- title: Zen
- description: Curated list of models provided by OpenCode.
- ---
- import config from "../../../config.mjs"
- export const console = config.console
- export const email = `mailto:${config.email}`
- OpenCode Zen is a list of tested and verified models provided by the OpenCode team.
- :::note
- OpenCode Zen is currently in beta.
- :::
- Zen works like any other provider in OpenCode. You login to OpenCode Zen and get
- your API key. It's **completely optional** and you don't need to use it to use
- OpenCode.
- ---
- ## Background
- There are a large number of models out there but only a few of
- these models work well as coding agents. Additionally, most providers are
- configured very differently; so you get very different performance and quality.
- :::tip
- We tested a select group of models and providers that work well with OpenCode.
- :::
- So if you are using a model through something like OpenRouter, you can never be
- sure if you are getting the best version of the model you want.
- To fix this, we did a couple of things:
- 1. We tested a select group of models and talked to their teams about how to
- best run them.
- 2. We then worked with a few providers to make sure these were being served
- correctly.
- 3. Finally, we benchmarked the combination of the model/provider and came up
- with a list that we feel good recommending.
- OpenCode Zen is an AI gateway that gives you access to these models.
- ---
- ## How it works
- OpenCode Zen works like any other provider in OpenCode.
- 1. You sign in to **<a href={console}>OpenCode Zen</a>**, add your billing
- details, and copy your API key.
- 2. You run the `/connect` command in the TUI, select OpenCode Zen, and paste your API key.
- 3. Run `/models` in the TUI to see the list of models we recommend.
- You are charged per request and you can add credits to your account.
- ---
- ## Endpoints
- You can also access our models through the following API endpoints.

- You might notice _Claude Haiku 3.5_ in your usage history. This is a [low cost model](/docs/config/#models) that's used to generate the titles of your sessions.
- :::note
- Credit card fees are passed along at cost (4.4% + $0.30 per transaction); we don't charge anything beyond that.
- :::
- The free models:
- - GLM 4.7 is currently free on OpenCode for a limited time. The team is using this time to collect feedback and improve the model.
- - MiniMax M2.1 is currently free on OpenCode for a limited time. The team is using this time to collect feedback and improve the model.
- - Big Pickle is a stealth model that's free on OpenCode for a limited time. The team is using this time to collect feedback and improve the model.
- <a href={email}>Contact us</a> if you have any questions.
- ---
- ### Auto-reload
- If your balance goes below $5, Zen will automatically reload $20.
- You can change the auto-reload amount. You can also disable auto-reload entirely.
- ---
- ### Monthly limits
- You can also set a monthly usage limit for the entire workspace and for each
- member of your team.
- For example, let's say you set a monthly usage limit to $20, Zen will not use
- more than $20 in a month. But if you have auto-reload enabled, Zen might end up
- charging you more than $20 if your balance goes below $5.
- ---
- ## Privacy
- All our models are hosted in the US. Our providers follow a zero-retention policy and do not use your data for model training, with the following exceptions:
- - GLM 4.7: During its free period, collected data may be used to improve the model.
- - MiniMax M2.1: During its free period, collected data may be used to improve the model.
- - Big Pickle: During its free period, collected data may be used to improve the model.
- - OpenAI APIs: Requests are retained for 30 days in accordance with [OpenAI's Data Policies](https://platform.openai.com/docs/guides/your-data).
- - Anthropic APIs: Requests are retained for 30 days in accordance with [Anthropic's Data Policies](https://docs.anthropic.com/en/docs/claude-code/data-usage).
- ---
- ## For Teams
- Zen also works great for teams. You can invite teammates, assign roles, curate
- the models your team uses, and more.
- :::note
- Workspaces are currently free for teams as a part of the beta.
- :::
- Managing your workspace is currently free for teams as a part of the beta. We'll be
- sharing more details on the pricing soon.
- ---
- ### Roles
- You can invite teammates to your workspace and assign roles:
- - **Admin**: Manage models, members, API keys, and billing
- - **Member**: Manage only their own API keys
- Admins can also set monthly spending limits for each member to keep costs under control.
- ---
- ### Model access
- Admins can enable or disable specific models for the workspace. Requests made to a disabled model will return an error.
- This is useful for cases where you want to disable the use of a model that
- collects data.
- ---
- ### Bring your own key
- You can use your own OpenAI or Anthropic API keys while still accessing other models in Zen.
- When you use your own keys, tokens are billed directly by the provider, not by Zen.
- For example, your organization might already have a key for OpenAI or Anthropic
- and you want to use that instead of the one that Zen provides.
- ---
- ## Goals
- We created OpenCode Zen to:
- 1. **Benchmark** the best models/providers for coding agents.
- 2. Have access to the **highest quality** options and not downgrade performance or route to cheaper providers.
- 3. Pass along any **price drops** by selling at cost; so the only markup is to cover our processing fees.
- 4. Have **no lock-in** by allowing you to use it with any other coding agent. And always let you use any other provider with OpenCode as well.
