Everything you need to build with the LLMAI API gateway.
Getting Started with LLMAI
LLMAI is an AI model gateway that gives your application access to 32 models across 9 provider families — including frontier models from OpenAI (GPT-5.4, GPT-5.5, and the GPT-5.6 family), Anthropic (Claude Opus 4.6 / 4.7 / 4.8 and Sonnet 4.6 / Sonnet 5), and Google (Gemini 3.x, Gemma 4, plus image/video models like Veo 3.1 and Nano Banana) — alongside Kimi, MiniMax, DeepSeek, Alibaba Qwen, Z.AI GLM, and Xiaomi MiMo. All available through a single, OpenAI-compatible HTTP endpoint. Register once, load your account balance, and call any supported model using the same request format.
Customers typically save over 65% on AI API costs compared to going direct to providers — one API key, all models, a fraction of the cost.
🎁 Free $2 trial credit available on request. Not ready to deposit? Contact us to request trial credit and test any model before you commit.
