Zen gives you access to a curated set of AI models that OpenCode has tested and benchmarked specifically for coding agents. No need to worry about inconsistent performance and quality, use validated models that work.

Get started with Zen

Add $20 Pay as you go balance (+$1.23 card processing fee)

Use with any agent. Set monthly spend limits. Cancel any time.

What problem is Zen solving?

There are so many models available, but only a few work well with coding agents. Most providers configure them differently with varying results.

We're fixing this for everyone, not just OpenCode users.

  • [*] Testing select models and consulting their teams
  • [*] Working with providers to ensure they’re delivered properly
  • [*] Benchmarking all model-provider combinations we recommend

How Zen works

While we suggest you use Zen with OpenCode, you can use Zen with any agent.

  • [1]
    Sign up and add $20 balance - follow the setup instructions
  • [2]
    Use Zen with transparent pricing - pay per request with zero markups
  • [3]
    Auto-top up - when your balance reaches $5 we’ll automatically add $20

Your privacy is important to us

[*]

All Zen models are hosted in the US. Providers follow a zero-retention policy and do not use your data for model training, with the following exceptions.
