Nvidia open-sources Flora for cheaper robot video labeling
Nvidia has open-sourced Flora, a data engine that labels robot video using three fine-tuned Qwen3.5 models. Nvidia reports it labels an hour of robot video for 72 cents versus $88 with GPT-6 Astra, while scoring slightly higher on quality and catching robot action errors more reliably, though it sometimes lags on descriptive accuracy. Nvidia frames Flora as part of its push to control the robotics value chain.
