Best for	Developers and ML engineers self-hosting LLMs Teams needing on-premise or air-gapped AI for privacy Builders avoiding per-token API costs at scale	—
Pros	Free open weights you fully own and can run offline Gemma 4 uses a permissive Apache 2.0 license, simple for commercial use Multiple sizes from tiny on-device models to 31B-class quality Multimodal input (text, image, audio) and 140+ language support Broad tooling support: Ollama, LM Studio, Hugging Face, llama.cpp, Keras	Runs LLMs fully offline on your own hardware, so conversations stay private by default Simple point-and-click model downloads from Hugging Face, no command line required Genuinely open source under the permissive Apache-2.0 license Exposes an OpenAI-compatible local API server (localhost:1337) for wiring into other apps Optionally connects to cloud providers and supports MCP for agent-style tool use
Cons	Requires your own hardware and setup, no polished consumer app Largest open sizes still trail top proprietary frontier models Running bigger variants well needs a capable GPU No managed hosting, scaling, or support out of the box You are responsible for safety, moderation, and compliance	Local model quality depends heavily on your RAM and GPU; small models are far weaker than ChatGPT or Claude Decent performance effectively needs 16GB+ RAM and ideally a supported GPU Still maturing, with a fairly high open issue count and occasional rough edges Building from source on Windows is involved and requires a full compiler toolchain
