 "title": "Cap memory and keep the GPU off on a shared machine",
 "page_title": "How to cap memory and keep the GPU off on a shared machine with Janas",
 "summary": "Start Janas-LLM with a memory limit or without the GPU so it does not take over a shared computer.",
 "who": "A user on a shared or work machine who wants a local model without it filling the memory or touching the GPU.",
 "problem": "The engine fills free memory with its expert cache and can use the GPU, which may disturb other work on the same machine.",
 "outcome": "A chat session that keeps to a set memory limit and runs on the CPU only.",
 "steps": [
  "Run the chat with the GPU off (inferred): `JANAS_GPU=0 ./janas-chat` (inferred, check the README)",
  "To cap memory, start the chat with the `--cache` option set to a limit of your choice (inferred flag form, check the value the README gives in docs/chat.md)",
  "Watch the desktop responsiveness during the first replies",
  "Stop a reply with Ctrl-C if the machine slows down"
 ],
 "agent_prompt": "In the janas repo, run JANAS_GPU=0 ./janas-chat and ask one short question. Report the reply and confirm from the output that no GPU was used. Verify that the process ended cleanly after Ctrl-D.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "30 minutes",
 "basis": "readme",
 "caveat": "The README warns that using a GPU has once caused a driver reset that took the desktop with it, so keeping the GPU off is the safer choice on a machine you cannot afford to lose.",

  "A terminal on the machine",
  "Enough free disk space for the model you pick; the README lists Qwen3-Next-80B at 48.4 GB",
  "A machine with 32 GB of RAM is the one the README measured on; other machines are untested"
