Looking for a single AI API platform that handles everything — video generation, image creation, music production, and LLM chat? Stop juggling multiple API providers. Kie.ai is the answer — a unified AI API marketplace offering 309+ models under one roof.
What Is Kie.ai?
Kie.ai is an AI API marketplace — a middleware platform that gives you access to hundreds of AI models through a single API key. Instead of managing separate accounts for OpenAI, Anthropic, Google, Fal.ai, and others, you just need one Kie.ai account.
Key categories and model counts:
- 🎬 Video Generation (177 models): Google Veo 3.1, Runway Aleph, Seedance 2.0 (ByteDance), Kling 3.0, HappyHorse, Wan2.7 Video
- 🖼️ Image Generation (72 models): GPT-4o Image, Flux.1 Kontext, Nano Banana, Seedream 5.0, Qwen Image 2.0
- 🎵 Music Generation (21 models): Suno API V3.5, V4, V4.5, V4.5 Plus — generate music up to 8 minutes
- 💬 Chat/LLM (39 models): Claude Sonnet 4.5/4.6, Claude Opus 4.6, GPT-5.4, Gemini 3.1 Pro
