Greptile Summary

This PR adds the cache_creation_input_token_cost_above_1hr field (6e-06) to vertex_ai/claude-sonnet-4-6 and vertex_ai/claude-sonnet-4-6@default in the model pricing JSON. The value is consistent with analogous models (azure_ai/claude-sonnet-4-6, azure_ai/claude-sonnet-4-5, claude-3-7-sonnet-20250219, all set to 6e-06), representing a 1.6× multiplier over the standard cache-write cost.

• The base claude-sonnet-4-6 (Anthropic provider, line 8902) and all Bedrock variants (anthropic.claude-sonnet-4-6, us.anthropic.claude-sonnet-4-6, eu.anthropic.claude-sonnet-4-6, au.anthropic.claude-sonnet-4-6) appear to be missing cache_creation_input_token_cost_above_1hr — if that cache tier applies to those providers, a follow-up PR would be needed.

Confidence Score: 4/5

Safe to merge; minimal, targeted pricing-only change with correct values.

Only P2-level observation: the direct Anthropic provider and five Bedrock variants are missing the same field, but that omission pre-dates this PR and is out of scope here.

No files require special attention.
