You may need AI to draft a paragraph, create an illustration and read the result aloud. You do not need to do all three at the same instant.
OGAD (Off Grid AI Desktop) brings those local model types into one app. On a Mac, you can move through the jobs in sequence and unload a model when you need its memory for the next task. This gives you a practical way to try more than text chat without treating every model as a permanent background process.
This guide uses the Mac route for chat, image generation and spoken output. The verified Windows stable release does not package the same local speech-output runtime, so do not assume that every step applies to Windows.
Turn one idea into three useful outputs
Consider a short presentation. Use a text model to draft the opening, an image model to create a background illustration, and a speech model to hear whether the opening sounds natural.
Each model has a separate job. You can finish and save one result before starting the next. The saved paragraph or image remains useful when its generating model is no longer in memory.
Start with small text and image model choices suited to the Mac's RAM. In Models, check the size and memory guidance. A model that cannot fit by itself will not become viable just because you run the tasks in sequence.
Set up a small first project
- Download a local text model that fits your Mac.
- In Chat, ask for a short presentation opening. Review and keep the text.
- In Models, download and select a local image model that fits the machine. In Chat, open the + composer menu, choose Generate image, and describe one simple illustration.
- Follow the Mac speech setup guide: choose a local voice in Settings → Voice, wait until it is ready, then play a completed reply. Start with one short paragraph.
- Keep the results you want before expanding the task.
Local models need an initial download. After the required files are present, these local requests can run without internet. Chat, image generation and the supported Mac speech runtime are core capabilities; Pro capture is not required for this workflow.
Free memory without deleting the download
The model picker includes Unload for a loaded model type. It releases that model from memory. It does not mean you must download its files again; the model can load on the next use.
Use this when a model is no longer needed and you want to give the next task more room. Expect a load delay when you return to it. Model switching is a resource trade-off, not a guarantee that every request starts instantly.
For long text chats, a smaller Context window can also reduce memory pressure. For images, begin with a modest supported image size and one output. Keep other heavy applications closed during the first trial.
Know which limit you have reached
If the model will not load even with other work closed, use a smaller compatible model. If it loads but the task takes too long, simplify the request and compare another model on the same task. Do not confuse a successful download with a model that fits comfortably in working RAM.
The controls described here are available in OGAD 0.0.51.
