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.

Why it matters
The benchmark breakdown puts Nvidia’s projected cost advantage in context, showing how action boundary detection, description accuracy, and reward scoring favor different models across the reported tests.
