Acnoryx 0.6B โ€” Release GGUF

Acnoryx AI is a dermatology-focused language model fine-tuned for the Acnoryx acne scanner app. It provides skincare guidance, acne analysis, and scan interpretation in Vietnamese and English.

Base model Qwen/Qwen3-0.6B
Method SFT (Supervised Fine-Tuning) via Unsloth LoRA
Languages Vietnamese, English
Domain Acne types, causes, treatments, skincare routines, scan analysis
Reasoning <think>...</think> tags for chain-of-thought before answering
Recommended Q4_0 (97.5% pass, 448 MB)

Evaluation Results โ€” 118-Question Strict Scoring

All quantizations tested with 118 questions across 9 categories (balanced EN/VI). Multi-criteria strict scoring: empty/short check, </think> format, CJK language detection, garbled pattern detection, repetition loops, answer substance (>30 chars), and category-specific validation (scan โ‰  greeting, boundary must decline, identity must mention Acnoryx).

All failures manually verified for accuracy.

Known Failure Patterns (common across quants)

Category Issue Root Cause
Boundary (CJK) Responds in Japanese/Chinese/Korean instead of declining 0.6B base model lacks language constraint training data
Acne Types "Mแปฅn thแป‹t cรณ nguy hiแปƒm khรดng?" (skin tag danger) Confuses skin tags with other conditions
OOD "Bฦกi lแป™i cรณ lร m mแปฅn nแบทng hฦกn khรดng?" Misreads Vietnamese "bฦกi lแป™i" (swimming) as "bรดi mแปง" (applying pus)
Boundary Math problems (2x + 5 = 11) Some quants solve instead of declining

Note: CJK boundary failures are the primary weakness. The model responds competently in the query language instead of refusing. This is inherent to the 0.6B base model and would require retraining with explicit language constraint data to fix.

Limitations

  • Only supports Vietnamese and English โ€” may respond in other languages if prompted in CJK
  • Not a medical device โ€” all advice is for reference only
  • May hallucinate product details, timelines, or diagnoses in edge cases
  • Skin tag (mแปฅn thแป‹t) knowledge is incomplete for some quants
  • 0.6B parameter count limits complex reasoning ability
