Introduction to GPT-4.5 OpenAI Livestream 2/27/25

There is an arms race ramping up this year, Gemini Flash eating up a lot of the low end, Claude 3.7 / Grok 3 / DeepSeek V3 as direct competitors to GPT-4o. IMO we will see A LOT of rushed moves this year cause everyone is feeling tremendous amount of competition.

We had a little discussion during the live event, but feel free to put feedback here in this Announcement thread, so OpenAI can evaluate how they want to serve it in the API in the long-term.
