Qwen3.8-27B-OBLITERATED-fp16

FP16 conversion of OBLITERATUS/Qwen3.8-27B-OBLITERATED at revision a58c3b53b3ce71551eafde2ed5ec8df48e0f4ff8, 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).

Numerical quality

Metric Value
Validation verdict PASS
Validation method generate
Max abs logit diff (vs. source) 0.157488
Min cosine similarity (vs. source) 0.999983
Token agreement rate 100.00%
Inf/NaN scan passed (no inf/nan)

Validation notes

  • generation agreement passed despite logit drift: token_agreement=100.00% (pass≥98.00%), min_cos=0.999983, max_diff=0.1575
