ANTHROPIC_BEDROCK_REGION_PREFIX
What
A new environment variable lets Bedrock users choose which regional inference-profile prefix models resolve to. Accepted values are us, eu, apac, jp, au and global. It is added to the environment passthrough sets used for sandboxed and spawned processes, so child processes inherit it.
Details
- An older seven-entry region list including
us-govis kept separately, used for parsing Bedrock hostnames rather than for this variable. - Setting a prefix that cannot be confirmed, or models that resolve to a different prefix, produce warnings (see below).
Usage
export ANTHROPIC_BEDROCK_REGION_PREFIX=euEvidence
