You can run DeepSeek on your Android phone with Off Grid AI Mobile (OGAM). It’s a small distilled DeepSeek R1 model, about 1 GB on an 8 GB phone or 5 GB on a 12 GB phone, and it answers with no internet and nothing uploaded.
The full DeepSeek V4.1 Flash doesn’t fit on any phone. If you want that one, skip to the full model.

Which DeepSeek fits on a phone?
DeepSeek’s newest model, DeepSeek V4.1 Flash, has 552B parameters. It only uses 8B to 16B of them per token, but every one still has to sit in memory. The official weights are about 510 GB, and the smallest community GGUF (unsloth’s UD-IQ1_S) is still about 233 GB. A flagship phone has 12 or 16 GB.
DeepSeek hasn’t released a small V4 or V4.1 model. The small DeepSeek models you can run are the R1 distills, built by teaching Qwen and Llama models to reason like DeepSeek R1. They’re MIT licensed and come straight from DeepSeek’s Hugging Face page.
| Model | Built on | Q4_K_M file | Phone RAM |
|---|---|---|---|
| DeepSeek-R1-Distill-Qwen-1.5B | Qwen2.5-Math-1.5B | 1.12 GB | 8 GB is fine |
| DeepSeek-R1-Distill-Qwen-7B | Qwen2.5-Math-7B | 4.68 GB | 12 GB |
| DeepSeek-R1-0528-Qwen3-8B | Qwen3-8B | 5.03 GB | 12 GB |
| DeepSeek V4.1 Flash | its own 552B design | about 233 GB at the smallest | doesn’t fit |
File sizes are from unsloth’s GGUF builds on Hugging Face.
Pick the 8B if your phone has 12 GB of RAM or more. DeepSeek-R1-0528-Qwen3-8B is the newest small model DeepSeek has put out, and on DeepSeek’s own model card it beats the plain Qwen3-8B at maths (86.0 against 76.0 on AIME 2024). The 1.5B is the one for 8 GB phones. It’s built on a maths model, so it’s good at working through a problem step by step and weaker at general chat.
To check your RAM, open Android Settings, then About phone.
How Off Grid AI decides what your phone can run
You don’t have to do the maths. OGAM’s model search hides anything too big for your phone and marks files that only just fit as Tight. On Android, a file up to about half your RAM runs well, and one up to about 62% is Tight. Past that, it isn’t offered.
So on an 8 GB phone you’ll see the 1.5B, and the 7B and 8B either show as Tight or don’t show at all. On a 12 GB phone, the 8B runs well.
Set it up
- Install OGAM from Google Play. It’s free, with no account.
- Tap Models in the bottom bar. Stay on the Text tab.
- Type deepseek r1 in Search models.
- Tap DeepSeek-R1-0528-Qwen3-8B on a 12 GB phone, or DeepSeek-R1-Distill-Qwen-1.5B on an 8 GB phone.
- Under Sizes, take Recommended. It’s the best file for your phone. Download it on Wi-Fi.
- Go to Home, tap Select Model and pick the DeepSeek model.
- Tap New Chat and ask something.
Turn on airplane mode and send another message. It still answers, because the model is running on your phone.
R1 models think before they answer, so you’ll see a reasoning step first. Give it a problem with a right answer, like “I earn 4,200 a month, rent is 1,450 and bills are 380. How much is left after 12 months?”, and check the working.
What about the full DeepSeek V4.1 Flash?
It can’t run on your phone, but your phone can talk to a server that runs it. There are two honest ways.
DeepSeek’s own app or API. It’s cheap and it’s the real model. DeepSeek’s API serves V4.1 Flash as deepseek-flash, from $0.30 per million input tokens at peak and half that off-peak. But DeepSeek’s privacy policy says it stores your data in China and may use what you type to train its models. You can opt out of training by emailing them.
OGAM can use the API so you keep one app. Go to Settings, then Remote servers, then Add manually. Put https://api.deepseek.com/v1 in Address, paste your DeepSeek key in API key and type deepseek-flash in Text model. Tap Test connection, then Add server. The app warns you that this server is on the public internet, and it’s right: those messages go to DeepSeek.
Off Grid AI Boost. Boost runs open models, DeepSeek V4.1 Flash included, on our own GPUs for one flat price from $4.99 a month for the first cohort. We don’t keep your prompts or train on them. It’s a pre-order today: API keys go out by January 2027, and usage limits for each plan aren’t published yet.
If something goes wrong
| Symptom | Check | Fix |
|---|---|---|
| The 8B doesn’t show in search | Your phone’s RAM | It’s too big for this phone. Take the 1.5B. |
| The model shows Tight | Other apps holding memory | It loads, but close heavy apps first or pick a smaller size. |
| The model won’t load | Free memory right now | Restart the phone and load it before opening other apps. |
| The answer rambles for ages | It’s a reasoning model | Ask a narrower question. The 1.5B is weakest at open chat. |
| The DeepSeek server test fails | The address and key | Use https://api.deepseek.com/v1 and a key with credit on it. |
