A fully functional Kubernetes cluster with 1 million active nodes.

Pushing Kubernetes to 1M nodes isn’t just hardware—it's architectural judo. Networking flips to exclusive IPv6.Less chatter, more breathing room. etcd hits a wall.Write throughput stalls at scale, so they swap it out. Entermem_etcd, a Rust-built replacement pushing over 1M buffered writes per second.. read more

How to Allocate Kubernetes Resource Ownership

Resource ownership in Kubernetes isn’t just a nice-to-have anymore—it’s turning into table stakes. Teams are usingnamespaces, RBAC, labels, quotas, and admission controllersto draw clear lines around who owns what, how much they can use, and what rules they follow. Tools likeKyverno,LimitRanges, and.. read more

Hardened Images: crafted by humans, protected by AI

Docker just wired anAI guardrailstraight into its Hardened Image (DHI) pipeline. It scans upstream diffs, catches regressions before they ship, and stops bad logic in its tracks. Case in point: it flagged a logic bug that slipped past the usual coding copilots. A real fix landed upstream. Win for cu.. read more

Connect Codex to MCP Servers via MCP Toolkit

OpenAI Codex just leveled up. It now hooks into Docker’sModel Context Protocol (MCP) Toolkit, which means it can tap directly into 200+ infrastructure tools—likeNeo4j graph databases—as if they were built-in features. With MCP, Codex doesn’t just code. It runs containers, spins up data models, eats .. read more

Mirantis Launches Pelagia for Enhanced Ceph Management on Kubernetes

Rook Pelagia Kubernetes Ceph

Mirantis introduces Pelagia, an open source tool to streamline Ceph storage management on Kubernetes, advancing automation and integration with GitOps workflows.

GPT-5.4 is OpenAI’s latest frontier AI model designed to perform complex professional and technical work more reliably. It combines advances in reasoning, coding, tool use, and long-context understanding into a single system capable of handling multi-step workflows across software environments. The model builds on earlier GPT-5 releases while integrating the strong coding capabilities previously introduced with GPT-5.3-Codex.

One of the defining features of GPT-5.4 is its ability to operate as part of agent-style workflows. The model can interact with tools, APIs, and external systems to complete tasks that extend beyond simple text generation. It also introduces native computer-use capabilities, allowing AI agents to operate applications using keyboard and mouse commands, screenshots, and browser automation frameworks such as Playwright.

GPT-5.4 supports context windows of up to one million tokens, enabling it to process and reason over very large documents, long conversations, or complex project contexts. This makes it suitable for tasks such as analyzing codebases, generating technical documentation, working with large spreadsheets, or coordinating long-running workflows. The model also introduces a feature called tool search, which allows it to dynamically retrieve tool definitions only when needed. This reduces token usage and makes it more efficient to work with large ecosystems of tools, including environments with dozens of APIs or MCP servers.

In addition to improved reasoning and automation capabilities, GPT-5.4 focuses on real-world productivity tasks. It performs better at generating and editing spreadsheets, presentations, and documents, and it is designed to maintain stronger context across longer reasoning processes. The model also improves factual accuracy and reduces hallucinations compared with previous versions.

GPT-5.4 is available across OpenAI’s ecosystem, including ChatGPT, the OpenAI API, and Codex. A higher-performance variant, GPT-5.4 Pro, is also available for users and developers who require maximum performance for complex tasks such as advanced research, large-scale automation, and demanding engineering workflows. Together, these capabilities position GPT-5.4 as a model aimed not just at conversation, but at executing real work across software systems.
