Quick start

…

View on GitHub

Step 1 clone the repo

git clone https://github.com/ggml-org/llama.cpp.git
cd llama.cpp

Step 2 build

cmake -B build -DCMAKE_BUILD_TYPE=Release

cmake --build build --config Release

Step 3 run the model

the command was run from llama.cpp folder and gemma-4-E2B-it-Q4_K_M.gguf is placed in models folder.

> hello

[Start thinking]
Thinking Process:

1.  **Analyze the input:** The input is "hello".
2.  **Determine the context/intent:** This is a standard social greeting.
3.  **Formulate an appropriate response:** The response should be friendly, polite, and acknowledge the greeting. Standard responses include reciprocating the greeting and offering further interaction (e.g., asking how the user is or offering assistance).
4.  **Refine the response:** Keep it open-ended and welcoming.

*Self-Correction/Refinement:* A simple "hello" back is fine, but adding a follow-up makes the interaction more engaging.

5.  **Final Output Generation.**
[End thinking]

Hello! How can I help you today?

[ Prompt: 1.3 t/s | Generation: 1.8 t/s ]

Step 4 build with clang

sudo apt install -y clang
rm -rf build
cmake -B build -DCMAKE_BUILD_TYPE=Release \
  -DLLAMA_NATIVE=ON \
  -DLLAMA_ARM_NEON=ON

cmake --build build --config Release -j

Step 5 run the model

./build/bin/llama-cli   -m ../models/gemma-4-E2B-it-Q4_K_M.gguf   -t 4   -tb 4   -c 2048   -fa auto   --prio 3   -p "hello"

> hello

[Start thinking]
Thinking Process:

1.  **Analyze the input:** The input is "hello".
2.  **Determine the context:** This is a simple, friendly greeting.
3.  **Formulate the response goal:** The response should be equally friendly, polite, and open-ended (inviting further conversation).
4.  **Draft potential responses:**
    *   "Hello!" (Too brief, but fine.)
    *   "Hi there." (Friendly.)
    *   "Hello! How can I help you today?" (Polite, proactive.)
    *   "Hello! What can I do for you?" (Direct, service-oriented.)
5.  **Select the best response:** A standard friendly greeting followed by an invitation to continue the interaction is usually best.

6.  **Final Output Generation.**
[End thinking]

Hello! How can I help you today?

Conclusion

Raspberry Pi 5 costs around $305, so if you want to run an LLM with fewer than 10B parameters, it seems better to buy a mini PC with 16GB RAM in the $300–400 range.
