办公Agent大战正酣，真正的胜负手却藏在看不见的地方

TL;DR — A 机器之心 profile of Pyromind（火思动力）, an Oct-2025 startup positioning itself as an "RLaaS" / AutoRL platform that productizes post-training so deployed office and robotics Agents keep improving from real task feedback. It matters because it frames continual learning — not demo-stage task completion — as the real competitive axis for enterprise Agents.

• Reliability gap motivates the pitch: cited Fiddler AI data says enterprise Agents at ~60% single-run success drop to ~25% over 8 consecutive production runs; a Princeton evaluation of 14 Agents reportedly found reliability lagging accuracy gains over 18 months.
• Why existing methods fall short (per the article): pretraining sets the ceiling but is costly and generic; context/memory retrieves rather than internalizes; SFT needs expensive static expert trajectories and lacks self-correction for multi-step, delayed-feedback tasks — hence RL-based post-training as the closed loop (collect → analyze → reward → train → validate → update).
• AutoRL product stack, three layers: drag-and-drop training-pipeline infra (SFT/GRPO/DPO plus robot simulation sandbox), generative reward construction (accuracy- and preference-oriented), and "invisible" post-training that auto-collects sessions, retrains in background, and canary-rolls new endpoints under a user-set budget cap.
• Claimed results and traction: PyroDash small+large model collaborative inference (open-sourced model/data/code, arXiv report) beats a pure large-model baseline average accuracy on five math-reasoning benchmarks with >90% cost reduction in cost-leaning configs; R2VLA turns existing rule-based factory systems into a 24/7 auto-labeling data factory cutting robot data collection time >50%; team reports 7th at ICRA 2026 embodied challenge, ~$10M-level funding (Hillhouse, Baidu Ventures, BlueRun, etc.), and customers including UBTECH.
