Canis.teach - Ministral-3B Instruct (Science)

LoRA adapters for the Science tutor in the Canis.teach suite.

Base Model: unsloth/Ministral-3-3B-Instruct-2512
Release: CanisAI/teach-science-ministral-3b-r2
Project: Canis.teach - Learning that fits.
Subject: Science

What is this?

This repository provides LoRA adapters fine-tuned on Science tutoring dialogues. Apply these adapters to the base model to enable subject-aware, didactic behavior without downloading a full merged checkpoint.

The model is designed to teach, not just answer - providing step-by-step explanations, hints, and pedagogically structured responses.

For ready-to-run merged models or Ollama-friendly GGUF quantizations, see the "Related Models" section.

Quick Start

Installation

pip install transformers peft torch

Usage (LoRA)

python

from transformers import AutoTokenizer, AutoModelForCausalLM
from peft import PeftModel

base = "unsloth/Ministral-3-3B-Instruct-2512"
adapter = "CanisAI/teach-science-ministral-3b-r2"

tokenizer = AutoTokenizer.from_pretrained(base, use_fast=True)
model = AutoModelForCausalLM.from_pretrained(
    base, 
    device_map="auto",
    torch_dtype="auto"
)
model = PeftModel.from_pretrained(model, adapter)

# Example prompt
prompt = "Explain the process of photosynthesis."
inputs = tokenizer.apply_chat_template(
    [{"role": "user", "content": prompt}],
    add_generation_prompt=True,
    return_tensors="pt"
).to(model.device)

outputs = model.generate(
    inputs,
    max_new_tokens=512,
    temperature=0.7,
    top_p=0.8,
    top_k=40,
    do_sample=True
)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Training Details

Base Model: unsloth/Ministral-3-3B-Instruct-2512
Training Method: Supervised Fine-Tuning (SFT) with LoRA
Framework: Unsloth + TRL/PEFT
Data: Canis.lab-curated Science tutoring dialogues
Target Modules: Query, Key, Value, Output projections, MLP gates (gate, up, down)
Rank: 32
Alpha: 32

Intended Use

Primary: Subject-aware tutoring for Science education
Applications: Educational prototypes, tutoring systems, research
Approach: Stepwise explanations, pedagogical hints, rubric-aligned responses
Target Audience: Students, educators, researchers

Model Behavior

The model is optimized for:

Clear, step-by-step explanations
Appropriate difficulty progression
Encouraging learning through hints rather than direct answers
Subject-specific pedagogical approaches
Maintaining educational standards and accuracy

Recommended Settings

For optimal tutoring behavior:

Temperature: 0.6-0.8
Top-p: 0.8-0.9
Top-k: 20-40
Max tokens: 512-1024

Safety and Limitations

Important Considerations:

Human oversight required for educational use
May occasionally hallucinate or oversimplify complex topics
For fact-critical applications, consider RAG with verified curriculum sources
Follow your institution's data privacy and AI usage policies
Not a replacement for qualified human instruction
