At the risk of this comment aging poorly, I am not convinced there is a magic GPT-5 around the corner, waiting to wallop anybody. I have a suspicion that we’re into diminishing returns with model scaling. All of the recent flagship releases (Gemini Ultra, Claude Opus, GPT-4 updates) have only advanced the frontier a little. Could OpenAI train something another 1-2 orders of magnitude bigger? Perhaps, but then it wouldn’t be economical to deploy it.
