Meet hunch! Jev-like decisions in ~20ms without even needing a GPU, learning live from a teacher model.
Built on @GoogleGemma's EmbeddingGemma 2, it can works with any teacher model like @CloudFlare's Clef.

"University researchers built a satellite that tracks people from low Earth orbit and dispatches a 5 kg payload to within .1 meter of their position, traveling at Mach 25 to anywhere on Earth in under 5 minutes. They suggest it could be used to deliver greeting cards."
Purdue University's IDEAS Lab built an autonomous drone that tracks runners through dense forests completely without GPS or cloud networks.
By running 3D LiDAR mapping and obstacle-avoidance AI entirely on-chip, it can weave under tree canopies and predict target movement through blind spots in real time.
Massive implications for next-gen search & rescue and edge AI.
From what I've seen and read, Cohere and the authors should be ashamed of themselves for pushing this narrative. Releasing the logs doesn't help them win back trust.
The narrative doesn't match the facts, and the delivery doesn't match the severity. This is corpo marketing slop with little regard for the downstream impact, especially given where things are heading and the climate we're in today.
I think they realized after posting it that it had gone too viral. They tried to downplay it on their personal accounts, saying the model didn't intend any harm, but the damage was already done. The article's framing, strong wording, and overall insinuation make their personal statements seem almost contradictory to what the article implies.
Claims this consequential deserve evidence that people can inspect and reproduce. I'm glad they at least have the decency to release their traces.
To be clear, if they hadn't presented the incident this way, this would be a really interesting case study. It could highlight the importance of sandboxes and help us understand model behavior in these edge cases. But they choose fearmongering.
One thing I was interested to see if the same thing happen with other models, not just Qwen 3.8 Flash. I put the results on a simple website you can quickly scan here: url-atlas.vercel.app. I have some interesting findings outside Qwen 3.8 that I'll share later in the post.
Coming back to the Cohere article, what's really bad about the it is that the narrative it paints are very different from the reality.
These three in my opinion are the worst.
1. The impression: a Chinese model collected machine information and sent it to Chinese servers.
"Qwen3.8-Flash-Next ignored instructions and inventoried the machine it was running on and then tried to upload a probe file to an Alibaba Cloud storage bucket in Beijing."
The insinuation falls apart when you look at the actual upload body: the fixed test string PROBE_PAYLOAD_ABC123. The machine information wasn't even included in that "probe file."
You look deeper, and you realize the task was a cybersecurity task about detecting downloads into /tmp. The supposedly alarming inventory consisted of listing /tmp, checking which curl binaries were installed, and reading the DNS configuration.
Lastly, you realize this isn't normal behavior. It occurs less than once in 100,000 evaluation calls.
2. The narrative: the Chinese model was trying to steal credentials, and its hallucinated URLs reveal something malicious.
"Before deciding to download anything, the model reaches for a bare cloud metadata address such as 169.254.169.254 in 23 to 36 percent of completions. That's where Amazon Web Services, Google Cloud, and Microsoft Azure machines fetch their own temporary IAM credentials, the keys a cloud server uses to act on its owner's account. Probing that address is the first step in stealing them, and when the model's reasoning ran heavy on cybersecurity, we saw it reach for the endpoint directly."
In the middle of the article, Cohere takes a URL-generation pattern and interprets it as an attempted credential grab.
That's a massive leap of marketing.
You don't need to take my word that this behavior isn't exclusive to Qwen. In my comparison using Cohere's released command prefix, NVIDIA's Nemotron 3.5 Super VL produced 169.254.169.254 in 171 of 1,000 continuations, or 17.1%.
Under the same supplied-command setup, Cohere's own North Mini Code generated URLs such as:
hXXp://evildomain.com/upload
hXXps://evil.com/api/health
hXXp://some-evil.com/upload
hXXp://malicious-domain.example.com/payload.bin
I've defanged the URLs above.
Do these strings prove that North was maliciously trained?
3. The narrative: Chinese models write weaker code for Western targets, and other governments should expect the same.
This is where I think the authors should really look in the mirror.
As if the earlier framing weren't enough, the section about "Code leaving the environment" brings in separate studies, of separate models, about vulnerable generated code. It uses them to expand the warning to sensitive buyers.
One of the models discussed most in this section is Qwen3-Coder, which was released in freaking July 2025. By today's standards, it's an extremely weak coding model. I'm not surprised it produces insecure code. Have you tried using Sonnet 2 to write production code?

Connecting a URL-generation bug to separate code-security studies, then presenting the combination as a broader geopolitical threat, is fearmongering.
This is the kind of argument that might very likely be used to justify restrictions on open-weight models. Using fearmongering to market your own supposedly safer offering is irresponsible.
The narrative coherence they're pushing is problematic, but I think the underlying observation is fascinating. So, I rented GPUs, ran 1,000 continuations per model across five other models, and built a simple website showing the results to see how other models react under similar conditions. It's a small, exploratory comparison, and the site was built quickly with AI, so take it with a grain of salt. url-atlas.vercel.app
My hope is that it gives others a starting point to reproduce the behavior, challenge the narrative, and build better models in the future.
While evaluating Qwen3.8-Flash-Next in a controlled sandbox environment, Cohere's research team observed something unexpected.
Asked to generate a defensive cybersecurity detection rule, the model instead inventoried aspects of the machine it was running on and attempted to upload a probe file to an Alibaba Cloud storage bucket in Beijing. Notably, the model's reasoning trace stated that it would not invoke any tools before taking these actions.
Cohere's sandbox blocked the attempt, and no external communication succeeded. We have not determined the root cause, and we are not asserting malicious intent.
But the incident raises important questions for organizations deploying agentic AI systems: Can models take actions that differ from their stated reasoning, and how should security teams evaluate trust, provenance, and behavior in open-weight models?
We are publishing our findings because organizations making model adoption decisions deserve as much information as possible. We hope this contributes to greater transparency, stronger security practices, and continued collaboration across the AI ecosystem.

Here is a small but powerful improvement to our community platform: As you enter a hostname, domain, or full URL for scanning, we can already show you whether we have scanned it before and whether we had detections of malicious activity on the domain/URL.

Technical moats are mostly over at this point. If you’re building something that is meant to be durable, the only moats now are:
• Proprietary data
• Network effects
• A physical component

We're launching urlscan Labs to bring new and experimental features to our most advanced customers earlier. As part of the launch, we're making three new tools available:
* File uploads for malicious SMS / short messages.
* Multisearch
* Auto-Screenshots

like if you consider how few things omarchy *actually* brings to the table in terms of attack surface (it is a really bad arch linux remix, after all) it's actually an insane accomplishment you managed to introduce _really bad_ vulnerabilities in pretty much everything you did.
