Overview

Kimi K2.7 Code is Moonshot AI's frontier-scale open-source model — a 1-trillion-parameter mixture-of-experts architecture purpose-built for agentic coding workloads. It pairs a 262,144-token context window with multi-turn tool calling, native reasoning, vision inputs, and structured outputs, making it well-suited for long-horizon software-engineering tasks that span large codebases and many tool invocations.

The model is designed for autonomous coding agents: it can plan a change across many files, call tools to read and edit code, run tests, and iterate — all while keeping the full project context in its very large window. Vision input lets it work from screenshots, diagrams, and design mockups, and structured output keeps tool-call payloads reliable.

Served through CallMissed on Cloudflare Workers AI, K2.7 Code is OpenAI-compatible (`/v1/chat/completions`) with streaming, full tool calling, and a `reasoning_effort` thinking toggle.
