lfm25-encoder-agnews-smoke

LiquidAI/LFM2.5-Encoder-350M fine-tuned for single-label text classification on fancyzhx/ag_news.

• Labels (4): World, Sports, Business, Sci/Tech
• Date: 2026-07-28 16:37 UTC

This model uses a custom classification head (mean pooling over a backbone without a native sequence-classification class), so loading requires trust_remote_code=True. vLLM serving requires a standard architecture.

Evaluation

Metric	Value
accuracy	0.7575
f1_macro	0.7568

Usage

from transformers import AutoModelForSequenceClassification, AutoTokenizer

model = AutoModelForSequenceClassification.from_pretrained("davanstrien/lfm25-encoder-agnews-smoke", trust_remote_code=True)
tokenizer = AutoTokenizer.from_pretrained("davanstrien/lfm25-encoder-agnews-smoke", trust_remote_code=True)

inputs = tokenizer("your text here", return_tensors="pt", truncation=True)
print(model.config.id2label[model(**inputs).logits.argmax().item()])
