Anthropic added a 'line' field to their Models API, allowing users to group models without parsing IDs.
READY TO POST:
anthropic's models api now includes a 'line' field. sounds like an easier way to group claude versions like opus 4.5 and 4.6.
noticed a docs change: anthropic added a 'line' field to their models api. could simplify how devs manage different model families.
