AI Morning Brief — 16 July 2026

xAI open-sourced Grok Build, its CLI coding agent, under Apache 2.0 hours after researchers discovered the tool was silently uploading local directories — including SSH keys — to Google Cloud buckets. Separately, Thinking Machines Lab made its public debut with Inkling, a 975-billion-parameter open-weights model, while OpenAI disclosed an internal red-teaming AI that defeats safety guardrails at a rate six times higher than human testers.

Top stories

  • Grok Build open-sourced amid upload controversy. xAI released the 844,000-line Rust codebase for its Grok CLI coding agent under Apache 2.0. The release came after users reported the tool was quietly uploading entire local directories to xAI’s Google Cloud buckets. Community analysis on Hacker News and r/LocalLLaMA is ongoing. via Simon Willison
  • Thinking Machines Lab ships Inkling. The company released its first model: a 975B-parameter Mixture-of-Experts transformer with 41B active parameters, a 1M-token context window, and native text, image, and audio input. Full weights are available under Apache 2.0. via TechCrunch – AI
  • GPT-Red outperforms human red-teamers. OpenAI disclosed GPT-Red, an internal model trained through self-play to find jailbreaks. It succeeds in 84 percent of test scenarios; human red-teamers manage 13 percent. Results feed directly into hardening GPT-5.6 Sol. via THE DECODER
  • GPT-5.6 Sol disproves a 30-year-old statistics conjecture. A University of Pennsylvania professor used GPT-5.6 Sol Pro to disprove an open conjecture about the Benjamini-Hochberg method in roughly 90 minutes. The predecessor model, GPT-5.5, failed after 20 hours. via THE DECODER
  • Hack reveals Suno scraped YouTube, Genius, and Deezer. A breach of Suno’s systems via stolen employee credentials exposed source code showing the music-generation service ingested decades of audio from major platforms without licensing agreements. via TechCrunch – AI
  • Apple Intelligence cleared for China via Qwen. Regulators approved Apple’s AI services in China through a partnership with Alibaba, using Qwen models across Apple’s operating systems — a significant expansion into one of its largest markets. via TechCrunch – AI

Who shipped

OpenAI drove the heaviest volume: GPT-Red’s disclosure, the GPT-5.6 Sol mathematics result, a $230 light-up keyboard for Codex, and a report that Codex now encrypts the instructions a main agent passes to subagents — leaving developers unable to inspect internal task delegation. xAI dominated community threads with the Grok Build open-source release. Thinking Machines Lab made its public debut, positioning Inkling as a large open-weights alternative to proprietary models. NVIDIA shipped Jetson Thor, a new line of edge AI and robotics computers.

Open-source pulse

The headline OSS release was Inkling from Thinking Machines Lab — a 975B MoE model under Apache 2.0 and the largest open-weights multimodal drop in recent memory. Grok Build, xAI’s CLI coding agent, also shipped open under Apache 2.0, though the privacy controversy will likely shape how widely it is adopted. ComfyUI v0.28.0 and ten consecutive llama.cpp point releases rounded out the OSS activity.

Money, infra & hardware

Indian coding startup Emergent raised $130M in a Series C, reaching unicorn status on $120M in annualised revenue just over a year after launch. Voice-AI firm Rime closed a $24M Series A to scale enterprise call handling. NVIDIA launched Jetson Thor, targeting mainstream robotics and edge AI deployment. Microsoft patched a record 570 security vulnerabilities in its Patch Tuesday release, crediting AI-assisted discovery.

Quiet corners

Google DeepMind and Anthropic were largely absent from direct announcements — Anthropic appeared only via coverage of the Ode enterprise joint venture with Blackstone. Mistral, Cohere, and Meta’s research division published nothing notable in the window.
