# ModernBERT

7 Hacker News commenters recommended ModernBERT and 2 criticized it, November 2025 to November 2026. It was recommended in 5 of 13 months.

**Verdict:** Free open encoder model that people fine-tune for classification and embeddings; it learns quickly and works well as a starting point. Critics say it underperforms on some tasks.

## Why people recommend it

- Learns quickly and beats alternatives (2 comments): "ModernBERT was the clear winner. It learned faster and performed the task better by a significant margin" ([source](https://news.ycombinator.com/item?id=48626633)) "ModernBERT is amazing if you haven't used it before, worth spending time with" ([source](https://news.ycombinator.com/item?id=48729178))
- Good starting point for fine-tuning (3 comments): "it is very fruitful to start with an off-the-shelf embedding model like ModernBERT" ([source](https://news.ycombinator.com/item?id=49888224)) "Fine-tuning modernbert works even better but probably won't meet the criteria" ([source](https://news.ycombinator.com/item?id=47578954)) "embeddings are easy to fine tune" ([source](https://news.ycombinator.com/item?id=48018292))
- Useful embeddings for classical algorithms (2 comments): "ModernBERT for feature generation plus classical algorithms from scikit-learn works so well" ([source](https://news.ycombinator.com/item?id=48854201)) "it is very fruitful to start with an off-the-shelf embedding model like ModernBERT" ([source](https://news.ycombinator.com/item?id=49888224))

## What people warn about

- Underperforms on some tasks (2 comments): "Anything that required knowledge / familiarity mmBERT and ModernBERT post-trains performed much worse." ([source](https://news.ycombinator.com/item?id=49787750)) "ModernBERT didn't have the learning capacity for a single problem" ([source](https://news.ycombinator.com/item?id=49794750))
