quizforge

Generate a deep, mixed-format question bank from any source material, then grade it — deterministic where it can, LLM where it must. Bring your own chat model.

quizforge is the engine behind a training/readiness feature: it drafts far more questions than any single test shows (multiple choice, fill-in-the-blank, match-the-following, short answer, and free-response scenarios), samples a fresh shuffled test on each attempt — so two learners rarely see the same one — and grades every format. MC/fill/match are graded instantly with no model call; open-ended answers are scored 0–1 with coaching feedback by an LLM you provide.

• Model-agnostic — pass any LangChain-style chat model (with_structured_output). No SDK is bundled.
• Deep bank, anti-sharing sampling — unseen-first, difficulty-spread draws per a configurable blueprint.
• Cheap grading — only open-ended answers cost a model call; everything else is local and free.
• Plain dicts in, plain dicts out — YAML/JSON-friendly, easy to store and template.

Install

pip install quizforge

Bring a chat model from whichever provider you use, e.g.:

pip install langchain-openai   # or langchain-anthropic, etc.

Quickstart

Generate a bank

from quizforge import generate_bank
from langchain_openai import ChatOpenAI

llm = ChatOpenAI(model="gpt-4.1", temperature=0.4)

material = open("citrix_lesson.md").read()
new_questions = generate_bank(
    material, llm,
    targets={"mc": 40, "fill_blank": 20, "match": 12, "short": 16, "freetext": 12},
    existing=[],                       # pass your current bank to top it up
    coverage="At least half should be applied incident-response scenarios.",
)
# -> list of dicts with id/type/difficulty + per-format fields. Store as you like.

generate_bank only produces the shortfall to reach targets, validates each question, and never duplicates an existing prompt — safe to re-run to grow a bank.

Sample a test

from quizforge import sample_test, DEFAULT_BLUEPRINT

test = sample_test(bank, blueprint=DEFAULT_BLUEPRINT, seen_ids=already_seen)
# DEFAULT_BLUEPRINT draws mc8 / fill4 / match2 / short4 / freetext2 = 20, shuffled.

Grade

from quizforge import grade_fill_blank, grade_match, grade_open_answer

grade_fill_blank(q, "ICA")                 # {"score": 1.0, "correct": True, ...}
grade_match(q, {"0": "RDP", "1": "ICA"})   # per-pair partial credit
grade_open_answer(q, learner_text, llm)    # QuizGrade(score, verdict, feedback, ...) or None

grade_open_answer returns None if the model was unavailable — exclude that question from the attempt's max score rather than penalizing the learner.

Question shapes

Each question is a dict with id, type, difficulty, prompt, plus:

• mc — choices: [str], answer_idx: int, explanation: str
• fill_blank — accepted_answers: [str], explanation: str
• match — pairs: [{left, right}], explanation: str
• short / freetext — model_answer: str, rubric: [str]
