A household of AI companions you actually own. Wyrdsekai is a self-hosted, open-source companion world: persistent characters with their own drives, rooms, memory, and voice, running on your hardware — a Linux box, a Mac, a Windows machine, or a phone. Households federate with each other; nothing routes through us.
Two fine-tuned tiers run every household, in two formats each:
| llama.cpp (GGUF) | Apple Silicon (MLX 4-bit) | |
|---|---|---|
| Drive 9B — decides & acts (planning, tools, own-time initiative) | drive-3.5-9b-gguf | drive-3.5-9b-mlx |
| Companion 4B — speaks (voice, register, per-companion individuation) | companion-3.5-4b-gguf | companion-3.5-4b-mlx |
Both are fine-tunes of Qwen3.5 (Apache 2.0), trained on synthetic corpora only — no end-user or household conversation data is in these weights. In a running household, companions keep learning; that growth stays on your node. The released weights are the seed. Your companion's becoming is yours.
