Grok 4.5 vs Hy3 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
xAI / Grok 4.5
proDescription
xAI's frontier model, built for coding, agentic tasks, and knowledge work rather than conversation. Grok 4.5 reads text and images, searches both the web and X, and lets you set how hard it thinks before answering. Its knowledge runs to February 2026, unusually recent. The tradeoff is context: its window is half the size of the previous Grok generation.
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.

xAI / Grok 4.5
proCoding and Agentic Tasks
xAI was built specifically for coding and agentic tasks, trained on new datasets spanning science, engineering, and maths. Aimed at multi-file work across repositories.
Reasoning Effort You Control
Reasoning runs at low, medium, or high, so you decide how much thinking each request gets. Function calling and code execution are supported, which is what agentic work actually depends on.
A Mid-Size Context Window
Handles 500,000 tokens, roughly 375,000 words. Comfortable for large codebases and long document sets, though half the window the previous Grok generation offered, so whole-monorepo work may not fit.
Knowledge Work and Documents
xAI positions it for knowledge work alongside coding, which means long documents, structured reasoning, and the kind of writing that has to survive review rather than just read well.
Web Search and X Search
xAI states plainly that Grok knows nothing beyond its training data, and provides server-side Web Search and X Search tools to fix that. X Search is unique to this model.
Text and Image Input
Reads text and images, in jpg or png, in any order alongside your prompt. Send screenshots, diagrams, or scanned pages. Audio and video are not listed as supported inputs.
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.
