Sungur-3x9B-T1

Name: Sungur-3x9B-Gemma
Availability: InStock

Sungur-3x9B-T1 is a Domain-Specialized Sparse Mixture of Experts (MoE) model designed for high-performance Turkish text generation. It is built upon the robust google/gemma-2-9b-it as its base foundation.

This model was constructed using Gemma-2-MoE, a custom library I developed to build Gemma 2 based MoE models. Unlike traditional merges that rely purely on random router initialization, this model uses Semantic Router Initialization followed by a targeted fine-tuning stage.

It combines the strengths of three 9B models—including my own Sungur-9B—into a single efficient inference engine.

Note on Benchmark Results: The evaluation results show a performance level that is generally consistent with the strongest individual expert models, rather than a significant leap forward often seen in fully trained MoE models. This is primarily because the model's core expert weights were frozen during the brief fine-tuning stage; only the router was trained to route tokens to the correct specialist. For future iterations, a full fine-tuning pass across all expert weights and the router is anticipated. This will allow the distinct expert models to learn to cooperate and complement each other, leading to a substantial gain in overall benchmark performance and cross-domain synergy.

Expert Composition (Top-2 Routing)

The model dynamically routes each token to the top 2 experts, combining logic, academic knowledge, and creative nuance.

Expert Slot	Role	Source Model	Specialization
Expert 0	The Reasoner	`ytu-ce-cosmos/Turkish-Gemma-9b-T1`	Logic, Math, Python/JS Coding, Algorithms, Chain-of-Thought.
Expert 1	The Scholar	`ytu-ce-cosmos/Turkish-Gemma-9b-v0.1`	History, Biology, Physics, Academic Knowledge, Encyclopedic Facts.
Expert 2	The Creative	`suayptalha/Sungur-9B`	Chat, Roleplay, Storytelling, Poetry, Daily Conversation.

Build & Training Methodology

1. Semantic Router Initialization

Using my Gemma-2-MoE builder, the initial router weights were calculated using Concept Algebra on the embedding space. $$\text{Expert Vector} = \text{Mean}(\text{Positive Prompts}) - 0.5 \times \text{Mean}(\text{Negative Prompts})$$

2. Router Fine-Tuning

After construction, the base model and expert weights were frozen. Only the router (gating) network was fine-tuned for 2 epochs using a synthetic dataset of 1,500 samples. This dataset contained prompt-expert pairs (e.g., a Python question paired with the Reasoner expert) to sharpen the router's decision-making and ensure prompts are sent to the correct domain specialist.

Build Configuration

This model was built using the following YAML configuration, which defines the experts and semantic routing logic:
