Kimi Code 0.29.0 adds granular thinking effort levels (off, low, medium, high) selectable from your editor instead of a simple toggle. Custom agents can now be defined as Markdown files with frontmatter and used as main or sub-agents. Videos attached to prompts now upload directly with your message and remain playable after chat reload. User-level system prompt overrides are supported for every session. The models catalog importer now handles many more providers, filters deprecated models, and correctly applies context limits and endpoint configurations.
