Gemma 4 is Google DeepMind's fourth-generation open model family, released April 2, 2026, under Apache 2.0. Four variants ship in the family: E2B and E4B edge models that run fully offline on phones, Raspberry Pi, and NVIDIA Jetson; a 26B Mixture-of-Experts model that activates only 3.8B parameters at inference; and a 31B Dense flagship. The 31B scores 1452 on the Arena AI text leaderboard (third among all open models), hits 89.2% on AIME 2026 math, and 85.2% on MMLU Pro — versus Gemma 3's 20.8% on AIME. All four model sizes accept text and image inputs. The edge models additionally handle native audio and video, making them the first on-device models with full multimodal coverage. Context windows reach 256K tokens on the large variants, enabling entire codebases or long documents in a single prompt. Native support for tool use, structured output, and agentic workflows is baked in from the start. For the open-source AI community, Gemma 4 is a watershed: a commercially permissive model that genuinely competes with closed-source alternatives on reasoning benchmarks. Gemma downloads crossed 400 million before this launch — Gemma 4's edge deployment story, combining on-device inference with frontier-class reasoning, looks set to make that number look small.

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, runs on a Pi, 256K context, beats proprietary models on AIME — this is the open-source AI stack I've been waiting for. The agentic workflow support baked in natively means I'm not bolting on separate tooling. Shipping today.”
“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.”
“The benchmark numbers are impressive on paper, but Gemma 3 was also hyped and underdelivered in production on complex multi-step tasks. The edge models are still unproven outside of Google's own hardware partnerships. Watch the community benchmarks before committing to a migration.”
“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.”
“On-device frontier-class intelligence with native audio and video is the inflection point for ambient AI. When a $35 Raspberry Pi can run a model that beats last year's GPT-4 on math, the entire economics of edge AI applications change overnight. This is the model that makes AI infrastructure costs asymptotically cheap.”
“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.”
“The document and PDF parsing, OCR, chart comprehension, and UI understanding built into every model size is huge for creative workflow automation. I can finally build tools that read design briefs, invoices, and mockups without needing a cloud API call. The offline capability means client data never leaves my machine.”
“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.”
