Free Usage Limit Exceeded on First Request (DeepSeek V4 Flash Free / OpenCode Zen) #42128
Description
Description
Issue: Free Usage Limit Exceeded on First Request (DeepSeek V4 Flash Free / OpenCode Zen)
Summary
The model DeepSeek V4 Flash Free (provider: OpenCode Zen) returns a "Free usage exceeded" error immediately, despite no prior requests having been made under this account/session.
Environment
- Client: OpenCode (terminal-based AI coding CLI)
- Model: DeepSeek V4 Flash Free
- Provider: OpenCode Zen
- Agent config: Claude-Like-V2
Steps to Reproduce
- Open OpenCode with the
Claude-Like-V2agent configuration. - Select
DeepSeek V4 Flash Freeas the active model. - Send a minimal test message (e.g.
hai). - Observe the response.
Expected Behavior
The request should be processed normally, since this is the first request sent on the free tier and no prior usage has been recorded.
Actual Behavior
The request immediately fails with the following error:
Free usage exceeded, subscribe to Go [retrying attempt #2]
The system continues to retry automatically but does not succeed.
Evidence
- Screenshot attached showing the error message displayed directly after the first message was sent, with no prior activity in the session.
Impact
- Blocks any usage of the free tier for this model.
- Prevents testing/development workflows that rely on the free quota.
- Retry attempts do not resolve the issue, resulting in a stuck state.
Possible Causes
- Free-tier quota may be shared/pooled across all users and already exhausted server-side (not user-specific).
- Incorrect quota tracking or reset logic on the provider's backend.
- Session/account misidentification causing the quota check to reference a different (already-exhausted) usage record.
Suggested Next Steps
- Verify quota reset timing and whether the free tier is per-user or globally shared.
- Check backend logs for the account/session to confirm zero prior usage before this request.
- Provide clearer error messaging distinguishing "global quota exhausted" from "user quota exhausted."
Additional Notes
No workaround currently available other than switching to a paid plan (Go) or a different model.

i have the same problem

This is probably happening with any Zen model, since I use the MiMo v2.5 model and I'm having the same problem... and it's probably related to the CLI, because when I ask it to keep writing* the code, it continues to work normally...

i actually tried it with 9router and omniroute, and cli and desktop every one of them got the same problem, on the tool calls always happend on the normal text messages the issue happend after 4 request

I hope this limitation wasn't intentionally set; I tried searching for a possible solution but couldn't find one..

I’m experiencing the exact same issue. I purchased the OpenCode Go subscription, but my account still shows “Free usage exceeded” also when i use free model deepseek

Hopefully it will be fixed quickly. 😮💨
