The post reports sharply divided RP feedback: in a four-model SFW blind test, one user rated M3.1 Flash the worst, saying its output was full of clichés and felt like an AI assistant; another user, working with a specific preset, reported better multi-character interaction, continuity, and characterization. The latter user reported entering temperature=0.9, top_p=0.9, and reasoning=medium, but the post did not verify whether these client-side values actually took effect; they considered high drier and more prone to overthinking.
Tasks suitable for evaluation: Roleplay in SillyTavern, long-conversation continuity, multi-character interaction, writing style, and preliminary testing of reasoning levels.
Tasks unsuitable for extrapolation: General RP rankings, formal quality weighting, long-term stability, guarantees of no censorship, or performance across all providers; the post has no unified task, sample size, or scoring rules.
Applicable model version: MiniMax M3.1 Flash; the OpenRouter slug shown in the attached image is minimax/minimax-m3.1-flash:free. The post provides no more specific model snapshot.
Test environment or client: SillyTavern; the attached image is from the OpenRouter model page. Specific API configuration was only partially disclosed in one comment.
Reasoning level and parameters: One commenter used temperature=0.9, top_p=0.9, and reasoning=medium; they considered high drier and more prone to overthinking, and said a prompt that lowers reasoning might help. Other users' parameters were not specified.
The original poster only said that the model had previously been released under Space Bunny's stealth-model name and attached a screenshot of the OpenRouter model card. At the time, the screenshot showed minimax/minimax-m3.1-flash:free, 1M context, a single MiniMax provider, reasoning effort=All, and, in the page snapshot, 1.80 seconds of latency, 79 tps, and 100% uptime. These are page-snapshot values and should not be treated as permanent free access or fixed service metrics.
The comments did not use a unified experiment. heville explained that they had an AI agent run an SFW blind test with four models, then had themself and another unrelated model score it; the other feedback came from personal RP conversations. Probablynottoocool's experience used a closed beta preset that could not be shared publicly, so only the reported results and disclosed parameters can be reproduced; the complete preset cannot.
heville reported that M3.1 Flash ranked last in a four-model SFW blind test, both in their own scoring and in the scoring by another AI; the output contained many clichés and had a feeling of "folding like an AI assistant."
LordVulpius considered M3's RP quite good, but thought M3.1 had regressed substantially in RP; they only speculated that capabilities such as programming might have improved, without providing parameter or task records.
stopaskingforloginn considered the output dull, mechanical, and unremarkable, while saying that their own experience contained no censorship.
Eastern-Dream932 thought the model might be useful for some agentic workflows, but that it overthought during RP, producing results that were more mechanical and more "technically correct."
Probablynottoocool used a closed beta preset that could not be shared at the time and reported a different experience: the model proactively triggered lorebooks and created multi-character dynamics; compared with M3, the conversations were better, it could recall past events, maintain continuity, and weave world details, character goals, and subsequent plot developments together; it also handled layered characters well.
The same user also reported clear limitations: when the model seemed to be overused, quality varied widely across consecutive swipes; it was somewhat dry compared with more lively models; and excessive initiative could turn into forcing the plot forward. Their disclosed configuration was temperature=0.9, top_p=0.9, and reasoning=medium. They considered high drier and more prone to overthinking, and said a prompt that lowers reasoning might help.
| Source | Verifiable practical feedback | Environment and parameters |
|---|---|---|
| heville comment | In a four-model SFW blind test, M3.1 ranked last in both the user's own scoring and another AI's scoring; clichés, AI-assistant-like output | Blind test built by an AI agent; 4 models; otherwise unspecified |
| LordVulpius comment | Compared with M3, whose RP performance was considered good, M3.1 was judged to have regressed substantially | Unspecified |
| stopaskingforloginn comment | Dull, mechanical, and unremarkable; said their own experience contained no censorship | Unspecified |
| Probablynottoocool comment | Multi-character dynamics, lorebook triggering, continuity, and character goals performed well; quality varied, the style was dry, and initiative was excessive | Closed beta preset; temperature=0.9, top_p=0.9, reasoning=medium; preset undisclosed |
| Eastern-Dream932 comment | RP was poor; after overthinking, the output became more mechanical and more technically correct | Unspecified |
The attached image in the original post also showed the following OpenRouter page fields:
Model: MiniMax: MiniMax M3.1 Flash (free)
endpoint slug: minimax/minimax-m3.1-flash:free
context: 1.0M
provider: MiniMax; the page said there was only one provider, with OpenRouter forwarding requests directly without routing selection
page snapshot: reasoning effort=All, latency 1.80s, throughput 79 tps, uptime 100.00%
These fields came from the attached image visible on 2026-10-21 during collection, not from a shared test protocol used by the commenters. free only describes the endpoint status in that snapshot; it does not represent permanent free access.
The conclusion supported by this set of community opinions is that M3.1 Flash produces substantially different experiences in SillyTavern RP. Without a specific preset, some users found the output dull, mechanical, and assistant-like, or felt that overthinking hurt RP; another user observed strong multi-character interaction, continuity, and characterization with an undisclosed closed beta preset. The disclosed parameters suggest starting with reasoning=medium, then observing whether high brings a drier style or more overthinking.
These opinions cannot be combined into a general RP score for the model. The blind test did not disclose the four models, the complete prompt, sample size, scoring sheet, or outputs; the positive experience depended on an undisclosed preset; and OpenRouter's free label, throughput, latency, and uptime were from a single page snapshot. "No censorship" was also only one user's description of their experience. The post provides no verifiable long-conversation token counts, context length, retry count, or completion rate. The temperature and top_p shown by the client do not equal the sampling values actually used by the model; this post cannot prove that they changed generation behavior.
Fix the provider and model snapshot in SillyTavern, and record temperature, top_p, the reasoning level, context limit, lorebook settings, character cards, and swipe count. Using the same characters, opening, and clearly defined long-conversation tasks, test at least reasoning=medium and high separately, recording continuity, retention of character goals, proactive plot advancement, clichés, stylistic dryness, overthinking, and failure count. If using OpenRouter, record the endpoint status and actual provider separately; do not treat the free-endpoint page snapshot as permanent availability.
