…to versioned ones When using google-vertex-anthropic, model IDs like 'claude-sonnet-4-5' were failing to match pricing data because models.dev stores them with date suffixes like 'claude-sonnet-4-5@20250929'. This caused the pricing lookup to fail silently, defaulting costs to 0. Add fallback logic in getModel() that: - Only applies to google-vertex-anthropic provider - Searches for versioned models matching the unversioned ID pattern - Returns the latest version (reverse-sorted by date) - Maintains backward compatibility with versioned IDs - Falls back to standard error handling if no match found Fixes pricing computation so session costs are now calculated correctly instead of always showing $0.00 for google-vertex-anthropic models.

Why
When using the google-vertex-anthropic provider, model IDs like
claude-sonnet-4-5fail to match pricing data because models.dev stores them with date suffixes likeclaude-sonnet-4-5@20250929. This causes the pricing lookup to fail silently, defaulting costs to 0, resulting in sessions always showing $0.00 pricing.fixes #9565
What
Add fallback logic in the
getModel()function that:The fix is transparent to users - no configuration changes needed. Sessions now compute accurate costs from the resolved versioned model IDs.
Testing
Added 3 comprehensive tests:
All 69 provider tests pass.
