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.

SAM 3.1 is Meta's latest update to the Segment Anything Model family, released March 27 2026 as a drop-in replacement for SAM 3. The core innovation is object multiplexing: where the previous model required a separate processing pass for each tracked object, SAM 3.1 processes all tracked objects together in a single shared-memory pass, eliminating redundant computation across the decoder. The result is a doubling of throughput for videos with a medium number of objects—from 16 to 32 frames per second on a single H100 GPU—without sacrificing tracking accuracy. For applications like sports analytics, surveillance, or video editing that track 5–20 objects simultaneously, this makes real-time deployment on commodity cloud hardware feasible for the first time. SAM 3.1 inherits SAM 3's open-vocabulary segmentation capability (segmenting objects described by text prompts), which achieved 75–80% of human performance on the SA-CO benchmark covering 270K unique concepts. The model checkpoint is available on Hugging Face at `facebook/sam3.1`, and the codebase supports fine-tuning via the facebookresearch/sam3 repository. Meta released SAM 3.1 under a research license with commercial use provisions similar to its predecessors.

Reviewer scorecard

Builder
80/100 · ship

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.

80/100 · ship

The multiplexing change is a genuine architectural improvement, not just parameter tuning—processing all objects together means inference cost no longer scales linearly with object count. For video pipelines tracking 10+ objects this completely changes the cost calculus for real-time deployment.

Skeptic
45/100 · skip

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.

45/100 · skip

32 fps on a single H100 sounds impressive until you price H100 cloud time. The research license also creates uncertainty for commercial applications—Meta's licensing terms have quietly shifted in the past, and building a production pipeline on 'research license with commercial provisions' is asking for future legal headaches.

Futurist
80/100 · ship

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.

80/100 · ship

Segment Anything reaching real-time speeds on multi-object video unlocks an entire category of applications that were previously GPU-prohibitive: live sports analysis, real-time video editing, autonomous driving perception. SAM 3.1 is infrastructure for the next wave of vision applications.

Creator
80/100 · ship

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.

80/100 · ship

The open-vocabulary segmentation is what excites me most—being able to say 'segment the red jacket' rather than clicking a point means non-technical creative professionals can actually use this in video workflows. The speed improvement makes it viable in real-time editing tools.
