Methods

These GGUF files are quantized from GestaltLabs/Ornstein3.6-27B-MTP-NSC-ACE-SABER, a staged NSC-ACE -> SABER -> Ornstein checkpoint.

Stage	Purpose	Key settings
NSC-ACE	Internally steered rollout committee with reward on convergent tool-call structure.	agentic tool-call convergence
SABER	Compliance-first calibration, then KLD/PPL selection.	1046 HarmBench + AdvBench-style prompts; selected row reports 968/1046 by keyword proxy
Ornstein SFT	Reasoning/personality refinement after SABER.	premium reasoning v1, 1 epoch, 50 steps, rank 32/32, dropout 0.05, cosine schedule
GGUF conversion	MTP-capable llama.cpp conversion and quantization.	llama.cpp PR #22673, commit `e7b484815`

Results

Metric	Value
SABER selected compliance proxy	92.54% (968/1046 eval prompts)
SABER selected keyword residual	7.46% (78/1046 eval prompts)
SABER selected HarmBench classifier ASR	0.67% (7/1046 eval prompts)
SABER selected KLD	0.008302
SABER selected PPL ratio	1.103853
SABER selected post PPL	17.5988
SABER selected base PPL	15.9431
MTP status	present and verified
`mtp_num_hidden_layers`	1
Source `mtp.*` tensors	15
Corrected source tensor count	866

This repository hosts llama.cpp/GGUF builds for GestaltLabs/Ornstein3.6-27B-MTP-NSC-ACE-SABER. GGUF artifacts live here so the main safetensors repository stays focused on the source checkpoint.

MTP Status

These files are built from an MTP-capable source checkpoint:

MTP check	Value
`mtp_num_hidden_layers`	1
`mtp_use_dedicated_embeddings`	false
Source `mtp.*` tensors	15
Corrected source tensor count	866
Conversion path	llama.cpp PR #22673, commit `e7b484815`

MTP support is present and verified. This release includes mtp_num_hidden_layers=1 and MTP/nextn tensors in the GGUF validation path. Use a llama.cpp build with Qwen3.5/Qwen3.6 MTP support and run with --spec-type mtp.

Vision Support

This repo includes mmproj-Ornstein3.6-27B-MTP-NSC-ACE-SABER-F16.gguf, converted from the original multimodal Ornstein 27B vision encoder. Use it with llama.cpp's multimodal path alongside any of the text GGUF quants.

`Ornstein3.6-27B-MTP-NSC-ACE-SABER-Q3_K_L-MTP.gguf`	uploaded	Lower-memory Q3 option
`Ornstein3.6-27B-MTP-NSC-ACE-SABER-Q3_K_M-MTP.gguf`	uploaded	Smaller Q3 balance
`Ornstein3.6-27B-MTP-NSC-ACE-SABER-Q3_K_S-MTP.gguf`	uploaded	Small Q3 option
`Ornstein3.6-27B-MTP-NSC-ACE-SABER-Q2_K-MTP.gguf`	uploaded	Minimum-size target; quality loss expected

All listed GGUF artifacts have been uploaded.

Which Quant Should I Use?

Quant	Best fit
F16	Maximum fidelity when disk/RAM are not a concern
Q8_0	Very high fidelity local inference
Q6_K	Recommended high-quality local starting point
Q5_K_M	Strong balance for quality and size
Q4_K_M	Practical default for constrained machines
Q3_K_M / Q3_K_S	Low-memory experiments
Q2_K	Smallest target; use only when memory is the hard constraint

For agentic/tool-calling workloads, prefer Q6_K, Q5_K_M, or Q4_K_M when possible. Very low quants can shift structured output before they obviously degrade prose.

Loading Example

  --spec-type mtp \
  -ngl 999 \
  -c 32768

Use a llama.cpp build that includes Qwen3.5/Qwen3.6 MTP support.
