[Feature]: Zen as provider for all agents

[thepatchworkapp]

Prerequisites

• I have searched existing issues and discussions to avoid duplicates
• This feature request is specific to oh-my-opencode (not OpenCode core)
• I have read the documentation

Problem Description

I am subscribed to the Zen Black plan with OpenCode, and don't have subscriptions to any other providers.

Can you please add a feature that will use the recommended models for all agents, but use Zen for auth instead of the model providers?

If I run the installer with all of the provider options set to "no", I get this:

bunx oh-my-opencode install --no-tui --claude=no --chatgpt=no --gemini=no

...

Proposed Solution

Perhaps in the future I could do:

bunx oh-my-opencode install --no-tui --claude=no --chatgpt=no --gemini=no --zen=yes

all the models are configurable via json - read the README (or have an agent do so), I was able to update the models all to use my OpenCode Black subscription.

[Aaalice233]

I want to use Minimax M2.1 from OpenCode Zen as a backup model, but I simply cannot find the corresponding model ID, so I have no idea what to configure in the oh-my-opencode.json file...

[Aaalice233]

I finally found it. Honestly, I don't understand why the default model ID is so hard to locate. Maybe I just wasn't careful enough...

they publish all of the model names: https://opencode.ai/zen/v1/models

This reply for my preference. How do you find minimax-m2.1-free versus glm-4.7-free? I found much superior just using it with near stock opencode but trying omo again im gonna see what glm is like. mimo 2.1 is sick from work i did with it before learning about multi antigravity and gemini auth plugins.

I think M2.1 has basically reached Sonnet-level performance. Other than lacking image recognition support, it’s actually pretty good. I’m currently using the OMO plugin too: for reasoning-related agents, I use M2.1; for agents handling image recognition, retrieval and document tasks, I configure them to run Gemini 3 Flash and Gemini 3 Pro via the Antigravity Auth plugin. (The Opus model on Antigravity isn’t very stable—after the global quota was reached last time, Google cut the quota for the Claude series.) For me, this is a fairly stable combination.

[thepatchworkapp]

Many things are configurable via json, but I still think this is a useful option.

In subsequent releases, if the base package changes the model used for a specific agent, that new config won't overwrite the manual config and thus is not what I want.

[justsisyphus]

Acknowledged. While manual JSON configuration is a workaround, adding a first-class --zen provider option to the installer and configuration logic is a valid enhancement. This would allow users with Zen subscriptions to easily use recommended models via Zen authentication without manual maintenance of model IDs. We'll keep this issue open for implementation.

[douglascamata]

+1 for this. I don't want to manually configure aaaaaall agents to use the Zen provider. I just want to flip a single master switch to make Zen my default provider, so that I don't need to update my settings whenever some new agent appears using some model outside of Zen.

Considering that the OpenCode Black subscription exists, we should be able to get everything from a single provider for a good price.
