Go

OpenCode Go is a low cost subscription that gives you reliable access to popular open coding models, with the goal of making AI coding accessible to more people.

Note

OpenCode Go is currently in beta.

Go works like any other provider in OpenCode. You subscribe to OpenCode Go and get your API key. It’s completely optional and you don’t need to use it to use OpenCode.

Background

Open models have gotten really good. They now reach performance close to proprietary models for coding tasks. And because many providers can serve them competitively, they are usually far cheaper.

However, getting reliable, low latency access to them can be difficult. Providers vary in quality and availability.

Tip

We tested a select group of models and providers that work well with OpenCode.

To fix this, we did a couple of things:

1. We tested a select group of open 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 Go gives you access to these models for $10/month.

How it works

OpenCode Go works like any other provider in OpenCode.

1. You sign in to OpenCode Zen, subscribe to Go, and copy your API key.
2. You run the /connect command in the TUI, select OpenCode Go, and paste your API key.
3. Run /models in the TUI to see the list of models available through Go.

Note

Only one member per workspace can subscribe to OpenCode Go.

The current list of models includes:

• Kimi K2.5
• GLM-5
• MiniMax M2.5

The list of models may change as we test and add new ones.

Usage limits

OpenCode Go includes the following limits:

• 5 hour limit — $4 of usage
• Weekly limit — $10 of usage
• Monthly limit — $20 of usage

In terms of tokens, $20 of usage is roughly equivalent to:

• 69 million GLM-5 tokens
• 121 million Kimi K2.5 tokens
• 328 million MiniMax M2.5 tokens

You can view your current usage in the console.

Tip

If you reach a usage limit, you can continue using the free models available.

Usage limits may change as we learn from early usage and feedback.

Pricing

Below are the prices per 1M tokens.

Model	Input	Output	Cached Read
GLM-5	$1.00	$3.20	$0.20
Kimi K2.5	$0.60	$3.00	$0.10
MiniMax M2.5	$0.30	$1.20	$0.03

Use balance after limits

If you also have credits on your Zen balance, you can enable the Use balance option in the console. When enabled, Go will fall back to your Zen balance after you’ve reached your usage limits instead of blocking requests.

Endpoints

You can also access Go models through the following API endpoints.

Model	Model ID	Endpoint	AI SDK Package
GLM-5	glm-5	https://opencode.ai/zen/go/v1/chat/completions	@ai-sdk/openai-compatible
Kimi K2.5	kimi-k2.5	https://opencode.ai/zen/go/v1/chat/completions	@ai-sdk/openai-compatible
MiniMax M2.5	minimax-m2.5	https://opencode.ai/zen/go/v1/messages	@ai-sdk/anthropic

The model id in your OpenCode config uses the format opencode-go/<model-id>. For example, for Kimi K2.5, you would use opencode-go/kimi-k2.5 in your config.

Privacy

The plan is designed primarily for international users, with models hosted in the US, EU, and Singapore for stable global access.

Goals

We created OpenCode Go to:

1. Make AI coding accessible to more people with a low cost subscription.
2. Provide reliable access to the best open coding models.
3. Curate models that are tested and benchmarked for coding agent use.
4. Have no lock-in by allowing you to use any other provider with OpenCode as well.
