Gemini 3.1 Ultra is Google's most capable model to date, featuring a stable 2 million token context window — enough to process 1,500+ pages of text, hours of video, or an entire large codebase in a single session. Unlike prior Gemini versions that stitched modalities together, 3.1 Ultra was trained from the ground up to reason across text, image, audio, and video simultaneously without transcription intermediaries. It also ships with native sandboxed Python execution: write code, run it, observe the output, revise — all within a single API call. On benchmarks, Gemini 3.1 Ultra shows meaningful gains on ARC-AGI-3, GPQA Diamond, and SWE-Bench Pro, while its long-horizon planning and agentic capabilities are improved over 3.0. The 2M context window is particularly significant for enterprise use cases involving large document sets, video analysis, and extended software projects. Multimodal inputs include chart reading, diagram interpretation, and frame-by-frame video analysis. Available through the Gemini API and Google AI Ultra subscription, Gemini 3.1 Ultra positions Google squarely against OpenAI's GPT-5.5 and Anthropic's Claude Opus 4.7 at the frontier. The sandboxed code execution removes the need for third-party Code Interpreter plugins, and the model's native multimodal design means developers can pass raw audio or video without preprocessing.

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.
Reviewer scorecard
“The native sandboxed Python execution is a major unlock. Being able to write, run, and iterate on code within the same API call — without stitching together a Code Interpreter plugin — simplifies a lot of agentic workflows. The 2M context window makes whole-repo analysis actually practical rather than theoretically possible.”
“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.”
“We've seen frontier model releases every few months and the benchmark improvements are getting smaller. 'Trained natively multimodal' was also claimed for Gemini 1.5 and 2.0. The 2M context window is impressive but most applications don't need it, and the cost at that scale is non-trivial. GPT-5.5 and Claude Opus 4.7 are both serious competition.”
“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 2M context window that natively understands video is a qualitative leap for enterprise AI. Imagine analyzing an entire quarter of earnings calls, legal discovery sets, or a full feature film for post-production — all in one shot. The sandboxed execution loop is the building block for fully autonomous data science agents.”
“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.”
“Native audio and video understanding without transcription intermediaries is huge for content workflows. Passing raw video directly and getting intelligent analysis — not just captions — opens up automated editing assistants, content QA, and creative research tools that weren't practical before. Google finally has a model worth building creative tools on.”
“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.”
