Yes, Claude Opus 4.6 can be used commercially under Anthropic’s terms, but the exact permissions and constraints depend on the agreement and policy that applies to your account (developer platform terms, enterprise agreements, and usage policies). As a developer, the practical thing is not the “yes/no,” but the operational implications: data handling, prohibited use cases, and how you must present or restrict certain behaviors in your product.
A responsible commercial rollout should include a compliance checklist: where prompts and outputs are stored, how you handle personal data, how you deal with user-generated content, and how you prevent disallowed use. You should also implement a clear audit trail: store request metadata (not necessarily the full text), tool-call logs if you use tools, and a mechanism to respond to abuse reports. Make sure your product UI and documentation reflect what users can and cannot do.
If your commercial use case involves answering from proprietary documentation, retrieval helps keep you aligned with your own content and reduces leakage risk. Store only the embeddings and metadata you need in Milvus or managed Zilliz Cloud, apply access controls at retrieval time, and pass only authorized chunks into the model prompt. This makes it easier to enforce “tenant isolation” and to comply with internal security policies.
