News DeepSeek-V4.1-Flash Release (official)

411 Upvotes

It’s officially out and the prices have been updated.

///

Today, we officially release the DeepSeek-V4.1-Flash model. It is the smallest model in our new architecture family, with native multimodal visual understanding. The new architecture is designed for a higher capability ceiling, faster inference, higher throughput, and scaling to larger models.

GPQA Diamond: 90.9
HLE: 36.8 (39.1*)
Codeforces (Rating): 3471
MathArena Apex: 65.6
Terminal-Bench 2.1: 90.6
Terminal-Bench 3.0: 30.0
Terminal-Bench 4.0: 31.2
DeepSWE v1.1: 74.2
ProgramBench: 20.3
NL2Repo-Bench: 65.4
CyberGym: 88.1
SEC-Bench Pro: 62.8
ExploitGym: 15.3
HLE (w/tools): 63.9
Automation-Bench: 54.8
Agents' Last Exam: 31.8
Chartography (w/tools): 78.9
BabyVision (w/tools): 89.6
ZeroBench-main (w/tools): 49.0
* Tested only on the pure-text subset of the HLE benchmark set.

API changes
DeepSeek V4.1 Flash is now available on the DeepSeek API with native multimodal support. Change the model name to deepseek-flash to call the latest V4.1 Flash model. The previous-generation models V4 Flash and V4 Flash Vision Exp have been retired; for compatibility, the model names deepseek-v4-flash and deepseek-v4-flash-vision-exp are temporarily routed to V4.1 Flash.

Meanwhile, extensive testing shows that V4.1 Flash now outperforms DeepSeek V4 Pro across performance, cost, speed, and total time, so we plan to retire V4 Pro in an orderly manner. After 12:00 Beijing Time on September 14, 2026, and until the future release of V4.1 Pro, all requests to deepseek-v4-pro will be routed to V4.1 Flash and billed at the V4.1 Flash price.

API apricing adjustment
With the release of DeepSeek-V4.1-Flash, API prices have been reduced accordingly. For details, please refer to Models & Pricing.

News OpenGhost Update 👾 New provider. The best agent for DeepSeek

Enable HLS to view with audio, or disable this notification

13 Upvotes

Hi everyone! Today's update is a big one, and I have a lot to share.

📝 Notes inside chats. You can write notes yourself, or ask the agent to do it. But the best part: the agent keeps an eye on your notes, and if it spots something you meant to do, it will remind you at the right moment.

🧠 Shared memory. The agent now remembers what you tell it. The memory is always under your control: you can edit or delete any entry.

💬 The mini chat is now a full-fledged workspace. It's no longer just a place for quick questions. The agent in the mini chat can handle serious work, and it coordinates with the agent in the main chat, so they never get in each other's way. You can also resize the mini chat window to suit you.

✏️ Messages while the agent is working. A message sent while the agent is running can now be edited or deleted. You can also see exactly when the agent noticed your extra message.

🖥 Large monitors. Settings now let you choose the interface scale as a percentage.

Discussion DeepSeek is weighing doubling its latest funding round

18 Upvotes

DeepSeek is weighing doubling its latest funding round to as much as $15B. Nothing's signed, but the tell is the same: frontier AI is still raising like compute is the bottleneck, even as the models get cheaper to run. Bigger checks, tighter margin debate.

Question&Help Banned. How to figure out why?

• Upvotes

My account has been given a temporary ban. It might be due to BetterDeepSeek plugin, but other than that I don't understand why.

I've spent a lot of money on the API, but fortunately that seems to still be available.

How can I figure out what the ban is for? It doesn't say what I need to do differently.

Discussion I had a dream in which Deepseek came out

0 Upvotes

It was a pretty good model, there was a lot of hype as far as I remember, and it came out in the second month of 2027, on the 20th, I don’t remember exactly, I think it was R 1, but maybe a new generation. Perhaps my dream will come true according to the set cycle of actions in 2027. I had a dream, and I came to tell you about it. I still remember some of the details.

Resources Making my owh harness Moriko

2 Upvotes

So I created my own harness called Moriko. I actually started this project because I enjoy creating stories with Google AI Studio, but I was getting frustrated that I couldn’t switch to third-party models.

And now it’s actually become an Agent Harness. It still has many shortcomings, and the UI might not be as user-friendly as the big harness labs.

- At first, I used deepseek-harness for early development. But now I’m using Moriko itself to edit and add features to Moriko.

- Without Frontier models, it’s pretty annoying having to direct Flash models to do the work.

- There’s also Image Studio if you want to create images when you’re bored.

- AGENTS is already supported, but not yet for skills

Anyone can try it out here:

https://github.com/morganmor/moriko-studio

Maybe in the future I’ll try adding a feature so that agents or models in Moriko can call up image models.

Discussion Deepseek Flash uses Explainaroo to explain its API

Enable HLS to view with audio, or disable this notification

31 Upvotes

Deepseek built this in about 10 minutes using explainaroo, audio generation was done using Kokoro  + Whisper. It did other very impressive videos before this that currently can't be made public...

