🚨 Breaking (last 24h)

OpenAI GPT-5.5 Instant Rolls Out to ChatGPT — Sam Altman Calls It "So Good Damn"

OpenAI's GPT-5.5 Instant model is now the default in ChatGPT, representing what Sam Altman described as "a pretty big upgrade" that users who have been "thinking-model-only" should try. The model delivers substantial improvements in intelligence, image perception, and factuality, with a writing style that is "a bit plainer and more straightforward" according to OpenAI post-training lead Eric Mitchell.

Altman also signaled more is coming, posting "hey chat, we haven't forgotten about you 👀" — fueling speculation about additional ChatGPT upgrades beyond the instant model swap. Sam Altman on X

Greg Brockman: "GPT-5.5 Is Both Very Capable and Very Succinct"

OpenAI co-founder Greg Brockman highlighted GPT-5.5's dual strengths of capability and conciseness, while also announcing that GPT-5.5-Cyber is now in limited preview for defenders securing critical infrastructure. Brockman also positioned Codex as "a transformative tool for all work done with a computer, not just coding" — a significant expansion of OpenAI's narrative around its coding agent.
