 "title": "Export routed-expert cache traces for analysis",
 "page_title": "How to export routed-expert cache traces for analysis with Kimi K3 in C",
 "summary": "Dump expert usage traces from a run so the included cache simulator can replay them.",
 "who": "A systems researcher who wants to study how the routed-expert cache behaves under real Kimi K3 routing.",
 "problem": "Tuning a cache for a 2.78T mixture model needs real routing data, and guessing from theory is unreliable.",
 "outcome": "A directory containing expert_hist.json and expert_trace.bin, ready to replay with tools/sim_cache.py.",
 "steps": [
  "Build the engine and download the checkpoint and trunk as in the batch use case. (inferred, check the README)",
  "Run a generation with --dump-cache-trace <trace_dir> added to the laptop preset command. (inferred, check the README)",
  "python tools/sim_cache.py <trace_dir> (inferred, check the README)"
 ],
 "agent_prompt": "In the repo FareedKhan-dev/kimi-k3-in-c, run a short generation with --dump-cache-trace <trace_dir> and --incremental. Expect expert_hist.json and expert_trace.bin in that directory. Verify both files exist and are non-empty before replaying them with tools/sim_cache.py.",
 "agents": [
  "any"
 ],
 "difficulty": "Advanced",
 "time": "1 h 30 min (excludes the checkpoint download)",
 "basis": "readme",
 "caveat": "The README does not show the exact arguments for sim_cache.py, so check its usage in the tools folder before running it.",
 "category": "Research",
 "tags": [
  "Research"
 ],
 "lang": "c",
 "requirements": [
  "A checkpoint directory of .safetensors shards (1.56 TB on disk for the released checkpoint)",
  "A packed trunk directory, created in a step the README excerpt does not show",
  "tiktoken.model and tokenizer_config.json in a directory, for text input",
  "A machine with a C toolchain for the portable C99 build (build steps are not in the excerpt)",
  "An HF_TOKEN environment variable if you use download-model.sh"
