The IMatrix is a technique used to improve the model’s performance, but it’s not applied everywhere. According to the investigation, only lower quantizations benefit from the IMatrix input. This means that the model may not always be able to take full advantage of the IMatrix.
Split GGUF Files
The model’s files are sometimes split into multiple parts, which can make it difficult to download and use. While there are tools available to merge these files, such as gguf-split, it can still be a hassle.
Format
This model uses a transformer architecture and accepts input in the form of tokenized text sequences.
Architecture
The model is based on the DeepSeek-V2.5 architecture, which has been quantized using the IMatrix method. This means that the model’s weights have been reduced to a lower precision, making it more efficient and faster to use.
Supported Data Formats
The model supports the following data formats:
- Tokenized text sequences
- Quantized weights (using the IMatrix method)
Input Requirements
To use the model, you’ll need to preprocess your input text into tokenized sequences. You can do this using a library like transformers.
Here’s an example of how to preprocess input text:
import transformers
# Load the tokenizer
tokenizer = transformers.AutoTokenizer.from_pretrained("DeepSeek-V2.5-IMat-GGUF")
# Preprocess the input text
input_text = "This is an example sentence."
inputs = tokenizer.encode_plus(
input_text,
add_special_tokens=True,
max_length=512,
return_attention_mask=True,
return_tensors="pt"
)
Output Requirements
The model outputs a sequence of tokens, which can be converted back into text using the transformers library.
Here’s an example of how to convert the output tokens back into text:
# Get the output tokens
output_tokens = model(inputs["input_ids"], attention_mask=inputs["attention_mask"])
# Convert the output tokens back into text
output_text = tokenizer.decode(output_tokens[0], skip_special_tokens=True)
Special Requirements
The model has some special requirements:
- The input sequence length should be less than or equal to 512 tokens.
- The model requires a specific format for the input sequence, which includes special tokens like
<|begin▁of▁sentence|>and<|end▁of▁sentence|>.

Downloading the Model
You can download the model using the huggingface-cli tool. Here’s an example of how to download the model:
huggingface-cli download legraphista/DeepSeek-V2.5-IMat-GGUF --include "DeepSeek-V2.5.Q8_0.gguf" --local-dir./
Note that the model file is split into multiple files, so you’ll need to download all of them to use the model. You can find more information about downloading the model in the Downloading section.
Merging Split GGUF Files
If you’ve downloaded a split GGUF file, you’ll need to merge the files using the gguf-split tool. Here’s an example of how to merge the files:
gguf-split --merge DeepSeek-V2.5.Q8_0/DeepSeek-V2.5.Q8_0-00001-of-XXXXX.gguf DeepSeek-V2.5.Q8_0.gguf
