Open AI don't always have the best models (especially for programming) but they've consistently had the best product/user experience. And even in the model front, other companies seem to play catchup more than anything most of the time.
The best user experience for what?
The most practical use case for generative AI today is coding assistants, and if you look at that market, the best offerings are third-party IDEs that build on top of models they don't own. E.g. Cursor + Gemini 2.5.
On the model front, it used to be the case that other companies were playing catch-up with OpenAI. I was one of the people consistently pointing out that "better than GPT o1" on a bunch of benchmarks does not reliably translate to actual improvements when you try to use them. But this is no longer the case, either - Gemini 2.5 is really that good, and Claude is also beating them in some real world scenarios.
>The best user experience for what?
The app has more features than anyone else, often implemented the smoothest/best way. Image Input (which the gemini site still sucks at even though the model itself is very capable), Voice mode (which used to be much worse in gemini until recently), Advanced Voice mode (no-one else has really implemented this yet. Gemini recently enabled native audio-in but not out), Live Video, Image gen, Deep research etc were all things Open AI did first and did well. Video Input is only just starting to roll out to Gemini live but has been a Plus subscription staple for months now.
>The most practical use case for generative AI today is coding assistants
Chatgpt gets 500M+ weekly active users and was the 6th most visited in the world last month. I doubt coding assistance is gpt's most frequent use case. And Google has underperformed in coding until 2.5 pro.

No that's still the case. Playing catch-up doesn't mean the competitor never catches up or even briefly supersedes it. It means Open AI will in short order release something that beats everyone else or introduces some new thing that everyone tries to beat. Image Input, 'Omni'- modality, Reasoning etc. All things Open AI brought to the table first. Sure, 2.5-pro is great but it doesn't look like it will beat o3 which looks to be released in a matter of weeks.
so please enlighten us why OpenAI is doing so much better than Anthropic
At this point it's pretty much entirely the first mover advantage.
I don't think you understand what first mover advantage is
In a world of zero switching costs, there is no such thing as first mover advantage
Especially when several companies like (A121 Labs and Cohere) appeared well before Anthropic and aren't anywhere close to Open AI
