Libraries

How to use ArchSpace-Collection/OLMo3-1B-stage1 with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="ArchSpace-Collection/OLMo3-1B-stage1")

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("ArchSpace-Collection/OLMo3-1B-stage1")
model = AutoModelForCausalLM.from_pretrained("ArchSpace-Collection/OLMo3-1B-stage1", device_map="auto")
