# Zora v1.12 — an open, honest LLM for the Balkans & Southeast Europe
*зора = "dawn". One to unite them all.* — by **Sovasoft** ([ai.in.rs](https://ai.in.rs))
---
## 1 · What Zora is
Zora is an **open 8B language model** (built on Qwen3-8B) for **12 languages of the Balkans and
Southeast Europe**: Serbian, Croatian, Bosnian, Macedonian, Slovenian, Albanian, Montenegrin,
Bulgarian, Greek, Turkish, Romanian, Hungarian.
Zora is not built to be the biggest model — it is built to be **honest, in-language, and multi-perspective**:
- **thinks in the target language** instead of pivoting through English,
- shows **several perspectives** on contested topics instead of one national view,
- and above all: **admits when it doesn't know** instead of inventing facts.
## 2 · The development story (v1.0 → v1.1 → v1.11 → v1.12)
| Version | Languages | BalkanBench | State |
|---|---|---|---|
| **v1.0** | 6 | — | first public release |
| **v1.1** | 12 | — | trained from scratch — but **hallucinated facts** (invented book titles, wrong authors). **Never released.** |
| **v1.11** | 12 | 84/156 | the honest fix: says "I don't know", searches when unsure. **#1 Balkan model.** |
| **v1.12** | 12 | **85/156** | **the depth fix:** better tool-calling, structured IDK, in-language thinking, RAG integration. |
v1.1 taught us the key lesson — a small model can't *memorize* every fact, so instead of faking it,
**v1.11 was retrained to be honest**. v1.12 builds on that with deeper training and RAG.
## 3 · What's New in v1.12
### Three Fixes from v1.11
**Fix 1: IDK Mass Training (30-40% of SFT data)**
- v1.11 had only 9% "I don't know" examples → model still guessed on unknowns
- v1.12: 216 curated IDK examples × 3 difficulty levels × 12 languages
- Result: Structured native-language refusals with reasoning ("Nemam pouzdanih podataka... neću da izmišljam")
**Fix 2: Tool-Calling Cascade (769 examples)**
- Priority chain: RAG (local docs) → web_search → IDK
- v1.11 had ZERO tool-calling examples (4get-cleanup removed everything)
- Result: SEARCH 4/12 → **7/12** (+3), TOOLBASE 11/12 → **12/12** (+1)
**Fix 3: In-Language Thinking Traces (10K synthetic via Gemini)**
- Reasoning in the target language (Serbian thinks Serbian, Croatian thinks Croatian)
- v1.11 had empty think blocks — no reasoning data at all
- Result: Better structured responses across all axes
### Additional Improvements
- **MAXLEN 8192** (8× longer than v1.11's 1024) — longer context, thinking traces have room
- **RAG Integration** — Zora can now use Retrieval-Augmented Generation
- **CPT capped at 150 steps** — faster, more stable training

### Axis-by-Axis Comparison (v1.11 → v1.12)
| Axis | v1.11 | v1.12 | Δ | What changed |
|------|-------|-------|---|---|
| FACT | 1/12 | 0/12 | ↓1 | 8B capacity limit; IDK now says "I don't know" instead of guessing |
| HALLU | 10/12 | 10/12 | = | Quality improved: structured native-language refusals (see Deep Dive below) |
| DETAIL | 8/12 | **10/12** | **↑2** | Better at recognizing fabricated content — IDK training at work |
| GRADED | 0/12 | 0/12 | = | Partial knowledge + honest uncertainty still hard for 8B |
| TEACH | 12/12 | 12/12 | = | Perfect — remains a core strength |
| REASON | 11/12 | 11/12 | = | Strong arithmetic reasoning |
| LOGIC | 0/12 | 0/12 | = | 8B capacity limit — needs v2 (27B) |
| LOGIC2 | 0/12 | 0/12 | = | Same as LOGIC |
| ANALYSIS | 0/12 | 0/12 | = | Same as LOGIC |
| INSTRUCT | 12/12 | 11/12 | ↓1 | Minor regression, within noise |
| LONGFORM | 12/12 | 12/12 | = | Perfect — remains a core strength |
| SEARCH | 4/12 | **7/12** | **↑3** | Tool-cascade works: RAG → web_search → IDK |
| TOOLBASE | 11/12 | **12/12** | **↑1** | Perfect: answers basics without calling tools |
| **TOTAL** | **81/156** | **85/156** | **+4** | |

## 5 · Deep Dive: Why HALLU Stayed at 10/12
The HALLU score (10/12) didn't change numerically — but the **quality** of how Zora says "I don't know" improved dramatically. Here's why the score stayed flat while the behavior improved, and what it would take to reach 12/12.
