All content about Codex
Recent developments in Codex highlight enhancements in coding workflows, including the introduction of GPT-5.1-Codex-Max, which improves token efficiency and supports multi-context coding. Additionally, OpenAI has made GPT-5-Codex available to developers through API keys, facilitating integrations with IDEs like VS Code and enabling cloud delegation. These advancements reflect a growing focus on enhancing usability and safety in coding environments.
GPT‑5.1‑Codex‑Max adds compaction and token‑efficient reasoning to Codex, enabling coherent multi‑hour project coding across CLI, IDE, and cloud. It runs sandboxed by default with monitoring and safety controls.
Simon Willison shows how to run OpenAI’s Codex CLI on a Mac while offloading the actual AI model to a GPT-OSS 120B instance running on his DGX Spark via Tailscale and Ollama. It works—even for building a Space Invaders game—but it’s more of a fun hack than a daily driver.
Superpowers 3.3.0 runs SKILL.md agent workflows on OpenAI Codex with a Claude-to-Codex mapping, bootstrap, and helper scripts. Installer available — warns it downloads and executes code (remote execution risk).
A concise, practical guide to agent-driven development for large TypeScript/React codebases. Focuses on direct CLI interaction with gpt-5-codex agents, atomic commits, blast-radius edits, and lightweight planning.
Armin Ronacher describes a Go project where AI wrote ~90% of 40k lines—handling raw SQL, OpenAPI REST, SDKs, and Pulumi infra. He praises speed and iteration but warns human review is essential to avoid brittle systems.
OpenAI now offers GPT-5-Codex to developers via Codex API keys, at the same price as GPT-5 and available only through the Responses API. This enables IDE/editor integrations—see platform docs and changelog.
OpenAI’s Codex now integrates with VS Code, supports cloud delegation, and aligns with ChatGPT plans, with enterprise controls, data options, and documented limits for local and cloud tasks.
