Context length for Deep research
Deep Research uses a context length of 128K tokens (approximately 200,000 words).
This means Kimi-Researcher can process and reference a substantial volume of text in a single research task — more than enough to support complex, in-depth report generation.
Tip: If your research question is too broad, consider breaking it into multiple sub-questions and researching them separately. This improves the depth and accuracy of each individual task.
