Liquid AI just shipped LFM2.5-VL, a 450M-parameter vision-language model engineered from the ground up for edge deployment. Unlike most VLMs that require a beefy GPU in the cloud, LFM2.5-VL targets devices like the Snapdragon 8 Elite, NVIDIA Jetson Orin, and AMD Ryzen AI — hitting sub-250ms latency on-device without any cloud round-trip. This model builds significantly on its predecessor with four new capabilities: bounding box prediction (81.28 on RefCOCO-M), multilingual support across 8 languages, function calling, and improved instruction following. Those aren't just benchmark checkboxes — bounding box prediction means you can run visual grounding and object detection pipelines on a phone or robot without any server involvement. Liquid AI is the MIT-spun startup behind Liquid Foundation Models (LFMs), a non-Transformer architecture that delivers competitive performance at a fraction of the memory footprint. LFM2.5-VL is available free on HuggingFace and through Liquid's LEAP inference platform. For builders targeting on-device AI — robotics, mobile, embedded — this is one of the most practical releases of the month.

pi-llm turns a stock Raspberry Pi 4 (4GB RAM) into a private local LLM server using 1-bit quantized Bonsai models (1.7B and 4B parameters, under 1GB each). It includes a web chat UI accessible across your home network and implements native tool calling for physical hardware control — LEDs, displays, servo motors, and GPIO peripherals. The setup requires no GPU and no cloud dependency. The Bonsai-8B model family (recently covered here) runs efficiently enough on Pi-class hardware that the tool calling loop — chat message → model decision → GPIO action → result back to model — completes in a few seconds on 1.7B parameters. The project is a clean demonstration of where sub-1GB quantized models are genuinely useful: edge AI applications where latency to a cloud API is unacceptable, privacy matters, and the task is constrained enough that a small model performs adequately. It ships with working examples for five hardware configurations.
Reviewer scorecard
“Sub-250ms on-device vision with function calling is the unlock for a huge class of apps that couldn't tolerate cloud latency — real-time AR overlays, offline field inspection, privacy-sensitive medical imaging. The bounding box support is icing; ship this.”
“The tool calling implementation on hardware GPIO is the genuinely novel part. Most Pi LLM projects just do chat — this one closes the loop so the model can actually actuate things based on conversation. The 1.7B model is fast enough that it doesn't feel like waiting, which changes the interaction model entirely.”
“450M parameters with 8-language support and benchmark-leading vision grounding sounds great until you try to fine-tune it for a domain-specific task. The LEAP platform is still invite-only and the open weights lack fine-tuning docs. Worth watching but not shipping to prod yet.”
“A 1.7B model doing hardware control is a liability waiting to happen. The model hallucinates — what happens when it hallucinates a servo command? The project has no safety layer, no command confirmation, and no rate limiting on tool calls. Cool demo, genuinely dangerous in any real deployment.”
“The race to run capable VLMs on-device is the precursor to AI-native hardware. Liquid's non-Transformer architecture is showing that efficiency gains don't require the same trade-offs as quantization. This is what AI hardware of 2028 will be built around.”
“This is a preview of the embedded AI future. When every Pi-class device can run a local model with tool calling, the 'smart home' becomes genuinely conversational without routing everything through a cloud API. Pi-llm is early and rough but it's pointing at something real: private, offline, embodied AI agents.”
“On-device vision that can call functions means camera-native apps that don't phone home. Think real-time style transfer, offline image tagging, or AR creative tools that actually work on a plane. The creator tooling implications are underrated.”
“The creative applications here are underrated — conversational LED lighting, AI-triggered displays for studio ambiance, physical generative art installations that respond to natural language. The fact that it runs offline matters enormously for gallery or installation contexts where cloud reliability is a risk.”
