Try it in your browser: the new tinybrainbot-350mV3-math-Q80.gguf (371 MB) runs locally on your device with WebGPU, and nothing you type is sent anywhere. A 348M-parameter decoder-only model fine-tuned to do column arithmetic with a written-out scratchpad. Successor to the TinyBrainBot 320M V2 Math. TL;DR: 99.4% average across the nine GPT-3 arithmetic sub-tasks, beating the 320M V2 Math (91.5%). Adds cleanly to 14 digits, does 3-digit multipliers (98.0%), and handles negative results (85% overall, but only 58% at 5 digits - see below). It is a calculator with a scratchpad, not a word-problem solver — see the honest limits below. Use applychattemplate rather than hand-building the prompt…
