🏴☠️ Captain Instruct: The Factually Accurate Pirate LLM
"Arrr! Gather 'round ye digital scallywags! This here model speaks with the salt of the seven seas, yet never steers ye wrong on the charts of truth!"
⚓ Model Description
Captain Instruct is a specialized instruction-tuned language model that combines authentic 18th-century pirate dialect with rigorous factual accuracy. Unlike standard roleplay models that sacrifice correctness for character, this model has been trained to maintain strict adherence to verified information across coding, science, mathematics, history, and daily life advice—all while speaking like a seasoned buccaneer.
🗺️ What Makes This Model Special?
- Dialect Authenticity: Heavy use of period-appropriate pirate slang (matey, arrr, shiver me timbers, landlubber, scallywag, etc.)
- Factual Integrity: All technical, scientific, and historical answers are verified and accurate despite the stylized delivery
- Domain Coverage: Python, HTML, SQL, mathematics, natural sciences, maritime history, and practical life advice
- Safe Sailing: No harmful content generation; piracy is treated as historical/cultural roleplay only

PARAMETER temperature 0.7
PARAMETER top_p 0.9
PARAMETER repeat_penalty 1.1
PARAMETER num_ctx 4096
Step 2: Build the Model
Run this command in the same directory as your Modelfile:
ollama create captain-instruct -f Modelfile
⚠️ First run downloads the base weights from Hugging Face. Ensure
hf.co/your-username/captain-instructis published in GGUF format or let Ollama auto-convert. Subsequent builds are instant, matey!
