yes but no caching.
It's probably impossible to detect ALL languages without training for them specifically, but there's good generalization happening. Our model is a unified model rather than a separate model per language. We started out with language-specific models but found that the unified approach yielded slightly better results in addition to being more efficient to train.
Ah - I misread:

Recall 91.5, F1 93.3

Candidly, it's a bit of a black box still. We hope to do some ablation studies soon, but we tried to have a variety of formatting and commenting styles represented in both training and evaluation.
I'm sure you can but there isn't really an adversarial motive for doing that, I would think :)
More details about how we eval'ed here:

I'd argue that knowing AI generated code shipped into production is the first step to understanding the impact of AI coding assistants on velocity and quality. When paired with additional context, it can help leaders understand how to improve proficiency around these tools.

Show HN: AI Code Detector – detect AI-generated code with 95% accuracy

https://code-detector.ai/

Hey HN,I’m Henry, cofounder and CTO at Span (https://span.app/). Today we’re launching AI Code Detector, an AI code detection tool you can try in your browser.The explosion of AI generated code has created some weird problems for engineering orgs. Tools like Cursor and Copilot are used by virtually every org on the planet – but each codegen tool has its own idiosyncratic way of reporting usage....

OK. I need to know how.
That’s because many of the patients refuse to wear masks as well.

“Seattle Is Dying” is a great investigative report about the problems and potential solutions to homelessness. Also applicable to SF.

To be honest, although I prefer organic chicken for health and ethical reasons, mass produced chicken tastes juicier and better.
I'm the founder of a real estate tech startup that caters to realtors.

This article was written before Opendoor and before a record breaking $10B was pumped into proptech in 2018.

The consensus now is that this industry is undergoing rapid change. At the bottom end of the market (maybe 10%), iBuyers like Opendoor will likely completely disrupt the traditional brokerage model. Next, you will see discount brokerages (Redfin, Purplebricks, et al) take more and more of the market. Full commission brokerages will still be the mainstream for the foreseeable future, but commissions will come down modestly, even for them.

As purchasing or selling a home is one of the most expensive, most emotional, and most intimidating transactions you will ever do, seeking the help of a real estate agent is generally a good idea. Increasing competition will create more options and more value for consumers than we've ever seen before and that's a good thing.

Please explain why you think reality is inherently better than a virtual reality. edit: By the way, I get the sense that you think this is a grim future. I do too, but I think this is irrational.
The truth is they are both right. Technology is accelerating but it is also changing directionally. It is no longer accelerating along a physical axis but instead along a virtual one. What Peter Thiel doesn't see is that the virtual curve will be even more transformative than the physical one. Physical technology has had hundreds of thousands of years to evolve but virtual technology will obsolete it in just a few decades. How? The answer starts out looking a little like Angry Birds but probably ends up more like the Holodeck.

The issue of measurement IS important. The problem with all of Peter Thiel's metrics is that they are inherently indicators of external activity. The triumph of the virtual curve reveals itself in the only metric that really matters: time.

All forms of technology have the same purpose: to optimize the utility obtained during a finite lifespan. Some forms of technology increase the utility per unit time, others simply increase the units of time we have left. Therefore, more and more time spent in virtual space is an indication that virtual technology is out competing the substitutes provided by physical technology. As we go higher up the virtual curve and technology becomes more advanced at fulfilling our emotional and psychological needs by moving bits instead of atoms, eventually physical progress will slow to baseline: literally life support (maybe with gamified life extension projects taking place in virtual land).

Alas, the last technology invented by man will not be the singularity, it will be near perfect virtual reality; closer to Angry Birds than Skynet.
