You ask "does anyone believe this"? I decided to think about whether I believe OpenAI is "open, academic, capped-profit for a noble reason collective".
I'll list some pros/contras in no particular order:
CONTRA: I can't download ChatGPT and run it locally. Why not? Clearly they are hoarding it.
PRO: They genuinely overtrain toward responses that the model judges benefit humanity, to the point of failing at the task. I can't think of a specific example but everyone knows what I mean. It is a frustration to users and doesn't help their image. They seem to be overtraining this way out of the goodness of their hearts.
PRO: its non-profit or capped-profit structure would let it behave in the way it claims it is behaving. (By contrast, a for-profit public company in some sense has a fiduciary responsibility to maximize value for shareholders rather than benefit for humanity.)
PRO: ChatGPT is available for free and Dall-E gives some free credits.
CONTRA: Dall-E doesn't give enough free credits. It might have a longer wait time for free users but it shouldn't hard cap them at a certain number of free credits per month. For example perhaps free users could not be subject to any reasonable usage limits (a few hundred images per day should be fine) but could have to wait 1 extra minute for each one.
CON: its architecture isn't open, it doesn't share how it trained its models, it doesn't publish its datasets and parameters that would let other companies achieve the same results (reproduce their work and have their own version), its research is closed off and unavailable.
CON: the company is not directly applying AI to proactively solving social problems.
CON: (debatable) some users who are not sources of revenue have been banned. From experimentong with a chatbot (not any hard legal limits just things like exploring their sexuality with the chatbot. It's just a chatbot, it would make sense to exclude such conversations from further training data or feedback, keep male and female researchers at OpenAI from having to review unsavory conversations, or even warn or at most temporarily ban the user. An account closure is super extreme for natural forms of interaction that don't go near legal limits. It does not seem like an open company. Alternative viewpoint: on the other hand, we keep certain flamebait subjects out of HN. Perhaps having certain subjects banable is necessary for their open mission at a larger level - specifically, users will stop going there for sex since they associate it purely with productivity, similar to how we associate HN with intellectual curiosity, which is a result of very heavy moderation here and without which this place would not exist in its form?)
Overall based on the above considerations, I think that OpenAI is not "open" but if it started publishing downloadable models for anyone to run, I would feel differently.
