I think it’s mostly a marketing, branding thing. Most people haven’t heard of the Chinese AI companies and models, but everybody heard of OpenAI and Anthropic. The US companies have sales team, a constant media presence. It’s just a question of time for open models to gain market shares.

Just look at how OpenAI has lost market share over the past year

>Why do people continue to use them despite the existence of so many open weights models?

Because of the low prices lol.
