neural-txt 0.1.1

Structured NLP tasks powered by a fine-tuned small language model

neural-txt

Structured NLP tasks powered by a fine-tuned 135M parameter language model. Extract bullets, generate Q&A pairs, build knowledge graphs, and more — all running locally. Narrow vertical local intelligence that runs super cheaply in resource constrained envs.

Install

# Base (no inference backend)
pip install neural-txt

# With HuggingFace backend (torch)
pip install neural-txt[hf]

# With MLX backend (Apple Silicon)
pip install neural-txt[mlx]

Quick start

from neuraltxt import NeuralTxt

model = NeuralTxt(backend="mlx")  # or backend="hf"

passage = """
Transformers have revolutionized NLP by introducing the self-attention
mechanism. Unlike RNNs, transformers process all tokens in parallel,
leading to significant training speedups.
"""

# Extract key points
bullets = model.extract_bullets(passage)

# Generate question-answer pairs
pairs = model.generate_qa_pairs(passage)

# Extract knowledge graph triplets
triplets = model.extract_triplets(passage)

JSON mode

Every method supports json=True for guaranteed structured output via outlines:

# Returns a BulletsOutput pydantic model
bullets = model.extract_bullets(passage, json=True)
print(bullets.bullets)  # list[str]

# Returns a QAPairsOutput pydantic model
qa = model.generate_qa_pairs(passage, json=True)
for pair in qa.pairs:
    print(pair.question, pair.answer)

# Returns a TripletsOutput pydantic model
triplets = model.extract_triplets(passage, json=True)
for t in triplets.triplets:
    print(t.subject, t.relation, t.object)
