How to use with Minimax M2?

[failable]

Minimax supports Anthropic style API, how can I configure the API base url? Thanks.

We need to add support for minimax v1/messages as an upstream API. I have created an issue for this now.

But minmax supports both the /v1/chat/completions and /v1/messages API shapes. So if you configure your plano yaml like this

    model: minmax/MiniMax-M2.1
    base_url: https://api.minimax.io/v1
    provider_interface: openai
    access_key: $MINIMAX_API_KEY

Then you can curl a simple command to minmix like this via plano
