Muse 1.2 in play

Where it shines, and where it slips.

Strengths

  • Long stories: No drop in quality across an eight-chapter story test, 13th of 140 on EQ-Bench’s long-story board.
  • Narration: Avoids purple prose better than most models.
  • Speed: Quick for a model that always thinks before it writes.

Drawbacks

  • Pacing: Drifts toward gentle, tidy plots that end by stating a lesson.

Plans and context

What each plan gives Muse 1.2.

It is included on Ultra at $24.99 a month, and on Legendary.

Context is how much the storyteller reads before it writes: the latest scenes, plus the memories, recap, and lore cards the moment needs. Bigger plans give a model more of it, which helps most in long campaigns.

Outside the guide

How public boards rank Muse 1.2.

None of these boards tests roleplay, so the guide reads them beside its own notes from real stories rather than in their place.

A high rank on long stories tends to mean fewer slips late in a campaign; a high arena rank means people liked its prose in a blind vote.