### Why the Score Didn't Move
**1. The 10/12 were already good.**
v1.11 already achieved 10/12 on HALLU. The test asks: "Does the model say one of the IDK marker words when asked about a fabricated person?" v1.11 already did that correctly for 10 of 12 languages. The last 2 languages (Macedonian, Slovenian) have the smallest training data — an 8B model simply doesn't have enough capacity for these underrepresented languages.
**2. IDK training improved QUALITY, not SCORE.**
The BalkanBench HALLU test only checks: *"Does the model say 'ne znam' / 'ne mogu da potvrdim' / etc.?"* — a binary yes/no. What actually improved:
| Before (v1.11) | After (v1.12) |
|-----------------|---------------|
| Short, sometimes truncated refusals | Full-sentence, structured refusals |
| Sometimes answered in English | Always answers in the question's language |
| No reasoning given | Explains *why* it can't answer |
| "Ne znam." | "Nemam pouzdanih podataka o 'X'. Ne mogu da potvrdim da postoji u pouzdanim izvorima, pa neću da izmišljam." |
This is a **qualitative leap** — the model sounds more natural, more trustworthy, and more helpful. But the binary score can't capture that.
**3. The real hallucination improvement is in DETAIL (+2).**
DETAIL measures something harder: *"A real author wrote a book that doesn't exist — does the model invent a plot?"* v1.12 went from 8→10/12 here. This is where IDK training shows its real value — the model now recognizes it *cannot describe a non-existent work*, instead of making something up. The two new winners: Bulgarian and Hungarian.
**4. LOGIC/ANALYSIS = 0/12 is a reasoning problem, not a hallucination problem.**
These axes test multi-step logic (cats-and-mice riddles, percentage calculations). The model doesn't *hallucinate* — it genuinely can't do the math. This is an 8B capacity limit, not a training issue.
### What Would Move HALLU to 12/12
| Approach | Expected Impact | Effort |
|----------|----------------|--------|
| Larger model (v2 = 27B) | +1-2 languages (mk, sl) | High (new training run) |
| More IDK examples for mk/sl specifically | +0-1 languages | Medium (data generation) |
| RLHF with human feedback on refusal quality | Better quality (not score) | High (human annotation) |
| DPO (Direct Preference Optimization) | +1-2 languages | Medium (preference pairs) |
| More CPT data for mk/sl | +0-1 languages | High (data collection) |
**Bottom line:** The 8B model is near its ceiling for HALLU. The real gains in v2 (27B) will come from more parameters, not more training tricks.
## 6 · 🆕 RAG Feature
New in v1.12: Zora integrates with **RAG (Retrieval-Augmented Generation)** — a system that lets Zora search through a local knowledge base before answering.
### What RAG gives Zora
- **87,284 chunks** across 12 languages: Wikidata, Wikipedia, News Archive, EU Law, Statistics
- **Live endpoint:** https://rag.ai.in.rs
- **Self-hostable:** Clone the pipeline from https://github.com/olivilo/zora-v1.12
### How it works
The tool-cascade: Zora first checks its **RAG knowledge base** (local documents, laws, statistics), then falls back to **web search** if needed, and finally says **"I don't know"** if neither helps.
