 To load a specific model revision with HuggingFace, simply add the argument `revision`:
 ```bash
 import hf_olmo # pip install ai2-olmo
-olmo = AutoModelForCausalLM.from_pretrained("allenai/OLMo-7B", revision="step1000-tokens4B")
+olmo = AutoModelForCausalLM.from_pretrained("allenai/OLMo-7B-Twin-2T", revision="step1000-tokens4B")
 ```
 
 All revisions/branches are listed in the file `revisions.txt`. 
 Or, you can access all the revisions for the models via the following code snippet:
 ```python
 from huggingface_hub import list_repo_refs
-out = list_repo_refs("allenai/OLMo-7B")
+out = list_repo_refs("allenai/OLMo-7B-Twin-2T")
 branches = [b.name for b in out.branches]
 ```
 A few revisions were lost due to an error, but the vast majority are present.
