Claude Fable 5 can now run Grok 4.5 for you — and it's making workflows up to 90% cheaper. 🧠 Grok 4.5 dropped yesterday: 33% cheaper than Sonnet, 70% cheaper than Opus, and genuinely competitive with both on benchmarks — sometimes winning outright. It's a free, open-source plugin called fable-advisor. I installed it myself. Fable becomes the architect — writes the spec, judges every diff, never types the code. Grok 4.5 does the actual writing through the real Grok CLI, and every diff still gets verified before it's accepted. #claudecode #fable5 #grok #aitools #vibecoding
