Nvidia open-sources Flora to make robot video labeling 125x cheaper than GPT-6 Astra

AI summary Nvidia has released Flora, an open data engine that annotates robot training videos using three fine-tuned Qwen3.5 models, now published on Hugging Face. The company estimates that labeling an hour of footage costs about 72 cents, compared with roughly $88.50 for GPT-6 Astra, though these are projections based on an assumed $10 per GPU-hour. Nvidia says Flora already processes as many as 200,000 video hours per day using 512 GB300 GPUs for GR00T training. In tests, Flora-Rewarder detected 53.3% of unsuccessful steps inside episodes while Astra caught none, but Astra still did better on some description benchmarks.
