A comparison discussion in the SillyTavern community about the GLM 5.3 role-playing (RP) experience, with direct reference value for "how to use prompts/presets to tune GLM 5.3 for RP."
The community generally believes that 5.2 is worse than 5.1 at RP ("I even think GLM 5 is more vivid and creative"), so directly comparing 5.3 with 5.2 is meaningless.
Strengths of 5.1: "grounded, good at multi-character interactions, follows instructions without needing a heavy resampling loop, and its positive bias can be redirected through prompting without becoming as cold/avoidant as 5.2."
Core question: Does 5.3 retain 5.1's "flavor"? (5.3 was not yet available on OpenRouter at the time, and the author was asking users with Coding/Lite plans.)
(+34, @dptgreg): "Needs more testing. Better than 5.0 and 5.2. Better than 5.1? Unsure."
(+48, @kuragekore): Strongly negative feedback — "It's cooked. Even when planning scenarios involving only consenting adult characters, it turns into an obnoxious moralist (moraloid), desperately pushing the content in a less 'degenerate' direction … This has suddenly been happening continuously since 5.3 was released; I have never seen such a severe failure on any GLM model." (+33 reply: "moraloid, I'm stealing that word")
(+3, @dptgreg, responding to the larger context window in 5.2): "Yes, 5.2's context-window tolerance and rule following are better than 5.1. Too bad it's not as creative." — Larger context vs. creativity is a trade-off in GLM 5.x.
(+1, @whattodoaboutit_): 5.2's larger context outperforms 5.1 for long-storyline RP (~20k context).
RP style differences are large and highly individual: 5.3 is better than 5.0/5.2, but there is still no definitive comparison with 5.1.
Presets are crucial: 5.3 performs significantly differently with different presets (see the "GLM 5.3 Community Consensus" post: the FF5.2 preset + GLM 5.3 produces "excellent results").
Censorship and moral constraints are stronger (Reddit community snapshot: "Heavier Censorship / 'Claude' Drift"): RP scenarios require explicit character settings and boundaries in the system prompt/preset, with a "gradual" approach when necessary.
Context vs. creativity trade-off: 5.3 continues the 5.x direction — greater context-window tolerance and stronger rule following, but some users feel it is "less free."
5.3 was not yet available on OpenRouter at the time, so the experience had to be accessed through Coding Plan/ZCode channels; note that Reddit also had reports of a "no-thinking fallback" (switching to instant/none mode after the quota is exhausted).
"Better than 5.0 and 5.2. Better than 5.1? Unsure." (+34)
