Kling 2.5 I2V (Pro)

Released in Sept 2025, this Kling model from the "2.5 Turbo" family uses a first-frame image and a text prompt as input. It is engineered to prioritize generation speed, delivering 1080p output up to 2x faster than the 2.1 series and at a ~30% lower cost. This model supports only first-frame conditioning for controlled starts and lacks the last-frame control found in models like O1 I2V. It represents a trade-off, prioritizing faster and more affordable image-to-video animation over the more advanced control or audio features of other Kling families.
