Qwen3.8-27B-TURBO-Fable-Cold-Fusion-735-882-Heretic-Uncensored-NM-DAU-fp16
FP16 conversion of DavidAU/Qwen3.8-27B-TURBO-Fable-Cold-Fusion-735-882-Heretic-Uncensored-NM-DAU, produced by bfsquish v0.1.0.
Intended use
Optimized for FP16 inference and fine-tuning on NVIDIA V100 (Volta) GPUs, which lack native BF16 Tensor Core support. The weights have been converted from BF16 to FP16 using the effective range_checked strategy (see below).

Conversion strategy
Direct upcast to FP32 followed by a range-checked FP16 cast. Values outside FP16's finite range are rejected instead of clipped, and rounding error is recorded in bfsquish_conversion.json. For BF16-trained weights that already fit inside FP16's range, this avoids graph-changing rotations and preserves the source checkpoint as closely as the target dtype permits.
Transform plan
v1 strategy applied: range_checked (no v2 plan bundle was produced for this conversion).
Enhanced chat template
Prompt rendering uses the selected third-party enhanced template; model weights are unchanged by this step. The standalone and embedded forms were smoke-rendered to the same prompt before publication.

vLLM warm-up profile
A version 1 advisory profile was generated at deployment/vllm/warmup-profile.v1.json after a PASS validation verdict (4 bounded cases). It is data-only and non-executable. Runtimes may ignore or override its hints; it does not select startup mode or failure policy and does not modify model weights. Its input scope is text-only: it warms text generation, not image/video/audio preprocessing, vision encoders, or multimodal fusion paths.
Numerical quality
| Metric | Value |
|---|---|
| Validation verdict | PASS |
| Validation method | generate |
| Max abs logit diff (vs. source) | 1.675378 |
| Min cosine similarity (vs. source) | 0.999265 |
| Token agreement rate | 99.80% |
| Inf/NaN scan | passed (no inf/nan) |
Validation notes
- generation agreement passed despite logit drift: token_agreement=99.80% (pass≥98.00%), min_cos=0.999265, max_diff=1.6754
