This is one of the reasons it is my daily go-to LLM.
It shows that the x.ai team is responsive and moves quickly.
x.ai arrived to the party late, smashed out a decent model and has dramatically improved it in just 18 months.
They have the talent, the infra, the funds and real-time access to X posts. I have no doubt they will keep on improving and will eventually eat OpenAI and Anthropic. Google is the only other big player who really is a threat.
