In terms of moat, I think people underestimate how much of OpenAI's moat is based on operations and infrastructure rather than being purely based on model intelligence. As someone building on the API, it is by far the most reliable option out there currently. Claude Sonnet 3.5 is stronger on reasoning than gpt-4o but has a higher error rate, more errors conforming to a JSON schema, much lower rate limits, etc. These things are less important if you're just using the first-party chat interfaces but are very important if you're building on top of the APIs.
Given that Mistral, Llama, Claude, and even Gemini are competitive with (if not better than) OpenAI's flagships, I don't really think this is true.
Everyone building is comfortable with OpenAI's API, and have an account. Competing models can't just be as good, they need to be MUCH better to be worth switching.
Even as competitors build a sort of compatibility layer to be plug an play with OpenAI they will always be a step behind at best every time OpenAI releases a new feature.
This isn't to say it's only going to be an OpenAI market. Enterprise worlds move differently, such as those in G Cloud who will buy a few million $$ of Vertex expecting to "figure out that gemini stuff later". In that sense, Google has a moat with those slices of their customers.
But I believe that when people think OpenAI has no moat because "the models will be a commodity", I think that's (a) some wishful thinking about the models and (b) doesn't consider the sociological factors that matter a lot more than how powerful a model is or where it runs.
This is the exact dynamic that gives OpenAI a moat. And it certainly doesn't hurt them that they still produce SOTA models.
Asserting facts not in evidence, as they say.
Switching LLMs right now can be compared to switching electricity providers or mobile carriers - generally it's pretty low friction and provides immediate benefit (in the case of electricity and mobile, the benefit is cost).
You simply cannot compare it to an email provider.
I elaborated a little more here on why I think OpenAI has quite the moat: https://news.ycombinator.com/item?id=41526082
Now, having a large existing customer base and thus having an advantage in training data that feeds into an advantage in improving their products and acquiring new (and retaining existing customers) could, arguably, be a moat; that's a network effect, not merely inertia, and network effects can be a foundation of strong (though potentially unstable, if there is nothing else shoring them up) moats.
Branding and first mover is it, and it's not going to keep them ahead forever.
This argument can really only meet its tipping point when massive models no longer offer a gotta-have-it difference vs smaller models.
This assumes that openly developed (or at least weight-available) models are available for free, and continue being improved.
What push are you referring to? By whom?
