GLM-5.3F in play
Where it shines, and where it slips.
Strengths
- Pacing: Scored first of 70 models for keeping a story moving on RP-Bench.
- Narration: Ninth of 140 on EQ-Bench’s creative writing board, with especially strong dialogue.
- Long stories: Keeps characters steady from scene to scene, with up to 100K of story in view on Legendary.
Drawbacks
- Dark themes: Deflected about half of the explicit intimate scenes on RP-Bench.
- Long stories: Can lose small details planted earlier in a scene.
- Speed: Thinks before every reply, so it runs slower than its name suggests.
Plans and context
What each plan gives GLM-5.3F.
It is included from Plus at $7.99 a month, and free accounts can play it with their 25 premium replies a day.
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.
| Plan | Context | Price a month |
|---|---|---|
| Plus | 16K tokens | $7.99 |
| Pro | 32K tokens | $14.99 |
| Ultra | 64K tokens | $24.99 |
| Legendary | 100K tokens | $49.99 |
Outside the guide
How public boards rank GLM-5.3F.
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.
| Board | Rank | What it measures |
|---|---|---|
| EQ-Bench Creative Writing | 9 of 140 | Short stories from 32 prompts, compared in pairs by an AI judge (Claude Sonnet 4.6). |
| EQ-Bench Longform | 15 of 140 | A planned story eight chapters long, judged chapter by chapter and as a whole. A model that fades late loses ground. |
| Arena Creative Writing | 68 of 414 | Blind votes from people choosing the better of two answers to the same creative prompt. |
