Instructions to use AI4Chem/CHEMLLM-2b-1_5 with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use AI4Chem/CHEMLLM-2b-1_5 with Transformers:

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

pipe = pipeline("text-generation", model="AI4Chem/CHEMLLM-2b-1_5", trust_remote_code=True)
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoModel
model = AutoModel.from_pretrained("AI4Chem/CHEMLLM-2b-1_5", trust_remote_code=True, dtype="auto")
