Community evidence corroborates that the headless flow makes local inference usable from real tools rather than just as a demo, though one comment notes wishing for a 'pure daemon mode' without the full Electron UI for the main app (addressed by llmster). missing for 10: independent hands-on validation of llmster specifically in a CI pipeline, and more detailed docs on scripting/automation patterns beyond CLI reference.

   Jan~partialclaimed4/10

   Jan supports downloading/running local models and custom assistants, implying some per-model management, but there's no concrete evidence of a unified UI for managing saved prompts or per-model configuration settings in one place. Missing for 10: dedicated prompt-library management, explicit per-model config UI, and independent hands-on confirmation of a unified management view.