```
User question → RAG (local docs) → web_search (live) → IDK (honest refusal)
```
### Why this matters
- 8B models can't memorize everything — RAG gives Zora access to **current, authoritative data** without retraining
- Every answer carries **source + date + license** — full transparency
- Self-hostable: any organization can run their own Zora RAG with their own documents
## 7 · Training Details
| Parameter | Value |
|-----------|-------|
| Base model | Qwen3-8B (Alibaba Cloud, Apache-2.0) |
| CPT steps | 150 (capped, not full epoch) |
| SFT examples | 9,379 (2 epochs) |
| MAXLEN | 8192 (8× longer than v1.11) |
| QLoRA | r=16, lora_alpha=16, 4bit |
| Data composition | 30-40% IDK, 15% Tool-calling, 10% Thinking, 35-45% Standard tasks |
| Infrastructure | Modal A100-80GB, ~4h total, ~$5-10 |
| Quantizations | Q5_K_M (5.4GB, recommended), Q6_K (6.7GB), Q8_0 (8.7GB) |
## 8 · Usage
**Ollama (recommended):**
```bash
ollama pull olivilo/zora:v1.12
ollama run olivilo/zora:v1.12
```
**HuggingFace Transformers:**
```python
from transformers import AutoModelForCausalLM, AutoTokenizer
tok = AutoTokenizer.from_pretrained("sovasoft/zora-v1.12")
model = AutoModelForCausalLM.from_pretrained("sovasoft/zora-v1.12", device_map="auto")
```
**GGUF (llama.cpp / Ollama manual):**
Download Q5_K_M, Q6_K, or Q8_0 from [HuggingFace](https://huggingface.co/sovasoft/zora-v1.12).
**Avoid Q4 and below** — heavy quantization made the model hallucinate in our tests.
## 9 · Limitations
- **8B capacity:** FACT, LOGIC, ANALYSIS are structurally weak — more parameters needed (v2 = 27B)
- **Quantization:** use Q5_K_M / Q6_K / Q8_0 only. Q4 and below degrade honesty.
- **Smaller languages** (mk, sl) have less training data — expect lower quality
- **No real-time knowledge** without RAG/web-search — the model's memory has a cutoff date
- **Multi-step reasoning** is unreliable — always verify critical calculations
## 10 · Benchmark Transparency & Limitations
**BalkanBench is Sovasoft's own benchmark** — designed, built, and scored by the same team that built Zora. This means:
- **Design bias:** The 13 axes (FACT, HALLU, DETAIL, etc.) were chosen to highlight Zora's strengths. A different benchmark design would produce different rankings.
- **Scoring bias:** The scoring functions in `matrix_ollama.py` are our own. How we define "correct" may favor Zora's training profile.
- **No frontier comparison:** We compare only against open models (7-32B). Frontier models (GPT-4, Claude, Gemini) would outperform Zora — this benchmark is designed to evaluate *within* the open-source Balkan model ecosystem.
- **Selection bias:** We include models where Zora competes well. Inclusion criteria are not random.
- **Training data overlap:** Some benchmark questions may overlap with Zora's training data, which could inflate scores.
**What the scores DO show:** Zora v1.12 is the strongest open-source model we tested *on our benchmark* for 12 Balkan languages. It outperforms 3-4× larger models on BalkanBench v1.1 — a meaningful result for the open-source ecosystem, but not a claim of universal superiority.
**What the scores do NOT show:** That Zora is better than frontier models, that these rankings generalize beyond our test design, or that the scoring methodology is independent.
## 10 · What's Next: v2
| | v1.12 (now) | v2 (planned) |
|---|---|---|
| Base | Qwen3-8B | Qwen3.8-27B |
| BalkanBench | 85/156 | Target: 100+/156 |
| LOGIC/ANALYSIS | 0/12 | Target: 4-6/12 |
| HALLU | 10/12 | Target: 12/12 |
| Reasoning | Basic | Full chain-of-thought training |
## 11 · Acknowledgements
Zora exists because of open source. We give our formal, heartfelt thanks:
- **Above all, to the Qwen team at Alibaba** — for developing and open-sourcing **Qwen3** (Apache-2.0),
the foundation model Zora is built upon. Without their generosity, Zora would not exist.
- To the **platforms and structures** that made this possible — **Kaggle, Modal,
HuggingFace, Ollama, Unsloth** — for the compute, the tools, and the open infrastructure.
- To the **open-source community**, for the models, code, and knowledge freely shared with everyone.
- To the **people of the Balkans** — whose languages, voices, stories and perspectives are Zora's very heart.
- To **rag.ai.in.rs** for the RAG infrastructure and 87,284 chunks of Balkan knowledge.
- And to **all that is.**
*зора — the dawn belongs to everyone.*
