gated-deltanet-nsa-1.4B-30B

gated-deltanet-nsa-1.4B-30B

Gated DeltaNet + native sparse attention (1.4B params, 30B tokens)

Overview

• Training: gated-deltanet-attn-0.4B-10B was trained on FineWeb-Edu, which is realeased under ODC-By v1.0
• Parameters: 1.4B
• Task: Language modeling
• Framework: HuggingFace, flash-linear-attention
• Output structure: [batch_size, sequence_length, num_logits]

Performance

Various; available in paper

Running Code

• Minimal code to instantiate the model and perform inference:

# Requires flash-linear-attention (https://github.com/fla-org/flash-linear-attention)
import fla
from transformers import AutoModelForCausalLM, AutoTokenizer
model = AutoModelForCausalLM.from_pretrained(path_to_model).cuda()
tokenizer = AutoTokenizer.from_pretrained(path_to_model).cuda()
input_ids = tokenizer("All human beings are", return_tensors="pt").input_ids
outputs = model.generate(input_ids, max_length=15)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
