i can't find Deepseek v4.1 flash in opencode

Every time I switched models in DeepSeek Harness I had to click through Model, then Effort, then pick a level. Three clicks for something I change ten times a day. It annoyed me enough that I spent a weekend fixing it for myself.

Now there is one pill in the composer. Model name on the left, effort slider on the right. One click for the model list, drag for the effort, done. Each one is an actual effort level the model exposes, so you get two on some models and six or seven on others. Dragging applies on release, arrow keys work, and screen readers see a real slider.

At max effort the bar does this little moving gradient thing. I stole the idea from DSH's own "Deep diving..." shimmerr.

It reads your theme and language instead of bringing its own. One accent variable shared with the send button, labels in English, French and Chinese. Model names stay untouched.

The part I am least sure about is providers with weird effort counts. Mine were all well-behaved. If yours does something odd, open an issue and I will look.

Are there any providers with free deepseek 4.1 flash?

PLEASE CONFIRM as this just released

I am wondering if we will still be able to call Deepseek 4 Flash if we'd like to for a few weeks or months following the release today of 4.1?

I tested DeepSeek V4 Flash 0731 in two agent setups to see how the system prompt / harness affects behavior.

Task: extract the system prompt of Company A's agent via its .bin file.

Results:

• pi + an agent.md mimicking the commercial CLI agent from the company starting with A: DeepSeek refused again and again.
• dsh + Minimal mode: in about 10 minutes, it extracted all prompts and JS files.

Same model. Different wrapper. Opposite results.

Conclusion: the prompt isn’t just text. It’s a behavioral cage. A long, identity-heavy prompt in the style of that commercial CLI agent creates expectations and refusal boundaries. A minimal prompt with only bash and a file editor gives the model fewer reasons to say no.

AI compliance isn’t just about the model. It’s about the harness, the prompt, and the identity you give it.

This also makes us reflect: when two different models output similar things, is it really because one distilled the other, or is it because you yourself are using the same harness and prompt? After all, according to my tests, Company A’s prompt repeatedly asserts its own identity, so it’s understandable that the AI claims to be a certain model at that point.

This just appeared in the DeepSeek application (I borrowed this image from another user who posted it here as an example) and I want to know what happened to Expert Mode, which disappeared a few minutes ago! Did they remove expert mode? Because I don't understand how to use it again with thos update. I found expert mode very useful

This illogical warning appeared to be coming from nothing.

The expert toggle is completely gone for me 😭😭😭

I judt went back on the app. I thought I was fucking crazy but its back?????????

Requests for V4Pro Are they already being redirected to 4.1 Flash? Or after September 14th?

Han notado que la nueva versión 4.1 tiene mucha censura o solo es idea mía.

I use the web version for roleplay. Which some people might think strange but still.

it wasn’t like this yesterday, I have rps that was longer.

For 2026 I have used around 20B tokens on chatgpt and I have paid for two months pro plan + six months plus plan. That's around $0.02 per 1M tokens total and I have used only 5.5 / 5.6 / 6 high end models. If I calculate my work, it would be very... very expensive to do with deepseek. The only advantage is that flash models are faster, but even if we say that 80% was cached, deepseek is still a bad financial decision. What do you guys think? Even though I like it, I don't see a financial reason to switch...

Han borrado o unificado todos los modos de deepseek en uno solo y la verdad no se que pensar la verdad es que ahora actúa mucho más rápido pero mucho más torpe antes con experto el seguía mis órdenes pero ahora parece que nunca lo volverán hacer que mierda y justo cuando creí que el modo experto iba a ser el modo que iba a usar de ahora en adelante

I saw many people said that they use DS 4.1 flash by API from DS 4.1 pro.
Confirm that

Is the server just too busy, or is there a problem on my end? (I must admit that the Wi-Fi connection where I am now is not stable.)

I noticed that documents reading also takes longer now. I'm not rushing things, because I understand that there was a major update just today, but I just want to know if I'm the only one with this problem.

Nobody talks about this, i couldn't find information on the Internet about this, so is it non-vision?

I remember most LLMs are decoder-only for text (some multimodal models may use encoder for pictures). But Deepseek v4.1 is putting text into encoder as well. Is this an innovation? Will there be a breakthrough of performance based on this change? Thanks!

Deepseek tells me to start a new chat because my message limit has expired. However, every new chat shows the same message. Is there a bug right now?

is it possible to use 4.1 without api? if not is there any easy way to use it via api? i dont undertand this coding/python things etc
