SpiritBox Ultimate R7.7.1 · Windows Early Access
Use Guides to set reusable conversation instructions and keep saved chats in one interface. Ultimate uses its bundled local engine by default, with LM Studio available as an optional backend. It is for technical Windows users with Docker Desktop and WSL2/Linux containers.
Consider Ultimate if you want to evaluate its Guide-based conversation interface and local setup. LM Studio already supports saved chats and reusable prompt presets, so those features alone are not a reason to buy another app. Review the bounded testing evidence before spending $199 USD.
One-time purchase. Models are separate. Existing checkout terms and purchase rights remain unchanged.
The download
The application, Windows setup scripts, bundled-engine quick start, optional LM Studio instructions and third-party notices. Models are separate downloads.
Extract into a new empty folder and follow QUICK_START.md. For the optional LM Studio route, use LMSTUDIO_FIRST.md. Preserve your existing configuration and data backups. Do not overwrite an existing installation's data or delete its volumes.
Optional services require separate setup and qualification. ComfyUI models, nodes and workflows and n8n are not supplied as a configured, tested workflow bundle. Full retrieval/graph, VoiceLab training and live Telegram/n8n workflows require separate configuration and validation. n8n is user-managed.
Testing evidence
The bundled Qwen3-14B route completed a checklist on R7.6 and preserved it through restart. Optional LM Studio GPT-OSS20B completed a factual summary on R7.7, then preserved the identical answer through reload, reopening and app restart.
A captured empty model response was replayed offline on R7.7. The explicit incomplete-response notice persisted after reload and reopening. R7.7.1 fixes Windows launcher path quoting with six small edits across three batch files. All 56 lightweight launcher and preflight tests passed against the extracted hotfix. Prior R7.6/R7.7 runtime evidence is unchanged; a fresh installation with real Docker and a model was not rerun for this hotfix. No new voice generation was performed. Read the full evidence boundary.
Before checkout
Hardware needs depend on your model and configuration. This release does not establish a general minimum RAM or VRAM requirement.
Full-workstation features, other hardware, other models and long conversations remain unqualified.
