specifically, the GPT-5.3 post explicitly leans into "interactive collaborator" langauge and steering mid execution
OpenAI post: "Much like a colleague, you can steer and interact with GPT-5.3-Codex while it’s working, without losing context."
OpenAI post: "Instead of waiting for a final output, you can interact in real time—ask questions, discuss approaches, and steer toward the solution"
Claude post: "Claude Opus 4.6 is designed for longer-running, agentic work — planning complex tasks more carefully and executing them with less back-and-forth from the user."
I don’t think there’s something deeply philosophical in here, especially as Claude Code is pushing stronger for asking more questions recently, introduced functionality to “chat about questions” while they’re asked, etc.
On further prompting it did the next step and terminated early again after printing how it would proceed.
It's most likely just a bug in GitHub Copilot, but it seems weird to me that they add models that clearly don't even work with their agentic harness.
