TL;DR

The issue can be resolved by verifying the model_name and litellm_params configuration to ensure they match the expected pricing model.

Guidance

  • Check the model_name in the log output to ensure it matches the expected model name vertex_ai/claude-opus-4-7.
  • Verify that the litellm_params configuration, specifically the model field, is set to the correct model name vertex_ai/claude-opus-4-7.
  • Review the pricing file to ensure that the price is correctly configured for the vertex_ai/claude-opus-4-7 model.
  • Investigate why the litellm is using the price from vertex_ai/claude-opus-4 instead of vertex_ai/claude-opus-4-7.

Notes

The issue seems to be related to a mismatch between the expected model name and the actual model name used by litellm. The provided log output shows that the model_name is vertex_ai/claude-opus-4-7-global, but the litellm_params configuration has a model field set to vertex_ai/claude-opus-4.

Recommendation

Apply workaround: Verify and correct the model_name and litellm_params configuration to ensure they match the expected pricing model. This should resolve the issue with the pricing not being displayed correctly.
