grug-9b

numbers. grug measure, not guess

same harness both birds. same prompt. greedy. no cherry pick. eval code live in dataset repo (scripts/eval_grug.py).

how good

Table with columns: test, old bird, grug bird, change
test	old bird	grug bird	change
HumanEval pass@1	91.5%	79.3%	-12.2
MBPP pass@1	80.0%	78.0%	-2.0
agent replay: tool call valid	100%	88.9%	-11.1
agent replay: RIGHT tool picked	77.8%	88.9%	+11.1

how cheap

Table with columns: test, old bird tokens (think part), grug bird tokens (think part), change
test	old bird tokens (think part)	grug bird tokens (think part)	change
HumanEval	958 (570 think)	249 (36 think)	-74% (-94% think)
MBPP	594 (305 think)	148 (38 think)	-75% (-88% think)
agent replay	137 (99 think)	73 (14 think)	-47% (-85% think)

how fast

whole benchmark suite, same GPU, same everything:

Table with columns: old bird, grug bird
	old bird	grug bird
wall time	87.4 min	26.1 min

3.3x faster. tokens = time = money. grug bird leave money in pocket.

per SOLVED problem old bird spend ~1047 token. grug bird spend ~314. three grug answer for price of one old answer.

<think>Tuple field likely in fields.py. View file to find implementation.</think>
<think>Need exact line numbers for Tuple class. Use grep.</think>
<think>Understand how _bind_to_schema works in base Field class. Tuple likely
missing override that binds inner fields.</think>

real hypothesis chain. no "Let me carefully analyze". grug already analyzing. grug just do.

honest part. grug always honest

HumanEval drop 12 point. on hardest problem, big thinking was doing real work. grug bird trade some hard-problem muscle for 4x cheaper everything. if that trade bad for your cave, use old bird there
MBPP basically same. agent tool-choosing BETTER (+11). grug style maybe help bird pick right club
tool-call format valid 100 -> 88.9. sometimes grug bird talk when should poke tool
fix ideas grug not try yet: mix 10-20% long-think example in data, or second epoch

how use

python
from transformers import AutoModelForImageTextToText, AutoTokenizer
import torch

model = AutoModelForImageTextToText.from_pretrained(
    "ProCreations/grug-9b", dtype=torch.bfloat16, device_map="auto")
tokenizer = AutoTokenizer.from_pretrained("ProCreations/grug-9b")

messages = [{"role": "user", "content": "Write a function that checks if a number is prime."}]
inputs = tokenizer.apply_chat_template(messages, add_generation_prompt=True,
                                       return_tensors="pt").to(model.device)
out = model.generate(inputs, max_new_tokens=512, do_sample=False)
print(tokenizer.decode(out[0][inputs.shape[1]:], skip_special_tokens=True))

need transformers >= 5.8 (qwen3_5 architecture). thinking come in <think> tag. tool calling use same XML <tool_call><function=...> format as base bird. vision tower still inside, untouched, frozen during tune.

grug done. model think small. work same-ish. much cheap. go build.
