  "title": "ComputerSD: Online Self-Distillation from Real-Time Feedback for Computer-Use Agents",
  "summary": "ComputerSD replaces outcome-only GRPO training of computer-use agents with joint token-level self-distillation (using real-time GUI feedback from a fine-tuned analyzer) plus trajectory-level GRPO. It costs an additional fine-tuned GUI analyzer model, privileged rescoring per step, and a fully asynchronous online training framework that requires an executable GUI environment — infrastructure beyond a single 24 GB GPU for the 8B backbones used. Failure modes include misalignment between the analyzer's guidance and the student's evolving state, analyzer errors propagating as flawed supervision, and modest absolute gains (1.9–4.1 points) that may not generalize beyond the evaluated backbones.",
  "rationale": "The method requires online RL infrastructure, an executable GUI environment, and training capacity for 8B vision-language models, none of which fit the reader's single 24 GB GPU and limited budget, though the results are worth tracking for future capability.",
