# grug-27b-gguf

**2026-07-23: all rocks re-squeezed from v2.1 weights** (deep think on hard
problems, stuck-loop escape, stop discipline - full changelog on
[grug-27b](https://huggingface.co/ProCreations/grug-27b) card). re-download if
you grab rocks before. mmproj unchanged (vision tower untouched).

grug brain squeezed into small rock. run on your cave computer with llama.cpp.

this GGUF of [grug-27b](https://huggingface.co/ProCreations/grug-27b):
Qwen3.6-27B that think in dense grug-speak inside `<think>`, answer in normal
english. same reasoning depth, way fewer think token. full story on main
model card.

## 27b and 35b hunt same prey

both parent grug hunt HumanEval and sanitized MBPP. number below come from big
parent brain, NOT squeezed GGUF rock. grug not claim rock test it never get.
number show pass@1 percent. bold grug win that hunt.

| hunt | [grug-27b](https://huggingface.co/ProCreations/grug-27b) v2.1 | [grug-35b](https://huggingface.co/ProCreations/grug-35b) rebuilt |
|---|---:|---:|
| HumanEval (164) | **87.2** | 80.5 |
| MBPP sanitized (100) | 85.0 | **88.0** |

## rock sizes

| file | quant | size | grug opinion |
|---|---|---|---|
| grug-27b-Q8_0.gguf | Q8_0 | 28.6 GB | basically bf16. big rock. |
| grug-27b-Q6_K.gguf | Q6_K | 22.1 GB | very good rock |
| grug-27b-Q5_K_M.gguf | Q5_K_M | 19.2 GB | good rock |
| grug-27b-Q4_K_M.gguf | Q4_K_M | 16.5 GB | best size/smart trade. grug pick this. |
| grug-27b-Q3_K_M.gguf | Q3_K_M | 13.3 GB | small rock. smart mostly survive. |
| mmproj-grug-27b-f16.gguf | mmproj f16 | see repo | eye rock. give grug vision back. |

every rock load-tested with llama.cpp before upload. no missing-tensor
sickness (grug check twice now, learn from 9b).

## Q4 person? special rock exist

grug make QAT version of Q4_K_M: weights trained while feeling 4-bit rounding
rock before final squish. better Q4 quality, same grug brain:
[grug-27b-qat-q4-gguf](https://huggingface.co/ProCreations/grug-27b-qat-q4-gguf).
rocks here best for Q8/Q6/Q5 people.


## if rock act broken

single-token spam ("/" forever etc) = NOT the rock. hybrid DeltaNet brain
CANNOT survive llama.cpp context-shift: old builds shift on context overflow
and corrupt the recurrent state into token spam. fix:
- use RECENT llama.cpp (qwen3_5 support; new builds refuse instead of shift)
- agent frontends (OpenCode etc): set `-c 16384` or bigger
- still broken? re-download rock (verify size) + check backend
grug re-test rock after every report: loads clean, zero spam at proper config.

## how run

need recent llama.cpp (qwen3_5 arch support).

```bash
llama-server -m grug-27b-Q4_K_M.gguf -c 16384 --temp 0.6 --top-p 0.95 --top-k 20
```

- vision NOW work: pair any quant with `mmproj-grug-27b-f16.gguf`
  (`llama-server -m grug-27b-Q4_K_M.gguf --mmproj mmproj-grug-27b-f16.gguf`).
  MTP still not included.
- context: base support 262144, pick what your RAM allow
- thinking on by default, reasoning arrive inside `<think>...</think>`
- for agent frameworks (OpenCode etc): works with think-stripped history,
  grug trained for exactly that world
