Kimi K2.7 Code vs GPT-5.4 Nano Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
Kimi / Kimi K2.7 Code
proDescription
Moonshot AI's coding-specialized model, built on K2.6 for end-to-end software engineering. Kimi K2.7 Code is shaped around real developer work: reading a repository, planning a multi-file change, running tools, and debugging across many steps. It reads text, images, and video, always reasons before answering, and Moonshot reports it using notably fewer reasoning tokens than its predecessor. Text-focused coding, with a large context. Open weights under a modified MIT license.
OpenAI / GPT-5.4 Nano
proDescription
OpenAI's smallest and cheapest current-generation model, built for speed and volume. GPT-5.4 Nano excels at classification, data extraction, ranking, and coding sub-tasks, and works well as a fast sub-agent inside larger systems. It reads text and images, supports web search, and follows instructions reliably. Reasoning depth is shallow by design, traded for very low latency and cost at scale.

Kimi / Kimi K2.7 Code
proEnd-To-End Coding
Moonshot's most capable coding model, purpose-built for repository-scale work: multi-file changes, refactors, and debugging over long agent sessions. Reports higher end-to-end success rates on real software engineering than K2.6.
Efficient Mandatory Thinking
Always reason before answering, with no non-thinking mode. Moonshot reports roughly 30% fewer reasoning tokens than K2.6 and less overthinking, which compound into real savings across long agent runs.
Repository-Scale Context
A large context window, roughly 190,000 words. Enough to hold multiple source files, configuration, documentation, and a long agent transcript at once, without chunking a real codebase.
Reliable Instruction Following
Moonshot emphasizes reliable instruction following across long contexts, carrying a task through to completion. Built for structured coding work and tool output rather than long-form prose.
Multi-Step Tool Use
Supports multi-step tool invocation, reasoning, planning, and acting across multiple steps. It can even inspect a video clip through a tool called to reason about timestamps, useful for debugging UI or recorded test runs.
Text Image And Video
A MoonViT vision encoder gives it native image and video input alongside text, with text output. Unusual for a coding model, and useful for turning screenshots or recordings into fixes.
OpenAI / GPT-5.4 Nano
proCoding Sub-Agents
OpenAI positions it for coding sub-tasks and as a fast sub-agent in multi-model architectures. Built for small, well-scoped jobs run at high frequency rather than whole engineering problems.
Adjustable Reasoning Effort
Reasoning effort ranges from minimal to high. Even at higher effort, it is a shallow reasoner by design, so it suits speed-sensitive work rather than hard multi-step problems.
Room For Long Inputs
A large context window, enough to classify or extract from big batches of text in a single pass. Ample for the high-volume work it is built for without splitting the input.
Extraction And Ranking
OpenAI names classification, data extraction, and ranking as its core uses. Built to process structured, repetitive text work quickly and cheaply rather than to write long-form content.
Web Search For Current Facts
Supports web search as a tool, so it can pull live information into an answer. Useful in background and real-time systems where the data needs to be current.
Text And Image Input
Reads text and images, so you can send screenshots or scanned pages alongside your prompt. Output is text only. Audio and video are not supported.
