LM Studio

inference
Trial

LM Studio is a desktop application for discovering, downloading, and running large language models locally — think of it as a visual companion to Ollama, optimised for exploration rather than automation.

Buy vs Build

LM Studio is a build tool (runs on your own hardware) with a polished GUI that makes it feel more like a buy experience. Free to use; no subscription required.

Why It's in Trial

LM Studio fills a distinct niche: it makes local model experimentation accessible to engineers who don't want to use a terminal. It's also the best tool for evaluating a model before committing to deploying it with Ollama in an automated pipeline.

Key features:

  • Visual model browser: Search Hugging Face directly from the app, filter by size/capability, read model cards
  • Built-in chat: Test any model conversationally with system prompt editing, parameter controls (temperature, context size)
  • Local API server: Start an OpenAI-compatible server at localhost:1234 — point your existing code at it
  • Multi-model management: Download, manage, and switch between models with a GUI

Typical Usage Pattern

Many developers use both Ollama and LM Studio:

  1. Use LM Studio to explore and compare models visually
  2. Use Ollama for the models you've chosen in your actual development workflow and CI

Hardware Support

  • macOS: Excellent (Apple Silicon with Metal GPU acceleration)
  • Windows: Strong (NVIDIA CUDA + AMD Vulkan)
  • Linux: Beta (improving rapidly)
