Sam said on Lex's podcast that people should temper their expectations for GPT-5, not in that it will necessarily suck, but that they want to ramp up ability slowly over time rather than discrete large steps.
Yeah. Sam wants to productize $$$ what they have now rather than sink time and money training future models with uncertain outcomes. I suspect that difference in focus is what Ilya Sutskever means by wanting to “advance capabilities as fast as possible” in the in Safe Superintelligence Inc. announcement.
