A big wow moment coming up is going to be GPT 5.* in Codex with Cerebras doing inference. The inference speed is going to be a big unlock, because many tasks are intrinsically serial.
It's going to feel literally like playing God, where you type in what you want and it happens ~instantly.
Speed is really important to me but also I would like higher weekly limits -- which means lower cost I suppose. Building out complex projects can take 6 months to a year on a Pro plan.
My trick is to attach the codebase as a txt file to 5-10 different GPT 5.2 Thinking chats, paste in the specs, and then get hard work done there, then just copy paste the final task list into codex to lower codex usage.
