DeepSeek V4 Flash Free returns FreeUsageLimitError on OpenCode Zen

Description

The deepseek-v4-flash-free model on OpenCode Zen consistently returns a FreeUsageLimitError when making requests through the OpenAI-compatible API.

Authentication works correctly, but the request is rejected by the provider with:

FreeUsageLimitError: Error from provider (Console): Rate limit exceeded. Please try again later.

I'm trying to use the free DeepSeek V4 Flash model through OpenCode Zen as a coding agent.

Plugins

none

OpenCode version

1.18.18

Steps to reproduce

Create/use an OpenCode Zen API key.
Send a request to:
https://opencode.ai/zen/v1/chat/completions
Use the model:
deepseek-v4-flash-free
Send a normal chat completion request.

Example:

curl -X POST "https://opencode.ai/zen/v1/chat/completions" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"deepseek-v4-flash-free","messages":[{"role":"user","content":"Say hello in one sentence."}]}'

This issue might be a duplicate of existing issues. Please check:

[BUG] Zen balance does not remove free usage cap; paid users still hit 200-request/free usage limit #33495: Zen balance does not remove free usage cap; paid users still hit FreeUsageLimitError with deepseek-v4-flash-free
[URGENT] Zen paid balance still hits FreeUsageLimitError / daily free usage limit. #33318: Zen paid balance still hits FreeUsageLimitError / daily free usage limit
error: Free usage exceeded, subscribe to Go #42013: Free usage exceeded error on DeepSeek V4 Flash Free via Zen (same error message, same model, same OS/terminal)

Still a problem

None of them are actually my fix, so Kindly help me know what and how the rate limit works.
