Libraries

How to use allenai/StdMoE_1b14b_1T_EmoAnnealed with Transformers:

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

pipe = pipeline("text-generation", model="allenai/StdMoE_1b14b_1T_EmoAnnealed", trust_remote_code=True)
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoModelForCausalLM
model = AutoModelForCausalLM.from_pretrained("allenai/StdMoE_1b14b_1T_EmoAnnealed", trust_remote_code=True, device_map="auto")

StdMoE_1b14b_1T_EmoAnnealed

The ablation checkpoint released alongside EMO: Pretraining Mixture of Experts for Emergent Modularity — referred to as EMO-anneal in Appendix B.4 / Table 3 of the paper.

1B-active / 14B-total parameter Mixture-of-Experts model (128 experts: 127 routed + 1 shared, k=8 active per token) pretrained on 1T tokens of the OLMoE pretraining mix with the standard MoE objective, then annealed for an additional 50B tokens under the EMO document-level expert pool constraint. Used to test whether modularity can be induced after pretraining instead of during it.

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "allenai/StdMoE_1b14b_1T_EmoAnnealed"
model = AutoModelForCausalLM.from_pretrained(model_id, trust_remote_code=True)
tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)

inputs = tokenizer(["Language modeling is "], return_tensors="pt", return_token_type_ids=False)
out = model.generate(**inputs, max_new_tokens=100, do_sample=True, temperature=1.0, top_p=0.7)
print(tokenizer.batch_decode(out, skip_special_tokens=True)[0])
