Veo 3.1 Lite
Model Card
Model Cards are intended to provide developers with essential, summarized information on
models, including overviews of known limitations and mitigation approaches. Model cards may be
updated from time to time; for example, to include updated evaluations as the model is improved
or revised.

                                             Evaluation

Evaluation Approach: We evaluated Veo 3.1 Lite vs Veo 3.1 Fast across both T2V (prompt-to-video
generation) and I2V (image-to-video generation).

Results: Veo 3.1 Lite T2V achieved 54.6% overall win-rate across 1000 prompts and I2V achieved
47.2% overall win-rate across 646 prompts.

Veo 3.1 Lite is based on Veo 3. For more information about the evaluation approach for Veo 3.1 Lite,
see the Veo 3 model card.
