New LLMs like GLM-5.3-Flash, DeepSeek V4, and Kimi K3 are offering context windows of approximately 1 million tokens, a significant leap from the typical 128K-200K range. This expanded context allows for tasks such as analyzing entire codebases, processing lengthy transcripts with accompanying materials, and synthesizing large document sets in a single pass. While this enables more reliable multi-file code refactoring and long-horizon software engineering, users must still consider the cost of filling these large context windows and the limitations of output token budgets.
