Local LLM Inference Frameworks & Tools Compared (Aug 2026)
Ollama, LM Studio, llama.cpp, vLLM, MLX, SGLang — 8 mainstream local/on-device LLM inference tools compared: positioning, platforms, model formats, license and use case. Four classes: desktop app / inference engine / Apple-native / production serving.
| Tool | Type | Platforms | Model formats | License | Best for |
|---|---|---|---|---|---|
| Ollama | Desktop app + CLI | macOS/Win/Linux; NVIDIA/AMD/Apple | GGUF (can import safetensors) | MIT | Easiest single-machine; one-line model runs |
| LM Studio | Desktop GUI | macOS(Apple Silicon)/Win/Linux | GGUF + MLX | Closed (free); SDK open | GUI users; MLX-optimized on Mac |
| llama.cpp | Inference engine/library | Cross-HW (CUDA/Metal/Vulkan/CPU) | GGUF (origin of the format) | MIT | Embedding/CPU/edge; backend of many apps |
| vLLM | Production serving | NVIDIA/AMD/Intel GPU/CPU | safetensors + many quant | Apache-2.0 | High-throughput production, GPU clusters |
| MLX-LM | Apple-native package | Apple Silicon only | MLX (HF convertible) | MIT | Apple Silicon inference & fine-tuning |
| SGLang | Production serving | NVIDIA/AMD/Intel/TPU/NPU | HF-compatible + OpenAI API | Apache-2.0 | Low-latency high-throughput, distributed |
| text-generation-webui | Desktop app / Web UI | Linux/Win/macOS; multi-backend | GGUF + safetensors | AGPL-3.0 | Power-user experiments, backend switching |
| GPT4All | Desktop app | Win/macOS/Linux; Vulkan GPU | GGUF | MIT | Private local use, modest hardware |
Method & sources
Positioning/platforms/license are from each project's official GitHub repo and docs (as of Aug 2026), retrieved 2026-08-26. **Classes**: desktop apps (Ollama, LM Studio, GPT4All, text-generation-webui) / inference-engine libraries (llama.cpp, vLLM, SGLang) / Apple-native (MLX-LM). All 8 expose an OpenAI-compatible API. License/platform are volatile — official repos govern. **Notes**: Ollama's per-GPU list is inferred from its llama.cpp backend (details medium); LM Studio's app is closed-source (free) while its SDK/CLI are open.
