Kimi K3 vs Grok Build 0.1 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
Kimi / Kimi K3
proDescription
Moonshot AI's flagship and the successor to the K2 line, built for work that runs long. Kimi K3 reasons on every request with adjustable effort, holds an entire repository in one session, and reads images and video natively. Built for long-horizon coding, agentic workflows, and visual engineering. Moonshot notes it can act proactively when instructions are ambiguous, so clear direction helps.
xAI / Grok Build 0.1
proDescription
xAI's coding model, purpose-built for autonomous software engineering rather than chat. Grok Build 0.1 acts as an engineering agent: it reasons through a problem, writes code, runs your terminal, checks for errors, and fixes its own mistakes in a loop. It reads text and images, always reasons before answering, and natively supports Model Context Protocol. Built for long-horizon coding that runs with little supervision, at a low cost, tuned for agent loops.

Kimi / Kimi K3
proCoding With Live Feedback
Moonshot invested most heavily here. Built to navigate large repositories, use tools, debug, and iterate against images, logs, tests, and runtime feedback with limited supervision.
Always-On Adjustable Reasoning
Reasoning runs by default on every request, with effort, you can dial up or down. Fast tasks stay quick while hard problems get the depth they need.
Massive Context Recall
Holds a full mid-sized codebase or a long document set in a single prompt. Its hybrid linear attention is what keeps a window that large affordable to serve.
Knowledge Work Artifacts
Built to produce complete software or knowledge-work artifacts with limited supervision, rather than returning text you assemble afterwards. Suited to research synthesis, document review, and technical documentation.
Multi-Step Research
Conducts multi-step research and coordinates terminal tools, carrying a task through from start to finish. A swarm variant coordinates large numbers of parallel sub-agents for wide research.
Native Image And Video
Processes text, images, and video within the same model rather than bolting on a separate vision module. Moonshot highlights frontend engineering, game development, and CAD workflows.
xAI / Grok Build 0.1
proAutonomous Engineering Agent
Purpose-built to act as an engineering agent, not a code generator. Refactors across a codebase, invokes tools, runs tests, and iterates through multi-step development tasks, picking up your project conventions as it works.
Reasoning Always On
Every response includes structured reasoning before the final output, and effort is not configurable. Built for deliberate, multi-step work rather than instant answers, so it plans before it acts.
Repository-Scale Context
A large context window, roughly 190,000 words, is sufficient to hold a substantial codebase or a long agent history in a single session. Reporting notes no fixed output cap, so it can refactor large files in one go.
Structured Code Output
Supports structured outputs and a JSON schema, so it slots into agent pipelines and developer tooling. Built to produce parseable, tool-ready output rather than long-form prose.
Native MCP And Tool Use
Natively supports Model Context Protocol, so internal knowledge bases, proprietary APIs, and MCP servers plug in directly. Built to work inside existing developer tooling rather than a closed ecosystem.
Text And Image Input
xAI lists text and image input, with text output. Send source code, diagrams, UI mockups, or error screenshots in the same request. Audio and video are not supported.
