Also called lmstudio, lm studio app

LM StudioProductivity

A GUI for downloading and running local GGUF models. The process is LM Studio.exe. It is not Ollama.

What you need to know

LM Studio is a GGUF GUI. Ollama is a different runner.

LM Studio.exe is a desktop UI for local GGUF models. ollama.exe is another local runner. They do not share the same model folder. ChatGPT desktop is a cloud app.

What is it?: GUI for local GGUF models
Same as Ollama?: No. Different runner and folders
Cloud ChatGPT?: No. Weights stay on this PC

Feex says

If LM Studio.exe ate the RAM, I would unload the model in this app. I would not quit ollama.exe to close this window unless you also started Ollama. Two runners can both hold weights.

What is LM Studio?

LM Studio is a desktop GUI for local GGUF models. It is not Ollama, not ChatGPT desktop, and not Hugging Face the website.

If you have never used it

If you want a window to browse and run GGUF models, LM Studio is that GUI. Download it from lmstudio.ai. LM Studio.exe is this product. ollama.exe is a different runner with a CLI-first story. ChatGPT.exe is still a cloud client.

What is it used for?

Download GGUF models in a UI

The catalog inside LM Studio. ollama pull uses a different library and folder.

Chat against a loaded model

A desktop chat window. ChatGPT.exe still calls OpenAI.

Local server

An OpenAI-compatible local port LM Studio documents. That is not ollama serve by name.

Who is it for?

People who want a GUI instead of ollama CLI
Users hunting GGUF files with a window
Anyone who installed Ollama and wondered where the chat UI went

Current status

LM Studio (2023) is a current local model gui from LM Studio. The vendor still points Windows users at https://lmstudio.ai/.

How old is it?

LM Studio launched in 2023 alongside the local-model wave. It is the same generation as Ollama. Current Windows builds still update. A 2022 llama.cpp CLI-only setup is a different UX.

Versions

Major channels first. Exact build numbers are not all verified here.

System requirements

Values follow the publisher's public guidance. Workload still changes the real need.

Minimum

Minimum system requirements
Operating system	A current 64-bit Windows 10 or Windows 11 release, per LM Studio
RAM	The GUI is modest. The GGUF you load can want several to tens of GB

Resource profile

CPU demand: Follows what you open inside the app
RAM demand: Follows documents, tabs, or libraries

Installed processes

These executables belong to this product when it is installed.

Installed processes
LM Studio.exe	LM Studio window

Startup components

LM Studio can stay in the tray if you left the local server on. That is not Ollama's tray.

File locations

Common LM Studio locations
Typical install	C:\Users\<you>\AppData\Local\Programs\LM Studio\

File formats

GGUF

Common problems

Two local runners loaded at once

Ollama and LM Studio can both hold a model in RAM. That is two products, not a Windows memory leak by name.

Disk shock after a download

GGUF files are large. Ollama's blobs are a different cache.

Getting unstuck

Install from lmstudio.ai

LM Studio hosts the Windows build. A Studio AI pack on a freeware site is junk.

Confirm LM Studio.exe, not ollama.exe

Each has its own model directory. Deleting one cache will not clear the other.

Lower GPU offload or pick a smaller GGUF if the app crashes

That setting is inside LM Studio. ChatGPT.exe has no GGUF slider.

Alternatives

Ollama if you want a CLI and a simple service. ChatGPT or Claude if you want a cloud model. llama.cpp by itself is lower level.
