It did refinement by using OpenAI to create synthetic data.
But it now exists, and OpenAI seems to have no way to control Deepseek, or any legitimate claim they can enforce to stop it.
Oops.
We can quibble over how valuable each of these things individually is, but it's not just toys. It's foundational tooling used all over the place that the larger community pretty just got for free. They've also been some of the biggest contributors to the Linux kernel.
To be fair, I don't know that we needed Google et al for this. We used to get this kind of thing from DARPA and university researchers, but Google and Facebook and friends made so much money from ads that they hired away all the best researchers so they no longer work at universities, at the same time government was hollowing out funding for basic research.
We could get this thing from real public sources if we made the public investments, but I don't know that the political will or taxpayer willingness exists to do that now. We need to get it from somewhere.
You can now travel anywhere in the world and communicate in the local language. Using offline models that translate between any two languages. That’s almost literally biblical magic levels of social good.
(Plus we got amazing image recognition tech, LLMs, voice and NLU stuff, AlphaFold for protein analysis, etc)
I'm a happy DuoLingo user, but educational software with an owl-with-a-BBL mascot is not going to be a trove of translation capabilities.
I don't think they have any significant data collected, nor do they do any handwritten anything.
> But wait – how could a beginner-level student translate advanced sentences? The solution that Duolingo employs uses the power of crowdsourcing, which involves many students offering their attempts at translating individual sentences. As each student submits a sentence, they can rate others’ translations, and the most highly rated translations “rise to the top.”
Over time, entire documents are translated and students gain many skill points for their language practice. It’s easy to see how the data collected from users could be useful to improve the algorithms that underly computer translation[…]

FWIW, I like Duolingo and think it is a healthy and productive use of gamification, but that does come at the cost of pure efficiency and comprehensive treatment of grammar. It’s best when paired with other tools.
Most people’s problem with learning a language is not speed, it’s the quit rate.
