If you search duckduckgo for "https://openai.com/blog/gpt-4-5-turbo/", it seems to show a result! Is this real?
OpenAI announces GPT-4.5 Turbo, a new model that surpasses GPT-4 Turbo in speed, accuracy and scalability. Learn how GPT-4.5 Turbo can generate natural language or code with a 256k context window and a knowledge cutoff of June 2024.
This will, in general, use my (or mods if disputed)'s judgement. But for example, ignoring countervailing concerns most likely:
Resolves YES if OpenAI or sam altman or similar make a statement confirming it, resolves NO if they explicitly deny it
Resolves YES if that doesn't happen and OpenAI releases gpt-4.5 and the blog post appears similar enough to what appeared on duckduckgo that it indicates the leak was real
Resolves NO if gpt-4.5 is released and the blog post is different
Resolves NO if gpt-4.5 isn't released after some (long, close date extended if it's still plausible GPT-4.5 is releasing) period of time
