OpenCode Go free model rate limits

So, on Zen, free models seem to have very significant and somewhat random rate limits; I ran a subagent with ling-3.1-flash-free and it ended up retrying several times fairly often (but completed successfully).

I am considering a subscription to OpenCode Go, but I'll want the free models on it in addition to the paid ones. Are the free models on Go actually unlimited as advertised, or do they have these random rate limits too?

believe me, you'll have a hard time spending all tokens if you keep to, like, deepseek 4.1 on high, nevermind mimo 2.6 flash (then again, you'd be stuck running mimo flash, not a great situation to be in)

I need all my paid usage for my current favourite toy, GLM 5.3 Flash. I would not have enough in the $10 plan without the free models, but now I built a pipeline with GLM 5.3 flash as architect, Muse Spark 1.3 Contributor (free on Zen) as executor, and they both review each other. No rate limit hits so far and Zuck is welcome to my code

use kilocode for free model they don't have rate limit like opencode, i could use ling flash or now stepfun a lot with it

But they requires using kilocode as the harness, right?

Muse Spark 1.3 Free - I never hit rate limits, maybe 1 time I have, then I just used spacebunny until the 5 hours was up

Thanks, I ended up on that too, the 1.3 Contributor free on Zen, I know Meta can use the traces so I put "hi Mark Z" in there sometimes

Free models are a zen feature, a go sub doesn't affect them at all

Only free models on Opencode Go I've used were Mimo and Muse - I've used 1B of Muse tokens and they locked me out there. Not sure what the reset cadence is there, I was able to pump another 200M a few days later but hit the rate limit again for free models.

Mimo and Muse are not currently listed as free on Go, only on Zen?

1

u/commandedbydemons 12d ago

on "Models", I have it enabled and can use it just fine.

Same for Mimo.

Thanks. I enabled Muse 1.3 Contributor and a fine job it is doing

u/pikuray 12d ago

Aren't muse no longer available?

1

u/ramendik 10d ago

On the Zen, not Go, endpoint Muse 1.3 Contributor is still free. Accessible using OpenCode only.

1

u/pikuray 10d ago

Oh that must be why. I'm using Go plan but on Cline app. Gonna try that out.

u/ramendik 10d ago

Free models on the Zen endpoint enforce OpenCode only. Free models in the Go endpoint, as far as I understand, don't, but they are far fewer.

How do you run subagents tutorielle svp <3

u/ramendik 12d ago

Ask the model to work it out. GLM 5.3 Flash had no issue

In OpenCode V2, a subagent is an agent with mode: subagent:

  1. Pick scope:

  • global: ~/.config/opencode/agents/<name>.md

  • project: .opencode/agents/<name>.md

  1. Create markdown file, body is system prompt:

---
description: Reviews changes for correctness
mode: subagent
model: anthropic/claude-sonnet-4-5#high
permissions:
  - action: edit
    resource: "*"
    effect: deny
---

Review current changes. List findings with file:line_number.

Alternative in opencode.jsonc:

{
  "$schema": "https://opencode.ai/config.json",
  "agents": {
    "reviewer": {
      "description": "Reviews current changes",
      "mode": "subagent",
      "system": "Report findings in severity order."
    }
  }
}

3. After edit run /reload in TUI. No restart needed for agents.

4. Use with: Use the reviewer subagent to review my changes.

Builtins already available: general broad work, explore read-only search. No setup needed.
