xAI has expanded access to Grok Bot, its AI agent platform launched in beta on August 11, 2026, to include SuperGrok Plus, SuperGrok Heavy, Cursor Pro+, Cursor Ultra, and all Cursor Teams plans. Grok Bot functions as a digital teammate that can handle tasks autonomously across apps and inboxes, with browser and terminal access via a cloud computer. Users can run multiple Bots in parallel, set up routines, and message them via a text-thread interface on mobile or desktop.

Midjourney has shipped a major bug-fix update to alpha.midjourney.com, two weeks after launching a rough draft of significant platform changes. The update addresses dozens of issues across folders, upscale, gallery, and performance. Key fixes include collapsible folder groups in the sidebar, restored Upscale, Zoom, and Vary buttons for older V8.2 images, settings that no longer reset unexpectedly, reduced lag in prompt input and gallery scrolling, and corrected pill behavior. Moodboard and profile copy functions are also restored. The team warns new bugs may have been introduced.

Anthropic is expanding Claude Mythos 5 for cyber defense, making it available in Claude Security for Enterprise customers to scan codebases for vulnerabilities and suggest patches. The company is also launching the Defender Advantage Fund, providing $35 million in credits to organizations securing open-source software across three focus areas: patching live vulnerabilities, automating scanning, and pursuing ambitious security approaches. Anthropic is also expanding its Cyber Verification Program to include Mythos-class model access for vetted defenders.

Runway has launched Ruby, a new AI model that converts standard dynamic range (SDR) video to bit HDR, outputting in ProRes and EXR sequence formats. Ruby is compatible with any existing uploaded video or previously generated Runway output, supporting clips up to 30 seconds long. The tool is now available to get started on Runway's platform, offering filmmakers and creators a straightforward path to high-dynamic-range video without reshooting footage.

NVIDIA's Agentic Variation Operators (AVO) research project achieved a perfect 100% score on the ARC-AGI-3 benchmark, completing all 183 levels across 25 environments while using 12% fewer actions than competing system VISTA. AVO elevated Claude Opus 5 from a 30% standalone baseline to 100% by wrapping it in a general-purpose agent architecture featuring persistent memory, a supervisor module, and tool use. The same system previously outperformed FlashAttention-4 by 10.5% on NVIDIA DGX B200 hardware after seven days of autonomous GPU-kernel optimization.

DeepSeek has launched DeepSeek-V4-Flash-Vision-Exp, an experimental multimodal model, on its API platform. The model matches DeepSeek-V4-Flash on text capabilities including agents, reasoning, and world knowledge, while making a major leap on multimodal agent benchmarks, approaching Opus-4.8 performance. Images are billed at up to 384 tokens each at V4-Flash pricing. A new Files API lets users upload images once and reuse them via file_id. DeepSeek Harness 0.1.1 was also released with out-of-the-box support for the new model.

OpenCode has launched Ox Alpha, a stealth AI model available free for one week. The model features a 1 million token context window, multimodal capabilities, and zero data retention. OpenCode is offering generous rate limits with near-unlimited usage, backed by infrastructure capable of handling 100 trillion tokens per day. The free access period is intended to stress-test capacity and see how users engage with the model at scale.

OpenAI has added transparent background generation to its GPT-Image-2 API, now available in preview. The feature lets developers create reusable image assets that can be placed on any background, making it useful for product imagery, graphic design, website mockups, and marketing campaigns. OpenAI hinted that more transparency-related features are coming soon. The update expands GPT-Image-2's practical utility for commercial and creative workflows requiring flexible, compositable visual assets.

Anthropic has launched three production-ready tools on the Claude Platform: Computer Use, the Skills API, and the Files API. Computer Use now includes a browser use tool that reads page structure to target web elements more reliably than pixel-based clicking, and supports multi-action turns for faster task completion. The Skills API lets developers upload versioned instruction sets that run in Claude's sandbox. The Files API offers 1 TB storage per organization and 5x higher rate limits. Both APIs are also available via Microsoft Foundry.
