DeepSeek V4.1 Pro status: one official mention, no date, no id, no price
One mention, no date, id or price
As of 2026-10-19, DeepSeek V4.1 Pro has not been released: the 2026-10-17 changelog entry, the 2026-10-17 V4.1 Flash release note and the pricing page give no date, model id or price for it. The pricing page lists just two rows today — deepseek-flash (version DeepSeek-V4.1-Flash-1017) and deepseek-v4-pro (version DeepSeek-V4-Pro-0813). The name “V4.1 Pro” appears only in the 2026-09-10 V4.1 Flash release note, in a sentence saying deepseek-v4-pro requests will route to V4.1-Flash until V4.1-Pro launches; the changelog entry of the same day says V4 Pro API service continues after 2026-09-14 with the billing method unchanged. Today on QCode you set deepseek-v4-pro or deepseek-v4.1-flash (DeepSeek's own id for that tier is deepseek-flash).

What official docs actually say
Official launch date
As of 2026-10-19, the 2026-10-17 release note and changelog entry plus the pricing page 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 describes how long deepseek-v4-pro requests route to V4.1-Flash; the same-day changelog entry says V4 Pro continues after 2026-09-14 with the billing method unchanged. The 2026-10-17 changelog entry only covers the V4.1 Flash upgrade to DeepSeek-V4.1-Flash-1017 and does not mention V4.1-Pro either. As of 2026-10-19 both lines are still on the official pages.
What this is
The 2026-09-10 V4.1 Flash release note says: “Starting at 04:00 UTC on Sept 14, 2026, all deepseek-v4-pro requests will route to V4.1-Flash at V4.1-Flash rates. This will continue until V4.1-Pro launches.” The changelog's 2026-09-10 entry says: “we have decided to continue providing API services for DeepSeek V4 Pro after September 14, 2026, with the billing method remaining unchanged.” As of 2026-10-19 the pricing page still lists just two rows: deepseek-flash (version DeepSeek-V4.1-Flash-1017) and deepseek-v4-pro (version DeepSeek-V4-Pro-0813); the note (1) on the deepseek-flash row says the legacy names deepseek-v4-flash and deepseek-v4-flash-vision-exp are still accepted, but the corresponding models have been retired, their requests are served by the DeepSeek-V4.1-Flash-1017 model and billed at the Flash price. V4.1-Pro itself still has no date, id or price.
What happened
The 2026-10-17 changelog entry says V4.1 Flash has been upgraded to DeepSeek-V4.1-Flash-1017, the web and APP models were updated too, and the API calling method and pricing remain unchanged — simply use deepseek-flash to access the latest model. The release note of the same day is titled “DeepSeek-V4.1-Flash-1017: Wish-Driven Programming Made Real”. The only mention of V4.1 Pro so far is still the sentence “This will continue until V4.1-Pro launches” in the 2026-09-10 release note; the changelog's 2026-09-10 entry says V4 Pro API service continues after 2026-09-14 with the billing method unchanged.
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".
2026-10-17 DeepSeek upgraded V4.1 Flash to DeepSeek-V4.1-Flash-1017; the changelog says the calling method and pricing stay unchanged and deepseek-flash reaches the latest model, and the release note of the same day is titled “DeepSeek-V4.1-Flash-1017: Wish-Driven Programming Made Real”, which the vendor calls a Pareto improvement in performance and cost. The pricing page still lists just deepseek-flash and deepseek-v4-pro — no V4.1 Pro. Earlier, the release note said all deepseek-v4-pro requests route to V4.1-Flash starting 04:00 UTC on 2026-09-14; the changelog's 2026-09-10 entry says V4 Pro continues after 2026-09-14 with billing unchanged. Both lines stand.
Confirmed vs caution
Officially confirmed
The pricing page confirms two live ids and versions today: deepseek-flash (DeepSeek-V4.1-Flash-1017) and deepseek-v4-pro (DeepSeek-V4-Pro-0813), with no V4.1-Pro row among them. The changelog's 2026-10-17 entry confirms V4.1 Flash was upgraded to DeepSeek-V4.1-Flash-1017 with the calling method and pricing unchanged; the 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 sentence is about how long deepseek-v4-pro requests route to V4.1-Flash, while the same-day changelog entry states V4 Pro continues after 2026-09-14 with the billing method unchanged — the two lines stand side by side. The 2026-10-17 changelog entry and release note only cover the V4.1 Flash upgrade to DeepSeek-V4.1-Flash-1017; there is still no official date, id or price for V4.1 Pro. This page carries no schedule speculation.
Same vs differs
Same
Where the three official documents agree (the 2026-10-17 release note and changelog entry, the pricing page): the live ids are deepseek-flash and deepseek-v4-pro, versions DeepSeek-V4.1-Flash-1017 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, in a line about how long the v4-pro rerouting lasts, while the same-day changelog entry says V4 Pro continues after 2026-09-14 with billing unchanged; the changelog and pricing page never mention V4.1-Pro.
What to do
If you are waiting for V4.1 Pro: as of 2026-10-19 there is still 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 V4.1 Flash tier set deepseek-v4.1-flash (DeepSeek's own id is deepseek-flash; after DeepSeek's 2026-10-17 upgrade the calling method and pricing did not change; which version QCode serves follows /models).
On QCode
QCode sells deepseek-v4-pro (real 30-day traffic) and deepseek-v4.1-flash; DeepSeek's own model name is deepseek-flash, and the official changelog says the calling method and pricing did not change after the 2026-10-17 upgrade. V4.1 Pro is unreleased officially, so no id exists to add; availability follows /models. Not ready for a monthly plan? Pay-as-you-go Packs start at $4 for a one-time quota you use within 7 days.
FAQ
Is V4.1 Pro an official name?
It is a model name DeepSeek wrote once in the 2026-09-10 release note: V4.1-Pro. As of 2026-10-19 it appears in none of the 2026-10-17 changelog entry, the release note or the pricing page, and there is no id, date or price.
When does it launch?
Officially unstated as of 2026-10-19. Neither the 2026-10-17 release note and changelog entry nor the pricing page 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 deepseek-v4-pro requests would route to V4.1-Flash until V4.1-Pro launches. The same-day changelog entry says V4 Pro API service continues after 2026-09-14 with the billing method unchanged, and as of 2026-10-19 the pricing page still lists the Pro tier as deepseek-v4-pro (DeepSeek-V4-Pro-0813). Both lines stand side by side, and DeepSeek has not said how the two relate.
Does "until V4.1-Pro launches" still hold?
The sentence comes from the 2026-09-10 release note, but the same-day changelog entry says V4 Pro continues after 2026-09-14 with the billing method unchanged; both stand side by side, and DeepSeek has not said which one is in effect. 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. It therefore supports neither “V4.1 Pro is imminent” nor any deadline for the legacy flash-id routing.
Which id should I set?
For the Pro tier set deepseek-v4-pro. For the V4.1 Flash tier (released 2026-09-10, upgraded by DeepSeek on 2026-10-17) the official id is deepseek-flash; on QCode set deepseek-v4.1-flash, and which version it serves follows /models. Always defer to /models.
How fresh is this page?
Conclusions were last checked on 2026-10-19 (first checked 2026-09-18). As soon as DeepSeek publishes a V4.1 Pro id or date, this page goes stale and needs a re-check.

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 the one mention in the 2026-09-10 release note, V4.1-Pro has no official information, so no capability claims and no leaked benchmarks. Last checked 2026-10-19; official pages take precedence, and model availability is as listed on /models.
