Gemma 4 is Google's newest open model family — E2B, E4B, 26B, and 31B sizes — built on Gemini 3 architecture. For the first time, Google has released Gemma under Apache 2.0, making the models fully commercial-friendly with no Google-specific use restrictions. Every model in the family is natively multimodal from training: text, image, video, and audio inputs are all first-class. Context windows run 128K–256K tokens depending on size, and the models include built-in function calling, structured JSON output, and agentic workflow support. The E2B and E4B variants target on-device mobile and laptop deployment, with native audio understanding designed for always-on assistant scenarios. NVIDIA has already published optimized Gemma 4 containers for RTX hardware. The Apache 2.0 license removes a major adoption barrier that held back Gemma 3 in commercial products. Gemma 4 landed at #1 on Hacker News with 1,400+ points — the open-source model community's reaction was immediate and enthusiastic.

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
“Apache 2.0 means I can embed it in commercial products without legal review overhead. Native audio + 256K context on a 26B model that runs on a single A100 is a killer combo for production agent work. This is the open model I've been waiting for.”
“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.”
“Google has a history of releasing models and then quietly deprioritizing them once the PR cycle ends. Gemma 1 and 2 both got less maintenance than promised. The Apache license is great news, but trust has to be earned over time with consistent model updates.”
“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.”
“Native multimodal understanding — including audio — on models small enough for phones changes what ambient computing looks like. Gemma 4 on-device could be the model layer for a generation of always-on smart devices that don't need cloud inference.”
“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.”
“Image, video, and audio in one open model I can run locally? The creative tooling possibilities are enormous. I can build private multimodal workflows for client work without data leaving my machine. Apache 2.0 seals it — this is a 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.”
