The Best Free AI Models for Roleplay in 2026 (JanitorAI and SillyTavern)
By Vibhek SoniUpdated 2 min read
Quick answer
For most roleplay, start with fta/zai/glm-5.3: strong writing and a 1M-token context. Use fta/kimi/k3 when you want careful, thought-through replies and can wait, and fta/bbl/gemini-3.5-flash when you want short, quick replies.
Key takeaways
- GLM 5.3 is the best default: good prose, long memory, reasonable speed.
- Kimi K3 thinks before it answers, so it is slower but more deliberate.
- Gemini 3.5 Flash suits short, snappy turns.
- Very long chats slow every model down; trim history for faster replies.
Side-by-side comparison
| Model ID | Context | Speed | Style |
|---|---|---|---|
fta/zai/glm-5.3 | 1M tokens | Medium | Rich, descriptive prose; follows character cards well |
fta/kimi/k3 | 1M tokens | Slow first token | Deliberate and consistent; thinks before writing |
fta/mmx/minimax-m3 | 1M tokens | Medium | Different voice; handy when a chat feels repetitive |
fta/bbl/gemini-3.5-flash | 1M tokens | Fast | Clean, concise replies |
Every model here is free on FreeTheAI. The Models page has the full list with context sizes.
GLM 5.3: the best default
GLM 5.3 writes vivid, detailed replies and keeps track of long stories thanks to its 1M-token context. It is the model we suggest first in every roleplay guide. Some messages can be stopped by the model's own content filter; if a reply is blocked, rephrase slightly or switch models for that scene.
Kimi K3: careful and consistent
Kimi K3 is a thinking model. It reasons before it writes, so the first words can take 10 seconds or more, and on very long chats even longer. In exchange its replies stay consistent with the story. JanitorAI sometimes gives up waiting and shows "No response from bot"; the error guide explains what to do.
Gemini 3.5 Flash: short and quick
When you want quick back-and-forth rather than long paragraphs, Gemini 3.5 Flash keeps replies clean and concise. It is also a good fallback when another model is busy.
Settings that make any model better
- Max tokens 0 uses the model's full output length, so replies do not stop mid-sentence.
- Streaming on shows text as it is written and avoids timeouts.
- In SillyTavern, set Prompt Post-Processing to Semi-strict; some models refuse chats that reach them without a message from you.
- Trim long histories. Huge contexts are supported, but a shorter chat answers faster.
