Model Details

Table with columns: Field, Value
Field	Value
Developed by	Giorgi Duchidze (@Duchidzeg)
Model type	LoRA adapter over a Phi-3.5-mini-instruct causal LM
Language	Georgian (ქართული)
License	Apache 2.0
Base model	`tbilisi-ai-lab/kona2-small-3.8B`
Training data	`Duchidzeg/ilia-persona-sharegpt`

Uses

Direct Use

Georgian-language conversational AI in Ilia Chavchavadze's authorial voice. Suited for:

Educational demos about Ilia's ideas (language, homeland, education, national identity)
Cultural and literary interactive experiences
Georgian-language NLP experimentation on low-resource persona fine-tuning

Downstream Use

Starting point for further Georgian persona fine-tunes
Reference implementation for QLoRA on ~4 B models with 8 GB VRAM
Chat interfaces (Gradio, Streamlit, Ollama after merging the adapter into the base)

Out-of-Scope Use

Factual reference on Ilia's biography, works, or 19th-century Georgian history. Outputs may include stylized quotes that are not verbatim from his writings. Do not cite this model as a source.
Contemporary political or modern-day commentary. The persona is designed to stay in-period and deflect modern topics.
Non-Georgian tasks. The base model is Georgian-specialized.

Bias, Risks, and Limitations

Persona bias. The model is deliberately trained to hold Ilia Chavchavadze's 19th-century worldview — strong national-identity emphasis, religious framing, formal address (ბატონო, ძვირფასო). Outputs are not neutral commentary.
Stylized quotes. Some responses include verse-like or aphorism-like passages that are stylistically Ilia but not verbatim from his works. Always cross-reference with primary sources for citation.
Parametric memory only. No retrieval or grounding — the model relies entirely on what it learned during fine-tuning.
Generation settings matter. Use repetition_penalty ≈ 1.15 and temperature ∈ [0.3, 0.6] to avoid the base model's tendency to loop on longer outputs.

Example Interaction

User: ვინ ხართ? Ilia: მე ვარ ილია ჭავჭავაძე, თერგდალეულთა თაობის მოღვაწე. ჩემი კალამი მამულს ეძღვნება.

User: რას ფიქრობთ ქართული ენის მდგომარეობაზე? Ilia: ენა ერის სულის სარკეა; როდესაც ენა იტანჯება, ერიც იტანჯება. ჩვენი ენა დიდი ხანია იბრძვის, მაგრამ მისი გადარჩენა მხოლოდ განათლებული თაობების ხელით თუ იქნება შესაძლებელი.

User: რას ნიშნავს მამულის სიყვარული? Ilia: მამულის სიყვარული ის არის, როცა ადამიანი თავის სიცოცხლეზე მეტად სამშობლოს კეთილდღეობას უფრთხის. ვინც ამას ვერ ხედავს, მას ერიც არ უყვარს და არც თავისი ღირსება გააჩნია.
