Notes

OpenCode Go documents that MiMo-V2.5 is available through the opencode-go provider, but the public Go docs mainly list models, usage limits, request estimates, and pricing. I could not find a provider-specific page that explicitly lists all request parameters accepted for opencode-go/mimo-v2.5.

The parameter list above is based on the upstream/OpenAI-compatible behavior observed for Xiaomi MiMo V2.5 and should be verified against the actual OpenCode Go route.

Important context:

• MiMo V2.5 is a reasoning model.
• It supports tool use according to upstream/OpenAI-compatible metadata.
• It supports multimodal input upstream (text+image+audio+video -> text), but this issue is only about configurable request parameters, not modality support.
• Please confirm whether reasoning / include_reasoning are accepted on the OpenCode Go route and what exact schema they use.

Scope check

• This is about configurable request parameters, not pricing, rate limits, endpoints, auth setup, or streaming.
