Instructions to use UniversalComputingResearch/Atom3.4m with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use UniversalComputingResearch/Atom3.4m with Transformers:

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

pipe = pipeline("text-generation", model="UniversalComputingResearch/Atom3.4m", trust_remote_code=True)

# Load model directly
from transformers import AutoModelForCausalLM
model = AutoModelForCausalLM.from_pretrained("UniversalComputingResearch/Atom3.4m", trust_remote_code=True, dtype="auto")
