This repository is publicly accessible, but you have to accept the conditions to access its files and content.
This DoRA adapter encodes the personal writing style of Yuka Kust, derived from her own private Telegram messages used as training data with her explicit consent. Please confirm: (1) You will use this model for research purposes only — comparing personalization techniques, studying DoRA behavior, replicating findings. (2) You will not deploy this to generate content presenting itself as Yuka Kust to third parties, impersonate her in any communication, or attempt to extract training data. (3) You will cite this work in any publication.

yuka-dora-v1 — Personal DoRA adapter on Qwen3-8B
🔬 Research artifact. First server-trained DoRA adapter for personal-AI research at Aiconic. Validates that DoRA captures user voice with effectively zero catastrophic forgetting.
Status: Sprint S65 (2026-05-12) — first successful server-scale DoRA for personal voice. Adapter size: 63 MB (vs ~16 GB for full fine-tune — 250× compression) Result: 100% blind A/B win vs Qwen3-8B stock on hold-out prompts.
TL;DR results
We trained a DoRA adapter on Qwen3-8B using 6128 anonymized Yuka↔friend chat pairs from a Telegram export (consent given). On 30 hold-out prompts evaluated via blind 3-way A/B (5 voters, 120+ votes):
| Comparison | Result |
|---|---|
| DoRA vs Qwen3-8B stock | DoRA wins 100% of head-to-head |
| DoRA vs real Yuka messages | Real wins 71% / DoRA wins 29% (1× DoRA actually beat real Yuka) |
| Catastrophic forgetting | 0 percentage points lost on 50 baseline tasks |
The model successfully captures the user's writing voice while preserving full generality on unrelated tasks. This is the substantive technical claim of this artifact.
📖 Full write-up
→ We trained a personal voice DoRA for $1.50 — and it beat stock Qwen3-8B 100% in blind A/B
In-depth post covering methodology, blind A/B protocol, the one prompt where DoRA beat the real human, what didn't work (Qwen3 reasoning mode, transformers version dance, Cerebras adapter loading), and what it means for the future of personal AI.

Critical inference note
Qwen3 is a reasoning model with <think> mode. For chat serving, you must set enable_thinking=False in tokenizer config — otherwise the adapter outputs reasoning traces that bypass voice adaptation.
from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel
import torch
base = "Qwen/Qwen3-8B"
adapter = "aiconiccompany/yuka-dora-v1"
tokenizer = AutoTokenizer.from_pretrained(base)
model = AutoModelForCausalLM.from_pretrained(base, torch_dtype=torch.bfloat16, device_map="auto")
model = PeftModel.from_pretrained(model, adapter)
messages = [{"role": "user", "content": "what are you doing tonight?"}]
inputs = tokenizer.apply_chat_template(
messages,
add_generation_prompt=True,
enable_thinking=False, # ← CRITICAL
return_tensors="pt",
).to(model.device)
out = model.generate(inputs, max_new_tokens=200, temperature=0.8, do_sample=True)
print(tokenizer.decode(out[0][inputs.shape[1]:], skip_special_tokens=True))
Ethics & gating
This adapter encodes the personal voice of a real person (the model's author, Yuka Kust). She gave consent to publish it as a research artifact.
Gating (extra_gated_* above) requires users to acknowledge:
- Research-only use
- No deployment as "Yuka chatbot" to third parties
- No impersonation in communications
- Cite this work if used in publication

Cerebras 235B note
We attempted to serve this adapter on Cerebras 235B inference (production LLM at Aiconic). Cerebras prod does not load LoRA/DoRA adapters — adapter inference works only via local transformers + PEFT pipeline. This is a research artifact, not a production-served voice.
