What happened?

NVIDIA has open-sourced Flora, a data engine built to label robot videos. The system automatically labels footage of robot movements to speed up the production of training data.

The cost gap

According to NVIDIA's figures, Flora labels one hour of robot video for 72 cents. The same task costs $88 with GPT-6 Astra, a roughly 125x difference. The company says Flora also edges ahead slightly on quality score.

How it works

Flora is built on three fine-tuned Qwen3.5 models. It catches errors in robot actions far more reliably than competitors, though it sometimes falls short on descriptive accuracy.

Why it matters

NVIDIA is positioning Flora as a key piece of its strategy to control the entire robotics value chain. The open-source approach could lower the cost of robotics training data and make it easier for more teams to train their own models.
