0:00.0	Welcome to the Techmeme right home for Friday, February 28th, 2025. I'm Brian McCullough today. OpenAI has launched GPT 4.5, but they want you to know this is not a frontier model. It's a stepping stone.
0:14.7	Skype enters the Deadpool. Meme coins are okay by the SEC. Most criminality in crypto is now done with stable coins, and in the
0:22.1	weekend long-read suggestions, how the MTA is using pixel phones to do subway maintenance.
0:26.6	Here's what you miss today in the world of tech.
0:32.8	OpenAI has launched GPT 4.5, what it calls its most knowledgeable model yet into research preview,
0:38.8	initially warning it's not a frontier model and may perform below O1 or O3 mini. Quoting the
0:45.2	verge, GPT 4.5 will have better writing capabilities, improved world knowledge, and what
0:50.0	OpenAI calls a refined personality over previous models. OpenAI says interacting with GPT4.5 will feel
0:55.8	more natural, adding that the model is better at recognizing patterns and drawing connections,
0:59.9	making it ideal for writing, programming, and solving practical problems. However, OpenAI notes
1:04.6	it won't introduce enough new capabilities to be considered a frontier model. GPD4.5 is not a
1:10.0	frontier model, but it is OpenAI's
1:11.6	largest LLM improving on GPT4's computational efficiency by more than 10x. OpenAI said in a document
1:17.9	that leaked ahead of its announcement, it does not introduce seven net new frontier capabilities
1:22.8	compared to previous reasoning releases and its performances below that of 01-03 Mini and deep research on most
1:28.8	preparedness evaluations. It was previously reported that OpenAI was using its 01 reasoning model
1:33.5	codename Strawberry to train GPT 4.5 with synthetic data. Open AI says it has trained GPD4.5 using
1:39.9	new supervision techniques combined with traditional methods like supervised fine tuning and reinforcement learning from human feedback,
1:46.7	similar to those used for GPT4O, end quote.
1:50.0	Sam Altman further said OpenAI was forced to stagger GPT4.5's rollout because it is out of GPUs, quoting TechCrunch.
1:57.6	We've been growing a lot in our out of GPUs, Altman wrote.
2:00.7	We will add tens of
