Nvidia open-sources Flora with projected robot video labeling costs up to 125x lower than GPT-6 Astra
Nvidia released Flora, an open robotics video annotation engine comprising three fine-tuned Qwen3.5 models that segment actions, describe them, and generate reward signals. Nvidia estimates labeling costs of $0.72 per video hour versus $88.49 for GPT-6 Astra, based on assumed GPU rental prices rather than production measurements. Benchmark results vary, with Flora stronger at action boundary detection and failed-step identification, while Astra leads on some description and rubric-based scoring tasks.
