CobrIX-1.0-Coder-Flash-33B-A13B-GGUF

CobrIX-1.0-Coder-Flash-MoE — GGUF

CobrIX-1.0-Coder-Flash-MoE is a custom Mixture-of-Experts (MoE) coding model distributed in ready-to-use GGUF format.

The model is built from the dense Qwen 3.5 base model empero-ai/Qwythos-9B-v2 and incorporates 5 specialized dense fine-tuned experts.

The GGUF files provided in this repository are already quantized and can be used directly with compatible inference applications such as llama.cpp, LM Studio, and other GGUF-compatible runtimes.

---

🏗️ Architecture

The model uses a custom MoE architecture based on the Qwen 3.5 model family.

Model class

Qwen35MoEForCausalLM

Model type

qwen35_moe

Context window

1,048,576 tokens

Configuration:

max_position_embeddings = 1048576

Expert routing

The model contains:

5 total experts
2 experts activated per token

This uses Top-2 routing, where the router selects two experts from the five available experts for each token.

Shared expert

The architecture also contains one shared expert that remains active for every token.

num_shared_experts = 1

The shared expert is based on the base model's MLP and uses a sigmoid gating mechanism.

📦 GGUF Quantizations

Q3_K_M

CobrIX-1.0-Coder-Flash-33B-A13B-Q3_K_M.gguf

The smallest provided quantization.

Recommended when memory usage is the primary concern.

Advantages:

• Lowest memory requirements
• Good performance on lower-end hardware
• Suitable for systems with limited VRAM/RAM

Trade-off:

• Lower quality than Q4/Q5/Q8

---

Q4_K_M ⭐ Recommended

CobrIX-1.0-Coder-Flash-33B-A13B-Q4_K_M.gguf

The recommended general-purpose quantization.

Advantages:

• Excellent quality/size balance
• Good inference speed
• Suitable for a wide range of GPUs and CPUs
• Recommended for everyday coding

---

Q5_K_M

CobrIX-1.0-Coder-Flash-33B-A13B-Q5_K_M.gguf

Provides higher precision than Q4_K_M.

Recommended when additional memory is available and maintaining higher model quality is more important than minimizing model size.

---

Q8_0

CobrIX-1.0-Coder-Flash-33B-A13B-Q8_0.gguf

The highest-precision GGUF quantization provided in this repository.

Recommended for systems with sufficient memory where maximum GGUF quality is preferred.

---

🦙 Using with llama.cpp

The GGUF files can be loaded directly using llama.cpp.

Example using llama-cli:

llama-cli \
  -m CobrIX-1.0-Coder-Flash-33B-A13B-Q4_K_M.gguf \
  -p "Write a Python script to set up an async web server using FastAPI." \
  -n 512 \
  -ngl 99 \
  -c 4096

Important

The -c 4096 value in this example is only an example context size.

The model supports a native context window of up to:

1,048,576 tokens

However, using the maximum context requires significantly more memory and depends on the inference backend and hardware.

---

🐍 Python — llama-cpp-python

Install the Python binding:

pip install llama-cpp-python

Then:

from llama_cpp import Llama

llm = Llama(
    model_path="./CobrIX-1.0-Coder-Flash-33B-A13B-Q4_K_M.gguf",
    n_gpu_layers=-1,
    n_ctx=4096,
    verbose=True
)

output = llm(
    "Hello, how can I optimize a React re-render loop?",
    max_tokens=128,
    stop=["<|endoftext|>"],
    echo=False
)

print(output["choices"][0]["text"])

---

🖥️ LM Studio

The GGUF files can also be loaded into LM Studio.

Steps

1. Download the desired .gguf file from this repository.
2. Open LM Studio.
3. Import or place the GGUF file in your local model directory.
4. Select the model.
5. Configure the desired GPU offloading and context size.
6. Start the model.

For most users, start with:

Q4_K_M

and increase the quantization if additional memory is available.

---

🦙 Ollama

The GGUF weights can also be used with compatible Ollama workflows.

A basic Modelfile can be created as follows:

FROM ./CobrIX-1.0-Coder-Flash-33B-A13B-Q4_K_M.gguf

Then create the model:

ollama create cobrix-1.0-coder-flash -f Modelfile

Run it:

ollama run cobrix-1.0-coder-flash
