Libraries

How to use modrill/code-nothink-o7b-20260908 with Transformers:

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

pipe = pipeline("text-generation", model="modrill/code-nothink-o7b-20260908")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("modrill/code-nothink-o7b-20260908")
model = AutoModelForCausalLM.from_pretrained("modrill/code-nothink-o7b-20260908", device_map="auto")
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=256)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

code-nothink-o7b-20260908

Formerly Olmo-3-1025-7B-code-v4-nothink (HF redirect).

Arm ID: O7B-NOTHINK
Run ID: t30b2507-o7b-nothink-v4-tail151643

Merged full bf16 weights used for the official DEV256 NoThink evaluation. Tokenizer files in this repo are the eval-caliber bundle (olmo3-lcb-noprefill); they overlay any tokenizer files that were present in the merge directory.

Single-seed exploratory result, not a preregistered confirmatory claim.

Base model

Hugging Face: allenai/Olmo-3-1025-7B
Revision: a81bae42db3975be1671e27b9c9a56da1a9f980f (from RUN_IDENTITY.json / local snapshot /workspace/code-sft-infra/models/olmo-3-1025-7b)

Training

Method: LoRA r64 / α128 on seven projections (q_proj, k_proj, v_proj, o_proj, gate_proj, up_proj, down_proj), then merged into full-model bf16 safetensors
Data: NoThink code SFT (paired V4, physical 2-epoch concat)
Endpoint (score): step 140, 9,371,874 assistant tokens — endpoint-as-score, no checkpoint picking
Train seed 42; LR 1e-4; context 8192; AdamW; cosine by assistant-token dose
Host: local GPU box; eval tokenizer renderer olmo3-lcb-noprefill

Evaluation

Suite: official LiveCodeBench DEV256
Seed 3407, mode NoThink, max_model_len 8192, vLLM 0.28.0
Metric: sandbox pass@1 = passed / 256
This arm: 46/256 (18.0%), caps 107
Base (allenai/Olmo-3-1025-7B, same NoThink protocol): 20/256 (7.8%), caps 95
McNemar exact p = 6.9e-05

Inference notes

Use this repository's tokenizer and chat_template.jinja.
This chat template is the no-prefill <think> variant (olmo3-lcb-noprefill): do not prefill <think> at the start of the assistant turn.
Stop token ids: 100257 (<|endoftext|>) and 100265 (<|im_end|>).
Eval sampling used temperature 0.7, top_p 0.8, top_k 20.
