make-localllm-easier — run the best local LLM your GPU can handle, in one command

localllm picks, downloads and runs the most accurate local AI model for your PC and your language, chosen from real benchmark measurements, with llama.cpp tuned for AMD, NVIDIA, Intel and Apple GPUs.

pip install make-localllm-easier
localllm

That's it. localllm checks your GPU and RAM, picks the most accurate model we have measured for your language that fits your card, downloads llama.cpp and the model, starts it with settings profiled op by op, and opens the chat page. You also get an OpenAI-compatible API at http://127.0.0.1:8080/v1 for any app that speaks it. Offline, private, free.

FAQ

Which local LLM should I run on my GPU? Run localllm doctor. It lists which model sizes fit your card (4B up to 120B MoE), at which quantization, how fast they should run, and the most accurate measured model for your language.

Can a 16 GB GPU run a 27B model? Yes. Qwen3.8-27B at ~3.5 bits (12.2 GB) runs at ~50 tok/s on an RX 9070 XT and keeps 81.8% on English Global-MMLU-Lite. gemma-4-26B-A4B (13.3 GB) runs at ~69 tok/s with similar accuracy.

Is a 2-bit quantized model good enough? Usually not for non-English use: 2-bit costs 8-13 accuracy points, and Hindi, Arabic and Thai lose the most (13 points).

Why is llama.cpp slow on my AMD (or Intel) GPU on Windows? If Resizable BAR is off, llama.cpp's Vulkan backend puts buffers in a 256 MB host-visible heap backed by system RAM and decode drops up to 1.7x. localllm sets GGML_VK_DISABLE_HOST_VISIBLE_VIDMEM=1 for you (llama.cpp#27097).

Does it work offline? After the first download, yes. Nothing leaves your PC.

Which languages are measured? 23 languages on Global-MMLU-Lite, 44 countries' own exams on INCLUDE, plus Thai (ThaiExam). localllm eval --langs ... measures any of them on your hardware.

Accuracy (%) on multiple-choice exams, zero-shot. global = Global-MMLU-Lite: the same 400 questions translated, so languages compare like for like. regional = INCLUDE: real exams written in each country (ThaiExam for Thai).

Cells are global / regional. Margins are about ±4 (global) and ±5 (regional) points at 95%, so localllm treats gaps under 2 points as a tie and picks the faster model.

Findings worth knowing

1. 2-bit costs 8-13 points, and lower-resource languages pay the most. Hindi, Arabic and Thai lose 13; English, Chinese and Spanish about 8-9. A 177B MoE squeezed to 1.6 bits scored below a 27B at 3 bits.
2. Calibrating the quantization on your language doesn't help at ~3.5 bits. A Thai-text importance matrix scored the same as the stock one in Thai, English and Chinese (64.8 vs 64.6 Thai). At this level the number of bits matters, the calibration text doesn't.
3. AMD/Intel cards without Resizable BAR lose up to 1.7x decode speed in llama.cpp's Vulkan backend. Hybrid DeltaNet models (Qwen3.5/3.8) suffer most: they rewrite a 3 MB state per layer per token.
4. Qwen3.8 GGUFs ship a multi-token-prediction head. Drafting 2 tokens with it adds ~40% decode speed for free; drafting 3 is slower.
5. The first run of a new llama.cpp build is slow while the GPU driver compiles its shaders once (~15 s).

How the benchmark works

localllm eval asks each question with thinking off and reads the log-probability of every answer letter from the first generated token, then takes the most likely one. It's prompt processing only, so a language takes a few minutes, and the result is deterministic. Data is downloaded at eval time from the original Apache-2.0 datasets (Global-MMLU-Lite, INCLUDE, ThaiExam) and never redistributed. It measures knowledge and reasoning in multiple choice, not writing quality.

The catalog only grows with measurements. Run localllm eval --langs en,<yours> on your GPU and open a PR with ~/.localllm/results.json and your GPU name. Other languages' local exams are very welcome. See ROADMAP.md for what's next: using less system RAM (0.2), working alongside cloud provider APIs (0.3), and a speed-only release (0.4).
