grunden.ai is a Swedish AI service for developers, public agencies and ordinary people. GLM 5.1 (open-weight) with EU jurisdiction, an OpenAI-compatible API and pricing in Swedish kronor.
Is your AI running in Texas? We think it should run in Stockholm. grunden.ai provides GLM 5.1 from Stockholm — GLM 5.1 matches the capabilities of ChatGPT and Claude.
Swedish law. Swedish invoicing. Swedish support. No third party in the data path. No legal deep-dive needed to track where your prompts went. No grey zones under GDPR or the AI Act.
A foundation to build on.
A chat that's as comfortable as the ones you already use. Upload PDFs, share a thread with a colleague, gather projects in folders. Native-level Swedish output.
Swap base_url and keep going. Same SDK, same chat completions, same streaming. No proprietary client libraries to learn.
Prompts are not used for model training. Data processing agreement (DPA) in Swedish. External certifications (ISO 27001, BSI C5, EUCS) are seed-round goals and are not yet achieved.
Pricing per million tokens in SEK, not exposed to USD exchange-rate swings. Invoice with F-skatt and a Swedish bank account. Annual plans on chat give a 17% discount.
