About

Aion-1.0-Instruct is a pre-release small language model introduced in Microsoft Edge as a developer preview for early testing and feedback. It is designed to power Edge’s on-device Prompt and Writing Assistance APIs, giving web developers a faster, smaller, and more efficient model for AI-powered browser experiences. Microsoft previously used Phi-4-mini for these APIs, but its hardware requirements limited availability across devices. Aion-1.0-Instruct expands support to significantly more devices, including machines with less capable GPUs and, through CPU inference, devices without a GPU, while still delivering strong quality for a wide range of web use cases. The model is available in Edge Canary and Dev channels, allowing developers to evaluate it in real-world web scenarios, test API interoperability, and provide feedback before final optimizations. Aion-1.0-Instruct is meant to help developers build AI features directly into websites and browser extensions.

About

Liquid AI’s LFM2.5 is the next generation of on-device AI foundation models designed to deliver high-performance, efficient AI inference on edge devices such as phones, laptops, vehicles, IoT systems, and embedded hardware without relying on cloud compute. It extends the previous LFM2 architecture by significantly increasing the pretraining scale and reinforcement learning stages, yielding a family of hybrid models around 1.2 billion parameters that balance instruction following, reasoning, and multimodal capabilities for real-world agentic use cases. The LFM2.5 family includes Base (for fine-tuning and customization), Instruct (general-purpose instruction-tuned), Japanese-optimized, Vision-Language, and Audio-Language variants, all optimized for fast, on-device inference under tight memory constraints and available as open-weight models deployable via frameworks like llama.cpp, MLX, vLLM, and ONNX.
