There is clearly a very strong moat. OpenAI is close to 1 billion active users on ChatGPT while Claude barely have any non-business users. Even though Anthropic had better models at different times this year, I never stopped using ChatGPT and paying for Plus.
We just don't know who will win in which area yet. It doesn't mean there is no moat.
I don’t think it’s a question of moat. The usage limits on the chat interface with the more advanced Claud models are brutal. I feel like I can barely start a conversation before I get shutdown. However, I switched over to Gemini almost completely and barely ever checkin with ChatGPT these days.
I can't prove it (because they show no stats) but I feel like you get more Gemini Pro with a normal subscription than Opus with a Max plan.
Maybe the new more efficient models made it better for Claude users but that was my experience a couple months ago.
For professional usage though, Calude Code is so much ahead of Antigravity that it didn't even make sense to make a formal comparison. That, even when using the same model (Opus).
OpenAI has close to 1 billion users which are mostly free users and will switch provider the moment OpenAI start charging them or adding ads. Which they will, as OpenAI themselves said they are losing money even with 200$ subs. So that amount of users is pretty meaningless.
Google and Microsoft have immense money printing machines. They can lose many billions of dollars for years and be fine as a business. OpenAI, not so much.
All of these have ads. And none of these have an equal value alternative. OpenAI, Claude, Deepseek, Mistral, Gemini, are mostly the same to a regular user.
Bing is mostly the same. Kagi is mostly the same. Yahoo, Yandex, etc. It's 2025. Hardly any difference. There were tens of search engines in the 90s and 2000s that were generally mostly the same. Yet, Google still won and owned nearly all search monetization.
Search was even easier to switch. At least ChatGPT has memory.
Most chat apps are the same as Whatsapp. All of them are free too.
"Ask ChaGPT" is the equivalent to "google it" in 2025.
No those are all significantly worse products, or at least were for a long time. I don't think OpenAI has anything close to a moat. They don't even have a short fence.
