OpenAI API Compatible

Run 10× more AI models on the same GPUs without cold starts

GreenThread is a high-density inference engine that keeps execution resident and swaps model state on demand. OpenAI-compatible, enterprise-ready, and built for operators who care about utilisation, latency, and control.

Built for high-density inference

Serve many models concurrently without dedicating hardware

50+ models per GPU node

Run an order of magnitude more models on the same hardware — without cold starts.

Sub-2s deterministic model wake

Predictable model activation in seconds, not tens of seconds. No engine restarts required.

Zero engine restart overhead

No Python, CUDA, or runtime reinitialisation on model switch. The inference engine stays resident.

Designed for GPU operators

Most inference platforms restart the engine when switching models. GreenThread keeps the engine alive and swaps model state instead — so GPUs stay busy and models stay responsive.

  • Host large model catalogs without one-model-per-GPU economics
  • Handle bursty demand without cold starts
  • Maintain data sovereignty and infrastructure control
