6 Years of AI Progress: ModernBERT Finally Replaces BERT

After six years, we finally have a worthy replacement for BERT! Meet ModernBERT, the state‑of‑the‑art encoder‑only model that outshines its predecessors with larger context, improved downstream performance, and blazing‑fast speeds. Designed as a drop‑in upgrade for BERT‑like models, ModernBERT is a great choice for retrieval, classification, and code‑related applications. The video covers several topics: at 00:00 we discuss encoders and decoders, at 00:46 we cover RAG, at 02:35 we introduce ModernBERT, at 03:13 we talk about training data, at 04:12 we discuss context length, at 05:11 we explain the attention mechanism, and at 06:43 we show a ModernBERT example.
