LFM2.5-8B-A1B-DSpark-5L
DSpark speculative-decoding draft model for LiquidAI/LFM2.5-8B-A1B: a Qwen3-style GQA block drafter (5 layers) with a low-rank Markov transition head (rank 256) and a confidence head. Block size 7 (anchor + 6 drafts), interleaved (GPT-J) RoPE.
The draft ships no vocab weights; the embedding and LM head are tied from the target at load time.
Usage (SGLang)
python -m sglang.launch_server \
--model-path LiquidAI/LFM2.5-8B-A1B \
--speculative-algorithm DSPARK \
--speculative-draft-model-path tugot17/LFM2.5-8B-A1B-DSpark-5L \
--speculative-draft-attention-backend flashinfer
Requires an SGLang build with DSpark and LFM2 support.
