TUEN — Ultra

TUEN — Ultra is an AI model hosting and inference platform that lets developers run and integrate generative models through a single API without managing GPU infrastructure. It serves image generation, LLMs, text-to-speech, transcription, and video generation from production-grade endpoints. TUEN runs on bare-metal GPU clusters with custom inference kernels across 5 active regions and 2,048 H100/A100 GPUs, keeping infrastructure "always warm" to eliminate cold-boot latency and request queueing. The platform reports a 2.3ms p50 global average latency and a 99.997% 30-day uptime SLA, with capacity for 12.4M requests per day. Example models and their reported latencies include Flux Schnell for images (340ms), Llama 3.1 70B for LLM inference (12ms/token), VibeVoice TTS (89ms), Cohere Transcribe (120ms), and Nucleus Video (2.4s). Developers access models via REST endpoints with Bearer-token authentication, a TypeScript/Node.js SDK, a real-time code playground, and a CLI (tuen-cli register) for deployment. No credit card is required to start. It targets creators, developers, startups, and AI teams shipping inference at scale who want state-of-the-art generative models without provisioning and warming GPUs themselves.

Developers, startups, and AI teams use it to run image, LLM, TTS, transcription, and video models through one low-latency API without managing GPUs.
