## Staged multi-model loading
|
||||
## CPU and GPU telemetry
|
||||
|
||||
The Live runtime panel now shows overall CPU usage, logical CPU count, load averages, overall GPU utilization, and per-GPU VRAM usage. When multiple logical CPUs are detected, it expands into a scrollable responsive per-core grid. When multiple GPUs are detected, it expands into a responsive per-GPU grid showing utilization, VRAM used/free, temperature, and power when the driver reports them. The grids use auto-fit sizing and bounded scrolling so the panel scales to larger CPU and GPU counts without overflowing the dashboard.
|
||||
|
||||
|
||||
A single **Load selected permanently** action now loads models in verified stages. RAM-only models are attempted first, followed by GPU + RAM models. The backend checks Ollama `/api/ps` after each runner starts and automatically performs one recovery pass for any selected model Ollama evicted. Already resident models are not reloaded. The result includes a retry count and reports when automatic eviction recovery completed, so users do not need to click the load action again manually.
