02 Why Kosmik

European AI teams can scale without sending data abroad

Kosmik runs models on infrastructure we own.

  • Prompts and outputs are not kept

    We process your request to deliver a result – not to build a lasting record of your work.

  • Never used to train models

    No advertising, profiling, fine-tuning, or dataset building from your content.

  • Kosmik-operated hardware in the EU

    Certified European housing in the Czech Republic, run by our team end to end.

  • GDPR-aligned operations

0.70s

Optimized for fast interactive conversations and low-latency routing.

Longer work

Qwen 3.6 27B

Output throughput
1,467 tok/s
First token (p90)
1.58s
First token (p99)
1.72s

Sustained throughput for bigger responses and heavier sessions.

Time to first token is how long you wait before the answer starts appearing. Output throughput is how fast the model streams tokens once it begins.

05 Our process

From free API key to production

Three steps to evaluate Kosmik in your existing AI workflows.

Contact us

Email us for a free API key and test our models in your own tools and environment.

Try your workflow

Point Cursor, Claude Code, OpenRouter, or your app at our OpenAI-compatible endpoint.

Sign to continue

When you are ready for production, sign a usage contract and receive a production API key.

Same request format as OpenAI's chat API – replace YOUR_API_KEY with yours:

curl https://api.koscompute.com/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"qwen/qwen3.6-27b","messages":[{"role":"user","content":"Hello!"}]}'
