## Summary

Liquid AI announced **LFM2.5-VL-DSpark**, a draft model for its **LFM2.5-VL-3B** vision-language model. The model uses speculative decoding to speed up inference by up to **3.13x on-device** and **2.66x on H100 GPUs**, with end-to-end gains of **2.62x and 2.27x**, respectively. It adds **280M parameters** (8.9% increase) but maintains output quality, according to the company’s benchmarks across tasks like VQA, captioning, and multi-turn conversation.

The model supports **day-one integration** with **llama.cpp, MLX-VLM, and SGLang**, targeting edge and GPU deployments. Liquid AI emphasizes its open-weight approach, allowing unrestricted fine-tuning and deployment. The release aligns with the lab’s goal of AI running across devices, from base models to specialized variants like audio and vision.

## Key points

- LFM2.5-VL-DSpark speeds up vision-language model inference by up to 3.13x on-device and 2.66x on H100 GPUs
- Adds 280M parameters (8.9% increase) to LFM2.5-VL-3B with no output quality trade-off, per Liquid AI
- Supports day-one integration with llama.cpp, MLX-VLM, and SGLang for edge and GPU deployment

## Why it matters

Faster vision-language model inference reduces latency for applications like real-time captioning and multi-modal reasoning, critical for edge devices and latency-sensitive workflows.
