GLM-5.3 vs MiniMax-M3 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
Z AI / GLM-5.3
proDescription
Z.ai's coding-focused flagship, built for software engineering and long-horizon agent work. GLM-5.3 builds on GLM-5.2 through extended post-training rather than a new base model, with its largest gains in agentic, tool-driven development and a new emphasis on cybersecurity work like finding software vulnerabilities. It holds a very large context and offers adjustable thinking effort. Text only. Open weights under an MIT licence, so it can be self-hosted.
MiniMax / MiniMax-M3
proDescription
MiniMax’s flagship, and the first open-weight model to combine frontier coding, a million-token context, and native multimodality in one place. M3 reads text, images, and video, and can operate a desktop computer. Multimodal training ran from step zero rather than being bolted on later. Weights are open. Built for long-horizon agent work that runs for hours rather than seconds.

Z AI / GLM-5.3
proAgentic Software Engineering
Z.ai reports its biggest improvement here, training on realistic multi-step environments rather than short exercises. Built for multi-file changes and sustained work across a project, with strong open-model results on agentic coding.
Effort Up To Max
Three thinking-effort levels, low, high, and max, with max the default and recommended for coding. Note that thinking cannot be switched off entirely, a change from the previous generation.
Room For Repositories
A very large context window, unchanged from GLM-5.2. Hold a large codebase or a long agent history in a single session and work across all of it without breaking the task into pieces.
Structured Engineering Output
Built to plan, implement, test, and verify across long tasks, producing working changes rather than prose. Suited to real engineering deliverables rather than long-form writing.
Cybersecurity Research
New to this release. Z.ai reports strong results on vulnerability-discovery benchmarks, reasoning across full analysis chains rather than isolated bugs. It has no native web search, so current data comes through connected tools.
Text Only Input
Reads and writes text. No image, audio, or video input. Screenshots, diagrams, and scanned pages are outside what this model can read, which rules it out for visual work.
MiniMax / MiniMax-M3
proFrontier Coding in an Open Model
MiniMax reports significant gains over the previous generation in bug fixing, front-end and back-end development, and performance optimisation, approaching leading closed-source models. Autonomous task decomposition and tool invocation are built in.
Thinking You Toggle Per Request
Thinking mode can be switched on or off at request time, and supports interleaved thinking blocks. Turn it off for routine work, and on when a task needs multi-step reasoning before the answer.
Room for Repositories and Logs
Up to a million tokens, with a guaranteed minimum of 512,000. MiniMax built this for long-range agent tasks, whole-codebase work, and long-video understanding, so paper, code, and logs fit at once.
Writing From Charts and Papers
Reads charts, curves, and formulas directly from source documents and writes from them. MiniMax demonstrated it reproducing a research paper unaided, producing commits and experimental figures across a twelve-hour run.
Autonomous Research and Browsing
MiniMax reports strong autonomous browsing and information retrieval, plus agentic performance on office workflows including search and Office-suite tasks. Suited to research that requires finding material, not just reading it.
Images, Video, and Computer Use
Text, image, and video input, natively. MiniMax's API accepts image and video content parts directly. It can also operate a desktop computer, which is rare in an open-weight model.
