OpenCode Go: mimo-v2.5 returns 402 "Insufficient account balance" despite active subscription

[amirasyraf]

Description

When using mimo-v2.5 (model ID: mimo-v2.5-pro) via the opencode-go provider, every request fails with HTTP 402 and the following error:

{"error":{"code":"402","message":"Insufficient account balance","type":"insufficient_balance"}}

This is incorrect — my account is actively subscribed to OpenCode Go with usage well within limits (Rolling: 25%, Weekly: 20%, Monthly: 10%).

Other models are working fine, just not mimo models.

The request is hitting: https://opencode.ai/zen/go/v1/chat/completions

Relevant log line:
ERROR service=llm providerID=opencode-go modelID=mimo-v2.5-pro error={"error":{"name":"AI_APICallError","url":"https://opencode.ai/zen/go/v1/chat/completions","statusCode":402,"responseBody":"{\"error\":{\"message\":\"Provider returned error","code":402,"metadata":{"raw":"{\"error\":{\"code\":\"402\",\"message\":\"Insufficient account balance\",\"type\":\"insufficient_balance\"}}"}}}"}

Plugins

Steps to reproduce

1. Have an active OpenCode Go subscription
2. Select mimo-v2.5 as the model (opencode-go provider)
3. Send any message
4. Observe: request fails immediately with "Provider returned error"
