+ # StdMoE_1b14b_130B
17
+
18
+ The architecture-matched standard MoE baseline at the 130B-token ablation scale, released alongside [EMO: Pretraining Mixture of Experts for Emergent Modularity](https://arxiv.org/abs/2605.06663) — referred to as **Reg. MoE** (or "standard MoE") at 130B tokens in the paper. Not midtrained.
19
+
20
+ 1B-active / 14B-total parameter Mixture-of-Experts model (128 experts: 127 routed + 1 shared, k=8 active per token) pretrained on 130B tokens of the OLMoE pretraining mix with the standard MoE objective. Same architecture and data as `Emo_1b14b_130B`, differing only in the training objective.

22
+ ## Usage
23
+
24
+ ```python
25
+ from transformers import AutoModelForCausalLM, AutoTokenizer
26
+
27
+ model_id = "allenai/StdMoE_1b14b_130B"
28
+ model = AutoModelForCausalLM.from_pretrained(model_id, trust_remote_code=True)
29
+ tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
30
+
31
+ inputs = tokenizer(["Language modeling is "], return_tensors="pt", return_token_type_ids=False)
32
+ out = model.generate(**inputs, max_new_tokens=100, do_sample=True, temperature=1.0, top_p=0.7)
33
+ print(tokenizer.batch_decode(out, skip_special_tokens=True)[0])
