ActiveGotchi AI — v1.0.0

A tiny multilingual companion-voice rewriting model. Given a short, pre-computed activity or sleep summary (steps, minutes, hours, streaks), it rewrites the text as a warm, playful letter from a virtual pet — in the requested language, keeping every number, name and emoji exactly as given.

It is a narrow specialist: not a chatbot, not an assistant, not a coach, and not a medical tool.

Lineage

Parent model Qwen/Qwen2.5-0.5B-Instruct (494M params, Apache-2.0)
Fine-tune LoRA (2.93M trainable params, ~0.6%), merged into the base
Training 3-stage curriculum (voice → summary rewriting → long-term reviews) + mixed rehearsal pass, on ~1M fully synthetic multilingual samples — no real user data
Quantization GGUF quants of the merged fine-tune, produced with llama.cpp llama-quantize
Released 2026-07-19

Recommended: Q4_K_M — the best size/quality balance for phones and other memory-constrained devices.

Usage

ChatML prompt format, built into the GGUF chat template — llama.cpp, llama.rn, LM Studio, Ollama etc. apply it automatically. Send ONE user message that states the persona/task and ends with the text to rewrite:

You are a small cheerful companion. Rewrite the following daily summary for
your human in your own voice. Keep every number exactly as given, keep it to
3-4 short sentences. Write your entire reply in Czech. Do not use any other
language. SUMMARY TO REWRITE: <template letter with the real numbers>

Suggested inference settings: temperature 0.6, max tokens 220, context 2048.

llama-cli -m activegotchi-ai-v1.0.0-Q4_K_M.gguf -st \
  -p "<prompt as above>" -n 220 --temp 0.6

Trained behavior

  • Never emits a number that is not present in the prompt.
  • Replies only in the language the prompt pins.
  • Short letters (3–6 sentences), no greetings, no filler.
  • Warm, non-judgmental tone; no medical advice, diagnosis or shaming.

Limitations

The model only knows what the prompt contains — it has no memory, no health knowledge, and no general-assistant abilities. Outside its rewrite task, output quality is undefined. Languages beyond en/cs/de/es/fr received less training weight. Synthetic-data style ceiling applies.
