ChatGPT kompakt

Vendor: gpt-6-luna, as of 29 September 2026

The smallest size class of OpenAI's GPT line, not meant for assessment and drafting but for the mechanical intermediate steps in a file: pulling fields from receipts, classifying documents, normalising lists. Where the result is checked anyway, it is the most economical tier of the family. The load-bearing route is Azure: there the model is sold and operated by the platform itself, processing stays inside the EU, and the confidentiality undertaking under section 203 of the German Criminal Code is signed in text form - the chain is closed on this route. The abuse monitoring active by default has to be settled separately.

Through us once the provider clears it

The confidentiality agreement under section 203 of the German Criminal Code is signed. We set the route up without storage at the provider (zero retention) once the provider has committed to it - at Microsoft through the exception from abuse monitoring, which usually takes months. Until then, storage and review by the provider are not ruled out.

What it is good for

Lowest cost and latency tier of the family - suitable for bulk steps in a processing chain
EU processing in seven EU regions; same contractual line as the large classes
Sufficient for structured extraction where the result is checked anyway

Where it stops

Not suitable for substantive assessment, subsumption and drafting - the large or the reasoning class is intended for that
Abuse monitoring is active by default; switching it off depends on a vendor approval that cannot be booked directly
On the retention period in the abuse data store we found no publicly available product document with a stated term (as of 2026-08-17)

Status through us

The same model, procured differently, is a different legal position. The status above refers to procurement through us; processing takes place in a third country.

Which route carries it, with which instrument and under which condition, we set out in full to the firm before it commissions us - section 203(4) requires that the chain can be checked, not that it is published. The full matrix, with the sources behind every route, can be requested in the German catalogue after confirming your e-mail address, and we go through it in the conversation.

Is ChatGPT kompakt the right fit?

We go through your tasks and the route that carries them - and say plainly where it does not.
