https://www.axios.com/2025/08/15/sam-altman-gpt5-launch-chat... quotes Sam Altman saying:

> Most of what we're building out at this point is the inference [...] We're profitable on inference. If we didn't pay for training, we'd be a very profitable company.

That might be the case, but inference times have only gone up since GPT-3 (GPT-5 is regularly 20+ seconds for me).

And by GPT-5 you mean through their API? Directly through Azure OpenAI services? or are you talking about ChatGPT set to using GPT-5.

All of these alternatives means different things when you say it takes +20 seconds for a full response.
