Z AI / GLM-5.3
proDescription
GLM-5.3 is Z.ai's coding-focused model, grouped in the Pro tier on Aymo. It builds on GLM-5.2 through extended training rather than a new base model, with the largest gains in agentic, tool-driven work.
Chat with it for software engineering, long-horizon agent tasks that span many steps, and, new to this release, cybersecurity work such as finding software vulnerabilities. It offers three thinking-effort levels, so you can trade speed for depth depending on how hard a task is, and it holds a large amount of context in a single conversation to support work across large codebases.
It's text-only, so any task involving images or video needs a different model on Aymo. For everyday, lighter work, a smaller model is more economical, but GLM-5.3 is built for demanding coding and agent workflows.

Why GLM-5.3
Why Use GLM-5.3?
Aymo gives you more than access to GLM-5.3—it provides a complete multi-model AI workspace designed for productivity.
Agentic Coding
Run coding agents through long, multi-step tasks, the area Z.ai reports as GLM-5.3's biggest improvement over its predecessor.
Software Engineering
Work through real-world software engineering tasks, from multi-file changes to sustained code modification across a project.
Cybersecurity Work
Use it for security-focused tasks like finding and reasoning about software vulnerabilities, a new emphasis in this release.
Adjustable Effort
Choose from three thinking-effort levels to match the model's depth to the task, from quick work to complex problems.
Large-Context Coding
Hold a large codebase or long agent history in a single conversation without breaking the work into pieces.
Open-Weight Model
Use a fully open-weight coding model, which outside Aymo can also be self-hosted for teams with the infrastructure.

Claude Fable 5.1
Anthropic
Anthropic's most capable model available. Built for the hardest coding, research and long agent tasks, with a million-token context. Use it when quality matters more than cost.
Gemini 2.5 Flash-Lite
Google's lowest-cost Gemini. Good for quick replies, simple questions and high-volume chat where speed and price matter most.
GPT-5 Nano
OpenAI
Very fast and very affordable. Good for quick lookups, summaries and simple everyday questions.
Grok Build 0.1
xAI
xAI's coding model, built for agent-style software work. It always reasons before answering, reads screenshots and diagrams, and handles refactors, debugging and multi-step coding tasks at a low price.
FAQ
Frequently Asked Questions
Everything you need to know about using GLM-5.3 on Aymo AI.
Agentic coding, real-world software engineering, and cybersecurity tasks like vulnerability discovery, especially long, multi-step work.
Yes. You can try GLM-5.3 on Aymo, with your first conversation covered by free credits. Higher limits come with paid plans.
Yes, coding is its entire focus. Z.ai positions it as one of the strongest open-weight coding models, with its biggest gains in agent-driven development work.
Select it from the model selector in any chat and send your text-based coding prompt. Switch to a multimodal model mid-thread if your task involves images or video.
No. It runs on your Aymo plan with no separate Z.ai account needed. If you'd rather use your own Z.ai account, BYOK supports that on qualifying plans.
GLM-5.3 builds on the same base as GLM-5.2 with stronger coding and agentic performance, plus a new focus on cybersecurity work. Use GLM-5.3 for the latest gains and GLM-5.2 if you have a reason to stay on it.
