KwaiKAT: KAT-Coder-Air V2.5 - access through LLMTR

KAT-Coder-Air V2.5 is the lighter, cost-efficient option in the KAT-Coder family. It brings the same agentic design as Pro to high-volume coding workflows that need spend kept in check: browsing a codebase, editing files, using tools, and running multi-step tasks. It reasons step by step before answering (reasoning is always on), makes tool/function calls, and accepts image input as base64 data URLs. It supports a 256K context window and prompt-cache reads.
