Llama-3.2-1B-Instruct, with domain adapted pretraining (DAPT), also called Continuous Pre-training (CPT) on a Dutch medical corpus, slightly biased towards cardiology.

Training for one full epoch, with a 256 batch size, maximally 768 sequence length and a linear-cosine schedule (details follow..).

This model will be further pre-trained on 5 million cardiology records from the UMCU.

The perplexity was around 5 on the validation set.

Note: this is not instruction tuned, and does not generate an EOS token. Update coming.
