Speed (median): 165.5 tok/s
Thinking cost: 12,249 tokens · ≈75s · starved: none
ENVIRONMENT & LOAD (verified)
FrogNano-4B (Microsoft, qwen35 hybrid arch) Q8_0 on a 12 GB 3080 Ti — a 4B model fits with massive headroom: 6,489 / 12,288 MiB (~53% of the card), 16K context, single slot, fully on GPU. This is the opposite of the 27B-at-IQ2_S case — no spill, no PARALLEL tricks needed. Every number below was read from the live machine (nvidia-smi / lms ps) at load time.
| Model file actually loaded | frognano-4b-2609 — bartowski/FrogNano-4B-2609-GGUF Q8_0 (imatrix), 5.29 GB on disk, 4.93 GiB runtime (lms ps). Base: microsoft/FrogNano-4B-2609 (4.66B, Qwen3.5-4B, RL-trained coding agent, MIT, Sept 2026). |
| Context | 16,384 tokens (plenty of headroom for a 4B; could go much higher if needed) |
| Parallel slots | 1 |
| GPU layer split | All layers on GPU (4B — no CPU offload possible/needed) |
| GPU usage (measured, idle) | 6,489 / 12,288 MiB — only ~53% of the card; ~5.8 GiB headroom; 0% util, 12.26 W (idle sample) |
| Speed (median of 9 tests) | 165.5 tok/s — ~6x faster than the 27B models, expected for a 4B on the same GPU |
| Reasoning model | YES — emits reasoning_content (e.g. 199-4000 thinking tokens per test); the creative test starved at the 4000-token cap (0 content), consistent with an RL coding model that over-thinks open-ended writing. |
| Concurrent load | Qwen3.8-27B Q4_K_M reference model still running on the Arc B70 at (the benchmark's own session model) — different GPU, same box, shares CPU/RAM/PCIe. |
| Scoring | 6 objective tests auto-scored 10 (fib/constraints/json all passed; breakout/delta/fractal all have canvas+script). 5 subjective: reasoning 9, creative 1 (starved), breakout 9, delta 7, fractal 4 (JS bug: R/G/B never defined). Composite 7.7. |
| Known defect | fractal: line 207 'data[(y*w+x)*4]=255; R; G; B; A=255;' — R/G/B are bare no-op statements, never assigned, so pixel colors are never computed -> blank canvas. A genuine coding defect, not a harness issue. |
Observations
· [user] There is a new model I would like to try on the model zoo. 'frognano-4b coder' — download, load on LM Studio, run the AI test suite. (DONE — not in LM Studio's staff-picks zoo, so pulled the Q8_0 GGUF directly from Hugging Face (bartowski/FrogNano-4B-2609-GGUF) via lms get with the full URL. Loaded, ran all 9 tests, built the page.)
· [user] If you think there's a higher quality quant version that would fit, feel free to test that as well. (PENDING — Q8_0 is already the highest-quality quant (near-lossless). A second run at Q6_K (3.76 GB) is possible but lower quality; Q8_0 is the sensible primary.)
· [assistant] FrogNano is an RL coding agent (5-tool Leaf harness), so expect strong code/instruction tests and weak open-ended creative — exactly what showed up (creative starved, fractal has a real JS bug, but fib/constraints/json all perfect). (CONFIRMED by results.)
Still to verify
· Optional: run Q6_K (3.76 GB) as a second quant for comparison if desired — Q8_0 is the recommended primary.

The phrase "all but 9 die" means everything except for 9 died. Therefore, only those 9 sheep survived.

} creative.txt (547 bytes, full file beside this page)Vance stepped into the airlock. "Station stable," he muttered, checking seals. Earth hung vibrant and blue outside. He pulled the lever to open the door. Silence greeted him. No wind. Just a soft hum from within.
He looked at his hands. Smooth plastic, not grease. The door wasn't steel; it was glass. He touched the wall behind him. It felt like skin. His comms crackled. "Welcome home," the voice said gently. Vance froze. The station wasn't a ship. It was a bedroom. He woke up from a dream where he lived in space, but reality never left him.
