# LM Studio Application: LM Studio Also called lmstudio, lm studio app LM Studio, Productivity 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. LM Studio ## System requirements Values follow the publisher's public guidance. Workload still changes the real need. ### Minimum | 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. | 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 | Typical install | C:\Users\\\\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. ## Official help and downloads Start with the vendor.
