Swift-1.5-Qwen3.8-27B-Uncensored-MTP VAL-APEX-I NanoPlus V3 GGUF

Independently computed on NVIDIA RTX PRO 6000 Ada hardware clusters. If this handcrafted release saves you VRAM and runs faster on your GPU, consider fueling the community compute fund on Ko-fi.

Uncensored Frontier 27B Reasoning MoE with Intact Vision, Multilingual Syntax Preservation, and Native MTP Self-Speculation

Official VAL-APEX-I NanoPlus V3 quantization of ajgazin/Swift-1.5-Qwen3.8-27B-Uncensored-MTP. This edition quantizes the uncensored foundation model built on UkisAI's Swift-1.5 reasoning fine-tune of Qwen3.8-27B.

• Multilingual Stability Guaranteed: Unlike models whose refusal abliteration damages foreign-language syntax, this base preserves French, Spanish, German, and Chinese grammar and agreement markers.
• Native MTP Speculative Head Included: Features the built-in Multi-Token Prediction auxiliary head (blk.64.*, 15 tensors), enabling fast speculative decoding directly in llama.cpp without an external draft model.
• Multimodal Optical Vision: Retains the high-precision vision encoder (mmproj-Q8_0.gguf) for visual and document reasoning.
• ISTA-DASLab Calibrated: Quantized with the official ISTA-DASLab importance matrix (imatrix-qwen3.8-27b.gguf) computed across diverse tokens to safeguard critical routing and projection weights.

VAL-APEX-I stands for:
Vector-calibrated Asymmetric Layer-wise Outlier-preserving Recurrent-aware Unified Matrix-quantization

ULTRA-COMPACT 11.08GB BUILD

This V3 release uses the asymmetric VAL-APEX-I per-tensor allocation with an actual 11.08 GB file size and 2.85 whole-file BPW. Its empirical WikiText-2 PPL is 6.9102, providing a lightweight footprint that fits comfortably into smaller VRAM envelopes while beating standard baselines like GSQ-RCO IQ3_S.

Size & Quality Metrics

The NanoPlus V3 file is 11.08 GB, approximately 0.72 GB smaller than GSQ-RCO IQ3_S, with 2.26% lower reported WikiText-2 PPL (6.9102 vs 7.07). MiniPlus V3 reaches 5.70% lower reported PPL (6.6669 vs 7.07) at 14.28 GB.

Perplexity Dynamics & Swift Alignment Impact

WikiText-2 measures raw next-token cross-entropy against encyclopedic Wikipedia prose. The Swift-1.5 fine-tuning process by UkisAI introduces deliberate architectural and distribution shifts:

1. Reasoning Density and Logit Compression: Swift-1.5 focuses probability mass on concise, dense chain-of-thought pathways (<think>) and direct reasoning outputs, stripping verbose filler tokens. This purposeful shift away from general Wikipedia text distribution naturally yields a slightly higher raw perplexity score on WikiText-2 (e.g. 6.66 vs 6.13 on raw base) without representing any degradation in actual intelligence or reasoning capability.
2. Speculative Decoding Efficiency: The true efficiency dividend of Swift-1.5 lies in inference throughput, realized through the integrated Multi-Token Prediction (MTP) head (blk.64.*, 844M parameters). In runtime, this yields substantial generation speedups via high speculative acceptance rates rather than static single-token prediction loss on historical corpora.

Tensor Precision Map

x is the number of tensors in each format. Counts were read from the released GGUF headers; the GSQ-RCO column uses its published tensor allocation.

Both V3 files contain 866 tensors: 851 main-model tensors plus 15 tensors in the additional MTP head. The 64 main layers are 48 Gated DeltaNet + 16 full-attention; blk.64.* is the MTP head, not a seventeenth main full-attention layer.

Fallback exceptions: blk.0.attn_gate.weight, blk.0.attn_qkv.weight, blk.0.ssm_alpha.weight, blk.0.ssm_beta.weight and blk.0.ssm_out.weight are Q4_0 in both editions. In the MTP head, Q/K/V, MLP gate/up and nextn.eh_proj are Q4_0; MLP down is Q4_1, attention output is Q6_K, and the remaining seven tensors are F32.

V3 layer allocation: MiniPlus uses IQ3_S for MLP gate/up in layers 0-15 and 48-63, and IQ3_XXS in layers 16-47; every main MLP down tensor is IQ4_XS. NanoPlus uses IQ3_XXS for gate/up in layers 0-7 and 56-63, and IQ2_XXS in layers 8-55; MLP down is IQ4_XS in the outer 16 layers and IQ3_XXS in the other 48.

6. Native Chat Template & Reasoning

The native Qwen Jinja chat template is embedded in this GGUF. Use --jinja where supported and preserve the native formatting for messages, tool calls and thinking blocks. Reasoning controls depend on the backend's implementation of the template arguments.

7. Community Compute Fund & Priority Model Requests

All IsValorum quantizations will always remain completely free and open to the public without paywalls.

However, cloud GPU compute is expensive. If you find these builds valuable and would like to support the project or request a specific model architecture to be prioritized for the next MiniPlus/NanoPlus release, you can sponsor GPU compute time through Ko-fi:

(When supporting on Ko-fi, feel free to leave a note with your Hugging Face handle and the specific model you would like prioritized).
