DeepSeek-V4 has been released with a million-token context window, a significant increase that shifts the challenges in building AI agents. While this long context removes the previous constraint of fitting information into smaller windows, it introduces new problems such as the model struggling to find relevant information within the vast amount of data. Effective use of this capability involves selective application for tasks like single-shot analysis of large codebases or maintaining active conversation history, rather than simply dumping all data into the context.
