GLM-4.7-Flash K-Guard Soft 56E Control

Public research-control checkpoint from the GLM-4.7-Flash K-Guard REAP study.

  • Routed experts: 64 → 56 per MoE layer (12.5% pruning)
  • Active experts per token: top-4 unchanged
  • Base revision: 7dd20894a642a0aa287e9827cb1a1f7f91386b67
  • Role: soft-protection control
  • Fine-tuning: none
  • Precision: BF16
  • Status: experimental; release_eligible=false

This checkpoint is published for reproducibility and controlled comparison. It is not the strict K-Guard 56E release candidate. It was evaluated in B22 and later selected over a new KO85 candidate on the separate B25 development set; because B25 retained the existing model, B26 correctly did not reinterpret its earlier held-out results as a new held-out run.

B22 controlled benchmark

All models below use the same 56E budget. Values are percentages. LiveCodeBench uses v6, greedy n=1, so it is not directly interchangeable with official n=10 leaderboard scores.

Metric Base 64E SameCal REAP 56E Soft K-Guard 56E
Korean MC macro 68.79 66.79 66.79
Academic 10-benchmark macro 65.51 64.51 64.97
Coding 3-benchmark macro 58.28 57.54 58.38

The Korean macro difference between Soft K-Guard and SameCal REAP was approximately 0.00 pp with a paired stratified bootstrap 95% interval of [-1.02, 1.03]. This run therefore does not establish a Korean causal advantage from soft protection. It is a useful control, not evidence of a general improvement.

Use a recent Transformers version that supports Glm4MoeLiteForCausalLM.

Limitations

  • One calibration run and one 56E budget; calibration-seed stability is unknown.
  • The checkpoint is not production-certified and has no fine-tuning recovery.
  • Top-4 routing is unchanged, so checkpoint reduction does not by itself prove higher decode throughput.
  • The public weights support reproducibility; the experiment code and detailed manifests remain in the associated private research repository.
