Claude Sonnet 5 is now the default Anthropic model

The newest frontier models are now available and routed by default. Claude Sonnet 5 replaces Claude Sonnet 4.6 as the Anthropic model auto-enabled for new accounts, so fresh workspaces start on the current generation with platform keys and no setup.

• Claude Sonnet 5 by default. New accounts get the routed claude-sonnet-5 model out of the box, and the dashboard assistant now runs on it too.
• Claude 5 family in the catalog. The model catalog picks up Claude 5 models as routed IDs, so flows and agents stay current as versions update.
• Safe migration for existing accounts. A hardened migration tool maps every pre-5 Sonnet variant (dotted, dated, or prefixed) to claude-sonnet-5 across flows, agents, and model configs, with dry runs, backups, and rollback built in.
• Generators upgraded. The flow and product generators now default to GLM 5.2 for faster, higher-quality generation.

Existing model selections keep working; nothing changes until you upgrade.