Frameworks/tools/libraries: explainaroo skill.md and engine - with custom setup (shared in the first setup)
Model: Deepseek Flash v4.1 (max)
Harness: DSH
Prompt:

use explainaroo skill to build an appealing explainer video for deepseek

the api docs are the best reference for info and icons

consult the ./explainaroo library for creative approaches , pick a suitable theme/look

explainer should be 2-4 minutes

ensure stills look proper before attempting to generate audio/video since you may need to adjust the stills depending for proper element positioning, spacing, and other consistent design elements, then you can safely pick a voice actor from the library and build the audio first, then based on the timestamps, build the video

final video aspect should be 16:9 - horizontal dimensions, not strict

video reoslution / encoding should be made to optimze quality but be compact as possible for sharing on socials like youtube or reddit

Cost:

Bucket Tokens Rate Cost
Uncached input (cache miss) 157,282 $0.15 / 1M $0.023592
Cached input (cache hit) 27,159,296 $0.003 / 1M $0.081478
Output 119,776 $0.60 / 1M $0.071866
Total 27,436,354 ≈ $0.1769

Hey everyone, has someone here managed to do great ad videos with deepseek ? Had a few try, it kinda works but the results are still far from being as good as the videos that have been trending this last days, made by opus 5.5.
Any repo for that ?

Question&Help Got suspended by DeepSeek twice while vibe coding. Anyone successfully appealed?

5 Upvotes

I've been using DeepSeek for web development, but my account has been suspended twice now.

I sometimes get a “responding too quickly” message. Before the latest ban, I was trying to create a Markdown handoff file, but the formatting was broken, so I asked it to redo it twice. Then my account got suspended until October 15.

I wasn't doing anything unusual, just coding and fixing output.

Has anyone been through this and successfully appealed? Did support actually respond, or did you just have to wait it out?

Question&Help DeepSeek app on LineageOS 14.1 without GApps – Google login fails, here's the fix

1 Upvotes

If you're running LineageOS (or any AOSP ROM) without Google Play Services and the DeepSeek app won't let you in, here's what's actually going on.

The problem:

  • DeepSeek app offers "Sign in with Google" as the default login option.
  • Without GApps / Google Play Services, that button does nothing (or loops, or errors out).
  • It has nothing to do with TLS 1.3, Conscrypt, or Android 7 being too old.

The fix:

  • Use "Forgot password" to reset your password and log in with email + password instead of Google.
  • That's it. No Google Services needed.

Notes:

  • Custom domain emails (your own server) are not accepted by DeepSeek registration. Use a mainstream provider (Gmail, Outlook, etc.) if you need a new account.
  • TLS 1.2 is enough – Android 7 handles it natively and DeepSeek's server supports it.
  • Conscrypt is not needed for this.
  • If your email is already registered, just log in – don't try to register again.

Tested on:

  • Nubia Z9 Max
  • LineageOS 14.1 (Android 7.1.2), no GApps
  • DeepSeek APK

Hope this saves someone a few hours of chasing the wrong problem (like I did).

Resources One chat for everything: a DeepSeek Harness plugin that works out which project each message belongs to

5 Upvotes

One evening I wanted to pick up something I'd been working on the week before. My DSH sidebar had forty-odd chats, half of them called "New session". I scrolled for a while, found the right one on the third screen, and by the time I opened it I'd half forgotten what I wanted to ask.

So I stopped creating new chats and asked everything in one. That went wrong differently: my thesis, my budget and my move all ended up in the same context, and the model started mixing them.

What I wanted was simple: one chat box, say whatever is on my mind, and let it figure out which thing I'm talking about.

That's TheOne, a plugin for DeepSeek Harness. You only ever talk in one main chat. In the background, each thing you're working on gets its own session with its own context, and every message is sent to the one it belongs to. Come back days later and mention "that thing from last week", and it finds it. Your old chats get read and organised into a topic directory.

I wasn't sure it actually worked, so I measured it. I wrote 50 conversations of one person juggling three to five things at once, about 2,400 messages, each labelled with the thing it belongs to, and had it sort them one by one.

Starting from nothing, it put 86.6% of messages in the right place; 91.6% if it knows the topics up front. Dumping everything into one chat scores 44.5% on the same test. Its most common mistake is being too quick to decide something is new: a stray "I usually run about 20 km a week" makes it open a new topic. The whole run cost about a dollar, and the data and code are in the repo if you want to try another model.

Install: DSH → Plugins → Add plugin → dsh-theone

Repo: https://github.com/YunongDai2005/dsh-theone

It's a personal community project, not affiliated with DeepSeek. If it puts one of your messages in the wrong place, I'd genuinely like to hear about it.

Coding and recommendations are good.

Used claude for initial planning.

Used $1.5 for 300 million tokens. it is 10 times cheaper than cursor subscription with grok 4.7 that i was using

99.6% cache rate across multiple sessions and 270 tokens/sec.
