Llama-3_3-Nemotron-Super-49B-v1_5-fit24gib-GGUF
This repository carries one mixed-precision GGUF of
nvidia/Llama-3_3-Nemotron-Super-49B-v1_5,
solved to fit a 24 GiB VRAM budget.
vramfit measured each layer
group's quantization damage โ the shift in the model's output
distribution when that group quantizes โ then solved the bit allocation
under the budget and packed through llama.cpp's quantizer. The
fit24gib marker names the budget the solver targeted. This pack has no
single quantization scheme, and the budget is the claim. Built with
Llama.
Every measured number below sits beside its baseline counterpart. The card prints the losing numbers too.
Quality beside size
Held-out WikiText-2 test set, full 564 chunks. Tier 2 measures KL divergence (KLD) against the f16 base over two windows: the first 100 chunks and all 564. Lower is better for PPL and KLD. "Same top" is the share of tokens where the quantized model and the f16 base agree on the top token โ higher is better.
| Model | File size | PPL โ | KLD 100 โ | KLD 564 โ | Same top (564) โ |
|---|---|---|---|---|---|
| This pack | 20.36 GiB | 8.517 ยฑ 0.063 | 0.1538 | 0.2873 | 82.9 % |
| Q3_K_S (bartowski) | 20.45 GiB | 8.532 ยฑ 0.064 | 0.1584 | 0.2959 | 83.4 % |
| IQ3_XS (bartowski) | 19.47 GiB | 8.554 ยฑ 0.063 | 0.1982 | 0.3309 | 81.7 % |
| IQ3_XXS (bartowski) | 18.18 GiB | 8.723 ยฑ 0.065 | 0.2302 | 0.3665 | 80.1 % |
| UD-IQ3_XXS (unsloth) | 18.34 GiB | 8.697 ยฑ 0.065 | 0.1805 | 0.3439 | 82.0 % |
This pack beats every in-budget baseline on KLD 100 and KLD 564. On PPL it leads nominally everywhere โ a tie by the interval against Q3_K_S and IQ3_XS, a clear win over the two smallest. The size-matched Q3_K_S keeps one lead: top-token agreement, 83.4 % against 82.9 %. The i-quants are 0.9โ2.2 GiB smaller, and the size column is part of the comparison, not a footnote.
Against Q3_K_S on the full window, this pack is better on 369 of 564
chunks (65 %). The mean gap is 0.0086. A paired per-chunk test puts the
difference at 7.8ฯ. The pack is also the first spike-free profile among
this model's recorded packs. Its worst per-chunk excess over the
baseline anywhere in 564 chunks is +0.05. The three chunks where earlier
packs of this model spiked (347, 502, 137) read 0.126, 0.124, and 0.106.
analysis/kld564-paired-q3ks.json in this repository records this
comparison and the per-chunk KLD pairs that produce it.
What fit24gib means
The solver targeted a 24 GiB card serving 16k context at fp8 KV cache. The recipe records the arithmetic:
| Quantity | Bytes | GiB |
|---|---|---|
| VRAM ceiling | 25,769,803,776 | 24.00 |
| KV cache + runtime headroom | 3,791,650,816 | 3.53 |
| Weight budget | 21,978,152,960 | 20.47 |
| Predicted pack size | 21,957,337,301 | 20.45 |
| Real packed file | 21,860,214,272 | 20.36 |
The real file lands 112.48 MiB under the weight budget. Size prediction prices each GGUF type at its effective bits โ Q4_K spends 4.5 bits per weight, not 4. A 0.005 overhead fraction covers unquantized tensors and file metadata.
Measured 2026-09-04 on the reference RTX 4090 (issue #501): the pack does not load at 16k context with q8_0 KV cache while the desktop holds 2,341 MiB of the card. llama.cpp has no fp8 cache type, and q8_0 is its nearest substitute. llama.cpp b10326 put all 81 layers on the device (20,409.48 MiB) and then failed to allocate the KV cache. The largest context that served is 10,240 tokens, at 21,674.82 MiB of device buffers. The same day a headless RTX 4090 served the pack at 16,384 context. That card was a rented RunPod 4090 with 1 MiB resident, on the same llama.cpp release built with CUDA. Device buffers took 22,307.58 MiB, and nvidia-smi peaked at 22,762 MiB. The evidence page's twentieth data point records the ladder and the headless serve.
The recipe
The solver allocated 82 layer groups:
model.layers.0at 8-bit (Q8_0).- The other 81 groups at 3-bit (Q3_K), including the token embedding and the output head.
- 48 protected tensors hold
attn_vabove the group assignment: 47 floors at 5-bit (Q5_K), one at 4-bit (Q4_K,blk.3). The card uses the GGUF nameattn_vthroughout โ the recipe records the same tensors under their HF name,self_attn.v_proj.weight. - 4 imatrix exclusions:
blk.{1,2,3,5}.attn_v.weightquantize without their importance-matrix rows. Under this imatrix those rows collapse the weighted fit โ excluded, each tensor reconstructs 2.0โ4.3ร closer to f16 than its unprotected reference (RMSE 0.001641 vs 0.004755, 0.000574 vs 0.002229, 0.001136 vs 0.002303, 0.000501 vs 0.002178).
The pack ran base type Q3_K_S with --pure and 128 type overrides,
under the published importance matrix. A mandatory
reconstruction check compared all 48 protected tensors against an
unprotected reference pack: 48 of 48 reconstruct strictly closer to f16.
The recipe's predicted damage is 0.3905, summed from the sensitivity map's per-group measurements. Damage values are one scan's measurements on one measurement frame. Do not compare them across scans or across models.

