Model Overview

s3nh/LFM2.5-350M-abliterated is a decensored version of the LiquidAI/LFM2.5-350M model, processed using Heretic v1.4.0. This 0.35 billion parameter instruction-tuned model is part of the LFM2.5 family, designed specifically for on-device deployment with a focus on efficiency and performance.

Key Differentiators

  • Decensored Capabilities: Achieves a refusal rate of 4/100, significantly lower than the original model's 89/100, making it more permissive.
  • Optimized for Edge Inference: Delivers fast inference speeds (e.g., 313 tok/s on AMD CPU, 188 tok/s on Snapdragon Gen4) and operates under 1GB of memory, with day-one support for llama.cpp, MLX, and vLLM.
  • Extended Training: Benefits from scaled training, extending pre-training from 10T to 28T tokens, and large-scale multi-stage reinforcement learning.
  • Tool Use Support: Features robust function calling capabilities, allowing for structured interaction with external tools.
  • Multilingual Support: Supports English, Arabic, Chinese, French, German, Japanese, Korean, Portuguese, and Spanish.

Performance Highlights

The model demonstrates strong performance in various benchmarks, often outperforming its predecessor, LFM2-350M, and other models in its size class on metrics like GPQA Diamond, IFEval, and CaseReportBench.
