+# Model Card for geoffmunn/Qwen3Guard-StarTrek-Classification-4B
 
+This is a fine-tuned version of **Qwen3-4B** using LoRA (Low-Rank Adaptation) to classify whether user-provided text is related to *Star Trek* or not. The model acts as a domain-specific content classifier, returning one of two labels: `"related"` or `"not_related"`. It was developed as part of the Qwen3Guard demonstration project to showcase how large language models can be adapted for custom classification tasks.

+This model is a binary sequence classifier fine-tuned on a synthetic dataset of Star Trek-related questions and general non-Star-Trek text. Built atop the Qwen3-4B foundation model, it uses parameter-efficient fine-tuning via LoRA to adapt the model for topic detection in conversational or input text. It is designed for use in moderation systems where filtering based on pop culture topics like *Star Trek* is desired.

 ## Uses
 
-<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. -->
-
 ### Direct Use
 
-<!-- This section is for the model use without fine-tuning or plugging into a larger ecosystem/app. -->
-
-[More Information Needed]
+The model can directly classify whether a given piece of text is related to *Star Trek*. Example applications include:
+- Filtering fan forum posts
+- Moderating trivia chatbots
+- Enhancing themed AI assistants
+- Educational tools focused on science fiction media
 
-### Downstream Use [optional]
+Input: A string of text  
+Output: One of two labels — `"related"` or `"not_related"`
 
-<!-- This section is for the model use when fine-tuned for a task, or when plugged into a larger ecosystem/app -->
+### Downstream Use
 
-[More Information Needed]
+This model can be integrated into larger systems such as:
+- Themed conversational agents (e.g., a *Star Trek*-focused chatbot)
+- Content recommendation engines that route queries based on topic relevance
+- Fine-tuning starter for other sci-fi franchises (e.g., *Star Wars*, *Doctor Who*) using similar methodology
 
 ### Out-of-Scope Use
 
-<!-- This section addresses misuse, malicious use, and uses that the model will not work well for. -->
+This model should **not** be used for:
+- General content moderation (toxicity, hate speech, etc.)
+- Medical, legal, or safety-critical decision-making
+- Multilingual classification (trained only on English)
+- Detecting nuanced sentiment or emotion
+- Classifying topics outside entertainment/pop culture without retraining
 
-[More Information Needed]
+It may produce inaccurate classifications when presented with ambiguous references, parody content, or highly technical scientific discussions unrelated to *Star Trek* lore.
 
 ## Bias, Risks, and Limitations
 
-<!-- This section is meant to convey both technical and sociotechnical limitations. -->
+The training data consists entirely of synthetically generated questions about *Star Trek*, which introduces several limitations:
+- Potential overfitting to question formats rather than natural language statements
+- Limited coverage of obscure characters, episodes, or expanded universe material
+- No representation of non-English *Star Trek* content
+- Biases toward canonical series (TOS, TNG, DS9, etc.) over newer entries
 
-[More Information Needed]
+Additionally, because the dataset was auto-generated using prompts, there may be inconsistencies in labeling or artificial phrasing patterns.
 
 ### Recommendations
 
-<!-- This section is meant to convey recommendations with respect to the bias, risk, and technical limitations. -->
-
-Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. More information needed for further recommendations.
+Users should validate performance on real-world data before deployment. For production use, consider augmenting the dataset with human-labeled examples and testing across diverse inputs. Always pair this model with broader safeguards if used in public-facing applications.
