## Summary
The LocalAI 4.12.0 release brings significant updates to the self-hosted AI platform, including a complete web UI redesign with light and dark themes. New features include streaming voice responses via Qwen TTS, native decision routing for request classification, and image upscaling within the Studio workflow. The update also introduces persistent Qdrant stores and enhanced privacy controls like PII filtering.

## Technical improvements in LocalAI 4.12.0
- **Audio & Voice**: Supports incremental Qwen TTS, Parakeet bundles, and configurable Voice Activity Detection (VAD).
- **Decision Routing**: Implements a `/v1/decisions` adapter to handle predicates, choices, and scores via decision models.
- **Inference Controls**: Adds `moe_cache_mib`, `lazy_mode`, and explicit slot prompt-cache save/restore capabilities.
- **Storage & Vector DB**: Integrates persistent Qdrant stores with TLS and environment-backed credentials via the `/stores/*` API.
- **Motion Capture**: Includes a GEM-X API to convert RGB frames into SOMA-77 or SMPL-24 poses using CPU or Vulkan.

## Why it matters
This release prepares LocalAI for a modular future by introducing addon support architecture, allowing components like Studio and Talk to be installed on-demand.
