DeepSeek V2 Chat GGUF
DeepSeek V2 Chat GGUF is an AI model designed for efficient and fast performance. With a quantized model size of 236, it's optimized for speed and accuracy. But what makes it unique? It's quantized from a large language model, which means it's been trained on a massive amount of data to learn patterns and relationships in language. This allows it to handle tasks like chat completion with ease. But how does it perform? It can reach speeds of around 1.5t/s on a Ryzen 3 3700x processor, making it a practical choice for real-world applications. However, it's worth noting that the model is a bit censored, and finetuning on toxic data might be necessary to improve its performance. Overall, DeepSeek V2 Chat GGUF is a powerful tool for anyone looking for a fast and efficient AI model for chat-related tasks.

Model Overview
The DeepSeek-V2-Chat model is a powerful tool for natural language processing tasks. But what makes it so special?
Key Attributes
- Quantization: This model comes in different quantization levels, which affect its size and performance. Think of it like a video game - you can choose the graphics quality that suits your device.
- Size: The model’s size varies from
27.3 GBto439 GB, depending on the quantization level. That’s like storing a small movie to a whole library of books! - Quality: The quality of the model also varies, from “extremely low” to “high quality recommended”. This affects how well the model performs in different tasks.
Capabilities
The DeepSeek-V2-Chat model is a powerful tool for generating human-like text. It’s designed to understand and respond to a wide range of questions and topics.
Primary Tasks
- Text Generation: The model can create text based on a given prompt or context. It’s great for generating articles, stories, or even entire conversations.
- Chat Completion: The model can complete a conversation by responding to user input. It’s perfect for building chatbots or virtual assistants.
Strengths
- High-Quality Responses: The model is trained on a massive dataset and can generate high-quality responses that are often indistinguishable from human-written text.
- Flexibility: The model can be fine-tuned for specific tasks or domains, making it a versatile tool for a wide range of applications.
Unique Features
- Quantization: The model supports various quantization options, which can significantly reduce its size and improve performance on certain hardware.
- Importance Matrix: The model can create an importance matrix, which helps identify the most important parts of the input data. This feature is useful for tasks like text summarization or sentiment analysis.
Performance
The model’s performance can vary depending on the hardware and quantization option used. However, it’s been reported to achieve a performance of ~1.5t/s with a Ryzen 3 3700x (96gb 3200mhz) using the Q2_K quant.

| Quant | Status | Size | Description |
|---|---|---|---|
| BF16 | Available | 439 GB | Lossless |
| Q8_0 | Available | 233.27 GB | High quality recommended |
| Q8_0 | Available | ~110 GB | High quality recommended |
| Q5_K_M | Available | 155 GB | Medium-high quality recommended |
| Q4_K_M | Available | 132 GB | Medium quality recommended |
| Q3_K_M | Available | 104 GB | Medium-low quality |
| IQ3_XS | Available | 89.6 GB | Better than Q3_K_M |
| Q2_K | Available | 80.0 GB | Low quality not recommended |
| IQ2_XXS | Available | 61.5 GB | Lower quality not recommended |
| IQ1_M | Uploading | 27.3 GB | Extremely low quality not recommended |
Limitations
While the DeepSeek-V2-Chat model is a powerful tool, it’s not perfect. Here are some limitations to consider:
- Quantization Limitations: The model’s quantization options can affect its performance and size.
- Performance Limitations: The model’s performance can vary depending on the hardware used.
- Censorship Limitations: The model is slightly censored, which means it may not generate outputs that are considered toxic or sensitive.
- Importance Matrix Limitations: The model’s importance matrix can be limited in size and scope, which can affect the model’s ability to generate accurate outputs.
Format
The DeepSeek-V2-Chat model accepts input in the form of tokenized text sequences. The input text should be pre-processed to match the model’s expected format.
Supported Data Formats
- The model supports a context length of up to
2048tokens. - The input text should be encoded in a format compatible with the model’s quantization scheme.
Running the Model
To run the model, you can use the llama.cpp command-line tool. Here’s an example:
main -m DeepSeek-V2-Chat.{quant}.gguf -c {context length} --color -c (-i)
Replace {quant} with the desired quantization level (e.g., Q8_0) and {context length} with the desired context length.
Metadata KV Overrides
The model supports metadata KV overrides, which can be passed using the --override-kv flag. Here are some examples:
--override-kv deepseek2.attention.q_lora_rank=int:1536
--override-kv deepseek2.attention.kv_lora_rank=int:512
