Customizable AI character roleplay platform featuring free JanitorLLM chats, logic scripts, and multi-model API routing.
Provides unlimited free character chats powered by JanitorAI's in-house LLM (~9K context window on free accounts), with a toggleable JLLM-short mode for snappy, dialogue-focused replies that are 70% shorter.
Lets Janitor+ subscribers tap directly into third-party frontier models via a built-in per-token wallet at a 10% discount, while keeping full BYOK reverse-proxy support with config duplication and reasoning tag display.
Allows creators to build complex characters up to 1 MB in size with multiple intro scenarios and programmable Scripts that trigger dynamic lore or behavioral rules using whole-word matching and built-in debugging tools.
Exposes low-level sampling parameters in the chat menu, including custom Top-K, Top-P, frequency and repetition penalties, forbidden vocabulary lists, and response prefill instructions.
Your own dedicated GPU workspace for open-source AI art and video
Launch a private, dedicated GPU machine in roughly 90 seconds with no installs, drivers or local hardware required, and drive it from any device including a phone.
Run industry-standard open-source interfaces side by side — Automatic1111, ComfyUI, Fooocus, Forge and Kohya — and launch multiple machines at once for parallel work.
Pull models, checkpoints, LoRAs, embeddings and textual inversions from Civitai, Hugging Face or your own drive in one click, and add any extensions or custom nodes.
Each machine is yours alone, with up to 200 GB of persistent private storage, an auto-stop timer, and file access without launching a machine.
