Ola! Curse and Coffee friends,

Coffee at the ready…

The take: OpenAI shipped GPT-5.1 with personality controls that let users tune the model's tone like a thermostat.
What happened: OpenAI launched GPT-5.1 on 12 November, adding adaptive reasoning and granular personality controls to ChatGPT for paid users.
Why it matters: Tone shapes influence. Giving users control over AI personality turns ChatGPT from a fixed tool into a platform that adapts how people think, decide, and communicate.
What to watch: The API rollout later this week, when developers decide whether to adopt personality customization as a standard feature across apps.
GPT-5.1 Instant is now “warmer,” “more conversational,” and (quoting OpenAI) “playful.”
