Andrew Ho Leaves OpenAI to Launch Startup Producing High-Quality RL Datasets for Scientific Reasoning
English summary
Andrew Ho announced his last day at OpenAI after eight months, revealing he is starting a new company focused on producing high-quality reinforcement learning datasets. He argues that LLMs have poor generalization and that economically productive capabilities are underrepresented in existing data, predicting that frontier labs will need to spend over $100B on targeted data acquisition. The company's first products will target biology and statistical reasoning: long-horizon scientific reasoning datasets based on GeneBench-Pro, where GPT-5.6 Sol's pass rate is barely above 30%, aiming to push reliability to over 90%; and multimodal datasets covering day-to-day scientific tasks such as analyzing cell culture plates or Western blots. Beyond biology, expansion is planned into chemistry, materials science, healthcare, and white-collar office work.
Chinese summary
Andrew Ho宣布在OpenAI任职八个月后离职，并创办一家新公司，专注于生产高质量的强化学习数据集。他指出大型语言模型泛化能力差，现有数据未能很好地呈现经济生产力相关的任务，并预测前沿实验室将需要投入超过1000亿美元进行精准数据采集。公司首批产品聚焦生物学和统计推理：基于GeneBench-Pro的长周期科学推理数据集（GPT-5.6 Sol通过率仅略高于30%），目标将可靠性提升至90%以上；以及覆盖日常科学任务的多模态数据集，如分析细胞培养皿或Western blot图像。后续计划拓展至化学、材料科学、医疗和白领办公领域。
