Version: 0.1 — Why So Early?

This model is at version 0.1 because its current evaluation results reflect meaningful room for improvement.

Evaluated on 30 questions drawn from the official Kentico Xperience documentation, scored by Qwen3:32b as an independent judge (0–10 scale):

Metric	Result
Average score	5.7 / 10
Score ≥ 7 rate	40% (12 / 30)
Average response time	1.4s

The 0.1 versioning is intentional and honest — the model is functional and useful for many queries, but there are known dataset quality issues that will be addressed in future iterations.

Known Issues & Planned Improvements

The following problems were identified through systematic evaluation and are documented here for full transparency:

Format Issues

Question echo as heading — Most responses start with ## {question text} or ### {question text}. This is caused by training examples where assistant answers included the question as a heading.
Fix: strip heading prefixes from all assistant turns in the training data.
One-sentence truncated answers — Some responses end abruptly after a single sentence (e.g., "Xperience gives you complete control over your content.").
Fix: enforce minimum response depth in training examples.

Factual Errors

Topic	Error
Headless draft vs. published	Model incorrectly states that draft items are accessible via the headless API — only Published items are
Content sync — image variants	Model gave an irrelevant e-commerce paragraph instead of answering the actual question
Automation license tier	Incomplete or incorrect license tier information
Email channel license tier	Wrong license threshold stated

Terminology Inconsistencies

Model uses "Asset tiles" instead of the correct term "content item assets"
Inconsistent usage of "Content Hub" vs. older naming conventions from previous Kentico versions

Weak Topic Coverage

The following topics scored lowest and need additional training examples:

Topic	Issue
Pages vs. Content items	Core conceptual difference covered too superficially in training data
Content sync — image variants	Too few specific examples in the dataset
Headless draft / publish lifecycle	Frequently misunderstood; needs correct, emphatic examples
License tier comparisons (Automation, Email)	License feature tables not well-represented in training data
Smart Folder creation (step-by-step)	Procedural steps are missing from examples

Capabilities

Chat: Answer questions about Kentico Xperience development, content management, digital marketing, e-commerce, and best practices
Multilingual: English (primary) + inherited multilingual capabilities from Mistral-Nemo base

Training Data

Fine-tuned on the official Kentico Xperience documentation:

docs.kentico.com — Documentation, guides, and training materials
api-reference.kentico.com — API reference

The full training dataset is available at omerkaragulmez/XbyK-0.1-dataset.

Usage

python

from transformers import pipeline

pipe = pipeline("text-generation", model="omerkaragulmez/XbyK-0.1", torch_dtype="bfloat16", device_map="auto")

messages = [
    {"role": "user", "content": "How do I create a content type in Kentico Xperience?"}
]

response = pipe(messages, max_new_tokens=512, temperature=0.3)
print(response[0]["generated_text"][-1]["content"])

With Ollama (recommended)

The quantized GGUF (gguf/XbyK-0.1-Q4_K_M.gguf) is available in this repo and can be used directly with Ollama:

bash

ollama create xbyk-0.1 -f gguf/Modelfile
ollama run xbyk-0.1 "How do I use the Delivery API?"
