Titans-Qwen2.5-1.5B

Titanesque version of Qwen/Qwen2.5-1.5B with parallel linearized attention (TPTT 😊) and PEFT.

The model was presented in the paper TPTT.

Model Details

• Architecture: TpttModel
• Base model: Qwen/Qwen2.5-1.5B
• LiZA config: operator=delta_rule, mag=0.5
• LoRA config: r=8, alpha=16, dropout=0.05

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained(
"ffurfaro/Titans-Qwen2.5-1.5B",
trust_remote_code=True
)
tokenizer = AutoTokenizer.from_pretrained("ffurfaro/Titans-Qwen2.5-1.5B")

prompt = "Your prompt here"
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=100)
print(tokenizer.decode(outputs, skip_special_tokens=True))
