 "title": "Speed up chat replies with draft tokens",
 "page_title": "How to speed up chat replies with draft tokens with Janas",
 "summary": "Enable draft decoding for supported Qwen and Gemma models to get faster chat replies.",
 "who": "A user chatting with a Qwen3.5, Qwen3.6, Qwen3-Next, or Gemma 4 model who wants faster answers to ordinary questions.",
 "problem": "Writing a reply one token at a time is slow on a model this large, even when the machine can run it.",
 "outcome": "Chat replies at a higher rate, with the same text, when the model supports drafts.",
 "steps": [
  "Install and start the chat as in the Try it section",
  "Choose a supported model such as Qwen3-Next-80B-A3B or Gemma-4-26B-A4B-it",
  "Turn drafts on for the chat (inferred flag form): `./janas-chat --mtp` (inferred, check the README)",
  "Ask an ordinary English question and time the reply",
  "Compare the tokens-per-second with and without drafts"
 ],
 "agent_prompt": "In the janas repo, start ./janas-chat --mtp with Qwen3.6-35B-A3B selected and ask it to explain how bread is made at home. Report the tokens-per-second shown and confirm the reply is complete.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "1 hour",
 "basis": "readme",
 "caveat": "The README says the draft gain depends on the text, and on Italian prose one model kept only about a third of its drafts and gained little.",
 "category": "Software and DevOps",
 "tags": [

 "lang": "c",
 "requirements": [
  "Linux x86-64 (Ubuntu 22.04, Debian 12 and later) or Windows 10 (1903 or later) or 11, x86-64",
  "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"
