The thread organizer says the aggregated picks will be parsed into Post #1 as a living guide, and is soliciting feedback on which metrics to track, whether the VRAM brackets should be restructured, and whether to add Docker Compose and systemd deployment recipes.", "body_md": "# \n\nRather than running rigid polls right out of the gate, this thread is designed to gather real-world, operational data from the community.
