Model Card
Kling Image 2.1 is a text-to-image generation model from Kuaishou, the company behind the Kling AI video and image models. It is described as a high-fidelity model known for detailed photorealistic output, natural lighting, and strong character consistency.
The model supports eight aspect ratios (16:9, 9:16, 1:1, 4:3, 3:4, 3:2, 2:3, and 21:9), which covers landscape, portrait, square, and ultrawide formats without cropping afterward. Through Puter it costs about $0.014 per 1k image, so it is inexpensive to use for batches and iteration.
It suits developers who need photorealistic images or consistent characters across generations, such as portraits, product and food scenes, interiors, and marketing visuals. No official benchmark scores have been published for this model.

More AI Models From Kling
Kling 3.0 Turbo
Kling 3.0 Turbo is a video generation model from Kuaishou's Kling team, released as a faster, lower-cost variant in the Kling 3.0 family. It generates video with synchronized audio and is tuned for quick turnaround in high-volume workloads. The release notes highlight improved lip-sync, which makes it a fit for talking-head and dialogue clips. Through the API it supports 720p and 1080p output at 24 FPS, with clip lengths from 3 to 15 seconds. Choose it when generation speed and cost per clip matter more than maximum fidelity. Third-party comparisons say the original Kling 3.0 remains the better pick for 4K output and its storyboard tooling. It suits developers building apps that generate many short clips, such as marketing videos, social content, and spoken-word scenes.
ImageKling Image 3.0
Kling Image 3.0 is a text-to-image model from Kuaishou's Kling AI, released as part of the Kling 3.0 series alongside Video 3.0, Video 3.0 Omni, and Image 3.0 Omni. Kuaishou describes the series as having major upgrades in consistency and photorealistic output. It did not publish benchmark numbers for the image model in the sources we found, so we do not cite any here. Through the API it supports eight aspect ratios (16:9, 9:16, 1:1, 4:3, 3:4, 3:2, 2:3, and 21:9), which covers landscape, portrait, square, and ultrawide layouts. It costs $0.028 per 1k image. It suits developers who want photorealistic output from a single model at a low per-image price, and who need flexible output shapes for web, social, or banner use.
VideoKling 3.0
Kling 3.0 is a video generation model from Kuaishou, released in February 2026 as the successor to Kling 2.6. It generates video from text prompts and reference images, and produces synchronized audio together with the video. It supports multi-shot generation, so a single prompt can produce a clip with several cuts, and clips run up to 15 seconds. An Elements feature lets you supply reference images or clips to keep characters consistent across shots. Audio includes dialogue bound to specific characters in English, Chinese, Japanese, Korean and Spanish. On Puter, it accepts durations from 3 to 15 seconds and outputs at 720p, 1080p or 4k. Kling 3.0 suits developers building short narrative clips, character-driven scenes or ads where multiple shots and spoken audio need to come from one API call.
