OpenAI's official 'Introducing GPT-5.5' video — the keynote-style first-party launch.
What is it?
OpenAI's official launch video for GPT-5.5 on its YouTube channel. The first-party canonical introduction, with demos and the company's framing of what's new.
How does it work?
Standard OpenAI launch format — research and product staff walk through capability demos and high-level positioning, paired with the launch blog post on openai.com.
Why does it matter?
When the canonical version of a frontier launch ships from the lab itself, it's the source the rest of the news cycle reacts to. Worth watching once even if you've already seen the recap takes.
Who is it for?
Anyone who wants OpenAI's own framing of GPT-5.5 before reading the third-party reactions.
