fatg 0.1.1

Finnish Adaptive Tiered Generation — hardware-adaptive LLM inference for Finnish language learning content

FATG — Finnish Adaptive Tiered Generation

Hardware-adaptive LLM inference framework for Finnish language learning content. Runs on Apple Silicon (M1/M2/M3), NVIDIA GPUs, and CPU-only machines via Ollama — no cloud, no API keys, no cost.

Built for Lingo Deck — a Finnish language learning card game.

Features

• Auto hardware detection — detects M1/NVIDIA/CPU and picks the right model
• Tiered generation — tiny model for simple content, medium model for complex
• Finnish morphological validation — catches hallucinated inflections before they reach users
• Structured JSON output — Ollama's JSON mode ensures parseable responses every time
• Optional voikko integration — full spell/grammar checking if libvoikko is installed
• Zero cloud dependency — everything runs locally

Requirements

• Python 3.10+
• Ollama running locally (ollama serve)

Install

pip install fatg

With voikko support (recommended for production):

pip install fatg[voikko]
# macOS: brew install libvoikko
# Ubuntu: sudo apt install libvoikko-dev voikko-fi

Quick Start

import asyncio
from fatg import FATGEngine

async def main():
    # Auto-detects hardware, pulls model if needed
    engine = await FATGEngine.create()

    # See what hardware was detected
    print(engine.hardware)
    # Backend: apple_silicon | RAM: 16.0GB | Recommended: qwen2.5:7b (medium)

    # Generate a quest question
    q = await engine.generate_quest_question(
        target_word="kahvia",
        scenario="cafe_order",
        difficulty=0.1,
    )

    print(q.question_fi)
    # "Haluaisin kupillisen ...., kiitos."

    print(q.question_en)
    # "I would like a cup of ...., please."

    print(q.options)
    # ["kahvia", "teetä", "vettä", "maitoa"]  (shuffled)

    print(q.validation.score)
    # 0.9

asyncio.run(main())

KELA Boss Fight (LLM-generated questions from deck)

deck = [
    {"word_fi": "tukea"},
    {"word_fi": "hakemusta"},
    {"word_fi": "liitteitä"},
]

questions = await engine.generate_kela_questions(deck)
for q in questions:
    print(q.question_fi)
    print(q.options)

    temperature=0.7,
    max_retries=3,
    enable_finnish_validation=True,
)

engine = await FATGEngine.create(config=config)
