I use deepseek-v4-flash on Hermes agents, with no glm-5, but glm-5 is being used according to the Usage page

Description

Summary

I use deepseek-v4-flash for Hermes agents and have no glm-5 configured.
But the Usage page shows both glm-5 and deepseek-v4-flash being used.

Expected

Only configured models should be shown, and the Usage page should show the exact model used, not unused models.

Actual

The Usage page shows glm-5, and it is not clear which configured key is mapped to it.

Environment

• Provider: opencode go
• Model used: deepseek-v4-flash
• Agents: Hermes agents
• glm-5: not used

Additional Context

This behavior is surprising and appears to indicate a model routing issue.

Plugins

No response

OpenCode version

opencode go

Steps to reproduce

1. Configure Hermes agents to use only deepseek-v4-flash.
2. Send a normal request through the Hermes agents.
3. Open the Usage page on opencode.ai.
4. Observe glm-5 appears as used, even though only deepseek-v4-flash is configured.

This issue might be a duplicate of existing issues. Please check:

• Plugins should not be able to use models I never explicitly configured #22541: Similar report of unexpected models being used that the user did not explicitly configure — while that issue focuses on plugin behavior, both describe models appearing in usage/billing that were not intentionally selected by the user.
