I Tested Opus 5 vs. Fable 5. What You Need to Know.

Nate Herk | AI Automation

Summary

El autor realiza una comparativa exhaustiva entre los modelos Claude Opus 5 y Fable 5, analizando su desempeño en tareas reales de trabajo de conocimiento, programación y generación de contenido. Aunque Opus destaca por ser más económico y eficiente en la verificación de tareas, Fable suele mostrar una mayor creatividad y rapidez en ciertas ejecuciones. La conclusión principal es que la elección depende del flujo de trabajo, sugiriendo el uso de modelos más ligeros como Sonnet cuando la capacidad de Opus o Fable sea innecesaria.

All right, so Claude Opus 5 is here and if you start to look at the benchmarks, it's really interesting because it shows us that for a lot of things that I care about, it's actually better than Fable and it is half the cost of Fable. Ultimately, Fable 5 is still Anthropic's most impressive and, you know, strongest model, but for a lot of these things, you know, I've realized when I'm doing knowledge work and when I'm building, you know, my videos or my research or whatever it is, Opus is more than enough power than what I need. And when you look at some of these charts, it's really interesting because it shows on things like the Frontier Bench and the Bench and this Coding Agent Index, that Opus is actually outperforming Fable and it's cheaper. And this really shocked me. So, obviously, I like to take all of this stuff with a grain of salt. It's fun to look at and it's good to look at, b…
