Kimi K3
A long-context model for documents, coding, visual tasks, and extended tool workflows.
Kimi K3 · Limited upstream availability
Overview
Kimi K3 is a multimodal reasoning model for coding, knowledge work, and long-horizon agentic workflows.
In Aether, it is a useful alternative when a task involves a large document, a substantial codebase, or many connected steps.
+Pros
- Very long context
- Strong coding and visual reasoning
- Designed for extended multi-step execution
-Cons
- Long-context capability is not automatically better for a small prompt
- Extended tool workflows can take longer and still need supervision
Best suited to
Large document analysis
Coding across multiple files
Long-form writing
Extended tool workflows
Aether Workspace Position
Available in Aether, although upstream capacity is currently limited and the model may return 429 errors.
Aether can choose Kimi K3 for large documents, multi-file coding, visual coding, and extended tool-oriented tasks.
