Libraries

How to use modrill/code-think-q8b-20260908 with Transformers:

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

pipe = pipeline("text-generation", model="modrill/code-think-q8b-20260908")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("modrill/code-think-q8b-20260908")
model = AutoModelForCausalLM.from_pretrained("modrill/code-think-q8b-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=40)

code-think-q8b-20260908

Research checkpoint: Qwen/Qwen3-8B-Base (49e3418fbbbca6ecbdf9608b4d22e5a407081db4) after V4 LoRA SFT on Qwen3-30B-A3B-Thinking-2507 traces, then merged to full weights.

This is a research checkpoint, not a product. Single-seed diagnostic numbers only. Do not treat DEV256 as a leaderboard claim.

Base, teacher, and data


Student	`Qwen/Qwen3-8B-Base` revision `49e3418fbbbca6ecbdf9608b4d22e5a407081db4`
Teacher	`Qwen/Qwen3-30B-A3B-Thinking-2507` traces (V4 paired think payload)
Problems	4715 unique problems (`source_1ep_rows`); physical 2-epoch concat = 9430 rows
Dose	32,436,894 assistant tokens / epoch; endpoint 64,873,788 assistant tokens (2 epochs)
Train seed	42

Recipe

LoRA r64 / α128, dropout 0.0, seven projections: q_proj, k_proj, v_proj, o_proj, gate_proj, up_proj, down_proj
Embeddings / lm_head frozen except two-sided trainable B-rows for 151643 (<|endoftext|>), 151667 (<think>), 151668 (</think>). Token ids from adapter/TOKEN_ROWS_META.json.
Assistant supervised tail: <|endoftext|> (151643)
LR 1e-4, AdamW (β 0.9/0.95), cosine over assistant-token dose, warmup 6% (3,892,427 / 64,873,788 tokens), weight decay 0.1
bf16, no packing, no truncation, context 32768
2 epochs, physical concat. Endpoint-only score; no checkpoint picking.

Merged weights are the 2-epoch endpoint (step-000921, 64,873,788 assistant tokens). LoRA + B-rows are under adapter/.

Evaluation (DEV256)

256-problem LiveCodeBench-derived dev split. Seed 3407, think mode, no <think> prefill, max generation ~32k, sandbox-verified pass@1. Temperature 0.6, top-p 0.95, top-k 20.

Cap = generations that hit the 32k length limit without closing </think>.

Model	pass@1	Cap	Notes
code-think-q8b-20260908	81/256	130	this repo; seed 3407; V4 think contract
Qwen3-8B-Base	55/256	—	old-contract historical bare-base number (not a same-contract V4 think-mode re-eval; a same-contract 8B-base think COMPLETE.json was not on disk)

Single seed. These are research checkpoints, not product scores.

For context, the same-family 4B base on the current V4 think contract is 63/256 (seed 3407), with a 5-seed band 55.2 ± 4.9 on an earlier bare-base protocol.

Usage

Merged full weights; no PEFT required at inference. Think mode: enable_thinking=True, do not prefill <think>.

from transformers import AutoModelForCausalLM, AutoTokenizer

repo = "modrill/code-think-q8b-20260908"
tokenizer = AutoTokenizer.from_pretrained(repo)
model = AutoModelForCausalLM.from_pretrained(
    repo, torch_dtype="bfloat16", device_map="auto"
)

system = (
    "You are an expert Python programmer. You will be given a question "
    "(problem specification) and will generate a correct Python program that "
    "matches the specification and passes all tests. You will NOT return "
    "anything except for the program."
)
messages = [
    {"role": "system", "content": system},
    {"role": "user", "content": problem_statement},
]
prompt = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True,
    enable_thinking=True,
)
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
output = model.generate(
    **inputs,
    max_new_tokens=32768,
    do_sample=True,
    temperature=0.6,
    top_p=0.95,
    top_k=20,
)
print(tokenizer.decode(output[0][inputs["input_ids"].shape[1]:], skip_special_tokens=False))

Stop ids used in the official eval: 151643 (<|endoftext|>), 151645 (<|im_end|>).
