DeepSeek V4.1 Pro status: one official mention, no date, no id, no price
One mention, no date, id or price
"V4.1-Pro" appears exactly once, in the 2026-09-10 V4.1 Flash release note — and that sentence is about the v4-pro rerouting to Flash lasting until V4.1-Pro launches. The changelog later withdrew the rerouting. Today on QCode you still set deepseek-v4-pro or deepseek-v4.1-flash (DeepSeek's own id for the tier is deepseek-flash).

What official docs actually say
Official launch date
Release note, changelog and pricing page all give no date for V4.1-Pro.
Official model id
Neither /models nor the pricing table lists an id for V4.1-Pro.
Official mention
"This will continue until V4.1-Pro launches", in the 2026-09-10 release note.
Premise of that line
It relied on rerouting v4-pro to Flash — overridden by the 2026-09-10 changelog entry.
What this is
The 2026-09-10 V4.1 Flash release note first says that from 2026-09-14 04:00 UTC all deepseek-v4-pro requests will route to V4.1-Flash, then adds "This will continue until V4.1-Pro launches" — i.e. at that moment DeepSeek treated V4.1-Pro as the successor to that rerouting. The changelog's 2026-09-10 entry and the pricing footnote then state v4-pro continues after 2026-09-14 with unchanged billing, so the rerouting never took effect. V4.1-Pro itself still has no date, id or price.
What happened
The 2026-09-10 release note says "This will continue until V4.1-Pro launches". The changelog's 2026-09-10 entry says v4-pro continues with billing unchanged, withdrawing the rerouting plan.
Timeline
2026-08-13 DeepSeek-V4-Pro-0813 went GA — the only Pro id you can set today.
2026-09-10 the V4.1 Flash release note names V4.1-Pro once: "This will continue until V4.1-Pro launches".
The changelog's 2026-09-10 entry withdraws the rerouting plan from that same note; v4-pro continues, billing unchanged.
Confirmed vs caution
Officially confirmed
The pricing page confirms the two live ids and version names; the changelog's 2026-09-10 entry confirms v4-pro continues after 2026-09-14 with billing unchanged.
⚠️ Caution
"V4.1 Pro is imminent" is a reading of that one sentence taken out of context. The plan it belonged to was withdrawn by the changelog's 2026-09-10 entry (which states V4 Pro continues after 2026-09-14), and there is no official date, id or price — this page carries no schedule speculation.
Same vs differs
Same
Where all three official documents agree: the live ids are deepseek-flash and deepseek-v4-pro, versions DeepSeek-V4.1-Flash and DeepSeek-V4-Pro-0813 (on QCode, the V4.1 Flash tier is called deepseek-v4.1-flash).
Differs
Only the release note mentions V4.1-Pro, once, and its premise was withdrawn; the changelog and pricing page never mention it.
What to do
If you are waiting for V4.1 Pro: there is no date, id or price to align to, so keep it out of release plans and customer quotes. For the Pro tier today set deepseek-v4-pro (version DeepSeek-V4-Pro-0813) on QCode; for the newly released tier set deepseek-v4.1-flash (DeepSeek's own id is deepseek-flash).
On QCode
QCode sells deepseek-v4-pro (real 30-day traffic) and deepseek-v4.1-flash. V4.1 Pro is unreleased officially, so no id exists to add; availability follows /models.
FAQ
Is V4.1 Pro an official name?
It is a model name DeepSeek wrote once in the 2026-09-10 release note. Outside that sentence there is no official source, no id, no date and no price.
When does it launch?
Officially unstated. None of the three documents gives a date, so any specific date you see is not official.
How does it relate to deepseek-v4-pro?
The official sentence actually tied them together: the release note said the v4-pro rerouting to Flash would continue until V4.1-Pro launches. That rerouting was withdrawn by the changelog's 2026-09-10 entry, and the live Pro tier is still deepseek-v4-pro (DeepSeek-V4-Pro-0813), continuing after 2026-09-14 with unchanged billing — so the link only existed inside a plan that was never executed.
Does "until V4.1-Pro launches" still hold?
What fell through is the plan, not the sentence. The note says all deepseek-v4-pro requests will route to V4.1-Flash from 2026-09-14 04:00 UTC and adds "This will continue until V4.1-Pro launches" — so "This" refers to the v4-pro rerouting. Once the changelog's 2026-09-10 entry withdrew that rerouting, the sentence lost its premise, so it supports neither "V4.1 Pro is imminent" nor any deadline for the legacy flash-id routing.
Which id should I set?
For Pro, deepseek-v4-pro. For the tier released on 2026-09-10, deepseek-flash officially — deepseek-v4.1-flash on QCode. Always defer to /models.
How fresh is this page?
Conclusions are dated 2026-09-18. As soon as DeepSeek publishes a V4.1 Pro id or date, this page goes stale and needs a re-check.

Peak/off-peak and cache-hit rates for both live tiers.
This page separates three tiers: what official docs confirm about the live ids, the rumour and circulating schedule claims, and what stays unconfirmed — no official id, date or price. Beyond one passing mention, V4.1-Pro has no official information, so no capability claims and no leaked benchmarks.
