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.

GLM-5V-Turbo is Z.ai's (the international brand of Zhipu AI) latest model — and the first in the GLM family built as a native multimodal agent from the ground up. Released April 1, 2026, it combines vision, video, and text input with agentic output: tool calling, task decomposition, and GUI interaction, all in a single model without vision bolted on as an afterthought. The architecture is built around a new visual encoder called CogViT, trained with reinforcement learning across 30+ task types, and supports a 200K context window with INT8 quantization for fast inference. The practical sweet spot is the "visual artifact → code" pipeline: screenshot-to-HTML, UI component extraction from design mockups, screen recording analysis, and front-end scaffolding from design assets. In early benchmarks, GLM-5V-Turbo outperforms Claude Opus 4.6 on several multimodal benchmarks. It integrates seamlessly with OpenClaw and Claude Code for the full loop — "understand the environment → plan actions → execute tasks" — and is available via the Z.ai API and OpenRouter. For developers building agentic pipelines that start with visual input, this may be the most capable model to benchmark in 2026.
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.”
“Screenshot-to-production-code is the workflow I've been waiting for. GLM-5V-Turbo's native multimodal architecture means it doesn't lose fidelity when switching between seeing the design and writing the implementation. The OpenClaw integration makes it plug into existing pipelines immediately.”
“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.”
“Benchmark claims from model providers deserve serious scrutiny. 'Beats Opus 4.6 on multimodal benchmarks' is a cherry-picked comparison — we need independent evaluations across diverse real-world tasks before making architectural decisions. Also, the Z.ai data residency story for enterprise is unclear.”
“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 model arms race is increasingly about multimodal-native architectures, not just bigger text models. GLM-5V-Turbo signals that Chinese frontier labs are now genuinely competing on architecture innovation, not just scale. Expect this to pressure OpenAI and Anthropic to ship stronger native vision-coding models.”
“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.”
“The GUI interaction capability is huge for creative tooling — a model that can look at a Figma file and generate the component code directly eliminates the translation layer that kills creative momentum. This is the most exciting vision-to-code model I've seen since GPT-4V.”
