Jim Fan 宣布开源 Flora，一组用于解析物理世界、把原始视频转成训练信号的开放模型，称其以 125 倍更低的成本达到 Astra 级性能。Flora 已用于其内部数据引擎，在 500 块 GPU 上每天标注 20 万小时视频，提供带时间戳的高质量字幕、用于质量控制和 RL 后训练的密集进度奖励，以及用于现实基准测试的 rubrics 评分。

We built a robotics data engine with Astra-level performance at 125x lower cost. And we are open-sourcing the weights today! Introducing Flora, a suite of open models to parse the physical world and turn raw footage into rich training signals.

Flora already powers our in-house data engine, labeling 200K hours of videos a day on 500 GPUs. We created it to scale the frontier for robot learning. Now you own the weights too.

Flora gives you:

• High-quality, timestamped captions to curate and filter human egocentric and robot data;
• Dense progress rewards for quality control and RL post-training;
• Rubrics scoring for real-world benchmarking
