Gargantua Pi (270M)

Gargantua Pi is the tiniest model of the openTARS assistant. It is built for small boards and low-power machines: Raspberry Pi, Orange Pi and any computer without a graphics card. At about 300 MB it loads in a moment and answers on the CPU.

It does four things well: run a terminal command, search the web, remember a fact, and forget one. It answers in Portuguese and English and politely says so when you ask for something it cannot do, such as looking at the screen.

Base: FunctionGemma 270M, fine-tuned by the openTARS project on its own tool-use data (4 tools: execute_terminal, search_web, remember, forget).
File: gargantua-1.2-pi-functiongemma-270m-Q8_0.gguf (0.3 GB).
Runs with: llama.cpp and Ollama (the functiongemma renderer and parser are built in).
License: Gemma Terms of Use, inherited from the base model. Anyone who redistributes it must pass those terms on.

Use

With Ollama, create the model from the downloaded file:

printf 'FROM ./gargantua-1.2-pi-functiongemma-270m-Q8_0.gguf\nRENDERER functiongemma\nPARSER functiongemma\nPARAMETER temperature 0.1\n' > Modelfile
ollama create gargantua-pi -f Modelfile
ollama run gargantua-pi "how much free memory is there?"

Pass the four tools in the request so it can call them. The openTARS app does this for you.

Measured result

On our own 39-request check of the first move (pick the right tool, or none) it gets 31 of 39 right. This is our own test, not a public benchmark.
