Liquid AI Releases DSpark Draft Model, Speeding Decoding up to 3.18x
On August 21, Liquid AI released DSpark, a 300M-parameter draft model for the LFM2.5 family, introducing a speculative decoding path with measured throughput gains.
Confirmed
- DSpark is a draft model (300M parameters) for the LFM2.5 series using speculative decoding
- Mechanism: a lightweight draft model proposes candidate token blocks, validated by the target model in a single forward pass, trading minimal memory for significant decoding speedup with unchanged output quality
- Official benchmarks: up to 3.18x decoding speedup on H100 (MATH500); M4 Max was also tested though specific figures were not given in the posts
Why it matters
- Speculative decoding is a mainstream approach to cutting inference costs; DSpark demonstrates a viable path pairing a small draft model with the LFM2.5 main model
- Roughly tripling throughput with near-zero quality loss and minor extra memory has direct implications for real-world deployment costs of LFM2.5