The solver's trace
The solver is greedy damage-per-byte: at each step it demotes the group
with the least predicted damage per byte freed. It recorded all 162
demotion steps in the recipe, so the solve replays from the artifact.
The last step is the honest one. With 47 protection floors priced in,
the solver demoted model.layers.3 from 4-bit to 3-bit. That step freed
113,087,938 B at a predicted damage of 0.1129 โ 29 % of the recipe's
total, spent on one step. The measurements below did not punish that
trade.
Evaluation
Three tiers, one instrument: llama.cpp build b10172 (Vulkan), WikiText-2
test set held out from calibration, f16 KL references recorded once and
reused. Tier 3 ran lm-evaluation-harness 0.4.12 through an in-process
llama-cpp-python lane on the same build โ full evaluation splits, no
--limit, zero context truncations.
Tier 1 (perplexity) and tier 2 (whole-model KL) are the table above.
Tier 3 (task benchmarks) ran a slice fixed before any run: five tasks at leaderboard few-shot settings, on this pack and the size-matched Q3_K_S baseline. Deltas inside the combined standard error report as ties.
| Task (metric) | This pack | Q3_K_S baseline | ฮ | Combined ฯ | Verdict |

Five ties. The largest delta is 0.8ฯ (GSM8K, this pack nominally ahead). This pack trails nominally on Winogrande and ARC-Challenge โ both deficits print here with their error bars. The project fixed the slice before any run, so no result selected the tasks.
Read together: tier 2 ranks (the 7.8ฯ full-window KLD win over the size-matched baseline), tier 3 certifies (five ties at equal size).
Reproduce it
The repository ships the recipe, the importance matrix, the evals sidecar, and the run log beside the weights. Install the pack extra, then one command reproduces the pack from the base checkpoint:
pip install "vramfit[pack]"
vramfit pack recipe.json --llama-cpp <llama.cpp checkout> \
--model <checkpoint dir> --imatrix imatrix.gguf \
--out Llama-3_3-Nemotron-Super-49B-v1_5-fit24gib.gguf
The command converts the f16 base GGUF once, drives the recorded type
overrides and imatrix exclusions into llama-quantize, and runs the
reconstruction check itself. Expect all 48 protected tensors green.
The recipe is not a magic constant. It records the full solve: the
budget bytes, the 48 protections, the 4 exclusions, and the 162-step
trace. To solve for a different budget, run vramfit plan against the
published sensitivity map with your own --vram. The map is right
there:
Llama-3_3-Nemotron-Super-49B-v1_5-sensitivity-maps,
file sensitivity-64k-kquant-imx-no2-sized.json.
Guardrails and damage disclosure
This pack modifies no guardrail. Quantization compresses every weight tensor with one uniform lossy procedure. It does not bypass, disable, or circumvent the base model's safety training, which ships in these weights at lower precision.
Quantization can shift any model behavior, and guardrail behavior is no exception. The tables above are the measured bound on that shift: tier 2 measures whole-model KL divergence against the f16 base over the full held-out set, and tier 3 holds five statistical ties at equal size. The NVIDIA Open Model License conditions distribution on keeping "a substantially similar Guardrail appropriate for your use case" โ this card's damage disclosure is the evidence of that similarity.
One limit, stated plainly: damage measures the general output distribution on held-out WikiText-2 text, not guardrail behavior separately. Read this card as a damage disclosure, not a safety certificate. Deploy this pack with the same system-prompt and application-layer protections you would give the base model.
License
The base model ships under the NVIDIA Open Model License and is built on Llama 3.3, so Meta's Llama 3.3 Community License also applies. Both layers permit a quantized GGUF derivative on Hugging Face with attribution. This repository carries both license texts and both notice files. Built with Llama.

convert_hf_to_gguf.pyfor the f16 base, lm-evaluation-harness 0.4.12 with llama-cpp-python 0.3.34 for tier 3. - Every JSON artifact vramfit produced here carries the
vramfit_schemaenvelope key, and every run-log line carriesvramfit_runlog. Both keys renamed with the tool (#118). Task #121 re-uploaded those files on 2026-08-11. The key rename changed no measurement. The weights and the imatrix did not change, so the packed-file SHA-256 above still holds. A copy you downloaded before 2026-08-11 carries the old key, and vramfit rejects it. Download the file again.
Hashes prove identity, not quality. The evidence is the three tiers above, and every number on this card traces to the evals sidecar and the recipe published in this repository.
