Nvidia open-sources Flora, a video annotation engine for robotics
What happened
On 25 October 2026, Nvidia open-sourced Flora, a data engine that generates three kinds of annotation for robotics video: motion segments, step-by-step scores and task success or failure. The models are available on Hugging Face. Flora consists of three fine-tuned Qwen3.5 models. Nvidia says it is already running in GR00T model training, annotating up to 200,000 hours of video a day on 512 GB300 GPUs, and claims the cost is 125 times lower than GPT-6 Astra.

- The DecoderNvidia open-sources Flora to make robot video labeling 125x cheaper than GPT-6 Astra
Nvidia's new data engine Flora labels one hour of robot video for 72 cents instead of $88 with GPT-6 Astra, while scoring slightly higher on quality. The open system, built on three fine-tuned Qwen3.5 models, catches errors in robot actions far more reliably than any competitor but sometimes falls short on descriptive accuracy.
