A 125M-parameter Llama-style base language model , pretrained from scratch on a legal/financial corpus (US case law + SEC filings + a web slice, ~2.19B tokens). Pretraining: 5 epochs, 8xH100. Held-out validation perplexity: 8.5 . This is a base COMPLETER, not a chat model. Prompt it with the start of a sentence and it continues in the legal register.
