Andrej Karpathy's loopy era frame explains why Codex is becoming less like a chatbot and more like an agent loop manager for real software work.

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.

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.

A deep comparison of Codex's new /goal loop and Claude managed agents outcomes, with practical workflow examples, control tradeoffs, and migration guidance for long-running tasks.

Configurable memory, sandbox-aware orchestration, Codex-like filesystem tools. Here is how the new Agents SDK actually behaves in prod.

Apps SDK extends MCP with UI. Here is how to ship a real Apps SDK app from scratch: logic, interface, deploy, distribution, and the gotchas that cost me a weekend.

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

GPT-5.4 ships state-of-the-art computer use, steerable thinking, and a million-token window. Here is the implementation guide for builders, with real OpenAI SDK code, the 272K pricing cliff, and where it actually beats 5.3 and 5.5 in production.

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.

GPT-5.5 and 5.5 Pro hit the API on April 24. Here is what changes for builders: pricing, agentic tasks, tool-use, and the real benchmarks I ran the day it dropped.

AgentKit gives you Agent Builder, Connector Registry, and ChatKit. I rebuilt my newsletter-research agent on it. Here is where the visual canvas wins and where I bailed back to code.

OpenAI shipped an open-weight PII redactor. Here is how to wire it into a real ingestion pipeline locally, fast, with zero leaks, and how it benchmarks against Presidio and a regex baseline.

OpenAI is sunsetting the Assistants API in 2026. Here is a tested migration plan to the Responses API - code, state, threads, tools, every cliff I hit, in order.

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.
