OpenCode Go + DeepSeek
Flash for volume, Pro for hard agents
This page exists for the exact query “opencode go deepseek”. The name deepseek-v4-flash still resolves, but DeepSeek retired the 0731 build on 2026-09-10 and its requests are answered by V4.1-Flash. Read the model object and the knowledge cutoff the API returns to tell which build you actually get.
Updated 2026-09-20
Highlights
opencode-go/deepseek-v4-flash
Docs estimate ~31,650 req/5h (63,300 with 2× promo).
opencode-go/deepseek-v4-pro
~3,450 req/5h estimate. Use when Flash fails.
Also listed
Official X: Flash on Free tier too, with tighter limits.
Monthly (as of fetch)
Go privacy table: DeepSeek ZDR is renewed monthly. Fetched 2026-08-30, official text still said valid through August 31, 2026. The date moves; use the docs at the time.
Go’s DeepSeek lane
Pair this with the 0731 / 0813 model guides: this page stays operational (ids, caps), those pages own benches — and the 0731 one is now a historical record.
Why it is trending
Some GitHub issues report that context on the Go lane was cut from 1M to 200k, or that the build served was not the 0731 generation. These are community reports; OpenCode has published no statement on them. One thing is settled: since 2026-09-10 requests to deepseek-v4-flash are answered by V4.1-Flash and billed at the Flash price. The most reliable check on your actual setup is still the model object the API returns.
Timeline
2026-07-31: the official changelog records the 0731 public beta. OpenCode never published a separate date for adding it to Go + Free, so the community logs it against this beta. That build was retired on 2026-09-10.
2026-08-30 fetched opencode.ai/docs/go: ids per lane, dollar prices and the ZDR footnote on the DeepSeek row.
The privacy-table footnote still said DeepSeek ZDR valid through August 31, 2026. Whether that line was rewritten after 08-31 is not restated.
Confirmed vs caution
Confirmed
Ids, estimate table, ZDR footnote, official X.
Caution
Two things are not guaranteed: OpenCode has never promised that every Go or Free request lands on one specific DeepSeek build, and there is no one-click Claude Code integration. Since 2026-09-10 deepseek-v4-flash resolves to V4.1-Flash; what you actually get is whatever the API's model object reports.
How to choose
Volume on a $10 cap
Flash. Watch the 2× footnote.
Hard agent, still on Go
Pro, knowing the 5h estimate collapses to thousands not tens of thousands.
How to use it

On QCode
OpenCode Go is not a QCode product. If you would rather call official DeepSeek directly instead of going through a subscription lane, QCode currently lists deepseek-v4-flash and deepseek-v4-pro on /models.
FAQ
Which Flash build does Go actually serve?
Officially the new Flash was added. Verify cutoff on your account.
Free vs Go Flash?
Same family, different limits/queues/maybe ctx. Paid Go is the reliability pitch.
Pro on Go worth it?
Only for tasks Flash fails — it eats the $12/5h cap fast.
1M context?
Official Flash/Pro are 1M. Some free routes were reported reduced — community.
ZDR after Aug 31?
As of the 2026-08-30 fetch, the opencode.ai/docs/go#privacy footnote still reads: “DeepSeek: ZDR agreement is renewed monthly. The current agreement is valid through August 31, 2026.” Whether that sentence was rewritten after 2026-08-31 is not restated on the docs page; this page does not claim the agreement was renewed or that it has already lapsed.
Use official DeepSeek instead?
If you need peak/off-peak official pricing and 2500/500 concurrency, yes.
