| This model is great at long horizon tasks, and Codex now has heartbeats, so it can keep checking on things. Give it your hardest problem that would take hours with verifiable constraints, you will see how good this is:) *I work at OAI. |

| Could be a great feature, can't wait to test! Tired of other models (looking at you Opus) constantly stuck mid-task lately. |

| ▲ | winrid 7 hours ago | parent | prev [-] | | Interesting, I just had opus convert a 35k loc java game to c++ overnight (root agent that orchestrated and delegated to sub agents) and woke up and it's done and works. What plan are you on? I'm starting to wonder if they're dynamically adjusting reasoning based on plan or something. | | |
| ▲ | gck1 6 hours ago | parent | next [-] | | I'm on max 5x and noticed this too. I don't use built-in subagents but rather full Claude session that orchestrates other full claude sessions. Worker agents that receive tasks now stop midway, they ask for permission to continue. My "heartbeat" is basically "status. One line" message sent to the orchestrator. Opus 4.6 worker agents never asked for permission to continue, and when heartbeat was sent to orchestrator, it just knew what to do (checked on subagents etc). Now it just says that it waits for me to confirm something. | |

| It's genuinely so great at long horizon tasks! GPT-5.5 solved many long-horizon frontier challenges, for the first time for an AI model we've tested, in our internal evals at Canva :) Congrats on the launch! |

| Sorry, what is "heartbeats", exactly? |
