DeepSeek-V4: Towards Highly Efficient Million-Token Context Intelligence DeepSeek-AI research@deepseek.com Abstract We present a preview version of DeepSeek-V4 series, including two strong Mixture-of- parameters (49B activated) and DeepSeek-V4-Flash with 284B parameters (13B activated) both supporting a context length of one million tokens. DeepSeek-V4 series incorporate several key upgrades in architecture combines Compressed Sparse Attention (CSA) and Heavily Compressed Attention (HCA) to improve long-context efficiency; (2) Manifold- Constrained Hyper-Connections (mHC) that enhance conventional residual

### 4.4 Problems after installation • On Windows ImportError: DLL load failed while importing _fitz. This has been occasionally seen if MSVCP140.dll is missing, and appears to be caused by a bug in directory is not the PyMuPDF/directory. Otherwise, confusingly, Python will attempt to import fitz from the local fitz/ directory, which will fail because it only contains source files. ### 4.7 Running tests to 1.24.2. ## THE BASICS ### 5.1 Opening a File To open a file, do the following: import Fitz doc = Fitz.open("a.pdf") # open a document ## Note: Taking it further See the list of supported

## PyMuPDF Documentation • Introduction Note on the Name fitz License Covered Version ## • Installation Option 1: Install from Sources Step 1: Download PyMuPDF ■ Step 2: Download and Generate While PyMuPDF has been available since several years for an earlier version of MuPDF (v1.2, called fitz-python then), it was until only mid May 2015, that its creator and a few co-workers decided to elevate link handling and document or page creation. ## Note on the Name fitz The standard Python import statement for this library is import fitz. This has a historical reason: The original rendering library
