LFM2.5 2.6B DSpark

LFM2.5 2.6B DSpark is a speculative-decoding draft model from Liquid AI that adapts DSpark to the LFM2.5 architecture. It serves as a drafter for the LiquidAI/LFM2.5-2.6B target model, intended to allow that model to run faster without degrading quality. It is distributed under the lfm1.0 license and has a text-generation pipeline. The model card describes use with SGLang and on-device Apple silicon via a Metal backend.

Freshness 71 out of 100. Repository age: 90 days old, Aug 10, 2026. Measures age, not quality.

What do these scores mean?

Two ways to compare models. Neither score measures answer quality, benchmark performance, or whether a model fits your machine.

Freshness · release age

A new release starts at 100. The score halves every 180 days: 100 × 2^(−age in days / 180). When the release date is unavailable, a repository date is a fallback—not proof of when the model was released. Missing dates stay unscored.

Popularity · adoption

Downloads over the past 30 days carry 80% of the score; lifetime likes carry 20%. Both use a logarithmic scale, capped at 10 million downloads and 100,000 likes. If likes are unavailable, downloads carry all the weight. Missing download statistics stay unscored.

round(80 × min(1, log10(1 + downloads) / 7) + 20 × min(1, log10(1 + likes) / 5))

Best for

  • Speculative decoding as a draft model for LiquidAI/LFM2.5-2.6B
  • Faster decoding of the target model in SGLang
  • On-device decoding on Apple silicon through the Metal backend
  • Text generation when paired with the LFM2.5-2.6B target model
  • Use within the LFM2.5-DSpark family of speculative-decoding draft models

Tradeoffs

  • It is a draft model for LiquidAI/LFM2.5-2.6B and is not described as a standalone model.
  • Its license is lfm1.0, identified in the card as license: other.
  • The supplied material does not specify supported frameworks beyond SGLang or a Metal backend.
  • No independent testing or purchase recommendation is provided or implied.
  • Numerical hardware requirements, compatibility, or performance beyond the supplied figures should not be inferred.
