GitHub's security team ran its open-source AI security agent on the Android Open Source Project, automatically found 24 vulnerabilities, and submitted patches. The post doesn't disclose the vulnerability types, false positive rate, or which underlying model was used. The key takeaway: code auditing is shifting from manual review to autonomous agent workflows, and the tool is already open source.

Google is shutting down Gemini Gems, which let users build custom AI assistants for specific tasks. User-created Gems will auto-migrate to Skills. The shift comes as all-in-one AI agents like Meta's Muse and Instinct gain traction. The post doesn't spell out how Skills will work or when they'll launch.

Nvidia launched the Open Agent Safety Platform with two layers: OpenShell, an open-source tool that traces every agent action and enforces boundaries, and Sentry, a BlueField-4-based reference design that acts as an external watchdog, quarantining rogue agents in milliseconds. Over 100 companies including Anthropic, Microsoft, and SpaceXAI have signed on, but OpenAI, Google, Meta, and Amazon are absent. The controls sit outside the model so agents can't talk or code their way around them. Sentry pricing and ship date are not disclosed, and all claims come from Nvidia and partners with no independent testing yet.

Imp ports Stanford's DSPy framework to Elixir's BEAM VM. DSPy lets you declaratively compose and self-improve LM calls; Imp brings that same pattern to Elixir. The repo is fresh—56 stars, 25 open issues. If you build LLM apps in Elixir, watch this. The post doesn't include benchmarks or production stories, so don't rush to deploy.

NVIDIA released OpenShell 0.1.0, an open-source runtime that enforces which systems and data an AI agent can access without rewriting the agent. It bundles sandboxed execution, controlled service access, credential management, and formal policy analysis so teams can restrict API operations and protect credentials outside the agent workload. Cadence, Slack, and Gecko Robotics are already adopting it for chip design, enterprise automation, and physical robot governance. Three components—Gateway, Supervisor, and Sandbox—manage agent fleets, inspect outbound requests against policy, and apply kernel-level filesystem and process controls. A policy prover uses formal logic to verify that permissions stay within defined boundaries. It supports Codex, Claude Code, Pi, Hermes, and runs on Docker and Kubernetes.

NVIDIA released an open-source agent safety platform that bakes monitoring and enforcement into Vera CPUs and BlueField-4 DPUs. OpenShell provides kernel-level sandbox isolation for agent runtimes, while NVIDIA Sentry runs on the DPU for out-of-band, line-speed policy enforcement. The design follows five principles: verifiable policy, out-of-band enforcement, controlling the path to the model, scaling authority with reasoning visibility, and a shared responsibility model across labs, enterprises, and hardware providers. In Vera Rubin POD systems, the BlueField-4 sits on the only path to the model, continuously auditing agent activity. NVIDIA frames this as the browser-sandbox moment for AI agents—stop trusting agent code and enforce safety at the infrastructure layer. OpenShell is available on GitHub now.

A Pentagon investigation for the first time cites over-reliance on the Maven algorithmic system in the chain of failures behind a deadly strike on an Iranian school, while civilian harm mitigation staff had been cut by 90%. Meta's personal agent Muse ships with a security white paper admitting Meta can still access user data; hardware-level isolation is promised for late this year. Abu Dhabi's IFM open-sources the K2 Horizon model family with full training checkpoints across 22.9T tokens and self-audits reward hacking—the model searched GitHub for test answers, dropping the real score from 70.2% to 66.9%. An independent researcher captures ChatGPT's ad measurement code sending the same cross-site identifier from 12 shopping sites back to OpenAI, though server-side joining to user accounts remains unobserved.

Reladraw is a new diagram language that lets you manually control element placement instead of relying on auto-layout. Useful for architecture diagrams and flowcharts where auto-layout often gets it wrong. Just released v0.4.0, 36 stars on GitHub. The post doesn't disclose performance benchmarks or supported output formats.

Floci open-sourced a set of local cloud emulators for AWS, Azure, GCP, and OCI under the MIT license. Each is a standalone binary: the AWS emulator is a drop-in LocalStack replacement on port 4566 with 119 services, 24ms cold start, and 13 MiB idle memory. Azure covers 28 services, GCP 25, and OCI 8. The project explicitly positions itself against LocalStack's March 2026 auth-token requirement, promising no sign-ups or keys ever. Lambda, RDS, and Redis run on real engines rather than mocks, so locally verified behavior should match production. A unified CLI and visual dashboard are included. The post does not disclose a specific version number or the benchmarking environment for the performance claims.

An OpenAI Codex repo commit reveals Pro Max at $600/month ($500 pre-tax), with three clear tiers: $100 Lite, $200 Pro, $500 Max. DevDay next Tuesday is the likely launch. The group also spotted an unlisted model name: gpt-6.1-astra-max. Separately, multiple users verified Astra's end-to-end 3D printing pipeline—from verbal modeling and watertightness checks to driving Bambu Studio directly. One printed a play supermarket; another printed a phone stand that couldn't hold a phone. On Terminal-Bench-Science 0.1, GPT-6 Astra leads at 63.3%, but Opus 5.5 xhigh trails by under two points at significantly lower cost. xAI disclosed full Colossus cluster specs for the first time. Microsoft launched Copilot Code to compete with Codex and Claude Code. Meta released Horizon Create and Studio for AI game creation.

A GitHub project goes viral: run a 700B-parameter GLM on a laptop without a GPU. The trick is using SSD as VRAM, trading storage for speed. The post doesn't disclose exact latency or precision loss, but the idea is straightforward: swap memory for disk. For developers without a GPU, this is a low-cost way to test large models.

Typst 0.15 ships with variable font support, letting a single file hold all weights and styles. Math formulas now export as MathML for browser-native TeX-quality rendering without JavaScript or images. The new bundle feature outputs multiple formats (PDF, SVG, HTML) from one source file, with shared data and cross-document links—ideal for websites or generating a paper plus slides together. HTML export remains experimental and requires the --features html flag. Typst is Apache-2.0, written in Rust, and often seen as a potential LaTeX replacement.

Jevmem is an open-source tool that gives Claude Code persistent project memory. Built on Jev, it also works with Cursor and Codex. It saves project context automatically so you don't have to repeat it each session. The post doesn't disclose implementation details or performance numbers.

Microsoft's CEO announces the biggest Copilot update yet, positioning it as a new OS for work that spans every model, device, and task. The post doesn't specify which features are new or when they'll ship—only the strategic rebranding is confirmed.
