What we do
We don't train our own language models — we run the sharpest open-weight models on Swedish hardware. Today we serve GLM 5.1 — the open-weight flagship from Z.ai (754B MoE, 40B active parameters, 200K context, MIT license) with strong benchmark performance per the provider's published measurements. One model, one OpenAI-compatible API. All inference runs on our own NVIDIA H200 hardware on Swedish soil — no external model providers.
Two products on the same cluster: Grunden API for developers and companies (token-based, three priority tiers — Priority, Normal, Async) and Grunden Chat for consumers and teams (subscription — Free, Plus, Pro, Team).
Hardware
Our own NVIDIA hardware on Swedish soil — not rented capacity at a hyperscaler. One cluster in production, one on its way:
- HGX-H200 (8× NVIDIA H200 SXM) — 1,128 GB VRAM, 8× 400 GbE NDR Infiniband. Delivered by 6G AI Sweden AB in Kista, Stockholm. In production since May 2026 — runs GLM 5.1 via SGLang.
- Supermicro AS-8126GS-NB3RT (8× NVIDIA B300 Blackwell Ultra) — 2× AMD EPYC 9575F, 3 TB DDR5, 60.8 TB NVMe. Delivered by Glesys AB. Scheduled for production summer 2026.
Team
We're a small team investing in our own GPU hardware on Swedish soil — and demonstrating that route is achievable.
