CODEX

OpenAI's May 8 macOS certificate rotation for ChatGPT, Codex, Codex CLI, and Atlas is not just a one-off update. It is a useful test of how your team governs AI developer tools.

Parallel agents can move faster than one agent, but only when tasks have clean ownership, review receipts, and a merge path that does not turn speed into cleanup work.

OpenAI's April 2026 Codex changelog shows a clear product shift: Codex is becoming a full agent workspace with goals, browser verification, automatic approval reviews, plugins, and tighter permission profiles.

OpenAI is moving Codex from a coding assistant into an enterprise agent platform. Here is what changed with Codex, Managed Agents, AWS, and the Responses API.

OpenAI's Codex Security agent reviews app code for vulns. Here is what it caught and missed on three real production repos.

GPT-5.5-Codex merges Codex and GPT-5 stacks. Here is what the unified model means for real coding agents - latency, costs, prompt rewrites.

What it actually takes to wire OpenAI Symphony into a Linear-driven Codex workflow - auth, runs, sandboxes, costs, and the gotchas nobody warned me about.

Opus 4.7 vs GPT-5.5, the new Codex CLI vs the Claude skills ecosystem. An opinionated April 2026 verdict on which terminal agent to reach for, by job.

From Claude Opus 4.7 and GPT-5.5 to Andrej-karpathy-skills and EvoMap - the AI dev tools actually shipping the last 30 days, with commands, links, and pricing.

A new study from nrehiew quantifies a problem every Claude Code, Cursor, and Codex user has felt: models making huge diffs for tiny fixes. Here is why it happens, why tests do not catch it, and what to do about it.

Set up Codex Chronicle on macOS, manage permissions, and understand privacy, security, and troubleshooting.

Hacker News keeps arguing about Claude Code, Codex, skills, MCP, and orchestration. Under the noise, the same four truths keep surfacing: workflows matter more than demos, verification is the bottleneck, skills beat prompts, and orchestration matters more than raw autonomy.

The coding-agent workflow is maturing past giant hand-written prompts. The winning pattern in 2026 is a control stack: project rules, reusable skills, bounded sub-agents, and deterministic tools around the model.

A deep analysis of what AI coding tools actually cost when you factor in usage patterns, hidden limits, and real-world workflows. Pricing tables, decision matrices, and recommendations for every developer profile.

12 AI coding tools across 4 architecture types, compared on pricing, strengths, weaknesses, and best use cases. The definitive comparison matrix for 2026.

Terminal agent, IDE agent, local-plus-cloud agent. Three architectures compared - how to decide which fits your workflow, or why you should use all three.

Cursor is editor-first. Codex is terminal, cloud, and PR-first. Here is when to use each for TypeScript projects.

Codex works from the terminal, cloud tasks, IDEs, GitHub, Slack, and Linear. Here is how to use it and how it compares to Claude Code.

OpenAI is drawing a line in the sand. GPT-5 Codex is not an API release.
