":49292603,"story_id":49290299,"story_title":"Understanding is the new bottleneck","story_url":"https://www.geoffreylitt.com/2026/07/02/understanding-is-the-new-bottleneck","updated_at":"2026-08-15T22:42:56Z"},{"_highlightResult":{"author":{"matchLevel":"none","matchedWords":[],"value":"simonw"},"comment_text":{"matchLevel":"none","matchedWords":[],"value":"This talk is also available on YouTube: https://youtu.be/WkBPX-oDMnA?is=ojFaLX2onMn3ARhi"},"story_title":{"matchLevel":"none","matchedWords":[],"value":"Understanding is the new bottleneck"},"story_url":{"matchLevel":"none","matchedWords":[],"value":"https://www.geoffreylitt.com/2026/07/02/understanding-is-the-new-bottleneck"}},"_tags":["comment","author_simonw","story_49290299"],"author":"simonw","comment_text":"This talk is also available on YouTube: https://youtu.be/WkBPX-oDMnA?is=ojFaLX2onMn3ARhi","created_at":"2026-08-13T21:09:14Z","created_at_i":1786655354,"objectID":"49291901","parent_id":49290299,"story_id":49290299,"story_title":"Understanding is the new bottleneck","story_url":"https://www.geoffreylitt.com/2026/07/02/understanding-is-the-new-bottleneck","updated_at":"2026-08-14T11:17:06Z"},{"_highlightResult":{"author":{"matchLevel":"none","matchedWords":[],"value":"simonw"},"comment_text":{"matchLevel":"none","matchedWords":[],"value":"They seem to have reduced the price of 3.6 Flash at the same time that they released this 3.7 model:

They say training run in the video, and later mention a \u201creward signal to judge how well they\u2019re doing\u201d, so I guess this really was about training a model, not evaluating one that was already trained.)
The more I think about this the more I suspect that the fact this happened while training a new model is key to understanding what went wrong.
In RLVR - Reinforcement Learning with Verifiable Rewards - you set the model a goal and have it take any steps necessary to achieve that goal.
Clearly one aspect of OpenAI's training here is to RLVR their models for cybersecurity tasks. Just like pre-training benefits from dumping in vast sources of knowledge, the more tasks you can feed into RLVR the more of a general purpose capable model you get at the end.
This also helps explain why the models had nothing to cause them to hold back. Those safety behaviors are added much later in the process.
AND it explains (but does not excuse) why monitoring was so lax. If you're training a new model like this you presumably set it thousands of tasks like this in parallel. I can see how you might miss that a tiny subset of your training agents have started leaving each other messages in filenames on your packaging server.
Someone once told me that you can't just leave the racist materials out of your training data if you want a non-racist model: it has to have seen examples of racism in order to later be taught that racism is bad.
I can see echoes of that here. If your model doesn't know how to aggressively hack things how do you later teach it not to?

It's also fun promoting "make it tastier" once or twice after each recipe just to see what happens.","created_at":"2026-07-24T10:07:08Z","created_at_i":1784887628,"objectID":"49033342","parent_id":49032955,"story_id":49031409,"story_title":"Claude Cookbook","story_url":"https://platform.claude.com/cookbook/","updated_at":"2026-07-25T13:35:40Z"},{"_highlightResult":{"author":{"matchLevel":"none","matchedWords":[],"value":"simonw"},"comment_text":{"matchLevel":"none","matchedWords":[],"value":"Exploiting, not exploring."},"story_title":{"matchLevel":"none","matchedWords":[],"value":"OpenAI\u2019s accidental attack against Hugging Face is science fiction that happened"},"story_url":{"matchLevel":"none","matchedWords":[],"value":"https://simonwillison.net/2026/Jul/22/openai-cyberattack/"}},"_tags":["comment","author_simonw","story_49015639"],"author":"simonw","comment_text":"Exploiting, not exploring.","created_at":"2026-07-24T09:19:46Z","created_at_i":1784884786,"objectID":"49033057","parent_id":49031527,"story_id":49015639,"story_title":"OpenAI\u2019s accidental attack against Hugging Face is science fiction that happened","story_url":"https://simonwillison.net/2026/Jul/22/openai-cyberattack/","updated_at":"2026-07-24T09:24:21Z"},{"_highlightResult":{"author":{"matchLevel":"none","matchedWords":[],"value":"simonw"},"comment_text":{"matchLevel":"none","matchedWords":[],"value":"I think your head is in the sand if you prefer to believe that this was a hoax for marketing purposes as opposed to accepting how effective these models have become at exploit research.

The claim is not that there were stolen credentials in the sandbox - it's that the agent found a way OUT of the sandbox and gained access to the public internet, then obtained the credentials from there.
> This means the model had the ability to build resilient infra and open bidirectional ports. Create and deploy scripts/apps so it can maintain state across multiple VMs?
Yes. If you've spent much time with Fable 5 or GPT-5.6 Sol you shouldn't find that particularly surprising. These models can get a LOT done.
> I'd be curious to find out what kind of sandbox
My best guess right now is a container with networking disabled except for the IP address of a dedicated HTTP proxy server which was running a proxy that only allowed access to PyPI and a few other packaging sites.
I wrote about how OpenAI's production version of that worked (based on Artifactory) back in January: https://simonwillison.net/2026/Jan/26/chatgpt-containers/#in...

The claim is not that there were stolen credentials in the sandbox - it's that the agent found a way OUT of the sandbox and gained access to the public internet, then obtained the credentials from there.
> This means the model had the ability to build resilient infra and open bidirectional ports. Create and deploy scripts/apps so it can maintain state across multiple VMs?
Yes. If you've spent much time with Fable 5 or GPT-5.6 Sol you shouldn't find that particularly surprising. These models can get a LOT done.
> I'd be curious to find out what kind of sandbox
My best guess right now is a container with networking disabled except for the IP address of a dedicated HTTP proxy server which was running a proxy that only allowed access to PyPI and a few other packaging sites.
I wrote about how OpenAI's production version of that worked (based on Artifactory) back in January: https://simonwillison.net/2026/Jan/26/chatgpt-containers/#in...

I usually don't use the term much myself because I don't think it's clear and I ambiguous, but I stumbled and let it sneak into this piece. I think I was influenced by the Hugging Face post I quoted.
I expect OpenAI would agree with you that "the lack of a real sandbox or airgap is nothing short of irresponsible on OpenAI's part".

I've certainly seen probabilistic classifiers referred to as guardrails many times by many different people.
I usually don't use the term much myself because I don't think it's clear and I ambiguous, but I stumbled and let it sneak into this piece. I think I was influenced by the Hugging Face post I quoted.
I expect OpenAI would agree with you that "the lack of a real sandbox or airgap is nothing short of irresponsible on OpenAI's part". They have clearly invested a lot in those systems for their production models, but in this case they had deliberately turned a bunch of them off for a research project.
