LM Studio

LM Studio is a desktop application for downloading and running open-weights language models locally. It uses the LM Studio runtime with llama.cpp and MLX under the hood, and supports simple chat as well as agentic tasks with locally run models.

Its current focus is Bionic, an agent that creates and edits documents, slides and PDFs, writes code, runs automations and can control the computer. Documents are saved automatically after each change. The app also provides real-time voice transcription that the vendor says is processed locally on the device, with multi-language support.

The Free plan covers running local models, the Bionic agent, offline voice transcription, LM Link for up to 5 devices and limited web search. Paid plans (Bionic+ and Pro) add US-hosted open-source models such as Kimi K3, GLM 5.3 and DeepSeek V4 Flash, plus web search and page extraction; the vendor states its cloud services use Zero Data Retention. Local performance depends on the user's hardware and the chosen model. The software itself is closed-source; specific prices were not given in the provided material.
