| Version | Release | Key Changes |
|---|---|---|
| v1.0 | 2024-06 | Initial T2V + I2V |
| v1.5 | 2024-09 | 1080p, motion brush, I2V-only model |
| v1.6 | 2024-11 | Lip sync, camera paths, effects API |
| v2.0 | 2025-03 | Quality leap, kling-v2-master |
| v2.1 | 2025-06 | Optimized I2V, kling-v2-1-master for T2V |
| v2.5 Turbo | 2025-09 | 40% faster, best speed/quality ratio |
| v2.6 | 2025-12 | Native audio, 30-48 FPS, highest quality |
# v1.x request
body = {
"model_name": "kling-v1-6",
"prompt": "A sunset over mountains",
"duration": "5",
"mode": "standard",
}
# v2.x -- only model_name changes
body["model_name"] = "kling-v2-master"
Breaking changes:
kling-v2-1 is I2V-only (no text-to-video support)body["model_name"] = "kling-v2-6"
body["motion_has_audio"] = True # NEW: synchronized audio
# Cost impact: audio multiplies credits 5x
# 5s standard: 10 -> 50 credits

npx claudepluginhub jeremylongshore/claude-code-plugins-plus-skills --plugin klingai-packCatalogs Kling AI models for video (T2V/I2V), image generation, lip sync, and effects with versions, speeds, qualities, resolutions, and costs for selection.
Generates videos from text prompts or images, animates still images, and creates talking avatars from photos with audio using Kling AI models (VIDEO 3.0, Avatar 2.0, etc.). Handles multi-shot storyboards, character consistency, and prompt engineering.
Upgrades ElevenLabs JS/Python SDKs and migrates v1-v2/v3 models, handling package renames, import changes, and API deprecations.
