Creative writing model bake-off: author prefers Muse Spark, says GPT-6 can't write paragraphs
sam_paech · x · 2026-09-07
Blogger sampaech ran a subjective creative-writing bake-off across GPT-6-Astra, Fable 5.1, Muse Spark 1.3, and Gemini 3.8 Flash.
His takeaways:
- Muse Spark 1.3 is his favorite: it simply does what you ask without imposing an obnoxious house style.
- Fable 5.1 has converged on its own flavor of "claudeslop" and can no longer write normally.
- GPT-6-Astra has "forgotten how to write in paragraphs."
He half-jokingly suggests reviving the old tradition of reading model rollouts with your own eyeballs instead of relying on benchmark scores.
