ctest-Qwen3-8B-speculator.dspark-fp8ablation-fp8 is a machine learning model from inference-optimization. Use it for the machine learning task on the model card, and read the license before you ship it in a product.
Test checkpoint — not a production release. Trained to validate the FP8-quantized hidden-states transfer backend added in vllm-project/speculators1028 (draft, reviving 491).

ctest: Qwen3-8B DSpark speculator — FP8 hidden-states ablation (fp8)
Test checkpoint — not a production release. Trained to validate the FP8-quantized hidden-states transfer backend added in vllm-project/speculators#1028 (draft, reviving #491).
- Verifier:
Qwen/Qwen3-8B - Algorithm: dspark
- Hidden-states precision during training: fp8 (
new FP8 backend, per-token float8_e4m3fn quantization) - Training data: 5K magpie + 5K ultrachat samples from
inference-optimization/Dataset-Qwen3-235B-Instruct
This is one of a matched pair (...-fp8ablation-bf16 / ...-fp8ablation-fp8) trained
identically except for the hidden-states transfer precision, to isolate the effect of
FP8 quantization on speculator quality. See the sibling repo for the other precision.
