You want a local AI model that runs well on your Android phone, and you do not want to read quantization tables to find it. Off Grid AI Mobile (OGAM) now opens the Models screen with three picks worked out for your phone's RAM: Fast, Balanced and Best. Tap one, it downloads, and it becomes the model your chats use. After the download, the model runs on your phone's CPU, GPU or NPU, and nothing you type is sent anywhere.
The same three picks are on the Image tab for image generation and on the Speech tab for voice transcription.
The picks come from one rule that lives in the app's shared model catalog. It reads your phone's total RAM and each model's download size, then keeps only the models that run well on your phone.
An Android phone does not give one app all of its RAM, and a model needs more memory than its file size while it runs (weights, plus the cache that holds your conversation). The app's phone budget is measured from that: a file under about 36% of your RAM runs well, a file between 36% and 50% is marked Tight, and anything larger is not offered. On a 12 GB phone, that is under 4.3 GB to run well and up to 6 GB at most.
Picks come from model makers people know, such as Qwen, Gemma, Llama, Mistral and Phi. A model that a newer one replaces is never picked, and neither is a model your app's engine is too old to load. As an example from the release notes, a 12 GB phone gets Qwen 3.5 0.8B, 2B and 4B.
On Android, when you run on the CPU or the NPU, the app downloads the Q4_0 version of a model if one exists, because it runs faster there.
If you already downloaded a pick earlier, its card shows a circle icon instead. Tap it to switch to that model without downloading again.
If you download a model from the list below the picks instead, the app also makes it your active model when it finishes and shows "[model name] is ready" with Later and Chat now.
If you switch to a model that does not fit in the memory that is free right now, the app keeps your current model loaded, so you do not lose your chat.
Image and speech models have no quality score in the catalog, so these picks go by size: Best is the largest that runs well, Fast the smallest with at least 2 billion parameters, and Balanced the one in between.
When you tap a model in the list to open its details, the Sizes section shows up to three choices instead of quantization names:
Every file is still there. Tap All files under the list to see them all, and Fewer sizes to go back. Files too big for your phone are hidden, and files that only just fit carry a Tight label.
New models are added to the catalog between app releases. To get them:
The picks are worked out again with the new models included, so a better model for your phone can move into the Best slot.
What is the best local AI model for an Android phone with 8 GB of RAM? Open the Text tab in OGAM and look at the Best card: that is the highest-quality catalog model that runs well in 8 GB. On 8 GB, files under about 2.9 GB run well, so the picks are small models at 4-bit.
Which is faster on Android, Fast or Balanced? Fast is always the quicker of the two. It runs at the speed of a 4B model or faster, while Balanced is the next-best quality model and can be larger.
Does picking a model need internet? Only for the download and for checking for new models. After the download, chat, image generation and transcription with that model run on the phone with no connection.
Why does a model show Tight? Its file is between about 36% and 50% of your phone's RAM. It can load, but there is little room left for other apps and a long conversation, so a smaller size may be steadier.
Can I still choose a different model? Yes. The list below the picks has the full curated catalog, and you can search Hugging Face. The picks are a starting point, not a limit.
Why did my picks change? The picks follow the catalog. After you tap the refresh icon and new models arrive, a newer or better model that fits your phone can take a slot.
