Satoshi 7B - fine-tuned Bitcoin LLM

09 Jun 2026

Reading time ~1 minute

Satoshi 7B is a Bitcoin-focused LLM I worked on when I was at Spirit of Satoshi.

It was based on Mistral 7B Instruct, fine-tuned with LoRA and later aligned with DPO, then released on Hugging Face.

My work on it included:

  • curation and cleaning of training data
  • evals
  • continued pre-training
  • LoRA fine-tuning
  • DPO alignment
  • data augmentation

The goal was simple: a model that answered Bitcoin questions from a Bitcoin-native frame instead of falling back to generic internet priors.
