Claude Opus
Vendor version: claude-opus-5 (as of 29 August 2026)
The most capable tier of Anthropic's standard Claude family, built for text work where precision matters: it keeps long chains of argument clean, brings out contradictions between several documents, and hits a register in German that works for pleadings and client correspondence. Under professional-secrecy law the route decides. Via Google Vertex AI the contractual chain is closed: the platform operator has signed the confidentiality agreement under section 203 of the German Criminal Code, and ahead of it the chain obligation under section 203(4) applies. Via Amazon Bedrock, despite far-reaching technical commitments, there is no signable document for that undertaking; buying directly from the vendor and the free consumer access do not carry professional secrets.
Everything section 203 requires is settled, including the provider's confidentiality undertaking. You do not have to clarify anything further.
What it is good for
- Most capable tier of the standard Claude family for complex analysis and drafting
- No content access by Google or Anthropic on the Google platform (Anthropic documentation), zero data retention selectable
- Processing inside the EU
Where it stops
- Highest price and latency tier of the family - for high-volume tasks a more compact tier is the better choice
- EU endpoints carry a 10 percent surcharge
- CLOUD Act exposure remains as long as a US provider sits in the chain
- On the AWS route, binding to the EU is a per-call decision: the European inference profile routes within Europe and, depending on the profile, includes regions outside the EU member states (London, Zurich); a worldwide profile exists for the same model. Without enforcement through an organisational policy the EU location is available but not enforced (research date 2026-08-17)
Routes examined
The same model, procured differently, is a different legal position. What is examined per route is the contract chain, not the model.
| Route | Section 203 status | Version on this route |
|---|---|---|
| Microsoft Azure | not covered | - |
| Google EU platform (Gemini Enterprise, formerly Vertex AI) | covered | - |
| AWS Bedrock (EU region Frankfurt) | conditional | - |
| Direct purchase from the vendor (business customers) | not covered | - |
| Consumer access (free or private subscription) | not covered | - |
The conditions behind a conditional status - which piece is open on which route and who closes it - are set out in the full matrix in the German catalogue, and we go through them in the conversation. The German page for Claude Opus carries the sources with their retrieval dates.
