What recent history showed us is that neither of LLM providers is unique, people switch models easily, nobody cares about the name but about the optimal performance for a given task (which can vary a lot between use cases).

(For example, Mistral is my go to platform for quick answers, not necessarily precise or long. In the past, I'd use GPT 4o for this (slower than mistral but not that much), but once sama decided to mud the waters and put everything under one umbrella it makes no sense for that purpose.)
