What's actually true about Claude on Vertex AI, cited, not recalled.
Google Cloud's Vertex AI Model Garden offers Claude as a first-party, fully-managed model -- the same underlying Claude models Anthropic serves directly and the same models AWS Bedrock offers, just a third cloud-native hosting surface. Vertex addresses models via publishers/anthropic/models/<model-id> resource names, authenticates through standard Google Cloud IAM rather than a portable ANTHROPIC_API_KEY, and bills through the customer's GCP billing account. This site records every fact as a durable row citing a real source, and follows the exact same structure/shape as subagentbedrock.com -- Bedrock's direct sibling site for AWS instead of GCP -- rather than duplicating its content.
Every row carries a real source_url. No unverified precise model-ID string is claimed -- rows are kept general where a live re-check wasn't performed this session.
Vertex AI, AWS Bedrock, and the direct Anthropic API all serve the identical underlying Claude models -- three hosting surfaces, not three different models.
Google Cloud IAM (service accounts, ADC, OAuth2), not a portable ANTHROPIC_API_KEY -- see Vertex vs. direct API.
