HRM-Text-1B-sft-code-LoRA

LoRA adapter for sapientinc/HRM-Text-1B.

sapientinc/HRM-Text-1B is a pretrained-only HRM text model. This adapter is the code post-training release built on top of it.

The release uses supervised LoRA post-training for coding tasks. It is the adapter artifact; the merged model is:

josephmayo/HRM-Text-1B-sft-code

Usage

from peft import PeftModel
from transformers import AutoModelForCausalLM, AutoTokenizer

base_id = "sapientinc/HRM-Text-1B"
adapter_id = "josephmayo/HRM-Text-1B-sft-code-LoRA"

tokenizer = AutoTokenizer.from_pretrained(adapter_id)
model = AutoModelForCausalLM.from_pretrained(base_id, trust_remote_code=True)
model = PeftModel.from_pretrained(model, adapter_id)
model.eval()

Notes

• This is an adapter, not a standalone merged model.
• This is the LoRA adapter. Use the merged model for standalone loading.
