Nvidia open-sources Flora to make robot video labelling 125x cheaper than GPT-6 Astra
Nvidia's open data engine Flora labels an hour of robot video for 72 cents, against $88 with GPT-6 Astra, with slightly higher quality scores. Built on three fine-tuned Qwen3.5 models, it is far better at spotting errors in robot actions but sometimes less accurate in its descriptions, and Nvidia sees it as part of a push to cover the whole robotics value chain.
