GLM-5.1 vs Hy3 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
Z AI / GLM-5.1
proDescription
Z.ai's flagship for agentic engineering, built to keep working rather than answer quickly. Z.ai says GLM-5.1 can run autonomously on a single task for up to eight hours, planning, executing, and revising as it goes. Strong on coding, office documents, and creative writing. Text only, with no image input, and a context window smaller than the largest frontier models. Open weights under an MIT licence.
Tencent / Hy3
lightDescription
Tencent’s open-weight reasoning model, built for agents rather than chat. Hy3 blends fast and slow thinking, switching between quick replies and deep reasoning, and Tencent tuned it hard for real production work: tool use, long agent loops, and search. It activates only a fraction of its parameters per token, so it is unusually cheap to run for its capability. Text only. Open weights, Apache 2.0.

Z AI / GLM-5.1
proCoding For Hours
Z.ai optimised it for agentic coding, with long-horizon planning, stepwise execution, and course correction mid-task. Suited to real engineering work with several stages and strong dependencies, rather than isolated snippets.
Thinking On Off
Reasoning is enabled by default and can be switched off entirely. Z.ai describes stronger instruction following, richer multi-turn responses, and better long-context understanding than the previous generation.
Mid-Size Context Window
A mid-size context window. Comfortable for long reports, contracts, and codebases, though a fraction of the capacity of the largest frontier models, so very big corpora need splitting.
Documents And Fiction
Z.ai highlights improvements across PowerPoint, Word, PDF, and Excel tasks, with better layout, plus stronger literary expression, plot development, and style control for fiction and copywriting.
Open-Ended Instructions
Z.ai reports stronger performance on open-ended questions, complex instruction-following, and multi-turn interactions, with more complete answers. Well-suited to everyday assistance and multi-stage information work.
Text Only Input
Z.ai's documentation lists GLM-5.1 as text-in, text-out. It does not accept images, audio, or video. Screenshots, diagrams, and scanned pages are outside what it can read.
Tencent / Hy3
lightProduction Software Engineering
Tencent reports strong software development, front-end design, and even game production, refined through its own WorkBuddy and CodeBuddy products. It concedes repository-scale coding to the strongest open rival but performs well on real, shippable work.
Fast And Slow Thinking
A hybrid reasoning design with selectable effort: a no-think mode for quick replies, and deeper modes for hard problems. That lets you spend reasoning only where a task needs it, keeping simple steps fast and cheap.
Long-Context Retrieval
Holds a large context and is tuned to parse messy, lengthy input while following complex rules. Tencent reports it powering agent workflows of hundreds of steps without losing the thread.
Office And Productivity Work
Tencent highlights office productivity, financial modelling, and document generation, including PowerPoint creation through its Yuanbao product. Built for structured, real-world business output rather than long-form prose.
Agentic Search And Tool Use
Its standout strength. Tencent reports leading the open field on agentic search and tool orchestration, retrieving, filtering, and integrating information across sources. Works with agent frameworks like OpenClaw, OpenCode, and Cline.
Text Only Input
Reads and writes text. No image, audio, or video input. Despite the Hunyuan family including media models, Hy3 itself is a pure reasoning and agentic language model, so screenshots and diagrams are outside what it reads.
