Libraries

How to use sfanm/d24-sft-v2-olmo3-5b with Transformers:

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

pipe = pipeline("text-generation", model="sfanm/d24-sft-v2-olmo3-5b")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForMultimodalLM

tokenizer = AutoTokenizer.from_pretrained("sfanm/d24-sft-v2-olmo3-5b")
model = AutoModelForMultimodalLM.from_pretrained("sfanm/d24-sft-v2-olmo3-5b")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

d24 SFT - v2 base + OLMo-3 (5B chunked) midtrain (0.757B)

nanochat-style depth-24 decoder (24L x 1536 hidden x 12 heads, SwiGLU / RoPE / RMSNorm, tied embeddings, GPT-2 BPE vocab 50304, 0.757B params, 2048 ctx, LlamaForCausalLM).

Lineage: v2 pretrain (13.1B ClimbMix, WSD) -> OLMo-3 Dolmino (5B, chunked) midtrain (5.24B tok, 1 epoch, sfanm/d24-midtrain-olmo3-5b - the full OLMo-3 mix incl. reasoning traces + olmOCR PDFs, kept by chunking long docs) -> SFT (nanochat chat mix, 1 epoch, sfanm/d24-sft-mixture).

Eval (greedy, full sets): GSM8K 4.62% | MMLU 35.1% | ARC 37.0%. Beats the 2.3B-midtrain SFT (sfanm/d24-sft-v2-olmo3-2.3B: 3.79 / 32.8 / 35.6) on all three - the larger, fuller OLMo-3 mix improves both math and general capability.

Chat format: ChatML (<|im_start|>role\n...<|im_end|>); see chat_template.jinja.
