Particularly with so few "players" competing (retail). And whilst they might not do "price fixing" they will base their pricing on what their competitor sets so flavour of the week will be marginally more, new version and roles will swap with pricing increase.
I don't use them but my impression is that it's only really OpenAI and Anthropic. Google/Alphabet seem to be search focused, XAI and Facebook seem very 2nd rate and only really to encourage users to their Social Media. So not much competition with just the 2 main offerings.
IMO, any potential competition will simply be bought out.
Also, see Zwift. 😉
