Grok 4.3 vs Hy3 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
xAI / Grok 4.3
proDescription
xAI's previous flagship, and still the Grok model with the largest context window. Grok 4.3 holds a million tokens, double what the newer generation offers. xAI positions it around a low hallucination rate, agentic tool calling, and instruction following. It reads text and images, searches the web and X, and lets you turn reasoning off entirely when speed matters more than depth.
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.

Why Use Grok 4.3 and Hy3?
Aymo gives you more than access to individual models—it provides a complete multi-model AI workspace designed for productivity.
xAI / Grok 4.3
proAgentic Coding and Tool Calling
xAI positions this model on agentic tool-calling and instruction-following, which is what coding agents actually run on. Function calling and structured outputs are both supported natively.
Reasoning You Can Switch Off
Effort runs at none, low, medium, or high. None means no reasoning at all, so you can drop it entirely for simple work and pay only for the answer rather than the thinking.
Large Context Window
Handles a one million tokens, twice the window of the newer Grok generation. Load an entire repository or a large document set in one pass. Requests above 200,000 tokens are billed at a higher rate.
Low Hallucination
xAI leads its own description with non-hallucination rate and instruction-following, which matter most for writing that has to be accurate and stay within the brief you gave it.
Web Search and X Search
xAI states that Grok knows nothing beyond its training data and provides server-side Web Search and X Search tools to bridge the gap. X Search reaches posts and threads no other model can read.
Text and Image Input
xAI lists modalities as text and image in, text out. Send screenshots, diagrams, or scanned pages alongside your prompt. Audio and video are not listed as accepted 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.
