   I compared it to Jev in my current use cases and it's very inaccurate. 70% vs 94% . for classification, it's unacceptable.

      For _your_ classification it's unacceptable. The OP seems to have anticipated this and mentions you can fine tune it for your use case. Did you try that?

      I don't think the point is to displace Jev, but to show it's possible to build an MVP on open weights without years of work and millions of dollars.

      Why (presumably) an engineer would dismiss exploring a lightweight, custom alternative to locking into a fashionable PaaS, I'll never know.

         Not sure the task at hand here. But if it doesn’t require any reasoning/thinking and it’s just a classification task, it’s worth a shot to look into training your own classifier

         I’ve run some benchmarks. Using embeddings + logistic classifier, the architecture matches or beats Jev and Laya in all basic classification tasks (datasets tested: AG News, Emotion, MASSIVE Intent, Banking77) The type of task in which it does really well, especially against Laya, is classification with >50 classes

         The classifiers also run in <1ms, so they can be very fast and precise at the same time

         But this architecture has no “reasoning”, so it performs rather poorly on tasks that require it, like the ones from the XLNI dataset (Jev/Laya do a lot better on this one)

         For the latter cases, you could use add a local lightweight LLM, something like a Gemma model. Or even some basic MLP, depending on the tasks/data

            I have not personally reviewed the benchmarks, but recall seeing a post where a Linear SVM with bag-of-words features outperformed Jev on many simple NLP classification tasks, like the ones you cite. You don't even need embeddings!

               I've used LLM's to classify things for numerous projects and it's always really hard to beat linear classifier/decision tree over simple embeddings or even the sklearn HashingVectorizer. However, you DO need to trust your validated data, ground truths for this to work - but you should have these anyway to validate a Jev or similar solution.
