Codex-Spark Is OpenAI Splitting Coding Models Into Fast Hands and Slow Brains

Codex-Spark Is OpenAI Splitting Coding Models Into Fast Hands and Slow Brains

OpenAI’s most interesting coding-model launch this week is not another bigger brain for unattended pull requests. It is a smaller model designed to make the human stay in the loop because the loop finally feels fast enough. GPT-5.3-Codex-Spark is a research-preview variant of GPT-5.3-Codex aimed at real-time

GitHub’s Token Override Header Is a Small API Escape Hatch for a Very Real Agent-Runtime Dependency

GitHub’s Token Override Header Is a Small API Escape Hatch for a Very Real Agent-Runtime Dependency

The most dangerous assumptions in an agent runtime are rarely the cinematic ones. They are not “the model became sentient” or “the bot rewrote production.” They are usually a regex, a database column, a proxy, or a secret scanner that quietly assumed an access token would always look the same.

GPT-5.5 on Databricks Is a Reminder That Enterprise Agents Fail on PDFs Before They Fail on Philosophy

Enterprise agents do not usually fail first on philosophy. They fail on PDFs. They fail on scanned pages, legacy files, tables that lost their structure in 2014, invoices with one smudged digit, contracts with duplicated sections, permissions that hide the important appendix, and document sets where the answer depends on

Copilot Cloud Agent Gets an API, Which Means Agent Work Can Now Escape the UI on Purpose

Copilot Cloud Agent Gets an API, Which Means Agent Work Can Now Escape the UI on Purpose

GitHub just turned Copilot cloud agent from a button into an interface. That sounds like a small product-management distinction until you remember what APIs do: they remove human pacing from the loop. The new Agent tasks REST API, now in public preview for Copilot Business and Copilot Enterprise users, lets

Codex Hooks Going GA Makes Agent Policy Programmable — and Also Reviewable

Codex Hooks Going GA Makes Agent Policy Programmable — and Also Reviewable

Hooks are the kind of feature that rarely wins a launch-day popularity contest and then quietly becomes the thing enterprises cannot deploy without. OpenAI’s Codex Hooks going generally available is not glamorous. It is also one of the more important Codex platform moves this week, because it gives teams

The Best Local Coding-Agent Post Today Says the Quiet Part: The Model Is a Worker, Not the Authority

The best local coding-agent post today does not ask whether Qwen 3.6 is smart enough to write code. It asks the more useful question: what should the model be allowed to decide? Manolo Remiddi’s writeup on building a local coding-agent setup with Qwen 3.6, OpenCode, Hermes, and
