EX-1 27B: our security-tuned model is on the API

Task-tuned in-house, smaller and cheaper than a frontier model on its own turf — with a playground on chat.ex5.ai and a stable API id.

NVIDIA H200 (141GB) cards are now available on the ex5.ai GPU market in us-ashburn and eu-frankfurt, with per-second billing and the same OpenAI-compatible endpoint for inference jobs.

Capacity comes from the EX5-owned fleet first, with marketplace partners extending it at peak. Pay in USDC or $EX5 — the token route carries the platform discount.
