  "account": "SteerDistill is a novel technique that shrinks 30-billion-parameter language models down to a 3-GB footprint while maintaining accuracy. The method uses a closed-loop teacher-steering pipeline that corrects quantized hidden states in real time. In a debugging case study, the authors demonstrate how SteerDistill can fix a hidden-state drift issue in a webshop agent, improving its accuracy by only 2 percentage points compared to the full-precision teacher. The authors report that SteerDistill cuts inference latency by half, reduces GPU memory use by three-quarters, and mitigates environment-condition failures by 73%. The method is agnostic to the quantization algorithm used and has been tested on multiple popular quantizers. However, the authors do acknowledge certain risks such as a residual performance gap, adapter overfitting, increased teacher query cost, compatibility with non-transformer agents, and security concerns. They propose several mitigations for these risks and suggest further improvements to the technique.",
  "summary": "SteerDistill — How Closed‑Loop Teacher Steering Rescues Quantized LLM Agents Lead “Quantizing a 30‑billion‑parameter agent drops its success rate by 20 %—that’s the headline most engineers see.” Yet the arXiv pre‑print released on 10 Nov 2026 flips that narrative. The authors demonstrate a closed‑loop teacher‑steering pipeline that squeezes a 4‑bit LLM agent down to a 3‑GB footprint while keeping…",
