description: "Kimi K3 is a powerful rival to ChatGPT and Claude Fable 5. Its API costs are roughly half those of GPT. I read many comments from Facebook and news. Mixed opinions. Some critics point out that deploying it requires significant upfront investment.I disagreed. In my own opinions, the benefits outweigh this cost. For company or national security, owning your model ensures superior data protection and security. Closed-source alternatives, by comparison, leave businesses vulnerable to unpredictable price changes and vendor leverage.Model of story: To survive you need to own it and not depend on others."
