I’ve just tested Jev, from Typesafe, launch this week. It’s truly extraordinary.
Jev is a model that allows you to analyze discursive texts, such as essays, articles, and reports, with performance far superior to current models (even the most advanced ones), at an incredibly faster speed and at a surprisingly lower cost.
I did a test of grading essays and published it on my Github: [GitHub - mgarlabx/Jev-Enem · GitHub](https://github.com/mgarlabx/Jev-Enem)
If you would like to know more, please do not hesitate to contact me.

Jev is not open source. Why are you talking about it on OEGlobal?

This is a cool use case! Thanks for sharing, @Mauricio… 🙂
Twitter/X is on fire about Jev, and it’s fascinating to see that there are already [hundreds of use cases](https://github.com/yibie/awesome-jev) for a project that is literally three days old.
What seems especially interesting to me is cheap/fast/reliable computer use. We’ll see how these “system one thinking” models evolve…

Not to speak for Mauricio but my guess would be that Jev can be useful in education, like his demo project showed. Many folks here use Mac/Windows (not open either), and a mix of both proprietary and open solutions. “As open as possible, as closed as necessary.”
Also, for those interested, it took literally only hours for open Jev alternatives to pop up. So the internet is working exactly as intended… 🙂

Jev is a tool, like many others, that enables the creation of open solutions for education. I have devoted a great deal of my time to this, and all the solutions I develop are open. But many of them use proprietary tools, including OpenAI, Anthropic, etc. Take the case of OpenRouter: it provides access to several open tools, but through paid providers. What matters, in the end, is what we do with the tools.
At the moment, I am working on improving an open standard (“schema”) for adaptive learning, with inference prediction in both Large Language Models (LLMs) and System One Models (SOMs). Jev is a SOM, but others will come. In fact, they are already arriving, as is the case with Laya, which is indeed open ([https://medium.com/@christian.graham\_49279/laya-a-free-local-alternative-to-jev-and-it-can-even-play-doom-ish-42e2292e541e](https://medium.com/@christian.graham_49279/laya-a-free-local-alternative-to-jev-and-it-can-even-play-doom-ish-42e2292e541e)). But it has an MLOps cost that Jev does not have.

Thanks for explaining the connection.
