LFM2.5 VL 3B DSpark

LFM2.5-VL-3B-DSpark is an experimental speculative-decoding draft model for the vision-language target model LiquidAI/LFM2.5-VL-3B. It is intended to enable faster decoding while preserving the target model's output. The source lists compatibility with LFM2.5-VL-3B and its GGUF counterpart, and describes draft model details such as 279.5M BF16 parameters, a specified backbone configuration, Markov and confidence heads, and a vocabulary of 128,000.

Freshness 90 out of 100. Repository age: 27 days old, Sep 18, 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-VL-3B
  • Faster decoding of vision-language tasks without changing target outputs under greedy decoding
  • Use with SGLang on a single H100, where the source reports faster decoding
  • Use with MLX-VLM on Apple silicon at block size 8
  • Use with llama.cpp via the LFM2.5-VL-3B-GGUF target and its corresponding GGUF drafter

Tradeoffs

  • Requires pairing with the corresponding target model, such as LFM2.5-VL-3B or its GGUF version
  • Experimental draft model intended for speculative decoding, not standalone use
  • On Apple silicon the drafter uses block size 8 rather than 9
  • Acceptance and speedup depend on hardware and runtime overhead
  • No broad general-purpose or cross-model use is established by the supplied facts
