ModernBERT is an Open Source encoder language model (BERT family) developed by Answer.AI and LightOn in collaboration with additional partners and released in December 2024. It is a bidirectional, masked language model trained on 2 trillion Tokens of text and code, supporting a native context window of up to 8,192 Tokens. ModernBERT is available in two sizes (Base with 149M and Large with 395M parameters) and serves as a drop-in replacement for classic BERT models in tasks such as classification, Retrieval, and semantic search.
