What it is

GPT4All is the pick for users who want a fully MIT-licensed desktop AI that stays entirely offline, with no telemetry or cloud dependencies. It bridges to llama-cpp and ships a curated catalog of small-to-medium models (Llama 3.1 8B Q4_K_M is a solid fit for 4 GB VRAM). The built-in local-doc-chat works without extra services, and the Python SDK lets you script interactions programmatically. The trade-off: the UI is dated compared to LM Studio or Jan, and the catalog skews toward smaller models, so you won't find 70B-class options here. It's a mature, long-running project best suited for privacy-conscious users or those embedding local inference into their own workflows.
