§ 01 — Manifesto

We build for
Sweden first,
Europe next.

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.

For everyday work

Write, summarise, translate.

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.

For developers

OpenAI-compatible API.

Swap base_url and keep going. Same SDK, same chat completions, same streaming. No proprietary client libraries to learn.

For legal

Data that stays in the country.

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.

For the CFO

Billed in kronor.

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.

§ 02 — Two lines of code

Everything you've already written keeps working.

# pip install openai · change two lines
from openai import OpenAI

client = OpenAI(
  base_url="https://api.grunden.ai/v1",
  api_key="sk-grunden-...",
)

# the rest of your code works unchanged
