I'm skeptical. According to arena.ai, Fable 5 dominates almost every category: https://arena.ai/leaderboard Kimi K3 has an edge in WebDev but struggles to reach top 10 in many other categories.
1) it's substantially slower.
2) it's substantially more expensive.
3) it's code is considerably worse.
It's a joke when you consider what you get for what you pay for.
