英伟达开源机器人视频标注引擎 Flora，成本比 GPT-6 Astra 低 125 倍
原标题：Nvidia open-sources Flora to make robot video labeling 125x cheaper than GPT-6 Astra
AI 摘要
英伟达开源了数据引擎 Flora，用于机器人视频标注。Flora 由三个微调的 Qwen3.5 模型组成，可同时生成动作分段、描述和奖励信号三类标注，据英伟达估算，标注一小时视频成本约 72 美分，而使用 GPT-6 Astra 约需 88.5 美元，最高便宜 125 倍。该系统已用于 GR00T 模型训练，每天可标注多达 20 万小时视频，模型已在 Hugging Face 发布。不过成本数字为基于 GPU 租价的推算，且在部分基准上 Flora 的描述精度仍落后于 Astra 和 Gemini 3.8 Flash。

Nvidia open-sources Flora to make robot video labeling 125x cheaper than GPT-6 Astra Labeling one hour of robot video for 72 cents instead of $88 is what Nvidia promises with Flora, its open data engine. But the comparison with GPT-6 Astra isn't quite as lopsided as the price tag suggests. Large AI models for robots learn from videos that need text annotations, and according to Nvidia's GEAR research lab, this requires three types of labels. First, descriptions of what action happens when in the
